Abstract:

The distributional characteristics of VIP in different ages bursa of Fabricious of Chinese yellow feather quails were observed by using the immunohistochemical SABC method and microscopic image analysis.The result showed that VIP widely exists at newborn,1,3,5,9,13,17,21,23,25,32,36-week-old of Chinese yellow feather quail bursa,formed a long fusiform,horseshoe-shaped,oval,lumps or fine granular,mainly distributed in the submucosa,muscularis,serosa,and the distribution is the most typical at 3 weeks of age.To 25 weeks of age,the average optical density of VIP positive reaction reached the maximum,then gradually weakened.The result proves that VIP exists at all stage of growth in Chinese yellow feather quails bursa,and with the development and function of changes in bursal characteristics showing a certain correlation.
