生物发酵饲料对肉牛生长性能、养分表观消化率及粪便菌群的影响OA北大核心CSTPCD
Effects of bio-fermented feed on growth performance,nutrient apparent digestibility,and fecal flora of beef cattle
试验旨在研究生物发酵饲料对肉牛生长性能、养分表观消化率、粪便菌群及血清抗氧化指标的影响.选用体重在550 kg左右的西杂牛32头作为试验动物,随机分为2组,每组4个重复,每个重复4头牛.对照组肉牛饲喂基础饲粮,试验组肉牛饲喂5％生物发酵饲料替代基础饲粮.预试期15 d,正式试验期90d.结果表明:与对照组相比,饲喂生物发酵饲料后,肉牛的末重、平均日增重分别显著提高了 2.45％和23.29％(P＜0.05),而料重比显著降低了 18.34％(P＜…查看全部>>
The experiment was designed to study the effects of bio-fermented feed on the growth performance,nutrient apparent digestibility,fecal flora,and serum antioxidant indexes of beef cattle.Thirty-two head of'Simmental×Local'cattle cattle weighing about 550 kg were selected as test animals and randomly divided into two groups with four replicates each and four cows in each replicate.The control group was fed with basal ration,and the experimental group was fed w…查看全部>>
