摘要
本研究统计了徐海鸡、贵妃鸡、北京油鸡、崇仁麻鸡及其杂交后代共10个鸡群18周龄的外貌特征;测定其0～18周龄体重,运用Gompertz模型拟合生长曲线,研究证实了有胫羽对无胫羽、5趾对4趾为显性,初步判断黄羽对麻羽为显性、秃鹫样跗关节对非秃鹫样跗关节为不完全显性。结果表明,徐海鸡羽色、秃鹫样跗关节等性状需进一步提纯,Gompertz模型能较好地拟合各种生长情况。
In this paper,the appearance traits of Xuhai,Princess, Beijing You,Chongren partridge chicken and their hybrids at 18 weeks of age were evaluated, and body weights from 0 to 18 weeks of age were measured. Gompertz model was used to fit their growth curves. The results showed that feathered shank and polydactyly were identified as dominant traits ; in this preliminary investigation, yellow （Ewh） were dominant feather color comparing with patridge; the incompletely penetrance of vulture hocks would require further study. Some traits in Xuhai chicken, including plumage color and vulture hocks, would require further purification. Gompertz was the best model to evaluate the growth of chickens in early age.
