A. Introduction

Given Idaho State University (ISU)’s mission in Health Education and supporting disciplines such as the biological sciences, research and instruction involving the use of animals is often warranted. ISU’s Animal Care Facility is designed to assist both researchers and academic users in accomplishing their work, and in complying with government regulations, applicable laws, and standards for care and use. As used herein, "animal" refers to any living vertebrate animal (there are a few exceptions involving stages of development in certain creatures such as tadpoles and chickens; consult with the Animal Facilities Manager if you have questions in this regard).

Animal Care Facility resources include a main facility and various satellite locations. It has or can provide suitable housing for a variety of small animal species (mammals, birds, reptiles, amphibians, and fish), individually or in colonies. The Animal Care Facility is fully accredited by the non-profit organization known as AAALAC, which means ISU has high standards for care, usage, security, and management of animals. Having AAALAC accreditation is beneficial for obtaining external funding for research, and for ensuring the animal care follows the best of research and instructional practices.

This Handbook is intended to guide you through ISU’s policies and procedures concerning animal use. Note that this Handbook covers all animal usage by ISU personnel – i.e., animals do not necessarily have to be housed in a unit of the Facility to fall under the policies and procedures expressed herein. For example, researchers studying wild animals “in the field” will still have to file for approval of their protocols, etc.

This Handbook is divided into three parts totaling 12 chapters, covering topics that include administrative oversight, what animals are covered by these policies, proper husbandry and veterinary care, ethical and humane considerations, the responsibilities of faculty and staff using animals, and more. It includes links to all required forms. There is an Appendix, including a glossary.

Given the complexity of pertinent laws and regulations, as well as the sensitivity of the subject matter, this Handbook seeks to balance required thoroughness with both clarity and brevity. The ISU Office of Research and/or Institutional Animal Care and Use Committee (IACUC) invite you to provide feedback on any of these three areas, so as to improve revisions.

B. Faculty and Investigator Responsibilities

While this Handbook pertains most directly to individuals using animals in teaching or research, it also has a broader audience. In many fields, including biological sciences, instructing students in proper animal care and use is an essential component of education. As a matter of education policy, even faculty who do not use animals should be aware of the regulations and policies in this Handbook, since their students may use animals at a later time.

Individuals using animals in teaching or research (including field work involving animals) are, by law, accountable for conforming to basic regulations and policies governing animal use. There are multiple points of origins of such regulations and policies, from a variety of federal, state, and local sources. ISU has drawn on all these sources to develop this Handbook. As suggested by the Handbook’s Table of Contents, the topics of concern are wide-ranging, including but not limited to:  (a) the acquisition, care and use of animals, (b) efforts to minimize animal pain and distress, (c) the training of personnel using animals, (d) consideration of alternatives to animal use, and (e) obtaining approval of protocols.

Faculty and Investigators using animals in teaching or research are responsible for reading, understanding, and adhering to the policies and procedures laid out in this Handbook. Such Faculty and Investigators are also responsible for ensuring any of their subordinate staff or students caring for, working with, or having access to the animals also understand and comply with these policies and procedures.

Before Faculty or Investigators can obtain animals or make use of ISU’s Animal Care Facility, they will have to sign an acknowledgment that they have read and understood the policies and procedures laid out in this Handbook. Failure to comply with the provisions of this Handbook can result in disciplinary action, up to and including dismissal. If the underlying laws and regulations upon which the Handbook is based (e.g., Animal Welfare Act, USDA and APHIS policy) are violated, the result may also include civil or criminal prosecution. In some cases, violations may also lead to the suspension of funding and/or animal research activities, not just for the offender, but also for his/her colleagues or even the entire University.

Any concerns or issues regarding the proper treatment of animals used for research or instruction may be reported to the IACUC or any of its individual members.

