Effects of trypanosome infection and postpartum liveweight change on resumption of reproductive activity in N'Dama cows
A total of 4355 lamb and 4299 ewe records, obtained from Sabi sheep of Zimbabwe from 1984 to 1994, were analysed to describe growth, carcass and reproductive traits and to investigate non-genetic factors influencing their expression. Year of birth, sex, birth/rearing status of lamb, dam age, age ...
