摘要
In order to further study the postpartum care technology of dairy cows,the effects of oral administration of propylene glycol or Ca-P-Mg mixture and compound oral rehydration salts on milk quality and SCC of dairy cows after birth were investigated. The results showed that the milk fat and dry matter contents in the dairy cows administered with Ca-P-Mg mixture and compound oral rehydration salts were higher than those in the dairy cows administered with propylene glycol（P 〈0.05）. However, there were no significant differences in milk sugar and protein contents and SCC between the two administration groups.
为了进一步研究奶牛产后灌服保健技术,试验采取对比的方法,测定了奶牛产后灌服丙二醇与钙磷镁合剂+复方口服补液盐的乳汁质量及牛奶体细胞数。结果表明:灌服钙磷镁合剂+复方口服补液盐组奶牛的乳脂率及乳干物质率较灌服丙二醇组均有提升,差异显著;而乳糖率、乳蛋白质率以及牛奶体细胞数组间差异不显著。
