摘要

摘要提高家禽的生产率是确保完成 "粮食安全理论 "任务的一个重要问题。这项工作的目的是研究在肉鸡养殖过程中使用 Ares 生物技术添加剂(膳食补充剂)对体重增长的有效性,同时考虑到性别因素。方法。在乌拉尔国立农业大学教育和实验农场家禽车间的条件下,对 Kobb 500 杂交家禽进行了科学和生产体验。体验期为 38 天。我们研究了肉鸡在生长方面的生产率与杂交标准要求的比较,具体取决于性别。活重是通过随机抽样(每种性别各 5 头)在每个分组中称重 10 头来确定的。结果无论哪个组别,所有鸡的活重都随着日龄的增加而增加,到培育结束时达到 2632-2880 克,符合杂交标准的要求。活重最高的是第二实验组,该组使用了干饲料添加剂 "阿瑞斯",每吨配合饲料添加 300 克(P ≤ 0.05)。在所有实验组中,研究结束时,鸡的活重均低于公鸡。第二实验组的差异显著(P ≤ 0.05;对照组和第一实验组的差异显著(P ≤ 0.01,公鸡更优))。在 P ≤ 0.01 和 P ≤ 0.05 时,第二实验组的鸡在活重方面明显优于其他组。在公鸡中,第二实验组在研究期间达到最大活重的效果最好,该组使用的 "Ares "生物技术添加剂为干物质,剂量为 300 克/吨。这项工作的科学新颖性在于,研究是在肉鸡性别的背景下进行的,在使用生物技术药物 "阿瑞斯 "时,获得了不同性别鸡的生长强度参考指标。

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