Effects of Compound Probiotics on Growth Performance, Serum Biochemical and Immune Indices and Volatile Fatty Acid Contents in Feces of Weaned Piglets
摘要
Abstract
This experiment was conducted to investigate the effects of compound probiotics on growth perform-ance, serum biochemical and immune indices and volatile fatty acid contents in feces of weaned piglets.Two hundred and forty weaned piglets (half male and half female) with (10.0±0.3) kg were randomly arranged in-to 4 groups with 6 replicates per group and 10 pigs per replicate.Pigs in groupⅠ( control group) were fed a basal diet ( contained 1% kitasamycin and 2% colistin) , and in groups Ⅱ,Ⅲ and Ⅳwere fed the basal diets supplemented with 50, 100 and 150 mL compound probiotics per day per piglet.The experiment lasted for 28 days after 5 days per-experiment.At the first day and the 28th day, the serum samples were collected through precaval vein to measure biochemical immune indices and the rectum content was collected to determine the contents of volatile fatty acids in feces.The results showed as follows: 1) compared with the control group, the average daily gain of weaned piglets was significantly increased by 23.53%( P<0.05) , the ratio of feed to gain was significantly decreased by 15.86%( P<0.05) , and the diarrhea rate was decreased by 47.16%( P>0.05).2) On the 1st day of the experiment, the serum biochemical and immune indices had no significant difference in all groups ( P>0.05 ) , and the volatile fatty acid contents in feces of piglets in experimental groups were higher than that in control group.3) On the 28th day of the experiment, the activities of alkaline phosphatase and aspartate aminotransferase and the contents of glucose, total protein, albumin and globulin in serum of piglets in group Ⅱ were higher than that in control group ( P>0.05) , while the urea nitrogen content in group Ⅱ was decreased by 18.27% compared with the control group ( P>0.05) .Compared with the control group, the contents of acetic acid, butyric acid and propionic acid in feces of piglets in group Ⅱ were in-creased by 21.03%( P>0.05) , 41.08%( P>0.05) and 77.84%( P<0.05) , respectively.It can be seen that dietary 50 mL probiotic every day per piglet can improve the growth performance of weaned piglets, reduce the diarrhea rate of piglets, enhance the immune function and increase the contents of volatile fatty acids in feces.关键词
