| 摘 要： | 本研究在饲粮中分别添加 ３个不同剂量的玉米源异麦芽寡糖菌质粉（ＩＢＳ），旨在研究其对黄羽肉鸡生长性能和内源性激素分泌的影响。选择 １日龄黄羽肉鸡 ２７０只，公母各占 １／２，随机分成 ５组。对照 １组饲喂基础饲粮，对照 ２组在基础饲粮中添加 ４．２７ｇ／ｋｇ市售食品级低聚异麦芽寡糖粉，试验 １、２、３组分别在基础饲粮中添加 ６、１２、２４ｇ／ｋｇＩＢＳ。结果表明：１）与对照 １组相比，试验 １、２、３组死亡率分别降低 ３３．３０％、４９．９５％、４９．９５％；１～５２日龄，试验 １、２、３组平均日增重分别提高 ８．８０％（Ｐ＜０．０１）、１１．０２％（Ｐ＜０．０１）、７．８０％（Ｐ＜０．０１）；试验 １、２、３组料重比分别降低 ８．７３％（Ｐ＜０．０５）、９．０９％（Ｐ＜０．０１）、６．９１％（Ｐ＜０．０５）；试验 ２组血清中甲状腺素含量提高 ８．６８％（Ｐ＜０．０５）；试验 ３组血清中胰高血糖素含量降低 ２４．７５％（Ｐ＜０．０５）；在血清胰岛素动态变化过程中，采食后 １ｈ，试验 １组提高 ４０．３１％（Ｐ＜０．０５），采食后２ｈ，试验 ２组提高 ４０．０９％（Ｐ＜０．０５）；在血清生长激素动态变化过程中，采食后 １ｈ，试验 ３组提高 ３５．１８％（Ｐ＜０．０５），采食后 ２ｈ，试验 ２、３组分别提高 ４８．２６％（Ｐ＜０．０５）、４２．７２％（Ｐ＜０．０５）；试验 ２、３组血清中生长激素含量总体平均值分别提高 ２３．６５％（Ｐ＜０．０５）、２６．２９％（Ｐ＜０．０５）。２）与对照２组相比，试验２、３组死亡率均降低２４．９７％；１～５２日龄，试验１、２、３组平均日增重分别提高 ６．５７％（Ｐ＜０．０５）、８．７５％（Ｐ＜０．０１）、５．５９％（Ｐ＜０．０５）；在血清胰岛素动态变化过程中，采食后 ２ｈ，试验 ２组提高 ４４．５５％（Ｐ＜０．０５）；在血清生长激素动态变化过程中，采食后 ２ｈ，试验 ２、３组分别提高 ５０．２４％（Ｐ＜０．０５）、４４．６３％（Ｐ＜０．０５）；试验 ３组血清中生长激素含量总体平均值提高 ２３．８０％（Ｐ＜０．０５）。结果提示，黄羽肉鸡饲粮中添加一定剂量的 ＩＢＳ，对其生长性能、激素分泌有促进作用，且在本试验的 ３个剂量中，以添加 １２ｇ／ｋｇＩＢＳ综合效果最佳。

| 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. |
