Morphological and functional blood parameters in the comorbid course of endometritis and purulent-necrotic diseases of the hoof area in highly productive cows

Abstract

In veterinary medicine, there is a problem of the comorbid course of reproductive function disorders and purulent-necrotic lesions in the toe area of cows. The research was carried out on the basis of Voskresenskoye JSC, Voskresensky district, Moscow region, with a total population of 1,450 heads of cattle, including 830 cows. The material for the study was cows with endometritis (n=28), animals with orthopedic pathology (n=25) and with a comorbid course of postpartum endometritis and purulentinflammatory processes in the toe area (n=27). Indicators obtained from clinically healthy animals (n=23) were used as control. From animals in the control and experimental groups, blood was taken in the morning before feeding from the jugular vein for morphofunctional studies. In experienced cows that had lesions in the limbs before or after birth, the likelihood of gynecological diseases associated with morphological disorders in the ovaries increased. The significant spread of these types of pathology is the direct cause of prolonged anaphrodisia of cows and a decrease in the level of reproduction of the herd with a high incidence of limb diseases. It has been established that the clinical manifestation of the comorbid course of orthopedic and obstetric-gynecological pathology has a more severe clinical manifestation than in the course of individual diseases. The study was supported by the grant from the Russian Science Foundation No 24-26-00172, https://rscf.ru/project/24-26-00172/.
