Abstract

The aim of this study was to determine the effect of lactation length and litter size on the milk composition of Boer goats. Milk samples from 23 lactating Boer goats reared in NLBO (National Livestock Breeding Office), Pokhara, Nepal, were collected and analyzed in a laboratory present within a farm. Goats were reared under the same environment and provided with similar care and management. Lactation length showed a non-significant effect on fat content in the milk whereas all other constituents were influenced significantly. Similarly, litter size showed a significant effect on the freezing point of milk only. Litter size and all milk constituents were negatively correlated. However, Litter size and freezing point showed moderately strong correlation. Twinning did not significant influence fat, protein, lactose and solids nonfat content of goat milk. All constituents were weakly correlated to litter size however freezing point showed moderately strong correlation. Thus, more focus must be given to the nutritional management of triplets and twins to improve their growth rate compared to a single kid. © 2021, Online Journal of Animal and Feed Research.
