EXAMINING OF ERGOTROPIC EFFICACY VETOM-1.1 AND FAVORIN ON CHICKENS
Currently conducting a cost-effective intensive meat poultry without the use of additional biological promoters in broiler chickens is almost impossible. The spectrum of preparations ergotropic actions are quite broad and varied. The aim of the research was the comparative evaluation of ergotropic effectiveness of probiotics Vetom-1.1, Favorin individually and their combinations on the basis of intensity of growth and preservation of broiler chickens, morphological and biochemical parameters of blood, the quality of their meat. The experience was conducted in terms of a mini poultry farm of the physiological complex of the Federal State Budgetary Educational Institution of Higher Education “Belgorod State Agricultural University named after V. Gorin” on 400 chickens-broilers of cross Hubbard F 15 treated with the additive at a dose of 0.35 % of feed 1 time a day the entire cultivation period, separately or in combination half-dose. Found that probiotics increased the gain of the capes of the body, increases the safety of live¬stock. Average daily gain for the enrichment of diets with Vetom-1.1 was higher than in the control, 22.5 %, its combi¬nation with Favorin - by 11.2 %, one Favorin - 9.5 %. In the group treated with Vetom-1.1 the average live weight for slaughter amounted to 2060g, control - 1723 g, Favorin - 1840 g and a combination of probiotics - 1870. Lower results from Favorin may explain its negative effect on hematological parameters (trend of reduction in hemoglobin levels, increased leukocyte count and a statistically significant increased alanine aminotransferase activity). Both probiotic increased content in the breast muscle of nitrogenous substances, improved tasting properties of meat and meat broth, reduced the calcium content in the femur. Vetom-1.1 had a stronger than Favorin ergotropic influence, but reduced the bones phosphorus cumulation. The combination of Vetom-1.1 with Favorin its positive influence on the organism de¬creased.
