Description
The researches were carried out with the support of the Federal state budget establishment "The development assistance fund of small forms enterprises in scientific-technical sphere" (Fund for the innovation promotion), contract number 0019671. The fodder additive «Nutovit» in growing chickens feeding application enriched mixed fodder for farm poultry with protein and especially with the amino acid such as lysine. Scientific-economic experiment was carried out at the poultry-farm enterprise of the Volgograd region in 2015-2016. 4 growing chicken groups with 54 heads in each group were selected for the experiment. The growing chickens were selected according to the cross, age, living body weight, health status. The difference in experimental poultries feeding was that in the experimental groups the sunflower oil cake in the feed mixture was replaced by fodder additive "Nutovit". It was established, that the essential amino acids availability and the saturation of fodder additives with vitamins influence positively on: young chickens live weight and average daily growth, the live weight to 120-days age in the second experimental group amounted to 1657 g, and average daily growth was to 12.46 g, which is higher compared to the control group by 4.48 % at 100% poultry livability; blood morphological and biochemical composition: formed elements of blood, namely erythrocytes, in the experimental groups young chickens blood were more in 0.02 to 0.05×1012/l compared with the control one. The researches established that blood leukocytes reduction in growing chickens of the experimental group was little, in 0.04, 0.09, 0.08 ×109 l. Calcium content in growing chickens blood in the control group was 2.6 mmol/L. The experimental group surpassed the control on 0.14-0.21 mmol/L. The phosphorus content in chickens blood in the experimental groups exceeded the control one by 0.08-0.24 mmol/l. In addition, the feeding cost reduction was established due to the fodder additive "Nutovit" use

Description
This article presents the studying results of new premixes of domestic production using efficiency based on processed products, in particular - oil cakes. The research was carried out in the conditions of the second-order pedigree reproductor in LLC "Svetly" in the Svetloyarsky district of the Volgograd region in the period from 2015 to 2017. During the scientific and economic experience, the authors revealed the new fodder additives positive influence on the laying hens’ egg productivity, on the eggs morphological and incubation rates and on the got young birds. The use of premixes in layer diet, which included the fodder concentrate from the plant raw material "Sarepta" and Camelina seed oil cake, contributed to the increase in the hens laying capacity, in general, the group received in 249 and 310 pieces more than in the control one. The egg average weight from the chickens of the control group was 60.89 g; from the first experimental it was 61.33 g; from the second experimental it was 61.39 g, which was higher than in the control one, respectively, by 0.44 g and 0.50 g. While the hatching eggs morphological indices analysis, it was revealed that all parameters are within the permissible limits of the physiological norm. Fertilization of eggs in the control group was at the level of 89.33%, which is lower than in the experimental groups. As a whole, the eggs' production in groups was 20.00% in the control, 17.33% in the 1st group, and 16.00% in the 2nd test group
