Functional additive based on natural premix in the diet of quails

Abstract

The results of the experiment on the use of functional additive in the diet of growing quails on the basis of natural organomineral complex (sapropel) enriched with wheat bran, coniferous flour, pine nut shells and enzyme preparation Fitbest WP are presented. The experiment lasting 60 days was conducted according to the standard methodology on Japanese quails. For the experiment, two similar groups of 60 birds each (one control and one experimental group) were formed at one day of age. Both groups received basic mixed fodder corresponding to the physiological characteristics and age of the quails. In the ration of young animals of the experimental group 10% of the wheat mass was replaced by a functional additive consisting of sapropel (50%), wheat bran (20%), coniferous flour (15%) and pine nutshells (15%), enriched with the enzyme preparation Fitbest WP (100 g/t mixed fodder) designed to increase the absorption of phytate phosphorus. The birds were kept in a cage battery under the required microclimate conditions. The effect of feeding the experimental additive on the following indicators of quail chickens was studied: safety, average daily gain of live weight, meat productivity and meat quality, biochemical composition of blood. Introduction of the functional additive on the basis of natural premix (sapropel) into the mixed fodder of quails increased the safety of birds by 2.00%, live weight gain by 6.97% with no significant differences in the consumption of mixed fodder per unit production. The meat of the poultry that consumed the functional additive increased the dry matter content by 0.85%, ash by 0.61%, calcium and phosphorus by 1.05 and 1.30 times (p < 0.05). Intergroup differences in protein content and fat content were insignificant. Hematological parameters of quail chickens in the experimental groups corresponded to the physiological norm.
