One of the main branches of agriculture in the Republic of Sakha (Yakutia) is productive horse breeding. In this regard, we can use the valuable raw materials that the horse gives due to its high adaptability to local conditions. The development of productive horse breeding in particular dairy horse breeding under the conditions of the Republic of Sakha (Yakutia) would allow providing the population with natural, dietary food and more efficient use of land resources. The purpose of the work is to study the effect of zeolite and zeolite-sapropel feed additives in the ration of mares of Megezhek breed on the milk productivity and quality of kumiss under the conditions of Central Yakutia. Two scientific and economic experiments have been carried out where the influence of zeolite from the Suntar deposit (experiment 1) and zeolite-sapropel feed additives (experiment 2) on the milk productivity and physiological parameters of mares of Megezhek breed has been studied. The optimal doses of the effect of zeolite and zeolite-sapropel feed additives on the profi tability of kumiss production have been determined. It has been found in the first scientific and economic experiment that when adding 0,4 g of zeolite per 1 kg of live weight to the daily ration of lactating mares the level of profi tability of milk production increased to 20,4 %, and when adding 0,5 g per 1 kg of live weight the profi tability index increased to 21,5 %, compared to 13,7 % in the control group. In the second scientific and economic experiment the infl uence of the zeolite-sapropel feed additive on the intensity of digestion and assimilation of nutrients in the mares’ rations has been determined. The analysis of the experimental data indicates a high economic efficiency of using zeolite-sapropel feed additive in the 2nd and 3rd experimental groups of mares, where the level of profi tability of production was equal to 27,34 and 32,33 %, respectively, compared to 16,09 % in the control group.

Currently, the existing literature sources on the use of feed additives “Tetra+” and “Glimalask” do not fully reflect the data on the comparative study of their infl uence on the physiological state, meat productivity and pork quality of fattened young pigs. Under the conditions of the Lower Volga region comprehensive researches were carried out in a comparative aspect to improve meat productivity and pork quality through the use of feed additives “Tetra+” and “Glimalask” in the diets of young pigs on fattening. The purpose of the work was to increase the productive and pork quality of young pigs on fattening due to the use of feed additives “Tetra+” and “Glimalask” in their diets. The research was carried out in the period from 2012 to 2019. The experimental part of the work took place under the conditions of the stud farm named after Lenin in the Surovikinsky district in the Volgograd region. The object of research was young pigs of Large White breed. The positive influence of feed additives on the digestibility and use of nutrients in diets, meat productivity and pork quality, physiological indicators and economic effectiveness of pork production has been proven. It has been found that the level of profi tability of pork production was higher in the experimental groups in comparison with the control group by 5,03 and 4,48 %, respectively. At the same time the highest effectiveness has been obtained from the animals of the 1st experimental group, which received the feed additive “Tetra+” in the diet, which allowed to increase the live weight gain by 6,74 %, the level of profitability by 5,03 %. Thus, the feed additive “Tetra+” was the most effective.

Of the half-yearly animals, 40 males were selected and formed into group IV for the experiment. The differences were only in feeding. The young were fed the studied additive Vetosporin suspension. In this case, the supplement was an addi-tion to the basic diet of animals of the experimental II-IV groups. The volume of the additive added was 0.1; 1.0; and 2 ml per 10 kg of live weight, respectively. Control group I, consumed exclusively a diet that does not contain an additive. Based on the results of the experiment at the age of 18 months. The prevalence of bulls of the experimental live weight over peers was observed, which was 4.4-25.3 kg (0.78-4.67%). The study of the studied indicators after control slaughter in the context of groups showed the superiority of bulls of experimental groups in all the periods studied. It is established that at the age of 15 months. The size of the removable live weight of the youngest of the control group was less by 8.0-19.7 kg (1.75-4.29%) than in the animals of the test groups. In this case, the leading position was occupied by the youngest of group III, the prevalence of which was 0.7-11.7 (0.14 -2.51%). It should be noted that after 3 months a simi-lar picture of the distribution of the studied quantities was observed. As for the output of carcass, we can note the following. Outsider among the animals of the experimental groups was the control group. So the bulls of group I were inferior to those who received the additive by 0.7-1.3%. At 18 months, as well as at 15 months, the dominant position was occupied by gobies of experimental groups. It should be noted that among the animals of the experimental groups the leading place was occupied by the bulls receiving the feed additive in a dose of 1.0 ml per 10 kg of live weight, that is, the youngest of the III group.

