This paper presents the results of studying the conversion of feed into nutrients in the carcass of bulls during the fattening of young Kalmyk breed in the conditions of Yakutia. The studies were carried out on the basis of the Soloosun agricultural production complex, Megino-Kangalassky region. The experiment was organized on Kalmyk bull-calves fed from 15 to 18 months of age. There were formed 2 groups of 25 bulls analogs: the control and the experimental one. The animals of the control group were fed according to the ration adopted on the farm. The diet of the animals from the experimental group included 200 g of Hongurin zeolite and 45 g of Kempendyai salt per animal. The main ration of animals by structure consisted of meadow hay 46%, haylage – 22% and compound feed 32% or 12.57 EFU per day. At the beginning of the experiment, the live weight of the animals was almost identical. At the end of fattening, the bulls of the experimental group in live weight exceeded the animals of the control group by 10.9 kg. Consequently, the experienced bulls had higher bioconversion rates, which was reflected in an increase in the meat productivity of animals. The analysis showed that the control group of bulls was inferior to the experimental group in terms of pulp by 11 kg., In the deposition of food protein by 1.3 kg. The calculation of the data on the conversion of protein into food protein showed that in the control group this indicator is 5%, and in the experimental group it was 6.2%. The yield of dietary protein in the control group was 40.4 g, in the experimental group – 52.8 g. Thus, the calculation of bioconversion showed that the animals of the experimental groups, which additionally consumed Hongurin zeolite and Kempendyai salt, had a higher ability to transfer nutrients and feed energy into meat products. The indicators of economic efficiency per 100 heads of fattening bulls of the Kalmyk breed are: profitability – 122.53%, cost price 1132 thousand rubles, profit – 1,388 thousand rubles, profit – 1.23 rubles per 1 ruble costs. The efficiency of beef production at a specialized feedlot increases by 22.53%.

The article presents the results of studies of the bioconversion of nutrients and feed energy into meat products when fattening young Kalmyk breed in Yakutia. The studies were carried out on the basis of the SCHPK Soloyun Megino-Kangalassky region. The experiment was organized on Kalmyk gobies fed from 17 to 18 months of age. For the experiments, 2 groups of animals were formed, which were divided into control and experimental groups. The control group consumed the main diet, the experimental group additionally consumed 200 g of Suntarsky zeolite per head. The main diet of animals by structure consisted of meadow hay 46%, haylage – 22% and mixed fodder 32% or 11.95 ECU per day. During the experiment, the live weight of the animals was almost identical. At the end of fattening, the animals of the control group yielded to the bulls of the experimental group by 3.5%. It was found that the gobies of the experimental group had higher indicators of meat productivity, which affected bioconversion. The analysis showed that the control group of bulls yielded to the experimental group in terms of pulp by 26.9%, in the deposition of food protein by 13.6%. The conversion rate of protein into food protein in the control group was 12.0%, and in the experimental group the indicator was 21.3%. The yield of dietary protein in the control group was 8.08 g, which is 33.6% less than in the experimental group. Thus, the calculation of bioconversion showed that the animals of the experimental groups, which additionally consumed Suntarsky zeolite, had a higher ability to transform nutrients and feed energy into meat products.

Abstract The paper presents the results of fattening young cattle in the conditions of Yakutia with the use of complex feed additives from local natural raw materials in their diets. One of the ways to increase the meat productivity of livestock is to optimize feeding by inserting complex feed additives into their diets. Therefore, studies were conducted to determine the effectiveness of complex feed additives in the fattening of young cattle in the conditions of Yakutia. At the beginning of the experiment, the live weight of the animals in the groups did not differ much, but starting from the age of 12 months, the superiority of the animals from the experimental groups is noted. In the period of 12-15 months of age, the animals from the experimental groups exceeded the growth rate of the control group by 6.70% and 4.76%. In the period of 15-18 months old, the animals of the control group were inferior to the experimental groups by 28.31% and 16.54%. On average, the animals of the experimental groups grew more intensively in comparison with the control group by 12.73% and 8.66 %. Analysis of animal slaughter data showed that the experimental groups were superior to the control group in a number of indicators, such as the mass of the steam carcass by 8.04% and 4.43 %, the mass of visceral fat by 18.59% and 7.39%. The organoleptic evaluation of meat products also confirmed the superiority of the experimental groups over the control group. Thus, the use of complex feed additives in the feeding of young cattle on fattening showed its effectiveness.

