Abstract
Investigations were carried out with two groups of cows at first lactation to elucidate the effect of low rate vacuum on the health status of the mammary gland. The clinical, cytologic, and microbiologic studies were performed in dynamic. It was found that the milking of cows with the use of 39.9 kPa vacuum produced a negative effect on the normal udder. It led to secretory troubles, subclinical mastitis, and latent infection.
摘要
首先对两组初产奶牛进行了调查，以阐明低真空度对乳腺健康状况的影响。对其进行了动态的临床、细胞学和微生物学研究。结果发现，使用39.9 kPa真空度挤奶会对奶牛正常乳房产生负面影响。这会导致分泌问题、亚临床乳腺炎和潜伏感染。
