Part 1: The Protocol Form

Protocol Identification
When selecting the “Academic Unit”, you are selecting the endorsers in your department that will be viewing your protocol during the pre-review process.

Rationale for Using Animals
In this section, the IACUC is looking for you to discuss why alternatives to live animal cannot be used.  For example:  Describe why computer models, tissue culture, or perhaps clinical studies cannot be used to complete the objectives of your Protocol Aims.  Simply stating that you need live animals is not an appropriate response.

Protocol Groups
In this section, you are creating the “breakdown” of your animals.  The groups you create in this section will also be used in upcoming sections (such as Protocol Activities and Justification for Number of Animals Requested).

Each species must be in a separate protocol group. Animals of the same species that undergo different protocol activities (procedures) should be in separate protocol groups. However, when there are different experimental groups (in the same species) that will undergo essentially the same activities, they may be combined in a single protocol group.

Assign a short, descriptive title to each protocol group. It should be easy for the reader to relate the protocol groups to the number of animals requested in the Justification for Numbers section. If protocol groups are actually comprised of several experimental groups, simply identify these within the Activity Timeline. These same experimental groups may be referenced again in the Justification for Numbers section to support the total number of animals requested under the (larger) single protocol group.

Try to minimize the number of groups you create.  This will help simplify the completion of upcoming sections.

Animal Sources
If “Obtained Internally: Breeding” is selected for a particular group, then a number must be present in the breeding portion of the upcoming section “Justification for Number of Animals Requested” (for that group).

If “Obtained Internally: Breeding” and any other source is selected for the same group, then a number must be present in both the breeding portion and the non-breeding portion of the upcoming section “Justification for Number of Animals Requested” (for that group).

Housing Locations
If non-ULAR housing is being requested, please visit the IACUC Guideline Housing Requirements for Animals for more information.

Activity Timeline
In this section, the Committee is looking for a sequential order for when protocol activities are taking place.  The Timeline is designed to indicate what protocol activities will happen, and when, to each group of animals.  For each group, you should include the series of treatments to be carried out starting with arrival/enrollment in the study, to final disposition. Do not include a detailed description of the procedures.  This information will be collected in the protocol activities section.

Along with the sequence of activities, the Committee is also looking for the time between each procedure and if procedures are to be repeated.  Example:  For chronic experiments, include how long animals will survive following a procedure as well as their final disposition.

The endpoint for all experiments needs to be clearly defined.  If death (without intervention) is being used as an endpoint, then the Committee expects a scientific justification to be included in this section explaining why this endpoint is needed.

Protocol Activities
The protocol you submit is a “stand alone” document.Do not refer to procedures in other protocols or publications or assume that they are so generally used that everyone will know what you will do.Select they type of Protocol Activity that best describes the procedure that is to be performed. Provide procedure descriptions in each of the Activities. Use the IACUC Guideline links that are provided for descriptions of commonly used procedures.  This section should correlate with what you included in Activity Timeline.

The Committee does not require descriptions of in vitro experiments. (These requirements are contrary to most grant applications. Therefore do not simply copy your grant application into the AUP.) It should be easy for the reader to relate the procedures (activities) to the experimental groups.

The Committee needs to have information on all details relating to injections of drugs, virus vectors, etc. including routes of administration, volumes, site of blood draw, number of bacteria/viruses, etc.  This information should be provided in the agent lists within each of the Protocol Activities.

The current standard of practice is that analgesics are to be given to animals following any survival surgery procedure.  You can contact the Veterinary Staff for assistance in choosing the correct analgesic and dose for your particular species and situation. You must provide scientific justification if you choose not to use an analgesic.  Please note, past history alone is not acceptable.

It is good practice to add a sentence that indicates if post-surgical pain is recognized you will consult with a clinical veterinarian to discuss disposition or treatment of the animal. In some cases euthanasia may be appropriate; in others, additional analgesics/antibiotics may allow you to keep the animal in the study.

Adverse Effects/Early Removal Criteria
Early removal criteria are designed to recognize pain and distress in animals. They are particularly important to correctly identify moribund animals that can be euthanized and spared from suffering. Be specific and focus on the most meaningful criteria. It is your animal model and you have to inform the Committee about the parameters you will measure.Be sure to relate criteria to specific aspects of your protocol.

In considering weight loss, be sure to indicate the time period over which the weight loss is evaluated and the reference point (e.g., weight at start of procedure, age matched litter mate, etc.).

Final Disposition
Any protocol group for which you list “euthanasia” as a final disposition will need to also be included in the upcoming Euthanasia question.

If you have listed a protocol activity as non-survival surgery or euthanasia, then this section will not be displayed as the information is provided in the protocol activity sections.

