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,
). 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.
