复合益生菌发酵饲料对肥育猪消化与生产性能的影响

The effects of complex probiotics fermented feed on digestion and performance of finishing pigs

为了研究非常规饲料经复合益生菌发酵对肥育猪生产与消化性能的影响,选择65 kg左右的三元杂交猪(杜×长×大)75头,随机分成5组,每组15头,进行饲养试验。结果表明:非常规饲料经益生菌发酵后,饲料本身的品质得到了改善;生长肥育猪饲喂益生菌发酵非常规日粮后,各组均有提高肥育猪日增重的趋势,与对照组相比,发酵1组提高肥育猪日采食量7.13%,降低料肉比3.22%,差异均不显著;复合益生菌发酵后,各组饲料干物质、有机物、粗蛋白、粗纤维和磷的表观消化率均有极显著提高。复合益生菌发酵饲料可显著提高饲料各营养素的表观消化率,提高肥育猪的日采食量和日增重,改善料肉比,并减少环境污染。

To study the effects of unconventional complex probiotics fermented feed on the performance and digestion of finishing pigs,75 three-way cross pigs（Duroc×Landrace×Large Yorkxia） weighing about 65 kg were randomly divided into 5 groups,each group having 15 pigs.The experiments showed that after fermented by probiotics the unconventional feed improved in quality;Fed on the unconventional complex probiotics fermented feed,the finishing pigs of each group presented a trend to improve the daily gain;In comparison with the control group,Group 1 fed on the unconventional probiotics fermented feed with a normal protein level increased the daily feed intake by 7.13%but decreased by 3.22%in feed/meat ratio,though their differences were not significant（P0.05）;Feeding on the complex probiotics fermented feed very significantly improved the apparent digestibility of dry matter,organic matter,crude protein,crude fiber and total phosphorus（P0.01）.It was concluded that using the complex probiotics fermented feed could significantly improve the apparent digestibility of every nutrient of feed,increase the daily feed intake and daily gain of the finishing pigs,and improve the feed conversion ratio,thus decreasing the environmental pollution.
