固始鸡与青胫黄麻羽鸡杂交利用研究

Study on the Crossbred Hybridization of Gushi Chicken and Indigotic-crura Yellow-feather Chicken

[目的]充分利用地方品种固始鸡种质资源,通过杂交配套提高其生产性能。[方法]以固始鸡G系母鸡为母本,以固始鸡G系、快大青胫黄麻羽S1系、广西瑶鸡Y系等公鸡为父本,分别进行杂交组合,杂交后代分别为GG、S1G和YG。通过对杂交后代生产性能、屠宰性能及肉质性状进行测定,评价固始鸡的杂交利用效果。[结果]以S1系为父本、以固始鸡为母本的杂交配套组合,可有效提高固始鸡的生产性能和出肉率,提高肌内脂肪含量,从而改善固始鸡的肉品质。[结论]研究结果可为固始鸡种质资源特性的研究及保护利用提供参考。

[Objective] To take full advantage of excellent local germplasm resources of Gushi Chicken and improve the production performances by crossbred hybridization.[Method] Taking G line hen of Gushi Chicken as maternal parent,taking cock of Gushi Chicken G line,fast indigoticcrura yellow-feather chicken S1 line,Guangxi Yao chicken as male parent,the crossbred hybridization was made and crossbred combinations（ GG,S1 G,YG） were obtained.The production performance,slaughter performance and meat quality of crossbred offsprings were determined and the crossbred hybridization effect was evaluated.[Result]Crossbred combination with S1 line as as male parent,Gushi Chicken as maternal parent could effectively increase the production performance and meat rate of Gushi Chicken,increase the intramuscular fat content,so as to improve the meat quality of Gushi Chicken.[Conclusion]The research could provide references for the research,protection and utilization of Gushi Chicken germplasm characteristics.
