Study on Effects of Compound Probiotics on GrowthPerformance and Immunity Levels for Suckling Piglets
摘要
Abstract
The study is to research effects of the compound probiotics made of Lactobacillus casei, Saccharomyces cerevisiae and Bacillus subtilis on the clinical application of suckling piglets.Forty suckling piglets were divided into control group and experimental group, then at the age of 7th,14th and 21th days old, blood samples were collected from the precava of the suckling piglets for detection of physiological and biochemical indexes of blood, at the 21th days old, one piglet was randomly selected from each group and was dissected, the small intestine was dealt with and detected intestinal mucosa of SIgA levels.The results showed that the compound probiotics can significantly improve average daily gain of suckling piglets(P<0.05), reduce diarrhea rate of suckling piglets(P<0.01), increase the number of white blood cells, lymphocytes red blood cells and blood platelet(P<0.05).The content of LDH, ALP and TP of experimental group were all extremely higher than the control group(P<0.01), the ALT, AST and serum BUN content were all significantly higher than the control (P>0.05).Furthermore, it also increased IL-6, IL-1β and TNF-a secretion (P<0.05), and enhanced the SIgA levels of duodenum and cecum mucosa (P<0.05) and jejunum secretion(P<0.01).The study suggested that the compound probiotics can improve the growth performance and immunity levels of suckling piglets.关键词
