Abstract:The paper shows the impact of the M-feed new generation feed additive in the quail diets on their growth energy, the quality of the egg and the biochemistry of the laying quails. It has been established that of the three feed additive dosages under study the daily dosage of 200 mg/100 g of the combined feed provides the most favorable conditions for the organism of the test quails. This, in turn, contributes to a reduction in feed costs, an increase in growth energy by 7.9%, an improvement in the quality of the eggs. In the test quails who received such quantity of M-feed, the mass of eggs and protein in them was higher than that in the control analogs by 1.7 g. At the same time, the protein index increased by 11.45, the yolk -by 2.1% and the number of carotenoids -by 13.6%. The analyses also showed that the addition of M-feed in the combined feed in such an amount contributed to the improvement of the mineral composition of eggs and the resistance of quails.
