摘 要:五华三黄鸡是广东省特有的地方优良肉用家禽品种。为给五华三黄鸡的保种选育提供参考依据,于2011年5月至2012年5月对公母混养的60只五华三黄鸡进行饲喂试验,测定其体重、体尺、屠宰性能等指标。结果表明:五华三黄鸡生长发育比较缓慢,210日龄的鸡的平均体重为1 022.5 g,其体斜长和胫长较长,胸深较深;公鸡的屠宰率为88.71%,母鸡的屠宰率为92.63%;公鸡的全净膛率为63.14%,母鸡的全净膛率为60.93%;公鸡的腿肌率为23.67%,母鸡的腿肌率为19.61%;公鸡的腹脂率为0.58%,母鸡的腹脂率为0.63%;对屠宰性能进行邓肯检验的结果显示,公、母鸡的屠宰率差异有统计学意义(P<0.01),活重、半净膛率、全净膛率、腿肌率差异也有统计学意义(P<0.05),而其他各性状间的差异无统计学意义(P>0.05)。Wuhua three-yellow chicken is a famous indigenous chicken breed in Guangdong province. To provide reference data for Wuhua three-yellow chicken conservation and selective breeding, 60 Wuhua three-yellow chickens were feed in a male and female-mixed style. The body weight, body measurement and slaughter performance of the chickens were investigated. The result showed that three-yellow chicken was growing slowly, the average body weight of the 210 day-old chicken was 1 022.5 g, the body slanting length and shank length were long and the chest depth was deep The dressing percentage of cockerel chicken and female chicken were 88.7% and 92.63% respectively, the eviscerated percentage were 63.14% and 60.93% respectively, the leg muscle rate were 23.67% and 19.61% respectively, and the abdominal fat rate were 0.58% and 0.63% respectively. Statistical tests performed on slaughter performance indicated that between cockerel chicken and female chicken, the difference of dressing percentage was statistically significant (P〈0.01), body weight, semi-eviscerated percentage, eviscerated percentage and leg muscle rate were also statistically significant (P〈0.05), but no difference existed (P 〉 0.05) in other characters.
