One of the main promising areas in the technology of pigs feeding and the development of the industry is the use of enzyme preparations. Enzymes are specific proteins, that fulfill the role of biological catalysts in a living organism. Enzymes, unlike hormones and biostimulants, do not act on the animal organism, but on the components of the feed in the gastrointestinal tract, they do not accumulate in the body and products of animal husbandry. The scientific and economic experience was carried out on the basis of the CJSC “Progress” enterprise of the Yalchik district of the Chuvash Republic from May to October 2015. Studies were carried out on young pigs of large white breed at the age of 2 to 7 months. Three groups of clinically healthy gilts were formed according to the principle of analog groups of 12 heads in each one. The duration of scientific and economic experience was 150 days. The pigs of all groups were in the same conditions of feeding and maintenance, and they were fed mixed fodders in accordance with detailed feeding standards. Control samples are animals that received mixed feed, used in the farm when feeding young pigs. The feedstuff of the first experimental group was enriched additionally with a mixture of enzyme preparations №1 and №2, the second test group with mixture №1 and №3. At the beginning of the experiment in all groups, the average live weight of pigs was almost the same and amounted to 17.8 to 18.1 kg. At the end of the experiment, this parameter in the control group was 112.0 kg, in the first test group - 125.1 kg, in the second test group - 120.3 kg. Feed costs per 1 kg of gain were 4.82 energy feed unit in the control group, 4.25 energy feed unit in the first group and 4.44 energy feed unit in the second test group. The production was received for 1 ruble of additional costs in the first experimental group to 8.29 rubles and to 6.06 rubles in the second experimental 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.

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.

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.

The article presents an analysis of the use of antibiotic therapy in pig breeding and offered an alternative to them in the form of prebiotic supplements. Studies were conducted on the effect of probiotic drugs on the body of large white pigs in the farm-breeding plant Named after Lenin of Surovikinsky District of Volgograd Region and lasted until 180 days of age. For the experiment, 2 groups of Large White piglets of 2 months of age were formed. Each experimental group consisted of 15 pigs. Animals of the control group received standart farm animal diet (SD), analogs of the first experimental group SD + mixture of dietary supplements “LactuVet-1” and “Chlorelact” at a dosage of 0.2 mg / kg of live weight each. Deep studies were conducted on the effect of probiotic supplements to live weight gain, natural resistance, immunoglobulin reactivity, and slaughter indicators of piglets. Superiority of pigs from the experimental group in almost all the studied indicators over the peers of the control group was established.

The research was conducted on two groups–analogues of young pigs of large white breed with 10 pigs each. Weaned piglets at the age of 28 days were fed with the protein–vitamin mineral supplement «Minaktyvit» – starter in the amount of 25% of grain feed (33 days), while young pigs in growing were given the protein–vitamin mineral supplement «Minaktyvit» – grower in the amount of 15% (50 days) and those in fattening the protein–vitamin mineral supplement «Minaktyvit» – finisher in the amount of 10% (62 days). The control group received protein–vitamin mineral supplement. At the end of growing with the live weight of 100 – 110 kg a control slaughter was carried out and samples of stomach, small and large intestines for laboratory tests were picked out. Studies have shown that feeding of young pigs with the protein–vitamin mineral supplement «Minaktyvit» increases the average daily gains by 95 g or 15.68%, while their level is 701 g in the experimental group of animals and 606 g in the control one. The protein–vitamin mineral supplement «Minaktyvit» incredibly affected the morphological parameters of the stomach in the experimental group of pigs. However, the thickening of the walls by 4.3%, 5% and 10.9% respectively is observed in cardiac, fundic and pyloric areas of the experimental group, compared to the control one. The thickening of the walls in stomach areas under the influence of feed factor is associated with increasing of the mucosa thickness. Mucosa increased by 0.1 mm in the cardiac area, 0.36 mm in fundic and 0.53 mm in the pyloric one. The change in the structure of the investigated jejunum is observed while consuming the protein–vitamin mineral supplement «Minaktyvit» in the diet. The wall thickness increased by 17.57% (P < 0.05), including the thickening of mucosa by 16.7% and that of serous–muscular shell by 18.8%. No significant difference in the structure of the colon in the experimental group of animals was determined.