The purpose of the work was to study the influence of protein-vitamin-mineral additive and protein-vitamin-mineral concentrate on the growth, development and meat productivity of steers. Studies have been carried out on the rearing of steers when using the protein-vitamin-mineral additive based on extruded soybean with bentonite in the preweaning period and the protein-vitamin-mineral concentrate (with urea concentrate) when fattening steers. During the first research and production experiment in the calves of the 1st experimental group 30 % and in the bovine calves of the 2nd experimental group 40 % milk replacer have been replaced with a protein-mineral-vitamin additive. At the beginning of the experiment the calves of all groups had almost the same live weight. Starting from the age of 1,5 months the growth of the animals of the experimental groups began to prevail over the control group. Thus, the bull calves of the 1st experimental group at 2 months of age were larger than the control ones by 5,1 %, by the end of the experiment their superiority was 7,6 % (P < 0,01). The total gain in live weight of the bull calves of the 2nd experimental group was 9,4 % higher (P < 0,001) than in the control group. During the second research and production experiment on the use of protein-vitamin-mineral concentrate the difference in feeding was that the steers of the experimental group consumed complete feed, which included protein-vitamin-mineral concentrate (with urea concentrate) and bentonite. The gain in live weight of calves for 5 months of experiment in the control group was 136,7 kg, and in the experimental group it was 11,4 % more. The expenditures of feed per 1 kg of gain in EFU were by 10,1 % lower in the experimental group compared to the control group. The level of profitability of beef production in the control group was 16,1 %, and in the experimental group it was 26,5 %, which was more by 10,4 abs.%.

The article presents the results of bulls control slaughter, morphological and varietal composition of the pulp of carcasses, depending on the duration of the production cycle and the level of concentrates in the diet. In the gobies of the control group, the total duration of the production cycle was 18 months (546 days), with a specific gravity of concentrates in the rations of 40 % in the experimental group – 16 months (482 days) – 50 %. The suckling period of calves in the control group was 210 days, in the experimental group – 182 days, rearing – 186 and 165 days, respectively, intensive final fattening – 150 and 135 days. The differences obtained both in the pre-slaughter live weight and in the weight of the paired carcass were 1,9 and 3,4 kg, respectively, without a significant difference between the groups. The superiority of bulls of the experimental group over the control group was established according to the leading studied indicators of the morphological composition of carcasses, except the mass of bones, cartilage, and tendons. Differences in the mass of the pulp in favor of the calves of the experimental group were 5,1 kg, the coefficient of meat content was 0,21 units, the ratio of the edible part to the inedible part in the carcass was 0,26 units. All other things being equal, from the bulls of the experimental group, a higher mass of pulp of the highest grade was obtained by 4,9 kg or 2,2 %, of the first grade – by 6,4 kg or 1,8 %. The yield of secondgrade pulp was higher in the carcasses of gobies of the control group by an average of 6,2 kg or 4 %. Thus, both groups of bulls showed high slaughter weight and slaughter yield, with insignificant intergroup differences. However, due to the shorter duration of the production cycle of growing and fattening, it turned out to be preferable to use beef production technology from bull calves of the experimental group.

