The article presents the results of studies on the effect of increased fiber levels in combination with the probiotic Profort in SK-1 mixed feed on the formation of metabolism in the body of pregnant sows, in SK-2 mixed feed on the formation of microbiocenosis and nonspecific immunity in lactating sows in the conditions of the pig complex LLC "Agronika" of the Kursk region. The tested mixed feed SK-1 has an optimal structure of feed ingredients, which corresponds to the physiological state of deepfat sows. At the same time, the fiber content increases to 8.0%, the crude protein content is 176.3 g / kg at the exchange energy level of 10 MJ/kg. The SK-2 compound feed for lactating sows contains 12.87 MJ / kg, crude protein-18.3%, crude fat-4.86%, crude fiber-4.93%. The studies found that the blood serum of the experimental group of pregnant sows significantly (P < 0.05) higher glucose and total protein, the tendency of growth of gamma-globulins indicates an increase in the immunological reactivity of the sow body. There is a tendency to increase a-globulins and b-globulins. Indicators of enzyme activity in-dicate the intensity of metabolic processes in the body of deep-fat sows. The indi-cator of alkaline phosphatase, in the experimental group, tends to increase by 2.8 times, the decrease in the indicator of the amylase enzyme in the experimental group by 1.2 times. Increased lipase activity in the experimental group by 2.2 times. In studies of the facies environment of lactating sows, a positive trend of re-ducing the conditionally pathogenic microflora was established, while an increase in Bifidobacterium to 107 CFU/g was found, with a decrease in E. from 60 to 105 CFU / g, which indicates a positive dynamics of microbiocenosis due to an increase in normal microflora. Th ratio/Ts in the blood of sows of the experimental group increased due to an increase in the number of T-helpers by 73.8% , while reducing T-suppressors by 85.9 %. An increase in the blood content of animals of the second group of G-class immunoglobulins indicates a decrease in the antigenic load on the body.

The physiological state of animals is to a certain extent characterized by hematological indicators, since blood occupies a special place in the body. By transferring nutrients and biologically active substances, the blood performs the general regulation of vital functions of the body. The use of Vitartil as a feed additive in the diets of animals leads to an increase in glycolytic processes and a decrease in the body’s need for oxygen delivery, which contributes to the growth of the animal body. The purpose of the research was to study the changes in blood parameters taking into account the age of Hereford steers against the background of the use of Vitartil feed additive to the main diet and its effect on the productive traits of animals. In order to carry out the experiment two groups of steers-analogs of Hereford breed have been formed at the age of 6 months per 10 heads in each. The difference between the groups was that the steers of the experimental group have been received the feed additive Vitartil in addition to the main diet. The greater yield of the meat part was in the steers of the experimental group in comparison with the herdmates of the control group. This indicator in the experimental group was 78,9 %, while in the control group it was lower by 1,6 %. The animals of the experimental group were superior to their herdmates in terms of meat weight by 1,4 kg or by 8,8 %. The relative number of bones was lower in the experimental group and amounted to 18,4 %, and in the control group 19,2 %. The meat content index was high in the steer have been received the biologically active additive Vitartil and was 4,3, and in the control group 4,0. It has been found that the use of Vitartil feed additive to the main diet of Hereford steers increases the blood content of hemoglobin and glucose, which has a certain effect on the morphological and chemical composition of meat, as well as increases its energy value.

Due to the impact of adverse environmental factors, unsatisfactory conditions of pig population, deterioration of food supply, abuse of antibiotics, lack of preventive measures, leads to the development of diseases among pigs, especially young, which leads to a decrease in resistance, body performance, reproduction and reduction of livestock, as well as large economic losses. The use of bacterial preparations from living microorganisms can significantly reduce or even eliminate the use of antibiotics and hormones in the cultivation of healthy animals, to obtain high-quality and safe high-grade products. The aim of the work is to study the effect of probiotic EM – 1 on the physiological state and productivity of young pigs of large white breed. The experiment was conducted on two groups (6 heads each) of animals-analogues, starting from 60 days of age, for 2 months. Animals of the control group received feed produced in the farm. Piglets of the experimental group in addition to the main diet received 5% of feed fermented with em-1. Evaluation of the physiological state and productivity of young pigs was carried out on 60, 90 and 120 days of experience according to the methods adopted in clinical practice. Hygienic, hematological, biochemical, zootechnical and statistical methods of research were used in the performance of the work. The use of probiotic EM-1 in animals of the experimental group led to an increase in hemoglobine concentration by 7.7%, an increase in the number of red blood cells by 13.7%, the total number of leukocytes by 9.52%, and glucose concentration by 11.4%. The advantage of the viability of these pigs for the content of total protein (P < 0.05), γ–globulins by 18.6%, the activity of aminotransferases (AlАT, AsAT; P < 0.05), the average daily gain increased by 12.3% at the end of the experiment. For feeding piglets feed with probiotic EM-1 increased metabolic processes, resistance and productivity of the body, which indicates a higher level of redox reactions in their body.

