Improving the efficiency of pig farming requires biologically complete feeding in accordance with the age, physiological and sexual characteristics of animals based on the knowledge of composition and nutritional value. The health and productivity of animals depends on the use of protein, fat, carbohydrates and minerals, and high-quality vitamins. Traditional feed does not provide animals with a sufficient and optimal ratio of minerals and vitamins. One of the factors providing young pigs with these nutrients may be the inclusion of the DKB vitamin-mineral energy supplement in the diet. The article analyzes the influence of DKB on the productivity of young pigs. The aim of the study was to justify an increase in productivity indicators of large white pigs feeding with DKB. In order to trace the impact of DKB on the productivity of pigs, we took into account the change in their live weight. During the experiment (60 days), 54 kg of the vitamin-mineral complex worth 3300 rubles was spent on the 20 piglets of the experimental group. This entailed an increase in the total costs. The results of the study indicate a positive effect of the additive on the dynamics and growth rate of the piglets of the experimental group and on the cost of feed and nutrients, which favorably affects the profitability and economic efficiency of pork production.

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.

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.

Selenium plays an important role for maintaining complex and adequate nutrition of fattened young pigs. It also has a big biological importance to maintain growth and health, as well as for biochemical and physiological processes This study presents the results of a production experiment to determine the effect of organic and inorganic forms of selenium on growth indicators, immunohematological blood parameters and slaughter qualities of fattened pigs in period I and II. Test feeding with various forms of selenium has been implemented with two groups of analogs (N = 60; n = 30), taking into account age and live weight. The experiment was conducted on castrates of large white breed, which were divided into two groups of 30 heads each following the principle of analogues (taking into account their age, live weight). The studied fattened pigs received standard complete feeds of the SK-5 and SK-6 types for a period of 105 days. Growing pigs were fed with organic selenium for 20 mg/kg as part of the feed 64 mixture per head in the first and second period of fattening, while the animals of the control group were fed with 0.3 mg/kg of the inorganic form of selenium. Including a chelated form of selenium in the complete feed of castrates at the rate established in the course of scientific and economic studies has led to 757 g of average daily gain, which is 8.1% more as compared to the control group. The concentration of red blood cells in the blood of growing pigs fed with 20 mg/kg of selenium chelate increased by 6.3%, hemoglobin – by 2.4%, and white blood cells – by 7.1% as compared to the control. Feeding organic selenium to fattened young pigs contributed to a significant increase in specific units of protein activity by 38.65% (p < 0.01), BASC – by 7.63%, as well as lysis – by 40.06% (p < 0.05), and phagocytic activity by 3.33% in blood serum as compared to the control. The half-carcasses of hogs who had received fed rations including selenium chelate fetured slaughter weight and slaughter yield, respectively, higher – by 6.4 and 0.6% as compared with the control analogues. The use of the established norm of organic selenium in the diets of fattened young pigs according to the results of production testing is economically profitable and contributes to a per-head profit of 420 rubles.

The purpose of the researches was to study the influence of different doses of smectic kizelgur and calf skim milk replacer in the recipes of compound feed for young pigs under the conditions of industrial pork production technology. The experimental part of the work has been performed under the conditions of the pig complex of LLC “BMPK” in the Karachevsky area in the Bryansk region. The research materials were compound feed for young pigs on fattening in the inclusion of different doses of smectic kizelgur. The infl uence of feeding compound feed with different doses of smectic kizelgur and calf skim milk replacer to young pigs on productivity, digestibility of nutrients and use of nitrogen, morphological and biochemical parameters of blood, fattening and meat traits of young pigs has been studied. Effective recipes for feeding compound feeds to young pigs prepared with the inclusion of different doses of smectic kizelgur and calf skim milk replacer have been identified. The data have been obtained from the first experiment of young pigs when them fed compound feed with different doses of smectic kizelgur; it has been followed that at the end of fattening the biggest live weight of gilts had in the 4th experimental group fed compound feed, which included 3 % smectic kizelgur. The influence of the additive on changes in live weight and daily gains when adding smectic kizelgur to compound feed in doses of 1,5 and 2,0 % was less, but the trend to increase these indicators over the period of fattening has remained. In the second experiment young pigs have been fed by compound feed, which included different doses of smectic kizelgur and calf skim milk replacer the average daily gain in live weight was higher in the 3rd experimental group, where they fed compound feed with the addition of 2,5 % smectic kizelgur and 2,5 % calf skim milk replacer by 2,2 %, than in the control group. The highest efficiency has been also obtained in the 3rd experimental group, where the monetary revenue has been received by 2160 rubles more in comparison with the control group of pigs.

