该研究选取240头不同泌乳阶段、1～8胎次的荷斯坦奶牛，探讨影响牛奶中体细胞数以及产奶量和乳成分的某些因素。同时，12头健康奶牛、15头亚临床乳房炎奶牛以及15头临床乳房炎奶牛分别分为3组，第1组不添加蛋氨酸锌，第2、5组分别添加蛋氨酸锌5g／d·头和10g／d·头。亚临床和临床性乳房炎奶牛乳房内注射抗生素（100mg），直到完全康复。研究结果显示，冬季乳中体细胞数最高（P〈0．05），接着是夏季，最低的是秋季。体细胞数的变化是随着泌乳开始产奶量上升到高峰期的过程中呈现下降趋势，之后显著升高（P〈0．05），并且随着泌乳期的增加也在升高。正常奶牛、亚临床乳房炎奶牛和临床乳房炎奶牛的比例分别为77．71％、15．82％以及6．46％。产奶量和乳成分以及产奶收入都随着体细胞数的增加而显著降低（P〈0．05）。补充蛋氨酸锌导致乳中体细胞数显著下降（P〈0．05）。亚临床和临床乳房炎补充蛋氨酸锌显著降低了乳中体细胞数、导电性、康复时间以及与未添加组奶牛相比消耗的费用（P〈0．05）。
