crossbreed goats (LLG x WADG). They were managed under semi-intensive system. The animals were fed with concentrates at 200-300g per goat per day and allowed to browse on the University paddock in the afternoon. Live body weights were recorded weekly from birth to 12 – month of age. Heritability estimates at birth and 12-month live body weight were analysed. The results indicate that genotypes and parity had significant effect on litter size of does (P< 0.05). Different rearing seasons also had significant influence on birth and 12- month body weights (P< 0.05). The body weight was of medium to high heritability. Significant phenotypic correlation existed between litter size, birth and 12-month body weight but recorded negative genetic correlation (P<0.05). The birth and 12-months genetic and phenotypic correlation were significant (P<0.05). It was concluded that Nigerian crossbred goat (LLG x RSG) could be selected at birth and 12-months age for heritability improvement programme and could be best be raised in April through September when Nigerian pastures are at its optimal or nutrient peak.
