摘　　要：12头荷斯坦奶牛随机分为试验组(添加金属蛋氨酸络合物)和对照组(添加微量元素硫酸盐),供试日粮及营养水平完全相同,正试期60天。结果表明:试验组比对照组平均日产奶量提高4.50%,差异显著(P〈0.05)。Twelve Holstein were randomly divided into experimental group(with Metal Methionine Complex)and control group(with Microelement Sulphuric salt),ration and nutrient level were same ,the experimental period was60days.The re-sult showed that the daily milk production of experimental group was4.50%highter than those of control group(P<0.05).
