摘要: 选用15头泌乳中期的荷斯坦奶牛,研究糊化羟甲基蛋氨酸钙对泌乳中期的奶牛产奶量及乳成分的影响。将试验牛分为3组,分别饲喂糊化羟甲基蛋氨酸钙(A组)、羟甲基蛋氨酸钙(B组)和对照组(C组),A组和B组的添加量分别为400 g和20 g。试验结果表明:A组和B组产奶量比C组分别提高4.97%和3.99%,差异显著(P<0.05);3组试验牛的采食量差异不显著(P>0.05);A组和B组乳脂率比C组提高5.26%和3.99% (P<0.05);3组试验牛乳蛋白率、非脂固形物、全脂固形物、乳糖都差异不显著(P>0.05)。本研究结果表明,补饲糊化羟甲基蛋氨酸钙能增加产奶量,提高乳脂率含量,提高奶牛的养殖经济效益。

Abstract: To research the influence of pastemethioninehydroxymethyl calcium and hydroxymethyl methionine calcium on milk yield and milk components of Holstein dairy cattle,15 individual of Holstein with highproducing in the middle stagers of lactation were arranged randomly into three groups,i.e, pastemethioninehydroxymethyl calcium(group A), hydroxymethyl methionine calcium(group B) and control(group C).Group A was adding 400 g paste-methionine-hydroxymethyl calcium and group B was 20 g hydroxymethyl methionine calcium. The results showed that the milk production in group A and group B(P<0.05) were increased by 4.97%and 3.99% respectively. Three groups had no difference(P>0.05) in intake feed. Milk fat percentage in group A and group B were significantly improved 5.26%and 3.80% respectively than group C. Whereas three groups had no differences(P>0.05)in milk protein percentage, milk sugar solids and solids-not-fat in milk. It can be concluded that Paste-hydroxymethyl -methionine calcium supplementation can advance milk production,increase milk fat percentage of dairy cattle to improve economic efficiency. 