C. Ethical and Humane Considerations in the Use of Animals for Research and Teaching

Scientists, theologians, philosophers and the lay public have debated questions concerning the ethics of using animals in research and teaching since the use of animals for such purposes began.  Even when consideration is restricted to recent discussions of the issue, there are almost as many ethical positions as there are writers on the subject.  The prevailing view is that animals can and should be used in research provided that certain key conditions are met:

 

Directly or indirectly, these concerns are repeated themes throughout this Handbook. They should be considered by faculty and researchers when they are designing their projects and developing protocols. This Handbook is but one resource to assist you with these considerations; you are also invited to contact ISU’s Institutional Animal Care and Use Committee, the Animal Facilities Manager, and/or the Attending Veterinarian for help or clarification, as appropriate.

D. US Government Principles for the Utilization and Care of Vertebrate Animals Used in Testing, Research, and Training

The principles below were prepared by the Interagency Research Animal Committee.  All ISU research and instructional use of animals must conform to these Principles.

I.     The transportation, care, and use of animals should be in accordance with the Animal Welfare Act (7U.S.C.2131 et seq.) and other applicable Federal laws, guidelines and policies. 
     
II.    Procedures involving animals should be designed and performed with due consideration of their relevance to human or animal health, the advancement of knowledge, or the good of society.
  
III.  The animals selected for a procedure should be of an appropriate species and quality and the minimum number required to obtain valid results. Methods such as mathematical models, computer simulation, and in vitro biological systems should be considered.
  
IV.  Proper use of animals, including the avoidance or minimization of discomfort, distress, and pain when consistent with sound scientific practices, is imperative.  Unless the contrary is established, investigators should consider that procedures that cause pain or distress in human beings may cause pain or distress in other animals.
  
V.    Procedures with animals that may cause more than momentary or slight pain or distress should be performed with appropriate sedation, analgesia, or anesthesia. Surgical or other painful procedures should not be performed on unanesthetized animals paralyzed by chemical agents.
  
VI. Animals that would otherwise suffer severe or chronic pain or distress that cannot be relieved should be painlessly killed at the end of the procedure or, if appropriate, during the procedure.
  
VII. The living conditions of animals should be appropriate for the species and contribute to their health and comfort. Normally, the housing, feeding, and care of all animals used for biomedical purposes must be directed by a veterinarian or other scientist trained and experienced in the proper care, handling, and use of the species being maintained or studied. In any case, veterinary care shall be provided as indicated.
  
VIII. Investigators and other personnel shall be appropriately qualified and experienced for conducting procedures on living animals. Adequate arrangements shall be made for their in-service training, including the proper and humane care and use of laboratory animals.
  
IX. Where exceptions are required in relation to the provision of these Principles, the decisions should not rest with the investigators directly concerned but should be made, with due regard to Principle II, by an appropriate review group such as an institutional animal care and use committee. Such exceptions should not be made solely for the purpose of teaching or demonstration.

E. Administrative Oversight of Animal Care and Use at ISU

Federal regulations (i.e., Animal Welfare Act, PHS Policy, etc.) stipulate the basic structure for overseeing animals care and use in university research programs. At ISU, the authority and responsibility for administering the animal program and ensuring compliance with the NIH Office of Laboratory Animal Welfare (OLAW) Assurance are as follows:

org chart

Institutional Animal Care and Use Committee (IACUC): IACUC (pronounced Aye-ah-kook) is a generic name for this type of committee, as well as the specific name for ISU’s committee. It is the backbone of the University’s animal care and use program oversight. IACUC’s functions include:

 

The committee is appointed by ISU’s Institutional Official (below). It must be composed of at least five members, including an individual unaffiliated with the institution, a veterinarian with program responsibilities, a practicing scientist experienced in research involving animals, and a non-scientist. It must be headed by a chairperson (who cannot be the Attending Veterinarian).

Institutional Official (IO): Generically, this is the administrator to whom an IACUC reports, and is either the university’s president or his designee. At ISU, the President has designated the Vice President for Research to fulfill this role. Note, however, while the IACUC reports to the Institutional Official, that official does not have unfettered power over the Committee. For example, to quote from an OLAW website: “Nothing in the PHS Policy precludes the Institutional Official or another authorized official from unilaterally suspending, terminating, or imposing sanctions on any activity involving animals, regardless of whether it was previously approved by the IACUC. However, no Institutional Official may approve animal activities or reinstate animal activities that were suspended by the IACUC.”