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.

Poultry farming is one of the major branches of animal husbandry, which develops through concentration, specialization and intensification on the basis of poultry plants and poultry farms. The increase in production of eggs and poultry meat is based on a significant increase in the productivity of poultry with a simultaneous increase in its population with a high payment of feed by production and the increase in labour productivity. The purpose of the work was to study the influence of enzyme feed additives in the diets of laying hens on the quality of eggs. The researches have been carried out in PJSC “Poultry plant Chelyabinskaya”, which produces high-quality chicken eggs obtained from the poultry cross “Loman LSL-classic”. The object of study was enzyme drugs produced by Sunzyme – a multi-enzyme drug that includes xylanase, cellulase and mannase activities. The dosage of enzyme drugs in the feed mixture of laying hens was: Sunfyze 5000 – 80 g/t, Sunzyme – 100 g/t. The results of researches show that in the groups that received enzyme drugs in their diet, egg production was higher than in the control group. So, for the entire period of researches the hens of the experimental groups were significantly superior to the control group in terms of egg production per average laying hen. The largest difference was in hens of the 1st experimental group (enzyme drug Sunfyze) – 10,8 eggs; the smallest in hens of the 3rd group (enzyme drugs Sunfyze and Sunzyme) – 5,7 eggs. In hens of the 2nd experimental group compared with hens of the control group egg production was higher by 7,9 eggs. The best indicators of production efficiency have been obtained in the 1st experimental group of laying hens, which were fed with the enzyme feed additive Sunfyze to reduce the nutritional value of the diet according to the matrix.

It is the fact with the introduction of the detailed system of normalized feeding in the livestock industry, the productivity of farm animals has increased by 11,2 %. The obvious solution to the problem of feeding pigs with complete feed is seen in the use of feed and feed additives of local production, which will reduce the final prime cost of the product. The purpose of the work was to justify the use of feed additives Nabikat and Glauconite in feeding sows. During the experiment 3 groups of sows have been formed (a control group and two experimental ones). Sows of the control group have been received the main farm diet, sows of the 1st experimental group in addition to the main diet have been received the feed additive Nabikat (0,20 % of the dry matter of the diet), and the 2nd experimental group Glauconite (0,25 % of the dry matter of the diet). It has been found on the base of researches that the input of the feed additive Nabikat in the diet of pregnant sows has increased the prolificacy of sows by 16,3 %, the livability of piglets by 10,9 %, while the expenditures of feed has been reduced by 20,4 %. The lowest feed and digestible protein expenditures per live weight gain of a pregnant sow and a weaning piglet have been observed in the 1st experimental group when the feed additive Nabikat was included in the diet of sows. The highest feed payment for 1 weaned piglet has been observed when feeding the feed additive Nabikat to sows, which allows producing 24,3 heads of piglets in natural terms, in monetary terms of 1,92 heads. At the same time, it is possible to get an additional profit of 6,9 thousand rubles.

