【摘要】：本试验对庄河大骨鸡及其杂交鸡外形、生长性能和屠宰性能进行研究。结果表明:青脚大骨鸡公鸡体重显著大于黄脚大骨鸡公鸡(P005),黄脚大骨鸡屠宰率大于青脚大骨鸡屠宰率(P005)。大骨鸡与肉种鸡正反交所得公鸡屠宰率差异显著(P005),母鸡差异不显著(P005);大骨鸡与蛋种鸡正反交所得公鸡屠宰率差异不显著(P005),母鸡差异显著(P005)。大骨鸡与肉种鸡杂交后代体重与大骨鸡相当,杂交鸡在整个生长周期内的体重都是平稳的增长。结论,青脚大骨鸡比黄脚大骨鸡屠宰性能更高;大骨鸡做为母本产生的后代具有更高的屠宰性能,大骨鸡与肉种鸡的杂交后代屠宰性能高于大骨鸡与蛋种鸡杂交后代。
[Abstract]:The appearance, growth performance and slaughter performance of Zhuanghe Dagu Chicken and its crossbred chickens were studied. The results showed that the weight of the big bone chicken was significantly higher than that of the yellow foot big bone cock, and the slaughter rate of the yellow foot big bone chicken was higher than that of the green foot big bone chicken. There was significant difference in slaughter rate between big bone chicken and broiler crossbred cock (P005), but no significant difference in hen (P005), but there was no significant difference in slaughter rate between big bone chicken and egg breeding chicken (P005) and significant difference between hen and hen (P005). The body weight of crossbred offspring of big bone chicken and broiler was the same as that of big bone chicken, and the weight of hybrid chicken increased steadily in the whole growth cycle. Conclusion: the slaughter performance of big bone chicken with green foot is higher than that of big bone chicken with yellow foot, and the slaughtering performance of cross progeny of big bone chicken and broiler is higher than that of big bone chicken and egg broiler.