Animal Facilities Manager: The Animal Facilities Manager (AFM) is responsible for the day-to-day management of the Animal Care Facility and its staff. In general, the AFM is the “go-to” person should you have questions or concerns about animal care operations, need assistance in obtaining proper veterinary care, etc.
Certain activities discussed require going through the AFM. Only the AFM may purchase animals, and the AFM is also responsible for arranging suitable housing. Any transportation of animals must be coordinated with the AFM. Any deviation from standard diets must bearranged through the AFM. If you wish to involve any outside groups with the Animal Care Facility, you must make arrangements in advance through the AFM. The AFM serves as your liaison to the Attending Veterinarian and the IACUC. The AFM may also assist in providing veterinary and diagnostic services. The AFM can also arrange for training in animal care for faculty, research assistants, students, or project staff, if desired/required. During the development process of a project, the AFM can help develop appropriate budgets for animals and related equipment, and aid in the design of Animal Use Protocols before submission to the IACUC.

F. ISU Animal-Related Training Programs

 

At minimum, all users of animals at ISU must complete the Core Training program described below. Also, before any work with animals may begin, it is the responsibility of the faculty member or investigator to make sure any students or staff accessing the animals have the proper and appropriate training.

Training may be required for legal reasons, or to meet educational objectives. In some cases, the faculty member or investigator may wish to have, or be required to, undergo additional (customized, or one of the standard programs below) training themselves. For more information about customized training, please contact the IACUC Chair or the Animal Facilities Manager for assistance and/or referral.

ISU’s three standard training programs for those working with animals are: the mandatory Core Program, Animal or Use-Specific Training, and Occupational Health and Safety Instruction (OHSI). Each of these is described briefly below.

Core Training Program: This mandatory program has three components:

 

Participation in the Core Program is a prerequisite for any work (research or instruction) involving animals. IACUC will not approve any submitted protocols until the following outcomes of the Core Training are in place:

 

Occupational Health and Safety Instruction (OHSI): This program is designed to reduce the health risk (e.g., bites, venom, disease, etc.) to people using animals in research and teaching to an acceptable level. The entire OHSI program is in manual form, and is available in the Animal Facilities Manager’s office and here on the Animal Care Facility site. Content of the Training is summarized in the next chapter, Occupational Health and Safety Concerns. The specifics of the training is dependent upon the animal-use role of the person taking the training, as well as such variables as the species involved; it may take anywhere from a few minutes to a couple of hours to finish. Completion of OHSI training is verified by the Occupational Health and Safety Form referenced above.

 

Animal- or Use-Specific Training: In some cases, animal protocols call for procedures which may or do carry the potential of risk to the animal. On such occasion, the faculty member or investigator may, at the discretion of the IACUC, be required to obtain additional instruction or certification. Such instruction or certification may be obtained on a group or individual basis, depending on the specific situation. Likewise, instruction may be by direct instruction, or by the use of audio-visual materials covering the specific procedure, as appropriate to the circumstances. Instruction may be provided by the Attending Veterinarian, the Animal Facilities Manager, other Animal Care Facility personnel, or by faculty with expertise in the specific procedure.

G. Occupational Health and Safety Concerns

Many different kinds of physical, environmental, or biological hazards are associated with the use of animals in teaching, instructional training or research. The Centers for Disease Control, Code of Federal Regulations, Public Health Service, AAALAC, and others all have requirements for an occupational health program for people working with laboratory animals. The program must include: Hazard Identification and Risk Assessment; Personnel Training; Personal Hygiene; Facilities, Procedures, and Monitoring; Personal Protection; and Medical Evaluation and Preventive Medicine. These concerns are the basis of ISU’s mandatory OHSI Training.

           
Covered Personnel: Generally, “covered personnel” includes anyone involved in the direct care of animals and/or their living quarters; those individuals who have direct contact with animals (live or dead); their viable tissues, body fluids or wastes. Assessment of individual’s risk is determined by frequency of contact, intensity of exposure, hazards associated with the animals being handled, hazardous properties of agents used in research/instruction, the susceptibility of individual employees, the hazard-control measures available, and the occupational history of individual employees.

