Effects of supplementation and milking of Matebele does four weeks pre-partum to weaning, on milk yield, kid birth weight and growth rate were studied. Forty does were divided into four treatments: supplemented and milked (SM), supplemented and not milked (SNM), not supplemented and milked (NSM); and not supplemented and not milked (NSNM). Supplemented goats were given 200 g/doe/day of Dichrostachys cinerea pods containing 19% CP. The study was carried out in September during time of feed unavailability and animals were grazed on rangelands for seven hours before being given the supplement. Fifty-six kids were born from all the experimental animals and 24 were singles whereas 32 were twins. Milk yield was higher (P<0.05) in supplemented than non-supplemented does. Although supplementation had no effect on kid birth weights, growth rates were higher (P<0.05) in the SNM group (103±10.1 g/day) than in the SM group (74±10.8 g/day). Among the non-supplemented groups, kids from milked does had higher (P<0.05) daily gains (85±10.9 g/day) than those from non-milked does (67±10.7 g/day). Weaning weights were higher (P<0.05) in SNM does (12.8±1.30 g/day) than in the SM does (10.2±1.17 g/day). Among kids from the non-supplemented does, those from milked does had superior (P<0.05) weaning weights (11.2±1.23 g/day) than those from non - milked does (9.2±1.27 g/day). Mortalities were also lowest in kids born from SNM does. It is concluded that pre-partum to weaning supplementation generally increases milk production which then increases kids growth rates and weaning weights, as well as reduce kid mortalities. © 2008 Springer Science+Business Media B.V.
