Abstract:200 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.
