Inclusion of some plants especially spices in the diets of farm animals have been researched upon extensively for parameters like growth, blood chemistry, and feed utilization among others. In contrary, the use of turmeric as feed additive for ruminant production is so low, while its effects on reproduction (especially during pregnancy) in ruminants are not available due to little/no information on its properties, processing, and inclusion rate. Thus, a study was conducted to evaluate pre- and post-weaning performances of kids produced by three breeds of goat fed diets supplemented with graded levels of turmeric powder intensively in southwestern Nigeria. Kids produced by Kalahari Red (KR), West African Dwarf (WAD), and KalaWAD Does fed diets containing turmeric powder (TP) at different levels were monitored for pre-weaning that lasted for 12 weeks, while selected kids were observed for 4 weeks post-weaning. Each Doe breed was fed diet at 5% bodyweight during pregnancy and pre-weaning, including some selected kids during post-weaning. Dietary treatments included concentrate diet (CD) as TP-0, CD + 2 g/kg TP as TP-2g, and CD + 5 g/kg TP as TP-5 g. Brachiaria ruziziensis was used as basal diet. Data obtained were arranged in a 3 × 3 factorial layout in a completely randomized design, while analysis of variance was done using SAS 9.1. Significance level was taken at 5% probability, while means were separated using Duncan’s multiple range test of the same statistical package. Results of the study for breed effect revealed that KR kids had the best ( p < 0.05) pre-weaning performance from birth (3.2 kg) till weaning (14.5 kg) and for weight gains (11.2 kg and 134.0 g/day). No mortality was recorded for WAD kids. For TP effects, the kids fed TP-2g had the highest ( p < 0.05) weight gains (1.6 kg and 58.6 g/day) and reduced value for feed conversion ratio (FCR) of 6.2 for post-weaning performance. Kids fed TP-5g had the highest ( p < 0.05) value for protein efficiency ratio (PER) of 1.4 at the end of post-weaning. For interaction effects of breeds and TP, KR kids fed TP-5g performed best ( p < 0.05) at the pre-weaning period in terms of weights from birth (3.6 kg) till weaning (15.7 kg), while KR kids fed TP-2g had highest ( p < 0.05) pre-weaning weight gains (12.5 kg and 148.9 g/day). KR kids fed TP-5g performed best ( p < 0.05) at the post-weaning period in terms of weight gains (1.8 kg and 64.4 g/day). KR kids fed TP-2g and KalaWAD kids fed TP-5g had the lowest FCR (5.2) and the highest PER (1.6) respectively at the post-weaning period. It can be concluded that breeds of kid, TP inclusion, and their interaction influenced pre- and post-weaning performances of the kids.
