摘要: 本试验选用1~3胎次患有隐性乳房炎的体重600 kg泌乳荷斯坦牛36头,随机均分为对照组和试验组,试验组奶牛每天服用200 g的红岩草提取物。乳酶活性测定结果表明,试验7 d组和14 d组的髓过氧化物酶(MPO)、乳酸脱氢酶(LDH)、乳过氧化物酶(LP)、N-乙酰-B-氨基葡糖糖苷酶(NAG)活性均极显著低于对照组(P<0.01);CMT法检测结果表明,试验7 d组和14 d组的治愈率分别为55.56%和77.78%;药物安全性评价结果表明,本试验中的红岩草提取物添加量并未造成试验7 d和14 d组奶牛的肝脏、肾脏功能指标变化,具有较高的安全性,可用于兽医临床。

Abstract: The 36 subclinical mastitis dairy cows of 600 kg weight and 1 to 3 parity were selected for the experiment,and randomly distributed equally into control group and test group. The test group dairy cows were taking 200 g of extract of saxifrage daily. Results showed that enzyme activity of myeloperoxidase enzyme (MPO), lactate dehydrogenase (LDH), lactoperoxidase (LP) and N-acetyl-B-amino-glucosidase (NAG) in the test group 7 and 14 d were significantly lower than the control group(P<0.01); CMT assay showed that the cure rates of test group 7 and 14 d were 55.56% and 77.78%, respectively; drug safety evaluation showed that using the extract of saxifrage had not cause changes in liver and kidney function indicators in test group 7 and 14 d, it indicated that the extract of saxifrage could be used in veterinary clinic safely.
