摘  要:
试验选用泌乳3~5个月,2~5胎次,体重相近,健康无病,产奶量相近(P>0.05)的奶牛36头,随机分为4组,其中:对照组喂给基础日粮,试验1、2和3组分别在基础日粮中添加油菜籽(350 g/d.头)、菜油(150 g/d.头)和脂肪酸钙(200 g/d.头)。通过30 d对比饲养试验。结果表明:试验1、2、3组的奶牛日均产奶量分别比对照组相对提高0.88(P<0.05)、0.31(P>0.05)、0.70 kg/d.头(P<0.05)。各组间奶牛干物质采食量及饲料干物质利用率均无显著差异(P>0.05);试验1、2、3组牛奶中乳蛋白和非脂乳固体有增加的趋势,但不明显(P>0.05);试验1、2、3组与对照组的乳脂率无明显变化(P>0.05)。与对照组相比试验1组每头奶牛每天可增加纯收入1.08元,试验2组亏损0.06元,试验3组亏损0.14元;从而认为在日粮中添加油菜籽、菜油、脂肪酸钙可以提高奶牛产奶量,其中以添加油菜籽的经济效益最好。

摘  要:
36 healthy dairy cows whose milking days are 90-150,hypo-padding are 2-5,LW are similar were selected,and divided into four groups(P>0.05)according to Complete Random Design.Each group received one treatment,group4 was control group,group1,2 and 3 supplemented rapeseed,rape oil and fatty acid calcium respectively.After 30days experimentation,the results shown the daily milk yield of group 1,group2 and group3 enhanced 0.88(P<0.05),0.31(P>0.05),0.31(P>0.05),0.70(P<0.05) kg/h/d.No significant difference fund Between all groups' DMI and FCR;Even SNF shown an increased tendency,supplementation of rapeseed(350 g/h/d),rape oil(150g g/h/d) and fatty acid(200 g g/h/d) did not affect the composition of milk SNF(P>0.05).Supplementation of fatty acid(200g g/h/d) increased milk fat significantly,but.that of rapeseed(350 g/h/d),rape oil(150 g g/h/d) had no any positive effect on the composition of milk SNF(P>0.05).group1 profited extract 1.08 Yuan kg/h/d,group2 lost 0.06 Yuan,group3 lost 0.14 Yuan kg/h/d;Above results shown supplemented rapeseed(350g/h/d) to the dairy cow whose milking day are 90-150,increase economical efficiency,supplementation of fatty acid enhanced the milk quality.
