Abstract
Experiments were carried out to study the possibility of increasing the productivity level of quails by feeding a new probiotic feed additive based on microorganisms of the genus Enterococcus. The work was carried out in 2022 on Phoenix quails. From the age of one day, in addition to the main diet, the birds of the experimental group daily received a suspension culture of Enterococcus faecium ICIS 96 with a cell concentration of 1 × 109 in 1 mL at the rate of 0.1 mL per 1 kg of live weight. To achieve this goal, a scientific and economic experiment was carried out. At the first stage, the influence of the Enterococcus faecium ICIS 96 strain on the growth, development, and meat productivity of quails up to 42 days was determined, and at the second stage on the egg productivity of quails. The live weight of quail in the experimental group was higher than in the control group at all age periods: on the 28th day by 19.4 g, or 15.02%, on the 42nd day by 23.8 g, or 9.0%. The weight of gutted quail carcasses, which received in addition to the main diet a suspension of Enterococcus faecium ICIS 96 culture, was greater than in the control by 25.42%, half-gutted by 25.33%, and slaughter yield by 8.9%. The highest egg production during the productive period (30 weeks) was observed in quails of the experimental group: the gross collection of eggs was 5365 pcs, which was 701 pcs more than in the control group. At the same time, the thickness of their shell was 8.6% higher. As a result, revenue from the sale of eggs was higher by 4429.2 rubles, and the level of profitability by 4.5%.