Specifically included are: Animal Care Facility staff, Investigators and their technical staff, and Instructors and students involved with animal related work. Also covered are some personnel in
facilities management, security, custodial services, and certain students, consultants, volunteers and visitors. IACUC provides an Occupational Health and Safety Form for each covered person to sign.
           

Exemptions: For situations where non-ISU students or ISU undergraduate or graduate students will be involved in ISU-supported programs, a request for variance from selected OHSI/medical criteria may be initiated. The participating Occupational Health Service Specialist (OHSS) will review such requests.
           

Investigator/Instructor Responsibilities:  The principle investigator or class instructor is responsible for informing all staff and students about the occupational health program.  All individuals covered under the program are to complete the Occupational Health and Safety Form.  The Animal Care Facility staff and IACUC are only responsible for the administration of the program, not to provide medical advice or care to individuals.

H. Animal Use Protocols

As used herein, Animal Use Protocol refers specifically to a document which must be submitted to ISU’s IACUC. The Protocol must be fully approved before the applicant may acquire, house, or use animals in any capacity.

Prior to Protocol Development: Please visit www.isu.edu/anmlcare/Policies.shtml and review the specialized policies posted there concerning specific species or other specific concerns. If your work involves any of these, you will be expected to adhere to them, and incorporate them into your Protocol accordingly. Familiarize yourself with them according to your needs.

Some research projects will require “sentinel animals” to monitor the population’s general health. Such animals are periodical euthanized and tested for disease; you may need to build this into both your protocol and project budget. If you have questions on this or other topics, the Animal Facilities Manager, staff, Attending Veterinarian, and IACUC members can assist you with clarification during the Animal Use Protocol development process. Their guidance may reduce delays in obtaining approval for your submission.

Who Must Submit an Animal Use Protocol: The lead researcher or faculty member for the animal project/program is to submit the Protocol, and be identified therein as the Principal Investigator (PI).

Protocol Content: The protocol form requires:

Thorough preparation of protocols facilitates the review process, reduces the chance of delay in initiating projects, and facilitates review by extramural funding agencies. A template for an Animal Use Protocol, instructions, sample of a completed form, and other material is available at http://www.isu.edu/anmlcare/protocol%20info.shtml.
The Protocol’s purpose is to give IACUC a clear and precise understanding of all proposed activities involving animals. IACUC needs to review Animal Use Protocols on a variety of levels (legal, ethical, medical, etc.). Preparing your Animal Use Protocol with IACUC’s needs in mind will facilitate their review and avoid unnecessary delays (information follows on common, easily-avoidable errors in preparing Animal Use Protocols). PIs with questions regarding protocol preparation should contact the Animal Facilities Manager or IACUC. The Attending Veterinarian, IACUC Chair, and the Animal Facilities Manager are available to review protocols prior to submission to the entire committee. This may also facilitate IACUC’s review process.

Timetable for Protocol Submission: Animal users must prepare and submit their protocols at least 7 days in advance of the scheduled meeting and well in advance of research proposal start date. Scheduled meeting dates are available on-line. IACUC meets once per month during the fall and spring semesters, and as-needed during the summer months. Protocols are submitted electronically to anmlcare@isu.edu. Note that no animals may be used or obtained until an approved protocol is in place.

Protocol Review Process: Each member of IACUC will review the protocol to ensure that all information and proposed animal use meet the standards set forth in The Guide and comply with requirements of the Animal Welfare Act and USDA Policy, PHS Policy, and University guidelines and policies.  The protocol is then voted upon by the IACUC.  The committee can:

 

 

Duration: Approved Protocols will be held on file as “active” for three years or until the project’s completion (whichever comes first).  Active protocols must be reviewed and updated yearly with a current literature search, current personnel statements, and any changes in procedures and/or reports of adverse events involving animals or personnel. It is helpful if the PI (i.e., the researcher or instructor in charge of project, as specified in the Protocol) sends IACUC a message when their project/protocol is complete.

