As a result of the researchers found a positive effect of new feed additive on the growth rate, the qualitative indicators of meat fattening. It was found that the effect of feed additives on the productivity increased with increasing doses of feed additives from 100 to 300 g per head. Thus, at the age of 18 months, the bulls of the first experimental group surpassed the control analogues by 3.86, the second – by 5.53 and the third – by 6.42% and the average daily increase by 7.50, 11.63 and 12.45%, respectively. On the basis of the control of the slaughter was revealed that the weight of the paired carcasses in calves from the experimental group was higher than that of peers, not consuming the Supplement, of 5.82-of 9.91%, and their output is up 0.09 to 0.86 percent. At the output of the pulp of the bulls of the experimental groups exceeded the control analogues by 0.72-1.05%. The meat index of their carcasses was, respectively, higher by 0.25-0.36. In average the sample of the flesh of the carcasses of young animals who consumed the study Supplement contained more protein compared with the control 0,28-0,57% fat, respectively 0,68-1,19%. The influence of feed additive and on the content of amino acids in meat was revealed. Thus, essential amino acid tryptophan in the longest muscle of the back of the bulls of the experimental groups was higher by 1.58 – 2.87% and protein quality index-higher by 0.37-0.63. The flesh of the carcasses of calves of the experimental groups had higher technological properties. The moisture-retaining ability of their longest back muscle was higher than that of analogues of the control, by 2,05-2,22%, the fading – lower by 2,04-2,41%. In the body of young cattle, consuming feed additive, protein was postponed more than in control, by 8,67-14,85% and fat – respectively by 11,96-21,44%. The conversion rate of protein they were higher by 0.78-0.86%, energy - respectively 0.67-1.06%. The level of profitability of beef production in the experimental groups was higher than in control at 4, 18-of 1.29%.

At the present stage of development of market economy, one of the most important tasks of the agricultural sector in Russia is to increase the production of agricultural products, which depends on the sustainable development of livestock industries and their intensification based on modern achievements. The agro-industrial complex and its basic type of economic activity - agriculture - are the leading system-forming spheres of the economy of the Chuvash Republic, which form the agri-food market, food and economic security, labor and settlement potential of rural territories. One of the tasks of the Chuvash Republic State program “Development of agriculture and regulation of the market of agricultural products, raw materials and food of the Chuvash Republic” for 2013-2020 is to stimulate the growth of production of main types of agricultural products and food products. A prerequisite for increasing agricultural production is increasing livestock productivity. The experience of using biological stimulants and feed additives under qualified use, with a predetermined task and in optimal quantities, indicates a rather high economic efficiency and safety for animals and humans.  Research has been conducted to study the effect of para-aminobenzoic acid on the quality of meat in young cattle. The experiments were carried out in the educational experimental farm of the Chuvash State Agricultural Academy. Three groups of young cattle were formed on the principle of 15 animals each. The control group received the main diet, to the first experimental group, para-aminobenzoic acid was added to the main diet at a dose of 0.5 mg per 1 kg of live weight, the second experimental group – 1 mg per 1 kg of live weight.  An organoleptic assessment of the quality of meat and meat broth indicates the biological usefulness of the meat of bull-calves treated with para-aminobenzoic acid. The chemical composition of the meat of bull-calves does not change significantly with the use of this vitamin.

Mineral Feed Additives

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.

Determining which forms of mineral feed additives can increase farm animal productivity is a key area of research. This study assessed the mineral composition of ruminal fluid and the effectiveness of calcium and phosphorus used by animals after the introduction of finely dispersed particles (FDP) of SiO2 (group I) and FeCo (group II) with a hydrodynamic radius of 109.6 ± 16.6 and 265 ± 25 nm, respectively. The deposition and use of calcium and phosphorus in the body of the experimental animals exceeded the control values. In group I, 30.8% more calcium was deposited (p ≥ 0.05), and in group II, the value was 30.3% (p ≥ 0.01). In the experimental groups, the calcium utilization rate was 27.3% higher in group I (p ≥ 0.05), and 28.2% higher in group II (p ≥ 0.01) compared to in the control. Phosphorus deposition was 34% higher (p ≤ 0.01) in experimental group I and 6% higher in experimental group II, compared with the control. Group I had a high utilization rate of phosphorus from the feed (with a 29% difference compared to the control). Comparison of the experimental groups revealed that the introduction of SiO2 FDP promoted an increase in the concentration of silicon, phosphorus, and calcium in the ruminal fluid. The introduction of FeCo FDP was accompanied by a decrease in the concentration of iron and cobalt in the ruminal fluid. Thus, the use of feed additive in finely dispersed form in the diet of animals was accompanied by an increase in the use of calcium and phosphorus by the animal’s body, which is advisable when intensifying milk and meat productivity. The obtained results require further research. Keywords: finely dispersed forms of microelements, ruminants, calcium and phosphorus exchange, feeding

The paper presents the study on an impact of feed additives Peak anti-stress and SPAO (SPAO-complex) with different lithium content on meat productivity and meat quality of broiler chickens. The feed additives exert a pronounced metabolic effect, have adaptogen properties and allow forming a mechanism that facilitates compensation of the expenditure of the body, which significantly increases upon stress development. It was established that the average daily gain of the broiler chickens increased by 1.8% and 4.3% on the background of using SPAO-complex and Peak anti-stress, respectively, compared to the broiler chickens that did not receive the feed additives in the daily diet. It was shown that addition of feed additives with lithium into a diet led to an improvement of the indices of broiler meat productivity and meat quality: a level of yield of the carcasses of the 1st category increased up to 56.2–79.1%, high organoleptic indices of meat were ensured, the protein content in white and red chicken meat increased and functional-technological properties of minced meat improved. The use of feed additives ensured profitability of industrial poultry production; the highest indices of profitability were established upon introduction of the feed additive Peak anti-stress into a diet — up to 8.67 rubles per each ruble of expenses. The obtained results of the study should be taken into consideration in the technological processes when raising broiler chickens.

