[Effect of low vacuum on the health status of the udder in the machine milking of cows].
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.
