Influence of Medicinal Plant Extracts on Prevention of Cattle Postpartum Complications
In increasing the efficiency of using the breeding stock of cattle, an important role is played by the comprehensive implementation of zootechnical and veterinary measures in farms, timely detection and treatment of obstetric and gynecological diseases, and preventive measures to prevent the development of such diseases [1, 2]. The consequences of the pathology of the birth and postpartum period in cows are such diseases as the placenta retention, endometritis, uterus subinvolution, and ovarian dysfunction, which, according to the literature data, are recorded in 30-90% of cows after pathological calving . This article presents the results of determining the effect of extracts of such medicinal plants as Maral Root and Stinging Nettle in feeding recipient cows during the dry period to prevent postpartum complications in animals and reduce the recovery period of the reproductive system. It was found that on the 30th day, animals that received additional medicinal extracts in the diet showed an increase in the content of neutrophils and platelets in the blood and protein fractions of blood serum, which indicates an increase in the resistance of the animal's body. An increase in the bactericidal, lysozyme activity of the blood serum of recipient cows and the phagocytic activity of leukocytes also suggests an increase in the immune response from the animal's body in response to the penetration of foreign microflora inside the organism. Based on the results of the studies, it was recommended to add a two-component phytobiotic feed additive to the main diet based on extracts of medicinal plants Maral Root and Stinging Nettle at a dose of 50 g per head a day in the ratio of components: 100 kg of compound feed, 0.5 kg of Maral Root extract, 2.5 kg of Stinging Nettle extract.
