Section B RODENT BREEDING COLONY For rodents several variables to consider: 1) expected litter size for the strain; 2) Genotype of breeders will affect usable offspring; add an extra female or two as a buffer, etc. B1. List species to be bred, indicate the number of breeders and provide estimates for the numbers of offspring expected over a 3 year period. # of Breeders Species Male Female Expected # of Offspring B2: List the background stock/strain (e.g. C57BL/6, BALB/c, Sprague Dawley): B3. Describe the breeding/mating system that will be used. Total # of Animals (Breeders + offspring) Number of Animals Born, but not used on this AUF (include in table on pg. 4) B4. a. Identify the tissue collection site for genotyping: Distal Tail Distal End of Toe (tail tissue biopsy should be < 2mm; general anesthesia required after 28 days of age) (toe sampling should be performed within 5-7 days of age in mice) Ear Pinna (< 2mm punch) Hair/Fur (2 tufts; ~20 follicles) Fecal Pellet (~3-5 pellets) Buccal Swabs / Saliva (swab from inner cheeks at >3 days of age) b. Will you be following the CAR Guideline for genotyping and tissue collection? http://animalcare.msu.edu/guides (CAR4: Rodent Genotyping) Yes B5. If no, please justify and describe your technique: Will you be breeding genetically modified rodents that contain more than 50% of an exogenous eukaryotic virus? Yes B6. No No Will you be breeding genetically modified rodents whose transgene is under the control of a functional gamma retroviral (MLV, FIV, etc.) long terminal repeat. Yes June 2015 No Page 1