For confirmation of euthanasia, “absence of cardiac or respiratory function” is not acceptable for rodents.  A physical method must be indicated.

Animal Use Locations
Ensure that all protocol activities and protocol groups are listed in a use location.  If you have two “Agent Administration” activities, then both activities must be listed in the section.

Consideration of Alternatives to Painful or Distressful Procedures
The key words MUST include the (potentially) painful or distressful procedure(s).

The search narrative has to specifically address your findings in respect to the (potentially) painful or distressful procedure.Were any alternatives discussed? If so, how do they relate to your study? If this is the standard for this type of research, indicate this.

Justification for Number of Animals Requested
Make it EASY for the Committee to understand!

  • Explain reasons for group size (published results, statistical analysis based on previous established difference in measurements etc.). State which statistical tests are being applied (e.g., power analysis).  If you are using published results, include one or two references.
  • Clearly define the number of animals (e.g. 5 animals/group x 3 treatments x 4 time points x 2 different sexes = 120 animals). Define the groups, including controls, treatments, time points, etc.
  • When you have a complex protocol, in which the same animals or subsets of animals are used for multiple procedures, tables and/or flow charts can be useful to make things crystal clear to Committee members.
  • If you have a breeding protocol, in which many animals will not be used after genotyping, please make sure that the total number of animals produced and the total number actually used in the experiments/observations, can be clearly understood.  It is useful to start with the experiments to be carried out and then to work back to how many animals you will need to obtain through breeding.
  • When describing the number of offspring used, separate your numbers into those that will be used exclusively for breeding and those that will be used in experiments.
  • When you use euthanized animals for organ culture, provide rough estimate for the number of animals (e.g. we will get 3×107 cells per liver and need 6×107 cells per experiment, for 15 experiments that means 30 animals).

Funding/Sponsor Information
If you select that you do have funding, be prepared to attach the “animal procedure” section of your grant application (e.g. For NIH funding, the IACUC is looking for the Animal Vertebrate section of the grant and any section describing the in vivo work with animals).  The full grant does not necessarily need to be uploaded.

External Collaboration
See the IACUC SOP “Collaborations with External Entities” or contact the IACUC office for guidance on what additional documents might be required.

Study Team Requirements
Everyone handling animals for the purpose of animal research must be listed on an IACUC protocol.  Be sure to indicate the specific activity each member of the team will perform on the AUP. To be on a protocol, there are several items that need to be completed. To save time and decrease the chance of the protocol being delayed in review, the IACUC encourages people to complete the following requirements as soon as possible:

  • Registering to eProtocol – In order to move your information into the new online system, you must register into the eProtocol system. This can be done by going to and following the prompts to register.
  • Animal Training – This can be done online at under the tab “Animal Care and Use.” This course will be considered complete once the exam is taken at the bottom of the training module and an 80% or higher is achieved.
  • Occupational Health and Safety Training – This can be done online at under the tab “Occupational Health and Safety.” This course will be considered complete once the exam is taken at the bottom of the training module and an 80% or higher is achieved.
  • Registry into the Occupational Health Program – This can be done online at This requirement will be considered complete when the registry questionnaire is completed and the submit button is pressed at the bottom of the website.
  • Conflict of Interest (COI) Screening/Disclosure form –This can be done online at  This requirement will be considered complete when the questionnaire is fully completed and the submit button is pressed.  Please note that sometimes when the submit button is pressed, your questionnaire will re-appear with sections highlighted in yellow/orange.  Please complete these highlighted sections and hit the submit button again as your questionnaire will not be considered complete until the highlighted items are completed.
  • Your Experience and Training Narrative – This can be done online at under the tab “Your Experience and Training Narrative.” This will be considered complete when you write a brief narrative in the text box provided and hit the save button.

Part 2: Answering Questions During Review

When you are finished creating your protocol, you will then forward the protocol through the veterinary consultation and IACUC review processes.  Please find below a few tips on how to answer questions from the consulting or reviewing body:

Tip 1:  When the veterinary consultation and IACUC review are complete, your protocol may be sent back to you if there are questions or suggestions.  When this happens, the eProtocol system will send a notification to you via e-mail.  Use the link (which will be the protocol number) in the e-mail to go directly to your protocol’s home page.

Tip 2:  To find the questions, you must go into the actual protocol form (i.e. you need to hit the “Edit Protocol” button and find the questions in the protocol form).

Tip 3:  When responding to comments from the Veterinarians or the IACUC, be sure that you make the changes in the body of the document, not just in the reply box.  The dialog between PI and Vet/IACUC staff disappears after the protocol is approved and these responses will not be included in the document.
