复合菌制剂对断奶仔猪生长性能、粪便微生物和血清指标的影响
Effects of Complex-Probiotics on Growth Performance, Fecal Microbiota and Serum Profiles in Weaner Piglets
摘要
Abstract
This study was conducted to evaluate the effects of complex-probiotics supplementation on growth performance,fecal microbiota and serum profiles of weaner piglets.Ninety-six (48 females and 48 males)piglets (Large White × Landrace) weaned at 35 to 37 days of age [the average body weight was (9.70 ±0.88) kg] were selected and divided into 3 groups with 4 replicates per group and 8 piglets per replicate.The piglets in each group were fed one of 3 diets:a basal diet without antibiotics and probiotics (control),the basal diet supplemented with complex-probiotics (including Bacillus licheniforms,Bacillus subtilis and Lactobacillus plantarum,probiotics group) or the basal diet supplemented with kitasamycin (antibiotic group).The trial lasted for 35 days.The results showed as follows:1) during the whole experiment period,no differences among three groups in average daily feed intake (ADFI) and average daily gain (ADG) were detected (P >0.05).2) On day 35,the number of E.coli in feces of the piglets fed the diets supplemented with complexprobiotics was significantly lower than that fed the other diets (P < 0.05).3) On day 14,compared with the control group,the supplementation of complex-probiotics significantly increased serum albumin content (P <0.05),but significantly decreased the ratio of albumin to globulin in serum (P < 0.05).On day 35,compared with antibiotic group,serum globulin content of piglets fed the diets supplemented with complex-probiotics was significantly increased (P < 0.05) and the ratio of albumin to globulin in serum was significantly decreased (P < 0.05).During the whole experiment period,the contents of albumin,urea nitrogen and creatinine,and the activity of alkaline phosphatase in serum were unaffected by the supplementation of complex-probiotics (P > 0.05).4) On day 14,the supplementation of complex-probiotics significantly increased serum IgM content compared with the control group (P < 0.05).On day 35,the supplementation of complex-probiotics significantly increased serum IgA content compared with antibiotic group (P < 0.05).These results suggest that complex-probiotics supplementation of Bacillus licheniforms,Bacillus subtilis and Lactobacillus plantarum decreases the number of E.coli in feces and enhances immune responses in piglets.关键词
