[Comprehensive method for the prevention of mastitis in cows].

Trials have been carried out in the course of two years to reduce the cases of clinical and subclinical mastitis and the losses thereof in the industrial raising of cows. As a result of mastitis control measures the outbreaks of the disease were decreased: by 58.8 per cent, and by the end of the second year--by 66.2 per cent (subclinical mastitis) and by 33.0, resp. 28.6 per cent (clinical mastitis). This went along with the increase in the milk yield--by 120 1 per cow in the first year, and 70 1--in the second year.