Animals imported to Yakutia from other regions fall into feeding and housing conditions that differ from their usual agro-climatic conditions, which causes the problem of their adaptation. Yakutia is one of the areas where the feed of its own production has a lack of basic minerals, which affects the health and productivity of animals, which has an additional negative influence on the adaptation process of imported cattle. In order to replenish macro- and microelements in the body, it is necessary to introduce various local mineral feed additives, premixes, and use mineral salts into the ration. Under the conditions of Central Yakutia the influence of local mineral feed additives (zeolite of the Khonguruu Deposit in the Suntar district and sapropels of local lakes) containing macro- and microelements that increase the meat productivity of steers has been studied. As a result of the research the influence of local mineral feed additives on meat productivity and physiological condition of Hereford steers has been established. Influence of zeolite and sapropel in a complex with mineral salts on digestibility of nutrients of the ration and use of nitrogen, calcium and phosphorus by experimental animals has been defined. The influence of feed additives on the quality of meat products has been studied. The results have shown that the use of local mineral feed additives in the composition of ration of steers during the fattening period at a dose of 0,7 g zeolite per 1 kg of live weight of the animal and 200 g of sapropel in combination with 10 g of mineral salts contributed to the gain in live weight, carcass weight, carcass yield, yield of edible parts, and economic efficiency of fattening. For the entire period of the experiment the gain in live weight in groups was: in control group 2222,9 kg, in the 1st experimental group 2396,2 kg, in the 2nd experimental group 2471,1 kg. The total economic effect for the 1st experimental group for the period of experiment amounted to 44,3 thousand Rubles, for the 2nd experimental group 78,0 thousand Rubles or per 1 head/day 14,06 and 24,76 Rubles, respectively.

Preparations of highly dispersed particles of trace elements are increasingly used in animal husbandry. This is determined by their extraordinary biological properties such as the ability to penetrate into tissues and organs, a high surface area, and so on. One of the promising directions for using highly dispersed particles both in the post-embryonic and embryonic periods of animal development is the use of trace elements as sources. This is determined by the relatively lower toxicity, higher bioavailability of elements from preparations of highly dispersed particles, which reduces the load on the environment and allows you to produce products enriched with minerals. The purpose of the research was to study the effect of highly dispersed drugs on rumen digestion, the composition of the rumen microbiome, metabolism and productivity of young cattle. A comprehensive assessment of the use of highly dispersed SiO2 and FeCo preparations in cattle nutrition has been provided in the paper. The digestibility of feed, metabolism, and productivity of young cattle when feeding highly dispersed particles have been studied. An unusual fact of increasing bacterial biomass when using highly dispersed particles of silicon dioxide in animal feeding has been described. A method for increasing the digestibility of feed components by ruminants through the use of highly dispersed FeCo alloy particles has been proposed. As follows from the data obtained the use of highly dispersed particles allowed to increase the live weight of experimental young animals to 413 kg in the 1st experimental group and 416 kg in the 2nd experimental group, which was by 11 (P ≤ 0,01) and 14 kg (P ≤ 0,01) higher than the control indicator. As follows from the analysis of the data obtained, the profitability of rearing young animals in the 1st and 2nd experimental groups was by 2,4 and 2,2 % higher than the same indicator calculated for the control group.

Abstract. The purpose of the research was to develop a method for increasing the meat productivity of sheep under various housing systems. Methods. All studies were conducted according to generally accepted methods. The experimental population of rams of the control and experimental groups was kept until the age of 3 months together with ewes on the pasture (suckling period) with further weaning at the age of 3 months. Further, the rams were divided according to the technologies of keeping: the control group – pasture (graziery), and the experimental group – indoor maintenance (fattening) up to 4 months of age, followed by control slaughter. Monthly weighing of the experimental young rams livestock was carried out. Results. The research work showed that the use of this technological method significantly contributed in increasing average gain and live weight, respectively, by 6.6 % (20 g) and 5.7 % (2.3 kg) and as a result, slaughter weight – by 9.2 % (1.6 kg) in young rams from the experimental group in comparison with analogues of the control group. Chemical, amino acid and microstructural analyses of samples of the longissimus of the livestock showed that the specimens of the young rams of the experimental group had the best food and market advantages. The efficiency of using this technological method is also confirmed by the calculated economic indicators – the difference in the level of profitability was 7.9 % in favor of the rams of the experimental group. The scientific novelty of the research work is a detailed study of the indicators of meat productivity under the influence of this technological method with the justification of its application and the introduction of both scientific and practical contributions to the development of sheep farming.

