Observation on the Breeding Effect of Macheng Black Goats
摘要
Abstract
[Objective] The study aimed to enhance the production performance of Macheng black goats.[Method] The hybrid progenies were produced from a hybridization of male black goats with big ears from Jianyang of Sichuan and female Macheng black goats.The breeding cultivation system consisted of 1 core breeding field and a few breeding fields was established during their intersex breeding.The production performance indices of selected Macheng black goats were observed in 2006.[Result] Compared with initial Macheng black goats, the average body weights of selected primary, 3 months old and 12 months old male and female Macheng black goats were enhanced by 6.29%, 7.78%, 9.57% and 5.71%, 9.23%, 8.97% resp.;their body sizes also had som increment;their lambing was very outstanding, the proportion of female goats produced more than two lambs was up to 82.30% and their average annual lambing rate was up to 346%.The slaughter rate, net meat percentage and meat-bone ratio of selected 12 months old Macheng black goats were 51.4%, 34.8% and 3.88.Compared with initial goats, their slaughter rate was enhanced significantly (P<0.05) and their propagation performances were improved, too.[Conclusion] All the production performances of selected Macheng black goats were enhanced and the breeding effect was significant.关键词
