There is an urgent need to develop new strategies to minimize the environmental impact of animal production and support sustainability of food production and consumption. Feed additives have been for a long time used in animal nutrition to improve animal growth and performance as well as animal health. Balsam poplar plants (Populus balsamifera) is well known as a rich source of bioactive compounds with positive health effects, and might be used in agriculture as a feed additive for ruminants. The aim of the present study was to evaluate the effect of balsam poplar-based additives on growth and performance of fattening young bulls of Simmental breed. In the present study, we used 4 combinations of extract from balsam poplar buds or its components as a feed additives. The animals were given the supplements at the age of 15 months, 3 months before slaughter. The growth and slaughter characteristics of young bulls were studied. After the first and second month of feeding with dietary supplements, animals from the groups fed 10% balsam poplar buds extract and dry shredded balsam poplar buds had significantly higher live weight compared to the control animals fed a diet without any supplements (P < 0.05). At slaughter, group fed 10% balsam poplar buds extract had significantly higher live weight compared to control. Average daily gain was also greatest in that group. Major sensory as well as physical and chemical parameters were not affected by balsam poplar-based supplements (p > 0.05 for all) and were in line with regulatory meat hygiene requirements.

To improve the adaptation of the pancreatic microflora to changes in the diets of calves and for the rational use of feed, in intensive cultivation, it is desirable to change the composition of feed probiotic supplements according to the age of the animals. Each age group of calves responds differently to live weight gain on probiotic feed additives. Feed supplement Immunobacterin-D containing Bacillus subtilis, Bacillus licheniformis has a positive effect on natural resistance, increases the average daily gain and has a preventive effect on diseases of the digestive tract of calves. But for 2 months of continuous feeding can cause suppression of natural resistance of some animals. When baker's yeast is added to the feed additive (B. subtilis, B. licheniformis 1 × 1010 CFU / g, Sascharomyces cerevisiae 1 × 109 CFU / g), the dry form of the product makes it possible to feed it with compound feed. The use of immunobacterin-D with yeast in 3-month-old calves in experimental animals in the clinical examination for fatness and coat condition looked better. Calves of the experimental group during this period added in increments of 276 g in the previous month, the arithmetic mean of the average daily gain of live weight was 820 ± 180 g, and in the current 1096 ± 90 g, which indicates a positive effect of yeast (especially live) on the productivity of calves at this age. For studies on heifers in a farm with lower average daily gains in live weight, we received a smaller percentage increase in gains with the use of feed probiotic supplement Immunobacterin-D with baker's yeast. When adding to the feed additives at a dose of 40 g and 20 g to heifers 350–400 kg live weight of the animal had an average daily gain of live weight in the first group of 500 ± 17 g, in the second 440 ± 30 g, and in the control 414 ± 12 g, which is 20.8 and 6.3 % more than in the control group. The use of yeast in feed additives confirms the pattern of increasing the percentage of additional average daily gain. That is, with higher average daily gains, we get a higher percentage of additional growth from feeding a probiotic feed additive containing baker's yeast.

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

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.

Experimental studies have shown an increase in productivity, metabolic processes, the effectiveness of the use of nutrients and biologically active substances and the metabolic energy of diets, the health of heifers aged 1–6 months under the conditions of industrial technology of their rearing. Increasing the productivity of heifers is closely related to improving the nutrition system during all periods of rearing with the use of the vitamin complex Vitaminol in diets depending on their age and body weight. The highest effectiveness of rearing young animals has been established when using Vitaminol in doses: 1,3 g/head./day – up to 1 month, 2,4 g/head./day – 2 months, 3,3 g/head./day – 3 months, 4,3 g/head./day – 4 months, 4,8 g/head./day – 5 months and 5,3 g/head./day – at the age of 6 months. Differentiated feeding of optimal doses of feed additives to calves increases the digestibility of dry matter by 1,41–10,8 %, organic matter by 1,6–10,0 %, raw protein by 1,6–6,8 %, raw fat by 1,4–8,7 %, raw fiber by 1,5–3,0 % and nitrogen-free extractive substances by 1,6–6,0 % depending on age and body weight (from 1 to 6 months inclusive). It has a positive effect on the absorption of nitrogen and the use of calcium and phosphorus in the body. The use of Vitaminol in diets of calves contributes to an increase in live weight and average daily gain compared to the control group. In calves up to one month of age (at the dose of 1,3 g/head/day) live weight increased by 6,5 %, the average daily gain by 11,4 %, in 2 months (at the dose of 2,4 g/head/day) these indicators were 2,9 and 2,6 %, respectively, at 3 months (at the dose of 3,3 g/head/day) – 3,4 and 8,2 %, in 4 months (at the dose of 4,3 g/head/day) – 6,7 and 12,8 %, in 5 months (at the dose of 4,8 g/head/day) – 4,4 and 3,6 % and at 6 months (at the dose of 5,3 g/head/day) – 4,3 and 2,7 %, respectively. In order to improve the quality of feeding when rearing calves, more fully realize their genetic potential, increase productivity and use of nutrients in diets and normalize metabolic processes in the body we recommend the optimal doses of the feed additive Vitaminol depending on age (g/head/day): 1,3 – in 1 month, 2,4 – in 2 months, 3,3 – in 3 months, 4,3 – in 4 months, 4,8 – in 5 months, 5,3 – in 6 months. Feed additive Vitaminol enter into the composition of complete feed, wet feed mixtures and feed to calves 1 time per day.

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 effectiveness of forest resources depends on the comprehensiveness and rationality of their consumption and processing into finished products. This article discusses the problem of using solid fir wood greenery residues generated during the industrial production of essential oils. Bioconversion is considered to be the most promising use. The objective of this research was to study the chemical composition of bioconversion products of fir wood greenery-based substrates. The РР-3.2 strain of Pleurotus pulmonarius (Fr.) Quél was used as a biodestructor. In the process of bioconversion, the contents of polysaccharides and lignin substances is reduced to 38% and 28%, respectively. Up to 20% of protein accumulates in bioconversion products of fir wood greenery. The amount of nucleic acids is not more than 1.5 g per kg; the contents of heavy metals, such as mercury, cadmium, arsenic, and lead, do not exceed the maximum permissible concentration standards. The substrate weight loss reaches 15%. When fallen leaves and post-extraction poplar bud residues are added to the substrate, the substrate-destroying activity of fungi increases, and the protein content increases by 3%. The digestibility of products as a result of bioconversion increases 1.6–2.8 times depending on the substrate composition. The obtained data support the recommendation of post-fermented substrates based on fir wood greenery and balsam poplar biomass for use as a protein feed additive.
