摘要: Understanding fitness level among various breeds is essential for sustainable meat goat production. Research on the relative of Boer F1 does and straightbred base breed has been limited. Meat genotypes (Boer, Kiko, Spanish, × Kiko reciprocal crosses, Spanish crosses) were studied to evaluate effects doe traits expression heterosis over 7 production years. The herd was semi-intensively managed under humid subtropical pasture. Doe age affected (P 0.05) from breeding weight. body weights crosses did not differ > their respective cohorts at breeding, kidding, or weaning. had lower < kidding rate (KR) weaning (WR) than other crosses. similar KR WR. also However, combined group 0.01) WR purebred biotype does. weaned smaller litter sizes per exposed compared with latter four breedtypes differing each other. dams higher fecal egg counts parturition dams.
