The course of the postpartum period in cows in the presence of concomitant pathology

Abstract

The decrease in productivity in cows is directly related to the pathologies of the organs of the reproductive system that occur at the end of the transit period, therefore it is important to improve the methods of diagnosis and preventive therapy of cows in this period. The purpose of the work was to establish the forms of pathologies that occur in the transit period in cows, their interrelationship and the causes that cause them in terms of seasonal dynamics. When conducting research, morphological, clinical (examination, palpation), laboratory (bacteriological studies of the uterus), and statistical (statistical reliability) methods were used. The research was conducted in the limited liability company “Milk of the Fatherland” in 2 departments where unattached housing is used. The occurrence of subinvolution of the uterus against the background of litter retention and persistent corpus luteum was established by 9.5% more in the 1st department. A 43.5% correlation of the prevalence of delayed involution with endometritis was revealed. An increase, 12.8% in January and up to 14.1 in February, of cases of subinvolution of the uterus was established, while in May the similar indicator was 5.0%. The prevalence of persistent corpus luteum was established up to 16.8%, luteal cyst – up to 1.7%, ovarian follicular cyst – 2.1%. The presence of microflora in the uterine cavity (E. coli, Ps. aeruginosa and S. aureus – 49.8% S. aureus and E. coli – 33.5%, Pr. vulgaris and E. coli – 16.7%) provoked the occurrence inflammatory processes: chronic endometritis – 10.4%, vulvovaginitis – 18.1%, cervicitis – 21.4%. Research results can be used to develop new and improve existing methods of treatment of cows with pathology of genital organs in the transit period in farms of different forms of ownership.
