Influence of a phytobiotic complex on indicators of natural resistance in feeding of cows

Abstract

An increase in the number of livestock no longer brings those economic dividends, on the contrary, there is an economic recession. Agricultural specialists, veterinarians are intensively engaged in this issue, looking for options to reduce economic losses. The research and production experiment was carried out in the collective farm "Leninsky Put Kolkhoz" in the Pushkinogorsk district of the Pskov region, which has a dairy direction. The aim of the study was to study the effect of the phytosorption complex on the immunological parameters of pregnant cows and newborn calves. For the experiment, two groups of pregnant cows were created, 20 heads each. The animals were selected according to the principle of similarity, taking into account the weight of the animals, productivity and lactation number. The cows of the control group received a standard diet, the animals of the experimental group were additionally injected with a phytobiotic complex at a dose of 60 g / head. The phytobiotic complex was introduced into the diet 60 days before calving. The drug was prescribed according to the scheme: 14 consecutive days, with a two week break. During the experiment, indices of natural resistance and indices of humoral immunity were studied in the blood and colostrum of experimental cows. Having received colostrum of better immunological quality, we found that the calves of the experimental group had a higher humoral immunity. So the increase in immunoglobulins G, A, M, compared with the control group was 41,1; 25,41 and 32.95%. Indicators of BASK, LASK and Phagocytic activity of blood serum also increased by 1.5; 14.28, 6.5% compared with the control. By receiving the phytosorption complex, the experimental cows were able to maintain their immunological status at a high level.
