摘要/Abstract

摘要： [目的]试验旨在研究复合植物提取物对患乳房炎奶牛泌乳量和乳汁理化相关指标的影响。[方法]选取患乳房炎奶牛24 头,每组12 头,分为试验Ⅰ组、Ⅱ组,试验Ⅰ组采用5 倍稀释后的复合植物提取物治疗乳房炎,试验Ⅱ组作为阳性对照,采用常规抗生素治疗。另选取健康奶牛12 头为试验Ⅲ组,作为阴性对照,采用10 倍稀释后的复合植物提取物。于用药前1 天和治疗第7 天,测定每组奶牛的泌乳量、pH值、电导率、体细胞数、丙氨酸氨基转移酶（ALT）、乳酸脱氢酶（LDH）和白蛋白（ALB）指标。[结果]用药前1 天,试验Ⅰ组、Ⅱ组的电导率、体细胞数极显著高于试验Ⅲ组,产奶量显著低于试验Ⅲ组和pH值显著高于试验Ⅲ组。试验Ⅰ组和试验Ⅱ组经过7 天治疗后,试验Ⅱ组电导率、体细胞数、LDH、ALB、ALT均极显著高于试验Ⅲ组,产奶量显著低于试验Ⅲ组,pH值显著高于试验Ⅲ组,而试验Ⅰ组与试验Ⅲ组比较,各项指标无显著差异。[结论]复合植物提取物可以减轻乳房炎炎症,促使乳汁相关指标与健康奶牛基本一致,对防治乳房炎有显著成效。

Abstract: The aim of the experiment is to investigate the effects of compound plant extracts on milk production and milk physicochemical indicators in cows with mastitis. 24 cows with mastitis were selected, with 12 cows in each group. They were divided into Experiment Group I and Experiment Group II. Experiment Group I was treated with 5-fold diluted compound plant extracts for mastitis, while Experiment Group II was used as a positive control and treated with conventional antibiotics. Another 12 healthy cows were selected as the experimental group III, as a negative control, using compound plant extracts diluted 10 times. On the 1st day before medication and the 7th day of treatment, milk production, pH value, electrical conductivity, somatic cell count, alanine aminotransferase (ALT), lactate dehydrogenase (LDH), and albumin (ALB) indicators were measured in each group of cows. The results showed that one day before medication, the electrical conductivity and somatic cell count of Group I and Group II were significantly higher than those of Group III, the milk production was significantly lower than that of Group III, and the pH was significantly higher than that of Group III. After 7 days of treatment, the electrical conductivity, somatic cell count, LDH, ALB, and ALT of Experiment Group I and Experiment Group II were significantly higher than those of Experiment Group III, and the milk production was significantly lower than that of Experiment Group III. The pH was significantly higher than that of Experiment Group III. However, compared with Experiment Group III, there was no significant difference in all indicators. This indicates that compound plant extracts can reduce breast inflammation, promote the consistency of milk related indicators with healthy cows, and have significant effects on preventing and treating mastitis.