Common Problems Encountered in Initial Protocol Submissions:

I. Design Considerations: Selecting Animals/Animal Models for Use in Research and Teaching

The use of animals in research and instruction generally occurs in one of two contexts: (a) the animals serve as model systems for the investigation of processes which cannot be studied directly, or (b) the animals are studied to investigate a problem specific to the particular species. Most biomedical research falls in category a. Examples of b include field studies of the behavioral and ecological adaptations of animal species, studies of taxonomic relationships among species, or captive studies of the physiological or behavioral processes which form an important part of the adaptations of one or more species. Selecting a Model for Research: Choosing an appropriate model must be based on extensive familiarity with the problem or system to be studied (so as to determine the range of biological responses necessary to the experimental design). This familiarity may be developed by either extensive review of the literature or from pilot studies. The lead researcher/instructor (herein after referred to as PI; i.e., the person listed as the PI on the Animal Use Protocol) can then proceed to select an appropriate model: a whole animal, tissue cultures, or non-animal. An animal model is a living organism in which normal biological processes can be studied, or in which a spontaneous or induced pathological process can be studied. To be effective, the process being modeled should closely resemble the analogous process in humans or some other species, in one or more ways. Some important criteria of animal models are: relevance to the problem being studied; the accuracy with which the model reflects all or some important aspects of the problem; the models predictability; and the models availability to researchers/instructors. In addition, general species characteristics such as life history parameters, behavior and diet can be as important as physiological parameters in species choice. Alternatives to the Use of Animals in Research: Critics of animal research have suggested that most, if not all, uses of animals in research and education could be eliminated by the use of alternatives such as tissue culture or computer models. In 1986, the US Congress Office of Technology Assessment produced an extensive study of the use of animal models and options for alternatives to animal use in research, education and testing. The general conclusion of the report was that the very nature of research in many areas makes it highly unlikely that reasonable alternatives to animal use will be developed. In some areas, however, alternatives exist or appear feasible to develop, and in some cases such alternatives may be more economical than the use of whole animals. Recent legislation has required alternatives to be considered. Alternatives can be divided into four broad categories:

   Return to top

J. Animal Acquistion, Housing, and Records

Acquisition and Housing: All arrangements for acquiring and housing animals from any source must be made through the Animal Facilities Manager. Per Diem charges will be assessed, with rates dependent upon species and number of animals housed – the Animal Facilities Manager should be contacted for the latest information on Per Diem charges. PIs (the lead researcher or instructor listed on the Protocol) are to include such costs in their project budget.

Prior to purchasing or acquiring animals, arrangements must be made with the Animal Facilities Manager, an approved Animal Use Protocol must be on file, any required permits obtained, and quarantine (if any) arranged. Unless immediately undergoing terminal procedures, all animals are to be acclimated to their new environment before any use (usually for three to seven days – see next chapter). Note that only the Animal Facilities Manager may purchase animals.

PIs requiring special care, equipment, or supplies for their animals, or any exemptions from standard animal care procedures, must have prior IACUC approval and must inform the Animal Facilities Manager so that appropriate arrangements can be made. PIs must notify the Animal Facilities Manager if their animals will be exposed to materials or procedures which may be hazardous to personnel.

Animal Transportation:  If animals are to be shipped or PI-transported from other than an approved/registered facility, the Attending Veterinarian and Animal Facilities Manager must be consulted beforehand. They will assist the PI in making sure transportation conditions and containers are species-appropriate and conform to pertinent standards, laws and regulations.

 

Animal Identification and Record Keeping: Appropriate identification of animals and maintenance of animal records is required. Accepted methods of animal identification include:

 

Identification cards should include the source of the animal, the strain or stock, the PI’s name and contact information, pertinent dates, and approved protocol number.  All animal’s records should accurately reflect all procedures performed, treatments, diagnostics, drugs or medications used (including dosages and times given), physiologic parameters, illnesses and injuries, any clinical or abnormal observations, and date of death, euthanasia, or final disposition. Individual animal records will be kept on all animals except rodents and ectotherms. Rodents and ectotherm will have one record for each colony. (Note: as used herein, “colony” refers to all the animals contained within a single animal room.)  Colony records will be kept in the animal room, or in the Animal Facilities Manager’s office.

