Inbred Strains of Mice: ICFW


Inbr: F37. Albino. Genet: c. Strain developed from outbred CFW stock by Festing in 1965.


Sensitive to Warfarin (2/12) (Lush and Arnold, 1975). Short sleeping time under hexobarbital anaesthetic (2/15 in males, 5/15 in females) (Lovell, 1976), short sleeping time under pentobarbitone anaesthetic (2/23), Lovell (1986). Good reproductive performance (2/25), with colony output 1.5 young/female/wk and litter size at weaning high at 6.1(4/25) (Festing, 1976a). Probably only exists as frozen embryos.
