Effects of Dietary Bacillus subtilis along with Different Manganese Levels on Growth Performance, Slaughter Performance, Antioxidant Activity and Serum Biochemical Indices of Wulong Geese Aged from 12 to 16 Weeks
摘要
Abstract
This study investigated the effects of Bacillus subtilis along with different levels of manganese on growth performance, slaughter performance, antioxidant activity and serum biochemical indices of Wulong geese aged from 12 to 16 weeks, and aimed to find a method of producing diet with low manganese supple⁃mental level. A total of 360 twelve⁃week⁃old Wulong geese were randomly divided into 6 groups of 6 replicates per group and 10 geese per replicate ( half male and half female) . The geese in group Ⅰ were fed a diet with an optimal supplemental level of manganese ( 105 mg/kg, Bacillus subtilis was not added) , whereas the geese in groups Ⅱ to Ⅵ were fed diets with 250 g/t Bacillus subtilis and supplemented with 0, 35, 70, 105 and 170 mg/kg manganese, respectively. The experiment lasted for 5 weeks. The results showed as follows: 1 ) the body weight and average daily gain in groups Ⅳ and Ⅴ were significantly higher than those in group Ⅰ(P<0.05), the ratio of feed to gain in group Ⅳ was significantly lower than that in group Ⅰ (P<0.05). 2) The dressed percentage, percentages of half⁃eviscerated yield, percentages of eviscerated yield and percentages of leg muscle in group Ⅳ were significantly higher than those in group Ⅰ ( P<0.05) , whereas the percentage of abdominal fat in groupsⅣ,ⅤandⅥwas significantly lower than that in groupⅠ( P<0.05) . 3) The ser⁃um total antioxidant capacity in group Ⅳ was significantly higher than that in group Ⅰ ( P<0.05) . The serum malonaldehyde content in group Ⅳ was significantly lower than that in group Ⅰ ( P<0.05) . The serum gluta⁃thione peroxidase activity in groups Ⅳ and Ⅴ was significantly higher than that in group Ⅰ (P<0.05). 4) There were no significant differences in alkaline phosphatase activity and the contents of triglyceride and total cholesterol in serum among all groups ( P>0.05) . In conclusion, adding Bacillus subtilis into the diet can pro⁃mote growth performance, slaughter performance, antioxidant activity of Wulong geese aged from 12 to 16 weeks, significantly increase the availability of manganese, and reduce the dietary supplemental level of man⁃ganese. The optimal supplemental level of manganese is 70 mg/kg under dietary supplementation with 250 g/t Bacillus subtilis.关键词
