The objective of this trial was to study the production of thirty-five crossbred goats: ½Brown Alpine x 12 ½Moxoto (½BA-M), 11 ¾Brown Alpine x ¼Moxoto (¾BA-M), and 12 Tricross (½Anglo Nubian x ¼Moxoto x ¼Brown 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 ½BA-M than the remaining groups. No significant differences were observed for milk composition (fat, protein, and total solids) across genotypes in the current trial.
