125 Shaoxing Ducks at the age of 60 days are used to estimate the phenotypic correlations between contents of IGF-I. contents of TP, activity of GOT, activity of GPT and the three laying traits(total eggs of 300 days, total egg weight of 300 days, the average egg weight) respectively. Treating the three laying traits as dependent variables, proceed path analysis in trail correlation of 60 days. The goal of this article is to offer science evidence for the preselecting Shaoxing Duck. The analytical result of the relationships indicate that the blood GPT has middle correlations with total eggs of 300 days(0.5274), total egg weight of 300 days(0.6234), strong correlations with the average egg weight (0.6395). The correlation coefficients are highly significant(P 0.01). TP has weak correlation with the correlation coefficients are the three laying traits (0.2067, 0.2629, 0.3026). However, the correlation coefficients are all significant(P 0.05). The results of path analysis show : GPT has great positive directs on the three laying traits (0.5275, 0.6109. 0.6395).
