SYMPTOMS OF DISEASE DURING THE CLINICAL PERIOD OF MASTITIS IN COWS

Abstract

Mastitis is a very common disease in farm animals, which mainly causes great economic damage to dairy farms. This disease mainly causes a decrease in the amount of milk, deterioration of its quality, and early weaning of animals. For example: mastitis occurs among dairy cows: 20-25% when milking by hand, 35-40% when milking by machine. Weaning - 17.5% during the service period, and 20-23.7% during the lactation period. In this case: 1. The total amount of milk produced decreases by 15-20% and its fat content drops to 0.8-1%. The sanitary quality of milk decreases, that is, dairy products made from such milk are of poor quality. 2. The period of use of highly productive animals on the farm is reduced to 6-8 years. Cows become barren. 3. It causes diseases such as dyspepsia (diarrhea) in young animals and scarlet fever (scarlet fever) when consumed by young children.
