The article covers addition of chlorella suspension, its effect on nitrogen balance, digestibility of nutrients and amino acids, pig productivity. Various feed additives, micro-element mixtures, and vitamins are used in animal nutrition to deal with the deficiency ofcertain vitamins and mineral elements in the rations. The peculiarity of chlorella suspension as a feed additive is in the ability to cultivate it throughout the whole year and in the availability of optimized technologies for its cultivation and use. Chlorella suspension is rich in proteins, minerals, vitamins, fatty acids and fiber. Introduction of chlorella suspension into pigs’ diets has helped to increase the digestibility coefficients of both inessential (by 7.5 %) and essential (by 2 %) amino acids. Feeding the animals with chlorella suspension has also resulted in the release of nitrogen retained in animals’ bodies by 13 % compared to the control group. The additional use of chlorella suspension in the diet of fattening pigs (large white) was found to increase the average daily gain by 21.9% compared to the control group which did not receive chlorella suspension. The conversion of animal feed to obtain 1 kg of live weight gain in the control group was 5.1 kg, in the experimental group - 4.2 kg, and the conversion rate of feed in the experimental group was higher by 21.4 %.Feeding young pigs with chlorella suspension increases the digestibility of protein by 4.5 %, fiber by 2.0 %, fat - 0.7 %, essential amino acids - 81.6 %. The introduction of chlorella suspension to pig rations leads to an increase in the level of nitrogen in their body by 54.7 %of that taken with feed and 69.15 % of that digested in the body. Pork production profitably using chlorella suspension stood at 12.3 % , which is more by 87,8 % compared to the control group.

Mycotoxins have been formed in feed are secondary metabolites of fungi and are quite stable substances that have teratogenic, mutagenic and carcinogenic effects. An effective way to combat mycotoxins in feed is the use of feed additives that adsorb toxins, prevent their absorption in the gastrointestinal tract of the animal and are excreted from the body. The infl uence of coconut enterosorbent Shelltic Es on fattening and meat qualities of young pigs has been studied. It has been found in the process of fattening that the highest feed digestibility was in pigs of the experimental group, in the diet of which enterosorbent has been added. The results of studies of the chemical composition and technological properties of pork have been provided. The positive eff ect of enterosorbent on precocity, absolute average daily gain of live weight and reduction of feed expenditures per 1 kg of gain has been revealed. In pigs from the experimental group the average thickness of the fat was higher and the area of the “muscle eye” was lower compared with animals of the control group, which indicates that higher rates of carcass yield have been obtained due to faster accumulation of fat tissue. The weight of internal organs of pigs indicates the intensity of metabolic processes in the body. In experimental animals the weight of the lungs was 0,1 kg lower, and the liver and heart were higher by 0,13 and 0,01 kg, respectively. Enterosorbent had no effect on the content of vitamins in the liver of pigs of the compared groups. The content of impurities of organochlorine toxicants and toxic elements in the meat and liver of animals of the experimental group was lower than that of control analogues. Therefore, the use of enterosorbent Shelltic Es promotes more active excretion of them from the body.

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.

A study of the effectiveness of the use of feed additive Liaform in relation to its effect on the growth and development of broiler chickens. For research, 2 groups of broiler chickens of 55 heads (control and experimental) from 8 days of age were formed on the principle of analogues. Feeding of the control group was carried out with standard complete feed. Feeding of the experimental group was carried out with standard complete feed, in which the feed additive Liaform was added at the rate of 2 g / kg. During the experiment, the general condition of the bird, the safety of the bird, zootechnical and hematological parameters were monitored. It is established that the studied feed additive has a positive effect on the productivity of broiler chickens, improves feed absorption. As a result of the use of feed additive Liaform live weight of broiler chickens in the experimental group was 4.3 % higher compared to the control. The average daily gain of chickens in the experimental group exceeded this figure of chickens in the control group by 4,1 %. The use of feed additives helped to increase feed conversion. The use of Liaform feed increased the protein level in poultry meat

Aim. The effectiveness of the use of the mineral feed additive bischofit in the diets of young sheep in the South of Russia at various doses and its impact on the productive qualities of young sheep. Materials and Methods. The material for conducting the experiment in this household was the livestock of sheep of the Grozny breed on fattening. The sheep of the control group received a basic household diet, the I experimental group received 5 ml of bischofite per head per day in addition to the main diet, the II experimental group received 8 ml of feed additive. Classical zootechnical methods were used in the process of work, including wool yield and physical and technological properties were studied individually in 3 experimental animals from each group according to the VNIIOK method. The research materials were processed by the methods of variation statistics using the Microsoft Office software package. Results. Young sheep from the I experimental group, who received bischofite at 5 ml / head per day, were 9.4% more in live weight than in the control group. Young sheep that received 5 ml of feed additive had the best meat index, and exceeded the control group in terms of pulp yield by 12.5%. The maximum deviation from the average value of the cut of pure wool in the upward direction (110.6%) was observed in I experimental group. The most durable wool of 7.24 sN / tex is found in the group that received the bischofit feed additive as part of the main diet. Conclusion. To compensate for the lack of mineral substances of the natural and environmentally safe feed additive bischofit at a dose of 5 ml / head per day, it changes the metabolic reactions in the body in a positive way, which is confirmed by an increase in the growth of live weight and wool productivity.

