摘　　要：以分娩4周内的137头荷斯坦牛为试验动物,筛选19头酒精检测阳性且CMT检测阴性的牛只作为试验组,14头酒精检测和CMT检测均呈阴性的牛只为对照组,进行乳汁理化指标、血细胞、血液生化指标的检测。结果表明,低酸度酒精阳性乳在泌乳初期的发病率为42.34%,多发于泌乳天数低的奶牛,与隐性乳房炎无相关性,可引起乳脂率升高、乳糖率降低;试验组奶牛血液血红蛋白、白细胞、淋巴细胞、中间细胞升高,中性粒细胞降低,血清总蛋白、球蛋白、钙、镁、葡萄糖和胆固醇降低,血清钠、β-羟丁酸升高。137 Holstein cows deliveried in 4 weeks were selected as the experimental animals. 19 alcohol test positive and CMT test negative cows were selected as the experimental group. 14 alcohol test negative while CMT test negative cows were selected as the control group. Milk physical and chemical indicators, blood cell index and blood biochemical parameters were detected. The results showed that the incidence of low acidity alcohol positive milk （APM） was 42.34% during the early location. Low acidity APM was more likely to occur in early location cows. There was no correlation between low acidity APM and subclinical mastitis. The lactose in the milk and hemoglobin, WBC, lymphocyte, intermediate cell, neutrophil, total protein, globulin, calcium, magnesium, glucose, cholesterol in the blood of the cows with low acidity APM were significantly decreased. The milk fat percentage, the sodium and β-Hydroxybutyrate in the serum were significantly increased.
