| 摘 要： | 选择出生日期、胎次、产奶量和体重相近的16头健康荷斯坦奶牛,随机分成4组(对照组、试验1组、试验2组、试验3组),每组4头。对照组饲喂基础日粮,试验组在基础日粮中分别依次添加0.5、1.5 kg和2.5 kg的膨化全脂大豆,预试期12 d,正试期60 d,研究不同膨化水平全脂大豆对产奶性能的影响。结果表明:试验1组、2组和3组的产奶量和标准乳产量均显著高于对照组(P<0.05),试验组间差异不显著;乳脂率试验1组、2组显著高于对照组(P<0.05),试验3组和对照组差异不显著(P>0.05);乳蛋白率试验2组、3组显著高于对照组(P<0.05),对照组和试验1组差异不显著(P>0.05);而对乳中非脂固形物的影响,4个组间均差异不显著(P>0.05)。综合考虑在奶牛日粮干物质中添加1.5 kg的膨化全脂大豆对提高产奶量和乳品质是最有利的。

| Abstract: | To study the effect of different levels of extruded full fat soybean on milk performance.Sixteen healthy Holstein cows with similar parturition date,parity,milk yield and body weight were randomly divided into 4 groups of 4 cows(control group,group 1,group 2 and group 3).The control group was fed with basal diet and group 1,2 and 3 were fed with basal diet added 0.5,1.5 kg and 2.5 kg extruded full fat soybean.Pre-trial period were 12 d,test period was 60 d.The results showed that:Standard milk yield and milk performance of group 1,2 and 3 were higher than those of control group significantly(P < 0.05),and there were no significant difference among the test groups;Milk fat of group 1,and group 2 were higher than that of control group and group 3 significantly(P < 0.05),but group 3 and control group showed no significant difference(P > 0.05);Milk protein of group 2 and group 3 were higher than that of control group and group 1 significantly(P < 0.05),but group 1 and control group showed no significant difference(P > 0.05);There were no significant differentce in non-fat solids among 4 groups.The results indicated that in diet of Holstein cows to add 1.5 kg of extruded full fat soybean is the most beneficial. |
