Morphological parameters quail's eggs when feeding organic concentrate

One of the main factors that ensure the growth of profitability of poultry farming is the partial replacement of grain crops with non-traditional feed with low cost, which, for example, can be considered processed dry bird droppings (SPP). The aim of the research was to study the effect of organic concentrate based on SPP on the morphological parameters of quail eggs. For the study, 5 experimental groups of quails were selected using the method of analog pairs. The birds of the control group received factory-made feed DC-52-100 %, the quails of the experimental groups (I, II, III and IV) were replaced by 10, 15, 20 and 25% by weight, respectively, with an organic protein concentrate based on SPP. In studies, it was found that the introduction of an organic concentrate based on SPP in the amount of 10, 15, 20, 25 % instead of a similar amount of mixed feed contributed to an increase in the relative weight of the yolk by 1,55; 4,51 (P