The effect of the plant ecdysteroid-containing preparation of Leuzea extract on the metabolism and productivity of barrows (three-breed crossbreeds Landrace × large white × Duroc) during fattening on low-protein diets enriched with essential amino acids from 130 to 212 days old was studied for the first time. In the control and experimental groups, a low-protein barley-wheat diet with the addition of essential amino acids contained (g / kg) crude protein - 108 g, metabolic energy - 12.5 MJ, lysine - 7.6 g, threonine - 5.4 g, methionine - 5.2 g. In the experimental group, liquid extract of leuzea was introduced into the feed, at the rate of 190 mg / kg. Feeding the barrows during the fattening period of the leuzea extract contributed to an increase in the efficiency of the use of nutrients in biosynthetic processes in animals. In the barrows of the experimental group, the concentrations of total protein (P≤0.05), albumin (P≤0.05), creatinine (P≤0.05), lactate dehydrogenase, creatine kinase, alkaline phosphatase activity at a lower level were statistically significantly higher urea (16.1%, P≤0.05) and glucose (P≤0.05). In the experimental group, during the period of fattening, the average daily gain in live weight was higher (by 10.2%, P≤0.05), the yield in the carcass of muscle tissue (P≤0.05), the indices of lean and meatiness, and lower the cost of feed (P≤ 0.05), crude protein (P≤0.05) and exchange energy (P≤0.05) per 1 kg of gain in live weight, output of subcutaneous adipose tissue and internal fat in comparison with the control. It was concluded that the use of a leuzea extract containing phytoecdysteroids, while feeding low-protein diets enriched with lysine, methionine and threonine, corrects metabolic processes, stimulating the biosynthesis of meat components, and thereby contributes to an increase in the productivity of barrows during fattening.

The analysis of the therapeutic efficacy of a new medical and prophylactic drug on piglets of Large White breed crossed with Duroc was carried out. The experiment was conducted in the conditions of a pig-breeding farm in theTrans-BaikalTerritoryin 2019, 2020. Experimental animals were treated with a preparation based on dry extracts of magnolia vine, wild rose, bird cherry, chamomile, and eleutherococcus rhizomes. For the experiment, three groups of newborn pigs (n = 30) with signs of gastrointestinal tract disorders were formed. The drug was administered to piglets for 10 days according to two regimens: the 1st experimental group was given the drug orally at a dose of 6 ml/kg of live weight once a day; the 2nd experimental group – at a dose of 6 ml/kg of live weight 2 times a day with an interval of 12 hours. The control group was injected with a prebiotic at a dose of 10 ml/kg (1x106 CFU/10 mg) once a day. The animals were assessed on a daily basis for their clinical status (temperature, pulse, respiration, level of dehydration according to skin turgor, intensity of reflexes, state of feces). Recovery in the 1st group was observed on the 4th day, in the 2nd group on the 2nd day. The animals of the control group suff       a severe disease, the death rate was 60%, the surviving animals recovered on the 10th day. In animals of the 2nd group, there was an increase in lymphocyte cells by 34.5%, erythrocytes – by 18.1%, hemoglobin – by 8.1%, hematocrit – by 13.9%. The biochemical analysis of the blood serum of piglets showed a positive growth dynamics of total protein by 12.1%, albumin – by 17.1%, globulins – by 6.2%. The most effective regimen of treating pigs with the herbal preparation proved to be the one used in the 2nd experimental group. The use of the drug according to the recommended treatment regimen will allow pig farms to ensure high survival rate of young pigs, increase their weight gain and get environmentally friendly pig products.

