Effects of Zymotic Grape Seed Meal on Digestive Physiology, Immune Organ Indices and Antioxidant Indices of Wulong Geese Aged from 5 to 12 Weeks
摘要
Abstract
This experiment was conducted to study the effects of dietary different zymotic grape seed meal lev-els on digestive physiology, immune organ indices and serum antioxidant indices of Wulong geese aged from 5 to 12 weeks, to find the appropriate supplemental level of the zymotic grape seed meal and its feed effect.A to-tal of 288 five-week-old Wulong geese were randomly divided into 6 groups with 6 replicates per group and 8 geese per replicate ( half male and half female) .Geese in the control group ( groupⅠ) were fed a basal diet, and the others were fed the basal diet supplemented with 2%( groupⅡ) , 4%( groupⅢ) , 6%( groupⅣ) , 8%( groupⅤ) , 10%( groupⅥ) zymotic grape seed meal, respectively.The experiment lasted for 8 weeks. The results showed as follows:1) compared with the control group, the activities of amylase, trypsin, lipase in duodenum and jejunum in group Ⅴ were significantly increased (P<0.01), the activities of amylase and trypsin in pancreas in group Ⅴ were significantly increased ( P<0.01 ); the activity of lipase in pancreas in groupⅣ was significantly increased ( P<0.01); the activity of pepsin in group Ⅴ was significantly increased (P<0.05).2) Compared with the control group, the number of Escherichia coli in intestinal tract in groupⅣwas significantly decreased ( P<0.05) , the number of Lactobacillus in intestinal tract in group Ⅴ was signifi-cantly increased ( P<0.05), but there were no significant differences between group Ⅳ and group Ⅴ ( P>0.05) .3) Compared with the control group, the intestinal villus height in groupⅣwas significantly increased (P<0.05); the thickness of muscle in group Ⅳ was significantly increased ( P<0.05); the crypt depth in group Ⅴwas significantly decreased ( P<0.01) .4) There were no significant differences on immune organ in-dices among all groups (P>0.05).Compared with the control group, the serum total antioxidant capacity in group Ⅴwas significantly increased ( P<0.01);the serum malonaldehyde content in groupⅣwas significant-ly decreased ( P<0.01 ) , the activities of total superoxide dismutase and glutathione peroxidase in serum in group Ⅴ were significantly increased ( P<0.01) .In conclusion, zymotic grape seed meal can improve diges-tive enzyme activity, optimize the structure of intestinal tissue, improve antioxidant function of Wulong geese aged from 5 to 12 weeks, and has no effect on immune organ index, and the dietary appropriate supplemental level is 6%to 8%.关键词
