BIOLOGICAL FUNCTIONS OF CAROTENOIDS AT CATTLE REPRODUCTION

abstract 1291705080 issue 129 pp. 1124 – 1136 31.05.2017 ru 87
Carotenoid preparations are quite widely used in a health care, but in the veterinary and animal husbandry, their use is limited. In terms of livestock farms of the Krasnodar region and the Rostov region at the biochemical monitoring studies of the cattle blood the lack of carotene in the serum is revealed from 45 to 100 % of the samples. To study the biological function of carotenoid we used preparations, which are the oily solutions for injections: β-carotene (manufactured by FS 42-3867, which is produced from the biomass culture of the fungus Blakeslea trispora) and lycopene, emitted from plants. The cows in the test groups during the dry period and within two weeks after birth got carotenoid preparation subcutaneously at a dose of 10 ml per animal with an interval of 7 days. As a result, it was found out that the application of carotenoids has the most favorable conditions for the flow of labor and the postnatal period, which are manifested in the decrease in obstetric and gynecological diseases in cows and reduce the period of infertility. In the experimental groups the levels of vitamin A and carotene1,3 times higher (1,26 ± 0,14 μmol/L vs. 0,97 ± 0,09 μmol/L ) 1,8 times (0,34 ± 0 03 mg /% vs. 0.61 ± 0.11 mg /%) respectively in comparison with the parameters of the intact animals at a high level of confidence (P < 0,05). Phagocytic number and percentage of digestion of neutrophils increased by 8,5 %, the difference in the number of B-cells reached 9,1%, T-cells – 6,7%. In a humoral immunity found a significant increase in Ig A. After comparison of the level of lysozyme activity of blood serum was observed its reduction in all animals immediately after birth, but in the experimental groups this process was less pronounced. The use of carotene preparations helps to reduce the concentration of lipid peroxidation products in the body of cows (diene conjugates - by 16,6 %, ketodienes - by 35,7 %, malondialdehyde – by 11,3 %), which creates favorable conditions for the flow of the metabolic processes associated with ensuring the normal childbirth and post-partum involution of the genitals. In the group of cows, receiving the carotenoid lycopene, the dyspepsia morbidity of the newborn calves compared to a control decreased by 26,7 %, bronchopneumonia - by 13,3 %