The Animal Facilities Manager maintains individual clinical records for all species and maintains a colony record for rats and mice. However, all technicians, users (including Research Assistants) are all responsible for entering pertinent data on the records. These records are a means of communication between PIs and animal care personnel. All animal manipulations and drug use, as well as objective observations on health status, should be recorded by PIs and/or by animal care personnel. Current records will be maintained in the animals’ room; records of completed projects are retained in the office of the Animal Facilities Manager for three years.

K. Animal Husbandry and Veterinary Care

Husbandry: The Guide has established housing and husbandry standards, and ISU is committed to conforming to those standards. The Animal Facilities Manager is to select suitable cages or other housing, in accordance with The Guide. Environmental factors, such as temperature, humidity, ventilation, illumination, feed, bedding, sanitation, waste disposal, and vermin control are all important and necessary to providing optimal housing conditions for the animals. IACUC may approve environmental conditions that differ from the conventional situations only if strong scientific justification is established in the Animal Use Protocol.

Compiling and maintaining animal health records are the foundation of both husbandry and veterinary care. Record procedures provided in the previous chapter (“Animal Acquisition, Housing, and Records”), and are the joint responsibility of all staff and users.

 

Veterinary Care: The Attending Veterinarian maintains regular on-campus hours (~5 hours per week), and is available “on-call” to:

 

Acclimation and Quarantine: A plan for adequate quarantine and health surveillance/testing will be established prior to animals entering the facility. Rooms for such animals have additional restrictions concerning access by personnel; please discuss any concerns in this regard with the Animal Facilities Manager. The extent of any quarantine period is determined by the species and by knowledge of the animal’s source and previous history. In quarantine, animals will be separated by species. The isolation, quarantine and acclimation program for newly arrived animals is necessary to provide time to assess their health status, allow them to recover from the stress of shipment, have an opportunity to adapt to their new environment, and to minimize introduction of disease into the facility.

Arriving animals, regardless of source, must be allowed an acclimation period before use. Effects of transport, large temperature fluctuations, as well as changes in feed, water and housing conditions are physiological stressors which can impact both animal health status and research results. Acclimation times are three days for rodent species, seven days for non-rodent mammals, and as-needed for non-mammal species. Animals may be exempt from this policy only if they meet the following criteria:

 

Quarantine and surveillance is required for all animals from non-commercial sources. Colonies may be exempt only if they meet the following criteria:

 

Initial Health Status:  Upon arrival, Animal Care Facility staff will visually inspect each animal, reporting any concerns to the Attending Veterinarian. Rodents from vendors or approved outside sources (e.g., transferred from another university) must have accompanying health records. Fecal samples will be collected for medical testing during this initial inspection. Sentinel animals (if applicable) will be selected and placed in appropriate racks. (Sentinel animals are periodically euthanized and tested for disease as a means of monitoring colony health; PIs need to be aware that if sentinels are required, they must be included in their project budget. Questions concerning sentinel animals should be addressed to the Animal Facilities Manager or IACUC.) Non-rodents species will have an Initial Health Plan formulated by the Attending Veterinarian, Animal Facilities Manager, and the PI, based on species, source of animals, and risk to staff and other animals/colonies.

 

Surveillance, Diagnosis, Treatment and Control of Disease:  All animals will be checked daily in their rooms, including weekends and holidays. Signs of illness, injury, or abnormal behavior are reported to the Animal Facilities Manager. Daily records of monitoring are kept in the room. For rodents there is a specialized “Rodent Health Monitoring” document. As with the Initial Health Plan, the Attending Veterinarian, Animal Facilities Manager, and PI will formulate a plan based on species, source of animals, and risk to staff and existing colonies.

All health concerns are to be recorded and reported to Attending Veterinarian. After initial examination and evaluation, a plan will be formulated by the Attending Veterinarian with the PI and Animal Facilities Manager for diagnosis, treatment, and control. This may include euthanasia and necropsy, blood work or other diagnostic modalities, and removal/quarantine of individuals.

 

Anesthesia and Analgesia: The Attending Veterinarian, as an IACUC member, reviews procedures to ensure that proposed anesthetics and analgesics are appropriate for the species and research objectives. The Attending Veterinarian is available to provide assistance with, or training in, the proper administration and use of anesthetics.

