Preliminary assessment of Boer and Kiko does as maternal lines for kid performance under humid, subtropical conditions

摘要: Thirty Boer and 27 Kiko does were exposed to Spanish bucks evaluated for doe reproduction, pre-weaning kid growth, production efficiency in the humid, subtropical south-eastern United States. Does of each breed represented by at least seven seed stock farms eight sires. Twenty-five 23 gave birth one live kid. Body weights parturition heavier than dams. Litter size litter weight similar (1.92 ± 0.12 kids, 6.05 0.31 kg) dams (1.82 5.90 0.33 kg). Birth between 46 42 F1 kids. single twin kids; kids triplet Bucks birth.
