Efficiency of feed utilization and growth of repair young quails with the use of a phytobiotic supplement

Phytobiotics are an effective and natural way to combat the problem of antibiotic resistance in animal husbandry, which ensures the safety of consumed products, making them an important tool in poultry farming. The aim of the research work was to study the effect of phytobiotic supplement on live weight, growth and feed consumption in young quails. The experiment for repair young quails lasted 35 days. For the experiment, 4 groups of day-old quails of the “Manchurian Golden” breed were selected according to the principle of similar groups, 50 heads in each group. The quails of the control group were fed the basic ration – complete ration granulated compound feed. In addition to the main diet, the birds of the experimental groups consumed different doses of the phytobiotic supplement. The composition of the phytobiotic contains dried, crushed and granulated plant ingredients and natural extracts of the Macleaya cordatas plant. It was established that the additional consumption of phytobiotic supplement increases the live weight of quails in the 2nd group by 5.6 % (Р < 0.01), the 3rd by 8.6 % (Р < 0.001) and the 4th by 14.0 % (P < 0.001), against control peers. It was found that the use of the studied phytobiotic increased absolute live weight gains in the 2nd group by 5.8 % (Р < 0.01), in the 3rd group by 8.8 % (Р < 0.001), and in the 4th group by 14.5 % (Р < 0.001) compared to the control group. The additional use of a plant feed additive increases the average daily growth in the 2nd group by 5.7 % (Р < 0.05), in the 3rd group by 8.9 % (Р < 0.01), and in the 4th group by 14 .4 % (Р < 0.001), against the control indicator. It should be noted that with the addition of a phytobiotic additive to the combined feed of quails, the relative increase is greater in the 2nd group by 0.8 % (Р < 0.01) than in the 3rd group by 0.8 % (Р < 0.01), and in 4th by 1.5 % (Р < 0.001) than in the control. It was found that the consumption of feed per 1 kg of live weight gain was 10.0 % lower in quails of the 4th group, compared to the control.
