Abstract:
By using routine H. E method and measuring the absolute weight and growth index of thymus and ANAE positive ratios, 1 to 49 days Tianfu duckling were selected to study the changing trends in the normal development of the thymus. The results are as follows:the thymus of duckling develops slowly from 1 to 14 days,and quickly from 21 to 35 days,then steadily from 35 to 49 days. By the 28th day,most T-lymphocytes have well differentiated and the thymus has reached its maturation. There are three types of thymie corpuscles whose functions have been discussed.
