摘　　要：生物发酵饲料是通过好氧菌与厌氧菌轮回发酵,产生有益的菌种代谢产物和底物分解物,富含有益菌、小肽、酶、有机酸、核苷酸等,可平衡肠道微生物菌群,抑制有害微生物生长,显著提高动物生长性能,提升机体免疫力,改善畜产品品质及风味。为研究日粮添加生物发酵饲料对山羊育肥效果的影响,该文通过对72只体型、体重相差不大的山羊进行对照试验,表明日粮添加生物发酵饲料可以明显提高饲粮粗蛋白、粗脂肪、酸性洗涤纤维以及中性洗涤纤维的表观消化率,对肉羊的平均日增重有促进作用,能显著提高肉羊的屠宰率。Biofermented feed is produced by cyclic fermentation of aerobic bacteria and anaerobic bacteria to produce beneficial bacterial metabolites and substrate decomposition.It is rich in beneficial bacteria,small peptides,enzymes,organic acids,nucleotides,etc.,which can balance intestinal microbial flora,inhibit the growth of harmful microorganisms,significantly improve animal growth performance,enhance body immunity,and improve the quality and flavor of animal products.In order to study the effect of dietary supplemented biological fermented feed on the fattening effect of goats,this paper conducted a controlled experiment on 72 goats with similar body size and weight.The results indicated that dietary supplementation of bio-fermented feed can significantly improve the apparent digestibility of dietary crude protein,crude fat,acid detergent fiber and neutral detergent fiber,promote the average daily gain of mutton sheep,and significantly improve the slaughter rate of mutton sheep.
