微量元素氨基酸螯合物对奶牛生产性能影响的研究

用微量元素氨基酸螯合物(简称氨基酸螯合物)代替无机微量元素,添加到奶牛日粮中饲喂奶牛,研究氨基酸螯合物对奶牛生产性能的影响,试验结果表明:氨基酸螯合物对提高奶牛产奶量、改善奶品质具有重要作用。试验期末,试验组奶牛产奶量与对照组相比提高11%(p<0.05),乳蛋白含量提高3.5%(p<0.05),乳脂率和乳非脂固形物含量等无明显变化。

Research on the Effect of Microelements Aminophenol Chelated on Yield Performance of Milch Cow

In this paper, the effect of aminophenol chelated microelements on the yield performance of milch cow was stu- died on this condition which adding aminophenol chelated instead of abio-microelements to everyday feedstuff of milch cows. The result indicted that: aminophenol chelated have a important effect on the improvement of yield and quality of milk. The milk yield of trial group was increased by 11% contrast against control one, content of milk albumen was in- creased by 3.5%, but the rate of milk fat and the concent of non-fat solid substances have no change.
