酵母核苷酸对奶牛生产性能、乳品质、血清指标及经济效益的影响OA北大核心CSTPCD
Effects of yeast nucleotides on production performance,milk quality,serum indexes and economic benefits of dairy cows
试验旨在研究酵母核苷酸对奶牛生产性能、乳品质、血清指标及经济效益的影响.选择体重、胎次、产奶量相近的40头健康荷斯坦奶牛,随机分为4组,每组10个重复,每个重复1头奶牛.对照组饲喂基础饲粮,试验1组、试验2组和试验3组分别在基础饲粮中添加0.2％、0.4％和0.8％酵母核苷酸.预试期10 d,正式试验期60 d.结果显示,与对照组相比,试验3组奶牛的平均日采食量显著升高(P＜0.05).试验2组和试验3组奶牛的平均日产奶量显著升高(P＜0.05)…查看全部>>
The experiment aimed to investigate the effects of yeast nucleotides on the production performance,milk quality,serum indexes,and economic benefits of dairy cows.Forty healthy Holstein cows with similar body weight,parity,and milk yield were selected and randomly divided into four groups with ten replicates in each group and one cow in each replicate.The control group was fed a basal diet,while the experimental group 1,group 2,and group 3 were supplemented w…查看全部>>