The aim of the work was to study the influence of stimulant drugs – the regenerating biological stimulant (RBS) and Imunolac on the immunological state and productive qualities of piglets. RBS is a complex of organic compounds of animal tissue that stimulates nonspecific immunity and increases the protective functions of the body. Imunolac is a preparation of enzymatic hydrolysis of the cell wall of Lactobacillus, activating the cellular and humoral factors of non-specific animal resistance. To achieve this goal, the following tasks were set: to find out the microclimate condition and sanitary regime in the boxes in which the experimental animals were kept; – to study the influence of immunostimulating drugs on the growth and intensity of the test pigs, their safety; to study the dynamics of immunological parameters (circulating immune complex (CIC), T-and B-lymphocytes), the content of immunoglobulins (Jg G, Jg M and Jg A) while using RBS and Imunolac. The research was carried out in the pedigree plant «Stepnoy» of the Zaporozhye region on pigs of the Large white breed × Landras. Piglets of the control group were injected with 0.9% sodium chloride solution at a dose of 1 ml/head. During the experiment, the microclimate was monitored for temperature, relative humidity, air speed, carbon dioxide, ammonia, air contamination with microflora. Cellular indices were determined from the ratio of neutrophils to E. coli according to VG Gostivu, 1956, bactericidal activity of blood serum (BASK) – according to the method of O.V. Smirnova and TA. Kuzmenoy, 1966, lysozyme activity of blood serum (LASK) according to V. Dorofeychuk, 1968. The content of T lymphocytes was determined according to M. Jondal, 1973, B-lymphocytes – according to N.S. When piglets were grown at the temperature lower than 3,5–8 °C, humidity – by 5–8% higher, the parameters of NH3 and CO2 higher by 0.8–1.2%, the contamination microflora was twice as much as recommended by the sanitary norms the genetic productive potential of the animals is not fully realized, while – the highest daily average weight gain was in the pigs, which were injected intramuscularly with RBS growth stimulant. They exceeded the animals from the control group on the 20th and 30th days of the experiment – by 24.3% and 14.4%, live weight – by 15.3% (P < 0.05). The growth rate in the animals that were injected with imunolac was less expressed; the diseases with the symptoms of dyspepsia and bronchopneumonia were registered in 5–10% of the pigs from the experimental groups that received RBS and imunolac that is 10–12 times less as compared to the control group; in the pigs from the experimental group 1, the BASK was at the level of the average values of 56.52 ± 2.03%, from the experimental group 2 – 59.48 ± 1.80%, by 5.2% higher (P < 0.05); LASK indices in the animals of the experimental group tended to increase but the differences were not trustworthy (P < 0.5); the cell indices of resistance in the pigs that received RBS were higher: the phagocytic activity of blood serum – by 4.3% (P < 0.05), phagocytic number – by 9.7% (P <0.05); the highest concentration of immunoglobulin of class Jg G (21.82 ± 0.3 mg/ml) was revealed in the animals that received RBS preparations, the concentration of the above immunoglobulins was slightly below – 19.86 ± 0.18 mg/ml in the pigs that received imunolac (0–1). For immunoglobulins of class Jg M and Jg A, the fluctuations  between the experimental groups were within the limits of 2.23 ± 0.01 and 2.36 ± 0.09 mg/ml.

The purpose of research is increase in economically useful qualities of piglets weaned with co-feeding of the sorbent Kovelos-Sorb and probiotic Sporotermin. Weanling piglets produced in 2 months of age. Duration of the experiment was 60 days, on reaching the age of 120 days. The first control group received a basic diet, the second experimental group – the basic diet and probiotic Sporotermin in the amount of 0.1% by weight of the feed, the third experimental group – the basic diet and sorbent Kovelos-Sorb in the amount of 0.1% by weight of the feed, the fourth test group – the basic diet, Sporotermin 0.1 by weight of the feed and Kovelos-Sorb 0.1% by weight of the feed. The studies found that the body weight of piglets at the age of 120 days in the second, third and fourth groups were higher by 4.1; 6.6 and 10.9%, respectively, relative to the first live weight of pigs group. It has also been found to increase average daily gain of 7.1; 11.7 and 19.4%, respectively, relative growth of the first group of piglets. Feed costs decreased by 3.7-16.3% in the experimental group, fed by the sorbent and the probiotic and probiotic sorbent together. With increasing body weight, the increase and feed decrease, there was an increase of beef entering the 0.4-1.6% relative to slaughter pigs release of the first group. Based on these data, we recommend the combined using of probiotic Sporoderm and sorbent Cavelos-Sorb, respectively, in the amount of 0.1% by weight of the feed for piglets-weaned at 2 months of age.