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 article highlights the problem of finding optimal variants of breeding process in a herd of pigs at purebred and crossbred selection. For this purpose, the control and two experimental groups were formed: ♀ Pietrain × ♂ Pietrain (control), ♀ (Pietrain × Large White) × ♂ Large White (first experimental group), ♀ (Pietrain × Durok) × ♂ Pitren (second experimental group). The analysis of the animals performance in these groups was carried out in 40, 30 and 35 parities, respectively. The research was conducted on the basis of PE «Maglevovany M.I.» in the Donetsk region. It has been established that the higher level of reproductive characteristics have sows of first experimental group, which have heredity of Large White breed, this breed is traditionally considered as a maternal form in cross-breeding schemes. For instance, their litter size at birth is higher than the same indicator in the control and second experimental group (plus 0,5, P<0,05, and 0,3 piglets, respectively); by the litter size at weaning at 28 days (plus 1,6, P<0,001, and 0,6 piglets); by the litter size at 2 months (plus 1,6, P<0,001, and 0,4 piglets). The highest piglet survival at the age of 2 months was in the litters, whose ancestor were boars of Pietrain breed (second experimental group) − plus 3,6 and 2,3 %, respectively, compered to purebred piglets of Pietrain breed and the first experimental group. For such complex indexes as the litter weight at weaning and litter weight at 2 months the first experimental group had an advantage of 18,1 kg (P<0,001) and 31,1 kg (P<0,001) over the control group (purebred Pietrain) and 5,4 kg and 7,6 kg − over the second experimental group. However, the average piglet weight of sows of second experimental group both at 28 days and at 2 months are equal to the average piglet weight of the same age of the first experimental group. The piglets, which are descendants of boars of meat breeds Duroc and Pietrain show a tendency to the faster growth even in an early age. The avarage live weight of pigs of the second experimental group at the age of 100 days and 7 months is higher compared to avarage live weight of pigs of the same age of the control and the first experimental groups – plus 8,5–21,7 kg (P<0,01 for the second experimental group) and 4,4–13,5 kg (P<0,001 for the second experimental group), respectively. At the age of 100 days, the maximum average daily gain was obtained in the second experimental group with an advantage of 190 g (P<0,001) compared to control group and 115 g (P<0,001) compared to the first experimental group. It is obvious that hybrids with the faster growth, which were obtained through crossbreeding ♀ (Pietrain × Duroc) × ♂ Pietrain reach a live weight of 100 kg in a shorter period: they need less time needed to reach 100 kg of live weight – 32 days less (P<0,001 ) compared to purebred animals of Pietrain breed (control group) and 18 days less (P<0,001) compared to hybrids ♀ (Pietrain × Large White) × ♂ Large White (the first control group). By such an indicator as the fat thickness the hybrids of the second experimental group dominate by purebred pigs of the same age of the control group (minus 0,2 mm), that characterize the low ability of meat breed for getting fat. The fat thickness of hybrids of the second experimental group was less by 0,9 mm (P<0,001) compared to the pigs of the first experimental group. Thus, in this herd in order to improve the reproductive qualities of sows, it is suggested to use the crossbreeding scheme ♀ (Pietrain × Large White) × ♂ Large White and to improve the fattening qualities of young animals the optimal is scheme of crossbreeding ♀ (Pietrain × Duroc) × ♂ Pietrain. Key words: pigs, Pietrain, Large White, Duroc, purebred and crossbred selection, reproductive and fattening qualities.

The purpose of the research was to elucidate the eff ect of compound feed containing an experimental concentrate intended to improve the performance of pork, when it is used at the fi nal stage of fattening pigs. The composition of the concentrate (%) was: vitamin E-0,32; vitamin D3 – 0,30; vitamin C - 0,30; vitamin B4 – 1,56; vitamin B12 – 0,004; betaine – 10,00; bentonite – 77,166; soy fl our (fi ller) – 10,00. Activity of drugs was: vitamin E - 50,0 %; D3 – 15,0 thousand. IU in 1 g; B4 -60,0 %; B12 – 1,0 %; Omec J - 2,0 %; selenium-KI – 0,2 %. Testing of the concentrate under production conditions has been carried out on two groups of pigs (n=24.) of Large White breed. The control group of animals has been received farm’s compound feed and experimental group has been received together with the compound feed experimental concentrate in the amount of 1,0 % within 10 days prior to slaughter. The average live weight of pigs when the enter to the experiment amounted to 95,7–95,8 kg when the fi nish it was 114,1–114,7 kg. Gut microbiocenosis and some biochemical parameters of pig meat have been studied. The average daily gain in live weight in pigs receiving compound feed containing concentrate increased by 2,8 %. There was an improvement in the biological value of pork protein due to the higher content of essential amino acids in it by 0,44 %. Meat samples have been obtained from animals from the experimental group exceeded the control ones by the amount of tryptophan, leucine, isoleucine in them signifi cantly. Protein-quality indicator of meat from animals of the experimental group exceeded the control samples by 3,35 units. The moisture-binding capacity of meat from animals from the experimental group was higher by 6,0 % (P < 0,05), and the color intensity by 3,0 units of extinction (P < 0,05), which is consistent with a higher hemoglobin content in the blood by 1,5 g/l. The meat of experimental animals has been characterized by the increased content of ribofl avin, biotin and folic acid. Tasting evaluation of meat and broth gave positive results.
