This study was conducted under natural range conditions at a semi-arid region of Sudan (Abu Deleig), during 1998 B 2000. One hundred and eighteen Sudanese Nubian kids, of both sexes were allowed to suckle freely colostrum for the first three days following parturition. Thereafter, they were allowed to suckle all the morning milk and half of the evening milk, for three months and then weaned. The incidence of death among the kids, were closely monitored and related to a number of factors: including type of birth, sex of kid, birth weight, dam parity order, season of kidding and age of kid. The results revealed that the abortion, pre-weaning and overall kid mortality rates were 21.2, 15.2 and 36.4%, respectively. Type of birth, sex of kid, birth weight of kid, parity order, season of kidding and age of the kid significantly affect kid mortality rates. The study indicated that, by instituting adequate management improvement action in addition to selection for larger kids at birth, the productivity of goat could be improved.
