The U-M has established a practice for counting animals produced that minimizes opportunity for pain and distress up to the day of weaning. The practice also accounts for not only those animals needed for research, but also those which do not meet identified criteria (e.g., genotype) established for the specific study proposal. Consequently, animals produced through in-house breeding are counted according to the following practice:
- Rodents (not regulated by the USDA) produced through in-house breeding are counted at weaning. Animals who are euthanized or culled prior to weaning are reported via the ULAM breeding sheets.
- Larval fish are counted at 7 days post-fertilization and are reported on the Non-Traditional Animal Acquisition Form within eRAM.
- All other species are counted upon birth, shortly following hatching, or at first manipulation as is appropriate to the species, and are reported on the Non-Traditional Animal Acquisition Form within eRAM.
- Animals used for research, teaching, testing, or demonstration at any time points earlier than those noted above should be counted at time of use and are reported on the Non-Traditional Animal Acquisition Form within eRAM.
 Manipulation is defined as any activity/procedure including for example, euthanasia, genotyping, and/or methods used for identification conducted on an animal.
