Abstract
Objective:The experiment was conducted with healthy broilers to study the effect of cysteamine on the immmuno competence of broilers.And the mechanism were discussed.Method:The seven-day-old broiler was divided into four groups randomly,And 0mg/kg,50mg/kg,100mg/kg,150mg/kg CSH was added to each group.Result:The activity of lysozyme、bursal index and spleen index was increased significantly with CSH adding to broilers(P0.01);and it was significantly different between the experimental group Ⅱ,Ⅲ compared with the control group significantly;Serum immunoglobulin globulin IgA levels and serum IgM levels was increased significantly with the CSH adding(P0.01);The T,B lymphocyte transformation rate was increased significantly with CSH(P0.01).Adding CSH raised the immunecompence level of broiers significantly.Therefore the effect of test group Ⅱ was the most obviously on imummocompence indicators.
