In this article, the biochemical parameters of blood in healthy cows and cows affected by mastitis were studied experimentally. The results showed that with the development of pathological processes in the udder, the levels of total protein and glucose decreased compared to healthy cows, while the levels of bilirubin, urea, creatinine, and cholesterol were higher than in healthy animals.
It was also determined that during the development of subclinical mastitis in lactating cows, the level of amylase decreased by 4% and alkaline phosphatase decreased by 9.5%.
Based on the obtained results, it was concluded that the development of inflammatory processes in the udder and the use of effective therapeutic drugs significantly affect the morphological and biochemical parameters of cows’ blood.
