| 摘要：本研究为大陆生长速度较慢、肉质优良的地方鸡种的开发利用中，寻找生长速度快、且肉质优的杂交组合，首次将萨索鸡与不同地方品种（白羽肉鸡、涟水土鸡、海兰蛋鸡）进行杂交，12周龄前每隔2周对三种杂交后代（萨白肉杂鸡、萨涟土杂鸡、萨海蛋杂鸡）各12只进行生长屠宰性能指标的测定，并进行简单的相关分析。结果表明：萨白肉杂鸡的生长速度和屠宰率显著高于其他2个杂交组合；萨涟土杂鸡的生长速度快于涟水土鸡，屠宰率差异不显著；萨兰蛋杂鸡的生长速度慢于817杂交鸡，屠宰率低于817杂交鸡。结合以上指标，萨白肉杂鸡和萨涟蛋杂鸡的生长屠宰性能优良，萨兰蛋杂鸡不利于杂交利用。26570 毕业论文关键词：萨索鸡；杂交；生长发育性能；屠宰性能 Analysis of Growth Slaughter Performance of Different Hybrid Offspring of Sasso. Abstract：In this study, in order to filter the hybridized combination with high growth rate and excellent meat quality of local chicken breeds with slow growth and good meat quality. For the first time, the Sassau chicken was hybridizated with different local breeds (Baiyu broiler, Lianshui chicken, Hailan layer). Every two weeks before 12 weeks of age, three hybrid offspring(Sasso-Baiyu hybeid chicken, Sasso-Lianshui hybeid chicken，Sasso-Hailan hybeid chicken) were used to determine the growth slaughter performance of 12 inpiduals, and a simple correlation analysis was carried out. The results showed that the growth rate and the slaughter rate of Sasso-Baiyu hybeid chicken were higher than those of the other two hybridized combination ; the growth rate of Sasso-Lianshui hybeid chicken is higher than that of Lianshui chicken , the slaughter rate was not significant;the growth rate of Sasso-Hailan hybeid chicken is slower than 817hybeid chicken,the slaughter rate is lower than 817hybeid chicken. Combining with the above indexes, the growth and slaughter performance of Sasso-Baiyu hybeid chicken and Sasso-Lianshui hybeid chicken is fine. Sasso-Hailan hybeid chicken is not conducive to cross-use.
