This article presents the results of the chick peas use instead of sunflower cake, in feeding young and adult livestock hens-layers of the cross "Hajseks brown". The researches were carried out in the JSC "Agrofirm Vostok" of the Nikolayevskiy district in the Volgograd region. The sunflower cake replacement with legumes - chickpeas as the part of the experimental animal fodder for young and adult livestock hens-layers had a positive influence on productivity, physiological state of the birds, product quality and economic performance. Chick peas’ use in young hens feeding improves live weight at 1.03-4.68%, egg production in 0.99-4.7%, the average weight in 0.99-3.75% and eggs quality indicators. Morphological and biochemical indices in experimental young hens and laying hens in all the groups were within the physiological range, indicating normally occurring redox processes in the body of a bird. However, the chick peas’ application in fodder for experimental young hens and laying hens contributed to the increase of total protein, calcium, phosphorus content in serum compared with counterparts in the control group that received sunflower cake. As the researches result, the economic effect in the experimental groups was 833.01-3821.87 rubles

This article presents the results of the chickpea effect in feeding young and adult laying hens of "Hajseks brown" cross on their productivity and nutrient digestibility of feed. Studies have been conducted on the JSC "Agro-firm Vostok" in Nikolayevsky district of the Volgograd region. Complete or partial replacement of sunflower oil cake by chickpeas as part of feed for the experimental pullet hens improves nutrient digestibility coefficients compared with the control pullet group. The balance of nitrogen was positive in all groups, the use of nitrogen taken from guinea pullets was higher than in the control group at 0, 27-0,74%. Use of chickpea in the composition of feed for laying hens increases the digestibility coefficients of nutrients: dry matter - to 1,17-3,25%, organic matter - to 1,62-3,37% crude protein - to 0,45-1, 77%, crude fiber - to 0,72-1,05%; crude fat - to 0,35-1,55%, compared with chickens, hens in the control group. The use of nitrogen from the digested was1,37-2,13% higher in the experimental groups compared to analogs of the control group. The use of calcium and phosphorus for the formation of eggs was also higher in the experimental groups

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

The right balance of essential amino acids and protein is the main condition for the optimization of weight gain, feed conversion and high profits. In VGC "Megamix" the quality of different types of raw full-fat soy, wheat, corn, meat and bone meal and fish was assessed on the content of amino acids on the IR analyzer of FOSSNIR Systems company. Amino acid content in the feed does not always match the average standards of reference. So in the reference data content of methionine, threonine and phenylalanine in wheat, indicated 0.23%, 0.43% and 0.64% respectively, and studied in the laboratory of VGC "Megamix", respectively, 0.24%, 0.45% and 0 73%, that is 0.01%, 0.02% and 0.09% higher of tabular values. The lysine content of the wheat to be investigated in a laboratory and provided in the averaged data was on the same level. Thus, the calculation of the recipes should be carried out taking into account not tabulated values but the actual, which will reduce the so-called "safety stock" to get food of consistent quality and reduce the cost of the cost of animal feed, which in turn affects the economic efficiency of livestock production

Different liquorice’s dosage as additive to main diet influence on chicken-broilers quality and productivity is studied in the article. According to the results, it was established that liquorice addition use in chicken-broilers’ fattening diet during 42 days provided chick-en-broilers gain increase and fodder consumption decrease per 1 kg of the gain increasing, therefore, production economic efficiency

The article presents the data of liquorice fodder addi-tive use in chicken-broilers diet

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
