Application of complex phytobiotic feed additive in diets for meat quail breed

The article presents the results of scientific research to determine the influence of complex phytobiotic feed additive in the composition of complete mixed fodders on zootechnical indicators of meat quails. The paper presents the results of a scientific study on the effect of a complex phytobiotic feed additive in complete feed on the zootechnical performance of growing meat quails. The studied complex phytobiotic feed additive consists of turkey fat, pumpkin paste, celery paste, cereal sprouts and perlite. The experiment was conducted according to the standard methodology in the vivarium of the Krasnodar Research Centre for Animal Husbandry and Veterinary Medicine on young quails of the Texas White breed. In the process of the study, three groups were formed from day-old chicks by the pair-analogy method. For the first 10 days all birds received the same feed without additives. From the 11th to the 42nd day, the representatives of the control group received complete mixed fodder without any supplement, the diet for the 1st experimental group included 4.0% CPhFA, the 2nd – 6.0%. The obtained results indicate that the inclusion of the studied complex phytobiotic feed additive in the diets for young quails contributes to the increase in live weight of birds: by 2.0% – according to the 1st experimental group, by 0.7% – according to the 2nd group. Poultry of the experimental groups consumed 14.6% less feed during the experiment compared to the control index (807.0 g/head). At the same time, feed costs per 1 kg of live weight gain in the 1st and 2nd experimental groups decreased by 16.9 and 15.3%, respectively, relative to the control. The analysis of economic efficiency indicates a decrease in the cost of production in the experimental groups by 7.3 and 6.0% compared to the control. It was found that feeding meat quails with 4.0 and 6.0% by feed weight of the studied complex phytobiotic feed additive increased profitability by 8.6 and 6.9%, respectively, relative to the control.
