摘    要:选艾维茵肉鸡商品雏200只,按常规饲养管理,于初生和1~7周龄的周末,分性别各解剖8只,测量消化器官重量及消化道各部分长度,并进行与体重变化的回归分析。结果:消化器官重量及消化道各部分的长度随体重同步变化,约在4周龄时消化器官重超过饲养阶段的平均数。消化器官重量及消化道长度与体重变化的幂回归的相关系数最高。

关 键 词:肉鸡  消化器官  回归分析

Abstract:Avaines broilers were fed conventionally and used to study growth regularities of digestive organs.They were divided into two groups,male and female,n=8 in each group,and dissected at birth and 1-7 weeks old respectively.The weights of the digestive organs and lengths of every part of the digestive tract were measured.In addition,regression coefficients between them and the changes of the body weights were analysed.The results showed:That the changes of weights of the digestive organs and the lengths of the digestive tracts were coincide with that of the body weights.The weights of the digestive organs at 4 weeks old were over the average of the feeding stage.Correlation coefficients of logarithmic regressions between the weight of digestive organs,the lengths of the digestive tracts and the growth of the body weights were the highest.
Keywords:brioler    digestive organs    regression analysis
