The effect of dietary protein supplementation on reproductive performance of Tswana/boar goats was studied. Twenty-four female Tswana/ boar goats with similar body weight and age (3 months old and 10.56±1.28 kg body weight) were randomly allocated into three treatment groups: Treatment 1, 2 and 3 (8 goats per treatment) in a completely randomised design. The goats were supplemented with 23.51 g protein and 8.55 g energy per kg incremental. Live body weight was recorded every 14 days.The results show gain of body weights from week 1 to 32 with significant difference (P<0.05) between the three treatments. Treatment group 1 showed high body weight gain (9.46±0.5 kg), followed by Treatment 2 (8.36±0.6 kg) and Treatment 3 (7.79±0.5 kg), respectively, from week 20 to week 36. Feeding of goats with high protein treatment significantly (P<0.01) increased protein intake (3X maintenance vs 1X maintenance) compared to low protein treatment. These results indicate that, increasing levels of supplemental protein improved live weight gain and reproductive performance of female goats. Therefore, supplementation of higher level of dietary protein (11.98 MJ ME/kg dry matter) may be suggested for optimizing growth and reproductive performance of female goats under grazing conditions, good health and good reproduction.
