| 摘 要： | 在玉米-大豆浓缩蛋白型低寡糖基础日粮中分别添加0、0.50%、1.00%或2.00%的大豆寡糖,研究了不同添加量大豆寡糖对肉仔鸡肠道pH值和盲肠短链脂肪酸的影响。选用192只1日龄AA肉公鸡,随机分成4个处理组,每个处理设6个笼(重复),每笼8只鸡。结果表明:大豆寡糖对18、36日龄肉仔鸡十二指肠和空肠食糜pH值的影响无明显规律,各处理组之间无显著性差异(P0.05);随着大豆寡糖水平的增加,盲肠食糜pH值呈下降的趋势(P0.05),1.00%大豆寡糖添加组18、36日龄肉仔鸡盲肠食糜pH值为最低水平,且显著低于对照组(P0.05)。低寡糖日粮中添加不同剂量大豆寡糖,大幅度增加肉仔鸡盲肠食糜中乙酸和短链脂肪酸总量的浓度(P0.05);添加1.00%或2.00%大豆寡糖,显著增加18日龄肉仔鸡盲肠食糜中丁酸占短链脂肪酸总量的摩尔百分比(P0.05)。 |

| Abstract: | This experiment was conducted to investigate the effects of gradient dietary supplemental soybean oligosaccharides (SO) on the caecal pH value and short-chain fatty acids in broilers. A total of 192 1 day-old male Arbor Acre broilers were randomly allotted into 4 treatments of 6 cages which contained 8 birds and were fed one of the 4 diets with SO added to an oligosaccharide-low basal diet of corn-soybean protein concentrate at the dosage of 0,0.50%,1.00% and 2.00%,respectively. The results indicated that n... |
