摘要

In this Research Communication we report milk yield, milk composition and udder morphometry of Hair, Alpine × Hair F_1(AHF_1 and Saanen × Hair F_1 (SHF_1 cross-bred goat genotypes managed in a semi-intensive system. The SHF_1 genotype had significantly higher lactation milk yield, fat yield, protein yield, and electrical conductivity than other genotypes, whilst AHF_1 was intermediate The milk fat, protein, lactose, solids-non-fat and total solids contents as well as pH and density of the Hair goat milk were significantly higher than the corresponding values of the cross-bred genotypes. The highest correlation amongst udder characteristics and production was between lactation milk yield and udder volume (P＜ 0.01; r = from 0.63 to 0.77). The results of this study suggest that crossbreeding can have a positive effect on the milk production characteristics of local goats, thereby reducing the pressure on the ecosystem, and suggest that udder measurements, especially volume, can be a helpful tool for estimating milk yield.