Статья отражает исследования по применению свежей пивной дробины в кормлении бычков на заключительном этапе откорма и сухой пивной дробины при выращивании ремонтных телок в возрасте 6-12 месяцев, которые показали ее положительное влияние на качество кормовых рационов и продуктивность животных. В основном рационе контрольных групп часть комбикорма заменяли пивной дробиной: при откорме бычков – 5 кг свежей дробины взамен 1 кг комбикорма, при выращивании телок – 0,5 кг сухой дробины взамен аналогичного количества комбикорма. За счет применения пивной дробины была повышена протеиновая ценность рационов и оптимизирован их микроминеральный состав, что способствовало активизации обмена веществ в организме животных и повышению их продуктивности. У бычков опытной группы живая масса в конце откорма и среднесуточный прирост были, соответственно, выше на 2,5 % и 7,4 %, нежели у контрольных животных. Данные показатели у телочек опытной группы были выше контрольных значений на 4,1 и 6,5 % соответственно. Затраты энергетических кормовых единиц на 1 кг прироста живой массы у животных опытных групп были ниже на 7,3-7,6 % в сравнении с контролем. Установлена экономическая целесообразность применения свежей и сухой пивной дробины в рационах молодняка крупного рогатого скота, так как за счет повышения интенсивности роста животных и значительной экономии зерновых кормов себестоимость 1 кг прироста живой массы, полученного на рационах с дробиной, была ниже на 6,2 % у телочек и на 10,4 % у бычков. The article reflects studies on the use of fresh spent grain when feeding bulls at the final stage of fattening and dry spent grain when growing replacement heifers aged 6-12 months, which showed its positive effect on the quality of feed rations and animal productivity. Part of the mixed fodder in the main diet of the control groups was replaced with spent grain. Bull calves got 5 kg of fresh spent grain instead of 1 kg of the mixed fodder and heifers got 0.5 kg of dry spent grain instead of the same amount of the mixed fodder. Thanks to pent grain, the protein value of diets was increased and their micro mineral composition was optimized, which contributed to the activation of metabolism in animals and increased their productivity. The live weight of the bulls of the experimental group at the end of the fattening was 2.5% higher than that in the control animals and the average daily gain was 7.4% higher. These indicators in the heifers of the experimental group were higher than the control values by 4.1% and 6.5%, respectively. The cost of energy feed units per 1 kg of increase in live weight in animals of the experimental groups was lower by 7.3-7.6%, compared with the control. The economic feasibility of using fresh and dry spent grain in the diets of young cattle was established, since due to an increase in the growth rate of animals and significant savings in grain feed, the cost of 1 kg of live weight gain obtained from rations with spent grain was 6.2% lower in heifers and 10.4% in bulls.

One of the most effective ways of removing HM salts that have entered the digestive tract of fattened animals is the technological method of including adsorbent preparations in their diets, which, binding various toxins, excrete them from the body. The study purpose is to develop a method to increase the meat productivity and quality of meat of young cattle for fattening in a technogenic zone by inclusion of ToxySorb adsorbent in their diets with a high content of heavy metal salts in the amount of 1.25 kg/t of compound feed and lecithin in the amount of 10 g/100 kg of live weight. According to study results, it was shown that when these drugs were fed together in the indicated quantities, it contributed to better detoxification of xenobiotics. The calf bulls of experimental group 3 had the best slaughter indicators, as well as the best consumer, sanitary and hygienic properties of meat products.
