Effect Of_Saccharicterpenin On Growth Performance And Defensive System In Broilers

Saccharicterpenin is a new feed additives,which developed jointly by Zhejiang University and Hangzhou TANG Technology Co., Ltd and owned the China's first intellectual property rights,its core technology has been in China, the United States, Europe and Japan patents in 18 countries. Water-soluble Saccharicterpenin is saccharicterpenin series of new products, and the function of water-soluble Saccharicterpenin in the growth performance of the defense system of broilers is still blank. This article will explore the different concentrations of water-soluble saccharicterpenin on growth performance and defensive system in broilers.540 broilers a day-old Ross 308 were randomly divided into six groups,30 broilers each three replicates, set the control group and the water-soluble saccharicterpenin group (50mg/kg, 100mg/kg,150mg/kg,200mg/kg,400mg/kg).42d after the feeding experiment to evaluate water-soluble saccharicterpenin impact on growth performance; determination of water-soluble saccharicterpenin on intestinal flora, intestinal morphology, and duodenal defense protein; and hormone and antibody levels of serum. From the balance of intestinal flora, intestinal defensive protein and structural integrity of the defense and hormone levels and antibody levels in serum to discuss the three defense barriers on the role of broiler defense system.1. water-soluble saccharicterpenin significantly increased daily gain of broilers. Add the water-soluble saccharicterpenin 200mg/kg group were significantly (P<0.01) daily gain, compared with the control group. Use of food/gram, the weighted average daily gain and survival rate integrated value derived from biological comprehensive evaluation shows that adding water-soluble saccharicterpenin improve growth performance,200mg/kg group of water-soluble saccharicterpenin comprehensive evaluation value of the biological the highest 1.1007.2. Water-soluble saccharicterpenin promote the development of the duodenum, increase intestinal villus height, reduce the crypt depth. The results show that 200mg/kg Saccharicterpenin-soluble saccharicterpenin was significantly (P<0.05) increased duodenal villus height and was significantly (P<0.05) increased villus height /crypt depth ratio; Water-soluble saccharicterpenin group increased intestinal villi height, decreased crypt depth, increased villus height and crypt depth ratio of jejunum, but the differences were not significant.3. Water-soluble saccharicterpenin promote the growth of beneficial bacteria and inhibit the growth of harmful bacteria in the cecum and ileum.200mg/kg Water-soluble saccharicterpenin group compared with the control group were significantly (P<0.05) lower broiler cecal E. coli and the number of Salmonella; Water-soluble saccharicterpenin have a certain role in increaseing the number of lactic acid bacteria.400mg/kg Water-soluble saccharicterpenin group compared with the control group can be very significant (P<0.01) increase the number of intestinal bacteria of lactic acid; In the broiler ileum,200mg/kg water-soluble saccharicterpenin group compared with the control group reduce some certain the number of E. coli, the effect on the Lactobacillus and Bifidobacterium are promoting growth, but the difference was not significant.4. Water-soluble saccharicterpenin can significantly promote the content of defense protein in chicken duodenum.200mg/kg and 400mg/kg Water-soluble saccharicterpenin group compared with the control group were significantly (P<0.01) increased duodenal SIgA levels; 400mg/kg water-soluble saccharicterpenin group compared with the control group can significantly improve the content of duodenal defensin 180.90%(P＜0.05),200mg/kg water-soluble saccharicterpenin group compared with the control group can improve the duodenum defensin content of 153.78%(P> 0.05).5. Water-soluble saccharicterpenin can regulate the somatostatin in serum. 400mg/kg Water-soluble saccharicterpenin compared with the control group were significantly (P＜0.01) decreased somatostatin levels in serum; 200mg/kg Water-soluble saccharicterpenin compared with the control group were (P>0.05) decreased somatostatin levels in serum;.