Animals that may experience more than momentary or slight pain/distress require appropriate sedation, analgesia, or anesthesia unless there is suitable scientific justification. Assessment of pain and distress in animals is difficult and can be subjective. As such, procedures that cause pain/distress in humans should be assumed to cause similar effects in animals, unless the contrary is established. The Attending Veterinarian has the authority to ensure the provision of adequate sedation, analgesia, or anesthesia. The PI must provide in the Animal Use Protocol a detailed description of how pain or distress will be assessed and how agents will be used to alleviate pain and distress. When animals are subjected to major survival surgery, routine provision of post-surgical analgesia is required. If the PI feels it necessary to withhold sedatives, analgesics, or anesthetics, or to deviate from the recommendations of the veterinary staff, the PI must provide the IACUC a reasoned, scientific justification beforehand. The justification should include the rationale or evidence that the agents would compromise the scientific aspects of the research protocol. PIs are strongly encouraged to consult with the veterinary staff during Protocol planning, to reach agreement on appropriate use of drugs for control of pain and distress. The IACUC may also require animals be euthanized to avoid suffering if their condition is moribund, unless scientific justification is approved in the Animal Use Protocol (see glossary discussion of “Humane Endpoint”).
           
            MONITORING: All anesthetized animals must be continually attended and monitored to assess adequate level of anesthesia. There are many acceptable methods to monitor anesthesia.  The following lists the most common methods to show if an animal is too-lightly sedated:

 

All animals recovering from anesthesia must be constantly attended until they have recovered their protective reflexes (see Surgery, Care & Room Requirements, and Post-surgical Care below). With rodents and other small species, this is usually indicated by the animal starting to move around. All animals should be kept in appropriate environments (see “CARE” below) during recovery. With rodents, this can be accomplished by placing the animal under a heat lamp or on a heating pad, placing the animals in a cage warmed on a heating pad, or wrapping the animal in a small towel. Care must be taken to avoid overheating when using a heat lamp or heating pad. Whenever a heat source is used, a thermometer should be placed at the animal's level to monitor actual heat. Animals will overheat and can “sun burn.” Animals which have had any significant blood/fluid loss during surgery are to be provided with fluid or blood replacement during surgery and/or the anesthesia recovery period. In small rodents, this is best accomplished by intraperitoneal or subcutaneous means.

Surgery, Care & Room Requirements, Pre- & Post-surgical Care: Below are five types of general surgical procedures, each of which has different requirements:

            ROOMS & EQUIPMENT: Major surgical procedures on mammals other than rodents must be conducted in surgical facilities intended for that purpose, using aseptic techniques. These techniques include wearing sterile surgical gloves, gowns, caps and facemasks; using sterile supplies and instruments; and maintaining an aseptically prepared surgical field.

Minor surgical procedures on mammals other than rodents must be performed in an approved and suitably located/equipped area. Appropriate aseptic techniques for these procedures include a clean uncluttered work area, preparation of the surgical site including clipping of the hair, disinfection of the skin, draping the surgical site with sterile drapes, use of sterile supplies and instruments, and the use of sterile gloves and surgical mask by the person performing the surgery.

Non-survival surgery may be performed in a suitably located and equipped area.

            CARE: Prior to surgeries (indeed, as part of the Animal Use Protocol), a Care Plan must be in place, having been developed in consultation with Attending Veterinarian. As appropriate for the species, fasting of up to 12 hours may be required prior to anesthesia and surgery to prevent vomiting, aspiration, and problems associated with a distended intestinal tract. Post-surgical care includes observation to ensure uneventful recovery from anesthesia and surgery. The animal must be monitored for post-procedural complications; it may be returned to its housing only when protective reflexes have returned and the animal regains sternal recumbence, is swallowing and capable of holding its head up. The animal should be kept in an appropriate controlled environment (e.g., warm and dry for mammals, etc.); fluids, analgesics and antibiotics are to be administered as required. Incisions will be monitored daily (generally 7-10 days, as appropriate for the procedure and species), catheters or other devices will be monitored daily, daily observation of all animals for any other signs of complications, records of all concerns, treatments, or other post-operative procedures will be kept in animal rooms. Surgical wounds should be kept clean, and dressings changed as necessary to keep them clean and dry.

