The usage of biologically active additives in animal diets provides maximum use of nutrients, it has a positive effect on digestion. Therefore, it contributes to the rational and economical use of feed, it increases its productivity, and livestock farming becomes economically feasible. It has been proved that using dry extract of Echinacea pallida for the feeding quails of meat breed Pharaoh helps to increase protein accumulation and reduce fat loss in the chest muscles.
The aim of the study was to research the physical and chemical parameters of the quails meat of the Pharaoh breed. To accomplish this goal an experiment was carried out on quails of the Pharaoh meat breed in accordance with generally accepted methods. Forming poultry groups, we took into account the live weight, age, sex, breed, productivity, conditions of maintenance and feeding. According to the research results, it was found that feeding quails by the extract of Echinacea pallida increases the percentage of dry matter in white meat of quails by 0.51% (P<0.001), the protein content is increased by 3.46% (P<0.001), the amount of fat is increased by 1.27% (P<0.001) compared with the control group. The use of phytobiotics for poultry feeding increases the level of dry matter in the femoral muscles by 0.25% (P<0.01), fat by 4.05%, and extractives without nitrogen by 1.72% (P<0.001) compared with benchmark. The additional consumption of the phytobiotic additive increases the content of phosphorus by 10.7% (P<0.001), calcium by 0.51 g per kg (P<0.001), manganese by 44.8% (P<0.01) and copper by 7.3 mg per kg (P<0.001) in the quails pectoral muscles compared with the first control group. The content of calcium increased by 22.4% (P<0.001), iron by 55.7% (P<0.001), zinc by 50.1% (P<0.001), manganese by 68.9% (P<0.001) and copper by 3.27 mg per kg (P<0.001) under the action of Echinacea pallida extract in the femur of the bird, relative to the control sample.
