Effects of Yeast Culture, Bacillus subtilis and Papain on Growth Performance, Nutrient Apparent Digestibility and Fecal Microflora Number of Nursery Piglets
摘要
Abstract
For investigating the effect of Saccharomyces cerevisiae separated from massa medicata fermentata and sourdough, we studied the effects of newly developed composited yeast culture ( YC) , Bacillus subtilis ( BSK) and papain ( PE) on growth performance, nutrient apparent digestibility and fecal microflora number of nursery piglets. A total of 225 weaner piglets with initial body weight of (15.70±0.26) kg were randomly allotted to 5 groups with 3 replicates per group and 15 piglets per replicate. The control ( CT) group fed a basal diet, the YC groups fed the basal diet supplemented with 5 g/kg YC, the BSK group fed the basal diet supple⁃mented with 2×1011 CFU/kg BSK, the PE group fed the basal diet supplemented with 0.3 g/kg PE, and the complex ( YP) group fed the basal diet supplemented with 5 g/kg YC and 0.3 g/kg YP. The pretest period and test period lasted for 5 and 30 days, respectively. The results showed as follows:1) the final weight and aver⁃age daily gain ( ADG) of YP group were significantly higher than those of CT group ( P<0.05) , the feed to gain ratio (F/G) of YP group was significantly lower than that of CT group (P<0.05). The final weight of YC group was higher than that of CT, BSK and PE groups ( P>0.05) . There was no significant difference in average daily feed intake ( ADFI) among all groups ( P>0.05) . The diarrhea rate of YC, PE and YP groups was significantly lower than that of CT and BSK groups ( P<0.05) . 2) The apparent digestibilities of gross en⁃ergy ( GE) and dry matter ( DM) of YC, BSK, PE and YP groups were significantly higher than those of CT group (P<0.05), the apparent digestibilities of crude protein (CP) and phosphorus (P) of YC group were significantly lower than those of YP group (P<0.05), the apparent digestibilities of neutral detergent fiber ( NDF) and calcium ( Ca) of YC group were significantly lower than those of other groups ( P<0.05) . There were no significant difference in the apparent digestibilities of organic matter ( OM) and ether extract ( EE) a⁃mong all groups (P>0.05). 3) The fecal Escherichia coli number and Lactobacillus/Escherichia coli of YC and YP groups were significantly higher than those of other groups ( P<0.05) , and the fecal Escherichia coli number was significantly lower than that of other groups (P<0.05). In conclusion, the newly developed YC can improve the growth performance and intestinal micro⁃ecology environment of the piglets. The YC and PE combination can also improve the growth performance.关键词