Subsequent care may include supportive fluids, analgesics, and other drugs as required; monitoring of the animal to include daily body temperatures; clinical observations for signs of pain, abnormal behavior, appetite and excretory functions, providing adequate care of surgical incisions and maintaining appropriate medical records.

 

Euthanasia: The Guide defines euthanasia as the act of killing animals by methods that induce rapid unconsciousness and death without pain or distress. Federal regulations require IACUC determine that methods of euthanasia used are consistent with the Report of the American Veterinary Medical Association Panel on Euthanasia (AVMA Panel Report).  Consultation of the most current AVMA Guidelines on Euthanasia is required prior to Protocol submission and approval. Unless a deviation is justified in the Protocol for scientific or medical reasons, methods should be consistent with the most current AVMA Guidelines on Euthanasia.

Personnel properly trained in the procedures and for the species in question should carry out euthanasia. Measures should also be taken to ensure that euthanasia is performed in a way that minimizes reactions among other animals that may be present. Protocols must contain a description of procedures designed to assure that discomfort and injury to animals will be in the conduct of valuable research and limited to that which is unavoidable. Therefore a PI must discuss in the Animal Use protocol criteria for allowing removal and euthanasia of animals if undue pain and distress is established. See discussion of Endpoints in the Glossary.

Death must be verified after euthanasia and prior to disposal. Use of a different and redundant method of euthanasia is recommended to verify death. Unintended recovery must be obviated by using appropriate dosages and methods, close monitoring, and/or secondary methods such as thoracotomy.

PIs may choose to have Animal Care Facility Personnel perform any euthanasia. The Animal Care Facility personnel require PIs or their designee to legibly complete and sign an euthanasia cage card for each animal or cage of animals to be euthanized. Every animal must have access to food and water and be housed within cage density guidelines until they are euthanized.

B. Underlying Regulations and Policies

This Handbook is based on a variety of laws, regulations, policies, and nationally-recognized standards for animal care and use. Only a few of the major underlying sources will be covered here, and briefly. Interested readers are invited to do their own on-line searches for further information, or to contact ISU’s Animal Facilities Manager for further information.
   
Animal Welfare Act (AWA): This federal law was enacted in 1966, with numerous amendments since. Its provisions are broad, including such topics as transportation, purchase, care and treatment of animals, whether they are used for research, exhibition, or to be sold as pets. Overseeing compliance with the Act is the responsibility of the US Department of Agriculture (USDA), especially the Animal and Plant Health Inspection Service (APHIS) Division. Under the Act, all research facilities using animals - including those at ISU - must register with the USDA, and comply with USDA and APHIS regulations. Facilities are subject to unannounced inspections by the USDA. Universities must also establish an Institutional Animal Care and Use Committee (IACUC, pronounced Aye-ah-kook) to oversee internal animal use, programs, and compliance with pertinent regulations.

Public Health Service (PHS) Policy: The Public Health Service, part of the US Department of Health and Human Services, has various policies and regulations, including the Policy on the Humane Care and Use of Laboratory Animals, for any institution receiving PHS funding.

Office of Laboratory Animal Welfare (OLAW): OLAW is a division of the National Institutes of Health (NIH). Any institution receiving PHS funds must file an Assurance with OLAW. ISU’s Assurance (number A3623-01) became effective in August of 1988. The Assurance commits the institution to compliance with all of the above laws, policies, and regulations, among others.

Guide for the Care and Use of Laboratory Animals: Hereinafter referred to as “The Guide,” it is published by the National Research Council, and compliance is required under ISU’s OLAW Assurance (see above).

US Government Principles for the Utilization and Care of Vertebrate Animals Used in Testing, Research, and Training: A set of nine guiding principles created by the Interagency Research Animal Committee, to be considered whenever involving animals in research or instruction.  These appear in full on page 4.

Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC): AAALAC is a private, international, non-profit organization that promotes the humane treatment of animals in science through voluntary accreditation and assessment programs. AAALAC provides the recognized benchmark standards for animal care and use.  ISU’s animal care and use program has achieved and maintained full accreditation by the AAALAC since 1990.