Promising in feed production is the preparation of haylage with subsequent storage of herbage together with preservatives. The modern market off ers various chemical preservatives in the form of organic acids: propionic, formic, benzoic and their salts. Some disadvantages of preservatives of this group (volatility, toxicity, venom, ability to cause respiratory burns, corrosion, etc.) require to organize a search for new ones based on bacteria and enzymes. The purpose of the work was to increase the level of milk productivity of cows and quality of milk by using the preservatives Biosib and Silostan in the preparation of haylage. Scientifi c and economic experiment has been carried out in LLC “Agrofi rma Bairamgul” in the Uchalinsky area in the Republic of Bashkortostan. For the research, 36 Holstein cows have been selected, from which 3 groups of animals have been formed based on the principle of analogues per 12 heads in each. The input in the ration of lactating cows of grain and legume haylage prepared using the technology with the use of preservatives Biosib and Silostan contributes to the increase in milk productivity. The best eff ect has been demonstrated when using the drug Silostan (the 2nd experimental group), which can be explained by the diverse biological composition of microbes, as well as amino acid complexes, enzymes, vitamins and trace elements. The increase in milk productivity of cows of the 1st and 2nd experimental groups allows to reduce the prime cost of production, respectively according to groups, by 38,7 rubles or 3,31 % and 51,1 rubles or 4,43 %; to increase revenue from the sale of milk by 3186,5 rubles or 4,32 % and 3664,0 rubles or 7,24 %; net profi t by 1791,9 rubles or 17,97 % and 2570,6 rubles or 25,78 % and the level of profi tability by 4,14 and 5,52 % compared to the control group.

Изучены особенности пищевого поведения коров-первотелок при скармливании ферментативно-пробиотических препаратов. Для изучения влияния пробиотиков на основе целюлозолитических бактерий рубца жвачных проводился опыт в условиях хозяйства Вологодской области. Были сформированы 3 группы первотелок черно-пестрой породы по 12 голов методом пар-аналогов с учетом кровности, удоя матерей за наивысшую лактацию, живой массы, количества дойных дней после отела и суточного удоя. Животные контрольной группы получали основной рацион,  коровам I опытной группы дополнительно скармливали по 50 г на 1 голову в сутки кормовую добавку на основе целюлозолитических бактерий рубца коров, а II опытной — такое же количество добавки на основе целюлозолитических бактерий рубца оленей. Продолжительность скармливания добавок составляла 90 дней. В результате исследований было установлено, что использование ферментативно-пробиотических препаратов положительно повлияло на пищевую активность и уровень молочной продуктивности первотелок. Коровы I и II опытных групп, получавшие дополнительно к основному рациону ферментативно-пробиотические препараты в сравнении с контрольной группой имели более высокие показатели по затратам времени на потребление корма — 8 и 25 мин., соответственно. Время, затраченное на жвачку, у первотелок II опытной группы было больше на 12 мин., чем у животных контрольной группы, в результате индекс пищевой активности у них был выше на 0,026 по сравнению с контролем. Использование добавок способствовало увеличению молочной продуктивности коров I и II опытных групп, по сравнению с контрольной, на 207 и 151 кг. Полученные результаты подтверждают положительное влияние ферментативно-пробиотических препаратов в кормлении коров, так как они способствуют повышению их пищевой активности и молочной продуктивности. The features of first-born cows’ nutritional behavior when feeding enzyme-probiotic preparations have been studied. To study the effect of probiotics based on the ruminants’ cellulolytic rumen bacteria, an experiment on a farm in the Vologda Oblast has been conducted. There were formed 3 groups of black-and-white first-born cows of 12 heads by the method of pairs-analogues, taking into account pedigree, mothers’ milk yield for the highest lactation, live weight, the number of milking days after calving and daily milk yield. The animals of the control group received the main diet, the cows of the I experimental group were additionally fed 50 g per 1 head per day of a feed additive based on cellulolytic bacteria of cow rumen, and the II experimental group were fed the same amount of an additive based on cellulolytic bacteria of deer rumen. The duration of feeding the additives was 90 days. The research found that the use of enzyme-probiotic preparations had a positive effect on the first-born cows’ nutritional activity and milk productivity level. The cows of the I and II experimental groups who received enzyme-probiotic preparations in addition to the main diet had higher indicators for the time spent on feed consumption in comparison with the control group — 8 and 25 minutes, respectively. The time spent on rumination was 12 minutes longer in the first group of experimental animals than in the control group; as a result, their food activity index was higher by 0.026 compared to the control group. The use of additives contributed to an increase in the milk productivity of cows of the I and II experimental groups, compared with the control group, by 207 and 151 kg. The obtained results confirm the positive effect of enzyme-probiotic preparations when feeding cows, as they help to increase their nutritional activity and milk productivity.
