In the practice of feeding poultry enzyme drugs are widely used that contribute to the effective transformation of feed components into poultry products. Reducing the cost of compound feed for poultry due to the introduction of enzyme drugs is of great interest, both from a scientific and practical point of view. More than 2/3 of phosphorus in plant feeds is represented in the form of phytate and in this form the element is only partially absorbed in the poultry body. Accordingly to cover the need for phosphorus in plant diets include inorganic phosphates, animal feed and the enzyme phytase (breaks down phytate). This makes phosphorus the third most expensive feed component after energy and protein. The purpose of the researches was to study the effectiveness of using super dose commercial phytase in feeding of turkey poults. The results of research on the use of high doses of phytase in the diet of turkey poults of cross Hybrid Converter have been presented. It has been found that the use of compound feeds containing the super dose of phytase in the rearing of broiler turkey poults does not have a negative influence on the zootechnical indicators of poultry rearing, meat productivity, and increases the economic indicators of meat production. The results on base the experiment, economic indicators have been calculated. It has been found that the cost of 1 ton of compound feed consumed in the experimental group was less than in the control group by 166,28 rubles or 0,7 %. The use of high doses of phytase in the diet of turkey poults of the experimental group allowed to reduce the cost of growth of 1 kg of live weight by 4,7 % and increase the profitability of meat production.
The study of the use of compound feed with shelled and unshelled sunflower seeds in the rearing of broiler chickens is of scientific and practical interest. The purpose of the research was to assess the influence of the inclusion of sunflower kernels and seeds in compound feed on the productivity of broiler chickens. In accordance with the set purpose and objectives of the research the experiment has been carried out on broiler chickens of the Arbor Acres cross from the daily age to the 35-day age under the conditions of the LLC “Morozovskaya Poultry Farm”. For the experiment, 5 groups of broiler chickens with 100 heads in each have been formed. The planting density, light and temperature conditions corresponded to the recommendations for growing broilers of this cross. The broilers of the control group have been received the main diet, and the poultry of the experimental groups have been received compound feed with kernels (5,0–7,5 %) and seeds (5,0–7,5 % + the enzyme drug Ronozyme VP 250 g/t) of sunflower. The results of studies on the inclusion of sunflower kernels and seeds in the diets of broiler chickens have been presented in the article. Data on zootechnical indicators of rearing, results of slaughter and anatomical cutting of carcasses, as well as economic indicators of meat production have been presented. The livability of broiler chickens both in the control and in the experimental groups was at a high level and did not depend on the inclusion of the tested ingredients in the compound feed. It has been found that the inclusion of both 5–7,5 % of sunflower kernels and 5–7,5 % of sunflower seeds with husk in the diet of broiler chickens in combination with the enzyme preparation Ronozyme (250 g/t) contributes to increasing the productivity of poultry, reducing the cost of compound feed, which allows increasing the level of profitability of meat production by 1,9–3,2 %.
In Russian market of meat products production of poultry meat occupies more than 47 %. At the same time, the share of poultry products in the total volume of animal protein consumed is 42,1 %, including poultry meat – 27,8 %, eggs – 14,3 %. The quality of the resulting meat is significantly influenced by feeding (feed ingredients, biologically active additives). The purpose of the investigations was to study the influence of compound feed containing Camelina presscake on the chemical composition of broiler muscle tissue. The investigations have been carried out on the basis of the Siberian Scientific and Research Institute of Poultry Farming – a branch of the Federal State Budgetary Scientific Institution “Omsk Agricultural Research Center” (Morozovka village, Omsk region) on broiler chickens of the cross Sibiryak-2. The results of the investigations on the influence of compound feed with Camelina presscake obtained from seeds of the Siberian selection on the qualitative composition of the muscle tissue of broilers have been presented in the article. The research has been conducted on four groups of broiler chickens from 1 to 42 days of age, in each group there were 100 heads. Camelina presscake was introduced instead of another traditional protein feed to the 1st experimental group – 12,5 %, the 2nd – 15 % and the 3rd experimental group – 20 % with the preservation of the total energy and protein nutrition of the compound feed. It has been found that in the muscles of broiler chickens of the experimental groups the protein content was higher by 0,06–0,73 abs.%, fat by 0,03–0,57 abs.%, energy nutrition higher by 0,03–0,29 MJ/kg. When comparing the amount of macro- and microelements in muscle tissue, the advantage has been noted for most of the studied indicators of poultry of experimental groups that received compound feed with Camelina presscake.
