Growth performance by Alpine, Angora, Boer and Spanish wether goats consuming 50 or 75% concentrate diets

Forty-five weaned wether goats (12 Alpine, 12 Angora, 10 Boer (87.5%) and 11 Spanish) were used to determine effects on growth performance of consumption of a 75% concentrate diet (DM basis) for 24 weeks (75C) or for 12 weeks subsequent to 12 weeks of feeding a 50% concentrate diet (50C). Initial BW...

Description
Summary:Forty-five weaned wether goats (12 Alpine, 12 Angora, 10 Boer (87.5%) and 11 Spanish) were used to determine effects on growth performance of consumption of a 75% concentrate diet (DM basis) for 24 weeks (75C) or for 12 weeks subsequent to 12 weeks of feeding a 50% concentrate diet (50C). Initial BW was 20.2, 12.2, 20.7 and 19.2 kg (S.E.=0.73) for Alpine, Angora, Boer and Spanish, respectively, and age was 4 months when the experiment began. There were no interactions between genotype and dietary treatment in DM intake, ADG or gain efficiency in weeks 1–12 or 13–24. DM intake in weeks 1–12 ranked Alpine and Boer>Spanish>Angora (703, 689, 567 and 436 g per day; P
