ЗАБОЛЕВАНИЯ МОЛОЧНОЙ ЖЕЛЕЗЫ И ПОЛОВЫХ ОРГАНОВ КОРОВ В ПОСЛЕРОДОВЫЙ ПЕРИОД

Abstract

Mastitis-endometritis syndrome at the beginning of lactation in cows is one of the most economically significant diseases of dairy cattle, since the measures of treatment and prevention are financially costly and, very importantly, difficult to recover. In this regard, further study of the relationship of these diseases in the postpartum period is of great practical importance. In the course of work, the percentage of cows with placenta retention, endometritis and mastitis, separately, as well as jointly occurring in the postpartum period (the first month after calving) was determined. It was found that of 590 calving cows and heifers in the first month after calving revealed 322 or 54.5% of animals with postpartum pathology, including endometritis, detention of the afterbirth and mastitis. Among postpartum diseases of cows in the surveyed economy dominated by endometritis (43.2% of the number of calving cows) with various forms of inflammation of the endometrium. Detention of placenta and mastitis amounted to 20.0% and 17.8% of the number of calving animals or 2.2 and 2.4 times less compared to endometritis. The analysis of the results found that the number of postpartum diseases averaged 0.8 per calving cow or 1.5 per sick cow (P>0.999). A direct average relationship between the diseases of cows in the postpartum period of endometritis and mastitis was established, with a correlation coefficient (r) of 0.48; a direct strong relationship between endometritis and placenta retention was 0.83 at P>0.999.