Today feeding disorders (deficiency of crude protein and limiting amino acids), the use of feed contaminated with microscopic fungi can lead to immune depression. When feeding dysfunctional feed, the live weight gain of young animals and fattening pigs is reduced by 10-90%, depending on the balance and completeness of the rations in terms of nutrients. The article assesses the degree of contamination of feed with microscopic fungi and studies the effect of eliminating the deficiency of crude protein, lysine and methionine on the health status and weight gain of laboratory rats when feeding moldy wheat grain. A balanced for essential amino acids feed allows reducing the stress of the body's defense system from the negative effects of saprophytes. An experiment was carried out on 200 (10 groups, n = 20) weaned rats of the Wistar line in order to comparatively study the consequences of feeding the diets containing wheat grain contaminated with fungi of the genera Aspergillus and Penicillium, deficient and balanced to the norms of the requirement for crude protein and two essential amino acids - lysine and methionine. The number of micromycete reaches 109 CFU (spores) in 1 gram of feed. These molds are dangerous because of the possibility of their spores entering the body of animals and germinating in the lungs, liver, kidneys, heart, intestines, reproductive organs, and muscle tissue. Once in the blood, mold spores spread throughout the body. A complete zootechnical analysis of grain was carried out in the toxicology laboratory using the methods of zootechnical and biochemical analyzes of feed, livestock products and metabolic products. The negative effect of microscopic fungi on the health indicators of white rats is less pronounced with a balanced diet for essential amino acids. A decrease in the tension of immunity, expressed in a decrease in T-cell deficiency and activation of phagocytosis, was determined. The average daily gain on the contaminated feed decreased by no more than 20%, while the gain on the contaminated diet was 50-60% lower.

Among the environmental factors, feeding is the most important in the formation of new traits and properties. The level of feeding influences first of all on the digestive system. Then the nature of feeding affects the organs associated with the utilization of nutrients, and ultimately the body as a whole. The purpose of the researches was to study the correlation between productive and hematological parameters in steers against the background of the use of the feed additive Biovitel. The research has been carried out under the environments of JSC “SHF Dubrovsky” in the Chelyabinsk region on steers of Hereford breed. In order to carry out experiments 2 groups of steers (control and experimental) have been formed with 10 heads in each. The method of pair-analogues has been used taking into account the genotype, age, birth weight and physiological state of animals. The experiment has been conducted from 6- to 15-month-old steers. The control group has been received the main farm ration. The experimental group has been received the basic ration and additional feed additive Biovitel at the rate of 100 g/head/ day for 15 days. The correlation between hematological parameters and productivity of steers against the background of the use of the feed additive Biovitel has been determined. During the study a positive correlation between the total protein and protein fractions with the live weight of steers has been observed. High correlation coefficients have been obtained in steers of both groups at the age of 9 months. The amount of total lipids in all age periods in both groups changed relatively little, but the trend of their increase in steers of the experimental group remained. The concentration of phospholipids in the control group was almost at the same level, and in the experimental group there was an excess of control values by 5,52 %. Activation of redox processes in the animal body has been observed under the action of the feed protein additive Biovitel.

