摘要
用氨基酸螯合物代替奶牛日粮中的无机微量元素添加剂以研究氨基酸螯合物对奶牛生产性能的影响。结果表明:氨基酸螯合物对提高产奶量,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10.34%(P<0.05),乳蛋白含量提高3.4%(P<0.05),奶料比、乳脂率和乳非脂固形物含量无明显变化。
This experiment was conducted to study the effect of amino acid chelate instead of Inorganic trace element on production performance.The result showed that milk production and milk protein of treatment group were Improved 10.34%(P<0.05)and 3.4%(P<0.05)in contrast to control group.Dairy milk fat,the ratio of milk and feedstuff,non fat solid of milk were not affected.