The effect of Phytoplus on weaned piglets was studied for the period of 50 days in 2018 and the influence of Algasol preparation on pregnant sows was investigated during 60 days in 2017. Phytoplus contains extracts from Rhaponticum carthamoides, Serratula coronate, and Filipendula ulmaria plants. It was administered daily, against the background of the control, into the diet of piglets aged from 40 to 90 days (n = 50 in the group): group No. 1 ‒ 0.3 g; group No. 2 ‒ 0.5 g; group No. 3 ‒ 1 gram per head per day. When Phytoplus was used, livability of piglets in all groups was 100%, the incidence in the experimental groups (2.3±0.3 heads) was 1.6-2.5 times lower than in the control group (5 heads). The live weight in the experimental groups (48,3±5,9 ‒ 51,4±7,5 кг) exceeded the result in the control group (41.8 kg) by 15-22%, and the intensity of the average daily weight gain by 24-33% (764,0±3,0 g ‒ 818,0±4,3 g against 616±2,2 g). Significant difference (P <0.05) was observed in piglets of the 3rd group, where AST increased, as compared with the beginning of the experiment, by 21.3% (from 15.9±0.6 to 19.3±0.5 units / l), and ALT by 12% (from 23.3±1.1 to 26.1 ± 2.1 units / l) and in the 2nd group where ALT increased by 46% (from 17.7±1.3 to 23.9±1.3 units /l). Algasol is a preparation from the extracts of brown algae and licorice roots. The experiment was carried out on nursing sows of large white breed pigs (2 groups of 48 animals each) when farrowing and before weaning piglets at 28 days of age. Sows of the experimental group were given Algasol daily at a dose of 50 ml per head. Algasol optimized their overall condition. The sows of the experimental group yielded 2% (572 pigs) more than in the control (561 pigs), the stillbirth decreased by 8% (23 vs. 25 animals). The death rate in the experiment was 2.1 times lower than in the control (17 vs. 8 goals), and livability was 98.5%. It has been established that Phytoplus and Algasol exert influence on the adaptive-compensatory reactions in the body of piglets and sows, that is proved by an increase in weight gain, livability of the young, and rise in the milk yield of the sows.

The paper presents the results of the influence of enzyme (ferment) preparations in various combinations on the dynamics of growth and development and slaughter qualities of ducklings. The scientific and economic experience was conducted in the Chuvash Republic. For carrying out experiments 3 groups of ducklings on 50 heads in everyone were selected and formed. Ducklings of the 1st experimental group received enzyme preparations amylosubtilin in the amount of 0.05 kg/t and protosubtilin in the amount of 0.05 kg/t during the entire period of growing together with feed. Ducklings for the 2nd experimental group of compound feed were enriched with enzyme preparations amylosubtilin in the amount of 0.1 kg/t and celloviridin in the amount of 0.075 kg/t. It was found that ducklings receiving enzyme preparations in addition to feed had increased growth energy throughout the experiment. By the end of the experiment, the live weight of ducks of the control group was 3,424 kg, the first experimental group receiving in addition to the feed enzyme preparations amylosubtilin in an amount of 0.05 kg/t and protosubtilin in the amount of 0.05 kg/t – 3,712 lbs. In the second experimental group, where the ducks advanced to the feed received enzyme preparations amylosubtilin in the amount of 0.1 kg/t and celloviridin in the amount of 0.075 kg/t, live weight to the end of the experiment amounted to 3,804 kg. The average daily live weight gain of animals in the control group was 53.52 g, and in the first experimental group - 58,10 g, in the second one - 59,56 g. The inclusion of a mixture of enzyme preparations with a compound feed of the experimental animals have contributed to the increase in body length compared to the control on average by 0.9 cm and 1.6 cm, length of tarsus by 2.5 cm and 4.3 cm, chest girth by 1.8 cm and 2.5 cm, respectively. The increased productivity of ducklings in growth was reflected in the reduction of feed costs and unit costs, which contributed to multiplying profits in the experimental groups.