Scientific publications describe the positive effect of feed additives and pharmacological complexes on metabolic processes in the body of broiler chickens, in particular, on the protein composition of the blood, meat productivity and protein accumulation in meat. The Peak-Antistress feed additive developed at the Department of Morphology, Physiology and Pharmacology of the South Ural State Agrarian University allows to reduce the technological load on the poultry body by stimulating the general metabolism and complex antioxidant action. Experiments on the use of the feed additive Peak-Antistress were carried out on broiler chickens of the final hybrid of the Arbor Acres cross in an industrial-type poultry farm with floor technology. The poultry was divided into three groups of 6,000 chickens each and kept in one workshop in separate sections. The control group received the main diet, the 1st experimental group received the main diet and feed additive at a dose of 1269 g / t of feed 5 days before slaughter, the 2nd experimental group received the main diet and feed additive at a dose of 1693 g / t of feed 5 days before slaughter. Slaughter of broiler chickens was carried out according to the technological instructions of the enterprise on the 38th day. Against the background of the use of the feed additive in the experimental groups of broiler chickens, stimulation of protein metabolism was observed, as evidenced by an increase in total protein in the blood by 7.9–20.1%, an increase in the level of protein in white meat by 0.1–0.3%, and a tendency to an increase in amino acids in white meat protein by 0.2–12.3%.

The article gives scientific substantiation of using silicon-containing new feed additive “Energosil” for replacement gilts. The studies were conducted in pig-breeding complex of the Center for Practical Training of Agricultural Specialists in Mordovia Republic. There were three experimental groups of replacement gilts (10 animals each). The effect of various dosages of Energosil (5.0, 7.5, and 10 mg per kg of body weight) on digestibility, nutrient utilization, and animal growth energy was studied. The most optimal dosage of a new feed additive in their rations was revealed, which constituted 5 mg / kg of the animal live weight. It was established that the animals from the first experimental group, who received silicon-containing feed additives of this amount digested the nutrients of the diet better than their counterparts from the other groups. Compared to the control group, the digestibility of dry matter increased by 3.62% (p<0.05), organic matter by 3.29% (p<0.01), crude protein by 4.09% (p<0.001), fat by 4.30% (p<0.01), cellulose by 3.79% (p<0.01) and nitrogen-free extractives by 2.03% (p>0.05).Replacement gilts of the first experimental group, who were given Energosil in the amount of 5 mg / kg body weight in addition to the basic ration, retained nitrogen in their bodies by 17.1%, calcium by 55.9% and phosphorus by 69.7% more than their counterparts from the control group. It contributed to an increase in body weight of gilts from the first group compared to control counterparts by 10.8%. Increased dosages of Energosil (7.5 and 10 mg / kg body weight) also had a better effect on the growth energy of gilts compared with the control group. The feed additive in the amount of 7.5 mg kg of animal  live weight contributed to an increase in animal weight compared with control counterparts by 6.21 kg or 4.8% (p<0.05), with a third experimental group by 4.4 kg or by 3.4% (p<0.05). When given Energosil in the dosage of 10 mg/kg, the body weight of gilts from the third experimental group was higher by 1.81 kg or 1.4% (p> 0.05) compared with the control counterparts.

The unresolved problem of quail is feed stress and high sensitivity of poultry of this species to feed quality. To eliminate such consequences it is possible with the use of various biologically active feed additives. However, their introduction into the diet automatically raises questions about the quality and safety of the products for the consumer. The purpose of the research is to conduct a veterinary and sanitary assessment of the quality of quail meat for feeding NDC. The purpose of the research is to conduct a veterinary and sanitary assessment of the quality of quail meat for feeding NDC. The object of study were the quails of the Pharaoh breed, at the age of 24 were divided into two groups: experimental and control 30 heads each. The birds were kept in cages with free access to food and water. Quails of the experimental group were added to drinking water feed additive "Nanocerium" at a dose of 8.6 mg per liter of drinking water. Nanocerium feed additive is an aqueous dispersion of NDC with average nanoparticle sizes of 2–7 nm. Antemortem examination of quails of both groups revealed a satisfactory clinical condition of birds. The average weight of the gut carcass of quails of the experimental group was higher by 8.3% compared to the control. Examination of 20 carcasses of quails showed that they can be classified as first class. According to organoleptic parameters, quail meat is of good quality in veterinary and sanitary terms. Microbiological studies of quail meat indicate no effect of NDC in the applied doses on its bacterial contamination. Chemical parameters of meat (pH, aminoammonia nitrogen, volatile fatty acids during storage in the refrigerator) (5 days, t = 4–5 ° C) tended to increase and were within the normal range for fresh product. Tissue in quails of both groups was not detected. The biological value of quail meat in both groups was identical and no toxicity. Tasting evaluation of the broth and meat showed that NDC did not affect the studied taste. The obtained results show that the quails that received the feed additive "Nanocerium" with water according to the indicators of veterinary and sanitary examination are of good quality, which allows to use it in human food without restrictions. Key words: poultry, nanocerium, organoleptic evaluation, microbial contamination, biological value, tasting evaluation.

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.
