Complex phytobiotic feed additive in diets for quail grown for meat

The purpose of research is to study the effectiveness of including a complex phytobiotic feed additive (CPFA) in diets for quail raised for meat. In the conditions of the vivarium of the Federal State Budgetary Scientific Institution Krasnodar Research Centre for Animal Husbandry and Veterinary Medicine, a scientific experiment was conducted on quails of the Texas breed. From day-old chicks, 3 groups of 35 heads each were formed using the pair-analog method. The experimental poultry were kept in the same conditions with free access to food and water. The duration of the experiment was 31 days. As a result of a scientific experiment, it was established that the inclusion of a complex phytobiotic feed additive in diets for the second group in an amount of 1.0 % of the feed weight contributes to a significant (P ≤ 0.05) increase in the level of live weight by 0.2 % compared to the control. Over the entire period of the experiment, the use of feed additives in poultry diets in amounts of 1.0 and 2.0 % contributed to a decrease in average daily feed consumption by 11.9 and 14.6 %, respectively. Along with this, feed costs per 1 kg of live weight gain decreased by 17.2 and 24.1 %, respectively. In the third experimental group, the weight of the muscular stomach with contents increased significantly (P ≤ 0.05) by 26.8 %, without contents - by 36.8 % (P ≤ 0.01). In the second group, which received 1.0 % of the weight of the feed CPFA, the level of internal fat content significantly decreased by 50.0% compared to the control. The use of the studied supplement contributed to an increase in the level of protein content in the muscles of the experimental groups by 4.57 and 2.91 %. The inclusion of a phytobiotic additive in diets for meat quails in amounts of 1.0 and 2.0 % of the feed weight contributed to an increase in profitability by 4.7 and 7.1 %, respectively.