In providing the population with high-quality and cheap beef a signifi cant role is assigned, and in the future will be assigned to beef cattle breeding. The development of this industry and its eff ectiveness depends on the correct use of available feed resources. With the development of the feed industry the main task of which is mainly to ensure that in a small volume, as much as possible, as many sources of nutrients in a highly digestible form, the use of feed additives becomes important. Feed additives as a rule should compensate for the missing elements in the ration. The level and ratio of nutrients in them have a stimulating eff ect on the growth of muscle tissue and the formation of a strong backbone. The purpose of the work was to study the eff ect of the feed additive Vermiculite on the live weight of Kazakh White-headed steers. In order to study the feed additive Vermiculite in the rations of steers a scientifi c and economic experiment has been carried out on the basis of LLP “Terra” in the Kostanay region in the Republic of Kazakhstan. Two groups of steers have been formed for this purpose with 10 heads in each. The control group has received a basic feeding ration consisting of corn silage, haylage, wheat straw, complete feed (wheat, barley). The experimental group has received 200 g of Vermiculite per 1 head/day in addition to the main ration. During the entire period of the experiment the steers of the experimental group had the highest indicators of average daily growth compared to their herdmates in the control group. The highest value of the average daily gain in both groups has been observed in the period of 8–12 months, amounting to 1123,3 g in the control group, and 1159,2 g in the experimental group. The diff erence in favor of the steers of the experimental group was 35,9 g or 3,2 % (P < 0,01). In general during the experiment the diff erence in the average daily gain in live weight between the groups was 31,1 g or 3,5 % in favor of the animals of the experimental group.

Currently it has become popular to use different feed additives that allow us to increase the indicators of live weight gain by accelerating the metabolic processes in the body of animals, which allows us to take everything from the feed and to the maximum. With the advent of this trend in the market the range of feed additives in different directions has increased. For the research we have selected Vermiculite Expanded as a feed additive. The purpose of the research was to search the dynamics of changes in blood parameters in experimental steers in comparison with the control group against the background of the use of the feed additive Vermiculite Expanded. An assessment of blood parameters of Kazakh White-headed steers against the background of the use of mineral feed additive has been presented in the article. Three groups of steers have been formed for the research: the 1st group has been as a control and received the main economic ration; the 2nd and 3rd experimental groups received the feed additive to the main feeding ration in doses of 10 and 15 g/head for the groups, respectively. On the laboratory base blood tests we were able to search the correlation between morphological and biochemical parameters of blood and the growth rate of experimental steers. The steers of the 2nd and 3rd groups during the experiment had an advantage in blood serum indicators in terms of both total lipids and glucose, in the end, the difference in percentage ratio with the control group was 14,08 % in the 2nd group and 12,60 % in the 3rd experimental group. It is worth noting that the concentration of phosphorus and calcium in the blood was at the high level, which in our opinion reflects the influence of the feed additive Vermiculite Expanded.

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.

Increasing the production of pork meat requires careful work not only in terms of breeding, but also in the organization of complete feeding of animals, the correct selection of feed and feed additives containing the necessary nutrients. The purpose of the work was to analyze the use of premix in feeding young pigs on fattening. Two groups of fattening young pigs (Large White×Landrace) have been selected for the researches using the method of analogous groups, taking into account the breed, age, and live weight per 20 heads in each group with a live weight of 35 kg. Pigs of the control group have received the main economic diet, and animals of the experimental group have received an additional premix Khutorok at the rate of 10 g of premix per 1 kg of feed. The results have shown that the best age to reach 100 kg was in the experimental group of pigs – 215,8 days, which received premix with feed that characterizes their higher precocity by 36,3 days (P < 0,001) than in the control group of animals. The use of this premix had a positive impact on the livability of young animals, in the experimental group it was by 9,3 abs.% more than in the control group of animals. Thus, the best fattening traits have been possessed by young pigl of the experimental group have been received the premix Khutorok in their diet at the rate of 10 g of premix per 1 kg of feed. The obtained data indicate the feasibility of using the premix Khutorok in the feeding pigs for fattening.