One of the approaches to the creation of biologically active additives in pig nutrition can be the use of phytopreparations, in par-ticular, 20-hydroxyecdysone (20-GE), which regulates protein metabolism in piglets. The aim of this work is to assess the effect of 20-GE on the metabolism of proteins in the body and to measure their turnover in grow-ing boars. The experiment was carried out on boars (♂ Danish Yorkshire × ♀ Danish Landrace) from 60 to 120 days of age. At the age of 60 days, boars were divided into 2 groups: control and experimental, fed with feed with a content (g / kg) of crude protein 158.7, lysine 7.7, threonine 4.8, methionine 4.6, exchange energy (EE) 12.7 MJ / kg. The ratio of the first limiting amino acid lysine to EE was 61%. The boars of the experimental group were injected with 20-GE at a dose of 1.6 mg / kg of body weight. In boars of the experimental group, compared with the con-trol, there was a decrease in urinary nitrogen excretion (by 26.8%, P≤0.05). Nitrogen re-tention was higher in boars of the experi-mental group by 19.0% (P≤0.001) compared to the control. The results of studies on pro-tein turnover obtained using a stable isotope indicate that the anabolic effect of 20-GE isdetermined by an increase in the rate of pro-tein synthesis at the same rates of their deg-radation, nitrogen flow against the back-ground of a decrease in its endogenous loss-es. 20-GE by activating a signal through protein kinase B provides an increase in bio-synthetic processes at the stage of transla-tion. It was concluded that the use of 20-GE in boars cultivation increases the efficiency of using amino acids for the synthesis and deposition of proteins in the body.

To study the effect of different doses of feed additive TC VMP in the composition of complete feed granular feed on the digestibility of nutrients and retention of Nitrogen in young rabbits with intensive cultivation technology, a scientific and economic experiment was conducted. To carry out a balance experiment, four rabbits were selected from each group of test animals, which were placed individually in specially equipped cages. The experiment was performed by the method of groups in three periods: preparatory – 7 days, preliminary – 5 days, accounting – 6 days. Analysis of feed, feces, urine was performed according to generally accepted methods of zoochemical analysis. For feeding young animals of experimental groups of rabbits used complete ration granular feed, in the structure of which there was a different content of feed additives. Rabbits were fed complete feed granular feed where the content of wheat bran was – 25.7%, barley grain – 13.0%, corn grain – 5.0%, soybean meal – 2.5%, sunflower meal – 15.0%, hay flour alfalfa – 25.0%, oats – 10.0%, table salt – 0.35%. The nutritional value of granular complete feed for all experimental groups of rabbits was the same. According to the balance experiment, the best indicators of nutrient digestibility were found in young rabbits of New Zealand breed, with a feeding dose of feed additive TC VMP in the composition of granular feed – 3.5%. At this dose, the coefficient of digestibility of organic matter was 63.3%, crude protein – 67.9, crude fat – 74.1, crude fiber – 24.8 and nitrogen-free extractives – 72.3%, which increased the digestibility of organic matter by 2.5%, crude protein by 3.9% (p≤0.05), crude fat by 2.9%, crude fiber and BER by 1.9 and 2.6%, respectively, in young rabbits, with intensive rearing on meat. It was found that in the body of animals of the experimental group, which were fed as part of the feed additive of TC VMP in the amount of 3.5%, the ratio between the amount of nitrogen absorbed from the consumed rabbits of this experimental group was dominated by animals from the control group by 2.92% 0.05). Thus, research data indicate a positive effect of feed additive TC VMP on the growth and development of young rabbits of New Zealand breed.

Mycotoxins cause severe diseases in organisms of human and animals. They are difficult to diagnose, cause great economic damage. Sorbents are able to effectively bind and remove from the body through the digestive tract with a therapeutic or prophylactic purpose various endogenous and ekzogenous substances, microorganisms and they toxins, supermolecular structures and cells. The aim of the work is to study the effectiveness of use of Alfasorb for the neutralization of mixed fodders affected by mycotoxins and they impact on blood’s indexes and productive qualities of piglets of Large White Breed. Experience was conducted on 30 ty piglets. Animals of the control group received mixed feed that was produced in the conditions of the farm. The pigs of experimental group in addition to the basic diet received Alfasorb. We determined blood’s indexes for study the effect of feed additive Alfasorb on the physiological state of animals at 4 months of age. A morphological and histological study of liver was carried out. The analysis of the average daily weight gain of piglets showed that it was higher in period of growth in the animals of experimental group. In the animals of the experimental groups there was an increase in the number of red blood cells in comparison with the control. An unreliable decrease in blood serum levels which characterize the level of intermediate metabolism of proteins in the body (content of urea, creatinine and common bilirubin) was established in the animals of the experimental group as compared to the control group respectively by 22.83% ( td = 0.98, P ≤ 0.05), 7.12% (td = 1.92, P ≤ 0.05) and by 20.54% (td = 0.86, P ≤ 0.05). Most hepatocytes had large nucleus and intense color of the cytoplasm. This indicates the absence of alterative processes in the body. The results of the studies make it possible to assert that the inclusion the 0.2% Alfasorb to the compound of feed which contaminated with mycotoxins significantly reduces their negative effect on the piglets organism, has a positive effect on the growth rate, on the course of metabolic processes, also it promotes an increase in the liver of medium-sized hepatocyte nuclei, stimulates biosynthetic processes in that cells and ensures the formation of a full structure of histohematological barriers in the organism.

