Effect of low rate vacuum on the diseases of the udder at machine milking of cows

, : Effect of low rate vacuum on the diseases of the udder at machine milking of cows. Veterinarno Meditsinski Nauki 24(2): 40-45

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.
