Abstract
Recently, due to the intensification of dairy cattle breeding, there has been an increase in the concentration of cattle, while unfavorable conditions are being created for the mother herd, helping to reduce their resistance to various unfavorable factors. Therefore, the study of clinical manifestations in the comorbid course of endometritis with purulentnecrotic diseases in the area of the hooves of highly productive cows, as well as a detailed comparison of the obtained indicators with clinically healthy animals and animals with a separate manifestation of endometritis and orthopedic pathology, in our opinion, is a very relevant area for scientific research. The research was supported by the Russian Science Foundation Grant No. 24-26-00172, https://rscf.ru/project/24-26-00172/. The experiment was approved by the bioethical commission of the Department of Veterinary Medicine of the Russian Biotechnological University, regarding the humane treatment of experimental animals. 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 purulent-inflammatory processes in the toes (n=27). Indicators obtained from clinically healthy animals (n=23) were used as control. Using the method of one-way analysis of variance (ANOVA), we established significant changes in the indicators of rumen contractions (F = 12.44; p<0.001), respiratory movements (F = 19.28; p<0.001), pulse (F = 8.21; p<0.001) and body temperature (F = 41.13; p<0.001).