Digestibility of the feed nutrients and the chemical elements balance in broiler chickens were studied under use of mixed feed with sulfate and Zink-mixed ligand complex in the physiological experiment that was conducted in the vivarium of the Bila Tserkva National Agrarian University. A tendency to increase the level of feed nutrients digestibility in the experimental groups of broiler chickens consuming mixed fodders with Zinc-mixed ligand complex was revealed in the conducted experiment. The nutrients digestibility indices were the highest in the chickens of the experimental group 3 where Zink-mixed ligand complex was added to the mixed feed. 45, 37.5 and 30 g of the element was added per 1 ton of mixed feed, respectively, for the growing period of 5-21, 22-35 and 36-42 days. The protein digestibility in this group was 89.2, fat - 82.5, fiber - 12.9 and Nitrogen free extractive substances (NFES) - 83.8%. The lowest digestibility indices of the nutrients were in the control group chickens, which, depending on the age, consumed feeds added with Zinc sulfate at doses corresponding to the introduction of 60, 50, and 40 g of the element per 1 ton of feed - 60.8, 80.2, 11.27, and 82.2%, respectively. Indicators of Nitrogen, Calcium, Phosphorus, and Zinc deposits in the body were also higher in the chicks of the experimental group 3 consuming the feed with Zink-mixed ligand complex. Feeding the birds with Zinc-mixed ligand complex as a component of mixed feed, in comparison with sulfate, improves the nutrients digestibility and increases the amount of chemical elements deposited in the body, which makes it possible to reduce the dose of the additive.

The research objective is to establish Hyplus meat breed of young rabbits and to determine growth and development characteristics during the period from weaning to slaughter age under conditions of the biologically active feed additive of humic nature «Humilid» introducted into their general diet. The control and experimental groups of animals were formed according to the principle of similar groups. Experiment study lasted for 35 days, including 7 days preparatory period, 21 days research period and 7 days aftereffect period. The young rabbits of the control and experimental groups were fed with the main diet, which included compound feed with an individual calculation of nutrients per animal. The young rabbits of the experimental group were additionally injected with a biologically active feed additive «Humilid» in the form of an aqueous solution in an amount of 5 mg/kg of body weight according to the active substance to the main diet for 21 days. During the experiment, the effect of «Humilid» on the growth and development of young rabbits and their physiological state was studied. The weighing of young rabbits in the experimental groups was carried out once a week. At the same time, their body weight was determined on average and average daily growth, the safety of the livestock, in addition, the weight and mass index of the liver, heart and kidneys after slaughter by the calculation method. With the introduction of the feed additive «Humilid» to young rabbits, an increase in the body weight of the animals is observed throughout the experiment. The body weight on average of young animals of the experimental group exceeded this indicator in comparison with animals in the control group by 17.2 % (p˂0.001). Under the conditions of the introduction of the biologically active feed additive «Humilid» over the period of the experiment, the average daily weight gain of young rabbits in the experimental group was higher by 20.7 % (p˂0.01) compared to this indicator in the animals of the control group, respectively. The safety of the livestock was 100% in both groups. However, it should be noted that young rabbits of the control group had more pronounced motor activity and signs of anxiety than the animals of the experimental group, which obtained the feed additive of humic nature «Humilid». When «Humilid» was used in the diet, the mass of organs and the index of their development in young rabbits in the experimental and control groups of animals were within the range of age-related changes, which indicates the non-toxic effect of this additive.
