Effects of Activity Flour of Isomalto-Oligosaccharides Bacterium Substance from Corn on Growth Performance and Hormone Secretion of Yellow-Feathered Broilers
摘要
Abstract
In order to study the effects of activity flour of isomalto-oligosaccharides bacterium substance from corn (IBS) with three doses on growth performance and hormone secretion of yellow-feathered broilers, a total of 270 one-day-old yellow-feathered broilers were allocated to 5 groups, including control groups 1, 2 and experimental groups 1, 2 , 3. The control group 1 was fed basal diets, control group 2 was fed basal diets added with 4. 27 g/kg food-grade isomalto-oligosaccharides, and experimental groups were fed basal diets added with 6, 12, 24 g/kg IBS, respectively. The results showed as follows: 1) compared with control group 1, the mortality in experimental groups 1,2,3 was decreased by 33. 30% ,49. 95% ,49. 95% ; at 1 to 52 days of age, the average daily gain in experimental groups 1,2,3 was increased by 8. 80% (P <0. 01) , 11. 02% (P <0. 01) , 7. 80% (P < 0. 01) , and the feed/gain in experimental groups 1,2,3 was decreased by 8. 73% (P<0.05) , 9.09% (P<0.01) , 6.91% (P<0.05) ; serum T4 content in experimental group 2 was increased by 2. 88% (P <0. 05) ; serum Glu content in experimental group 3 was decreased by 24. 75% (P < 0. 05) ; in the process of dynamic changes, serum Ins content in experimental group 1 was increased by 40.31% (P<0.05) at 1 h after feeding, and that in experimental group 2 was increased by 40. 09% (P < 0. 05) at 2 h after feeding; in the process of dynamic changes, serum GH content in experimental group 3 was increased by 5. 18% (P<0.05) at 1 h after feeding, that in experimental groups 2, 3 was increased by 48. 26% (P <0. 05) , 42. 72% (P <0. 05) at 2 h after feeding, and overall average of that in experimental groups 2 , 3 was increased by 23. 65% (P <0. 05) , 26. 29% (P <0. 05). 2) Compared with control group 2, the mortality in experimental groups 2, 3 was decreased by 24.97% , 24.97% ; the average daily gain of broilers at 1 to 52 days of age in experimental groups 1,2,3 was increased by 6. 57% (P <0. 05) , 8. 75% (P<0.01) , 5. 59% (P<0.05) ; in the process of dynamic changes, serum Ins content in experimental group 2 was increased by 44. 55% (P <0. 05) at 2 h after feeding; in the process of dynamic changes, serum GH content in experimental groups 2 , 3 was increased by 50. 24 % (P < 0. 05) , 44. 63 % (P < 0. 05) at 2 h after feeding, and overall average of that in experimental group 3 was increased by 23. 80% (P <0. 05). In conclusion, there is a positive effect on growth performance and hormone secretion of yellow-feathered broilers by supplemented with IBS in diets, and the effect of feeding basal diet added with 12 g/kg IBS is the best among three doses in this trial.关键词
