中文摘要：为了明确罗斯308肉鸡的生长发育规律,用Logistic、Gompertz和Von Bertalanffy 3种生长模型对120只罗斯308肉鸡进行生长拟合分析,并对不同周龄的平均周增重、相对增长率以及料重比进行测定。结果表明,Logistic、Gompertz和Von Bertalanffy 3种模型的拟合度均高于0.99;从拐点体重、拐点周龄等指标分析,Logistic曲线的拟合值与实际测定值最为吻合,拟合度、拐点体重、拐点周龄分别为0.99、2 160.25 g、5.77周;罗斯308肉鸡料重比在前后两期均为先高后低,6周龄料重比为后期最低。综合分析,Logistic曲线对罗斯308肉鸡生长拟合度最高,罗斯308肉鸡最佳出栏时间为6周龄。

外文摘要：In order to determine the growth and development rules of Ross 308 broiler, three growth patterns including Logistic, Gompertz and Von Bertalanffy were used to fit and analyze the growth of 120 Ross 308 broilers, and the different age average week gain, relative growth rate and feed conversion ratio were measured. The results showed that the fitting degrees of three models were all above 0.99. Analyzed from the indexes like inflection point weight and inflection point age, the fitted value of Logistic curve agreed with the actual measured value most, of which the fitting degree, inflection point weight and inflection point age were 0.99, 2 160.25 g and 5.77 weeks, respectively. The feed conversion ratios were from high to low in the two periods, and the lowest appeared in the later period. Comprehensive analyzed, Logistic curve most fit for Ross 308 broiler, and the best slaughter time was 6 weeks.
