Effect of genotype on milk yield and composition of crossbred goats
DOI: 10.1590/S1516-35982005000400034
The objective of this trial was to study the production of thirty-five crossbred goats: 1/2Brown Alpine x 12 1/2Moxoto (1/2BA-M), 11 3/4Brown Alpine x 1/4Moxoto (3/4BA-M), and 12 Tricross (1/2Anglo Nubian x 1/4Moxoto x 1/4Brown Alpine). After birth, the kids were separated from their mothers. Goats were milked twice a day and milk composition determined weekly. Animals were housed in collective pens and received a diet composed of sorghum silage (ad libitum) plus concentrate that were formulated to allow 2.5 kg/d of milk yield. Animals were weighted every 14 days. Milk production did not differ among genotypes. However, 4% fat corrected milk was greater for 1/2BA-M than the remaining groups. No significant differences were observed for milk composition (fat, protein, and total solids) across genotypes in the current trial.
