The effectiveness of the use of biotechnological additives in the cultivation of broiler chickens

Abstract

Abstract. Increasing the productivity of poultry, an important issue of ensuring the fulfillment of tasks under the Doctrine of Food Security. The purpose of the work was to study the effectiveness of the use of Ares biotechnological additive (dietary supplement) in the cultivation of broiler chickens for their weight growth, taking into account gender. Methods. Scientific and production experience was carried out in the conditions of the poultry workshop of the educational and experimental farm of the Ural State Agrarian University on the poultry of the Kobb 500 cross. The duration of the experience is 38 days. We studied the productivity of broiler chickens in terms of growth in comparison with the requirements of the cross standard, depending on gender. The live weight was determined by weighing 10 heads in each subgroup, selected by random sampling (5 heads of each sex). Results. All chickens, regardless of the group, increased their live weight with age, reaching 2632–2880 g by the end of cultivation, which meets the requirements of the cross standard. The highest live weight was obtained in the 2nd experimental group, where dietary supplements “Ares” were used in dry form in the amount of 300 g per 1 ton of compound feed (P ≤ 0.05). In all experimental groups, chickens were inferior to cockerels in terms of live weight at the end of the studies. The difference was significant at (P ≤ 0.05, 2nd experimental group; P ≤ 0.01, control and 1st experimental group, in favor of cockerels). Chickens from the 2nd experimental group significantly outperformed chickens from other groups in live weight at P ≤ 0.01 and P ≤ 0.05. Among the cockerels, the best results in achieving the maximum live weight during the research period were also achieved in the second experimental group, where the “Ares” biotechnological additive was used in dry form at a dose of 300 g/t. The scientific novelty of the work is determined by the fact that studies have been conducted in the context of the sex of broiler chickens and reference indicators of growth intensity in chickens of different sexes have been obtained when using the biotechnological drug “Ares”.
