摘  要：
为了探讨家禽生长发育的规律性,选用大恒优质肉鸡第七世代的S06、S01、S05品系公母各50只,测定1~10周龄的体重,并用Logistic、Bertanlanffy、Gompertz模型对其进行生长曲线拟合。结果表明,3种模型都能很好地拟合大恒优质肉鸡体重的生长曲线(R2>0.99)。但综合分析表明,Gompertz曲线对S06♀(R2=0.9981)、S01♂(R2=0.9991)拟合最为合适。Bertanlanffy曲线对S06♂(R2=0.9987)、S01♀(R2=0.9996)、S05♂(R2=0.9996)和S05♀(R2=0.9995)拟合最合适。

摘  要：
In order to study the rule of early growth weight and development,300 Daheng quality broilers were collected from S06,S01 and S05 three strains,every strain including 50 females and 50 males.Their body weights were measured from the 1st to the 10th weekend and the regression of weight-weeks were fitted with Logistic,Bertalanffy,and Gompertz model.The results showed that the three models be fitted to Daheng quality broiler weighth curve(R2> 0.99) and the estimated value was a good indicator of Daheng broiler growth,but the further analysis showed that the Gompertz curve S06 ♀(R2 = 0.9981),S01 ♂(R2 = 0.9991) be fitted to a most appropriate,Bertalanffy curve S06 ♂(R2 = 0.9987),S01 ♀(R2 = 0.9996),S05 ♂(R2 = 0.9996),S05 ♀(R2 = 0.9995) be also fitted to the most appropriate.
