Pork production today is based on intensive management of the industry and quality improvement of breeds. In our country, there are changes in the breed structure in the direction of the predominant focus on breeds of meat productivity. In this regard, an important place is given to pigs of the Duroc breed, which have been used in Ukraine for a long time. Numerous studies have shown that under the same conditions of feeding, keeping fattening and meat qualities of pigs of different breeds and interbreed combinations at different weight conditions are not the same. The purpose of the work is to study the fattening and meat qualities of the intra-breed type of Duroc pigs of the Ukrainian selection «Stepovy» (DUSS) with different methods of breeding during fattening to high weight conditions. The study of fattening and meat qualities of pigs of interbreed type «Stepovy», Large White foreign (LW (FS)) and Landrace of French (L (FS)) selection took place in the conditions of SVC «Agrofirm «Mig-Service-Agro» of the Mykolaiv region. A comparative assessment of fattening and meat qualities of young animals of the following combinations: I – DUSS×♂DUSS – control group, II – ♀LW(ZS)×♂DUSS, III – ♀DUSS×♂LW(ZS), IV – ♀L(FS)×♂DUSS, V – ♀DUSS×♂L(FS) – experimental groups, when animals reach a live weight of 100, 120 and 140 kg. The highest fattening rates for three variants of fattening had young animals obtained from a combination of sows of the interbreed type «Stepovy» with boars of the Landrace breed. The expediency of fattening these pigs to high weight conditions was noted, as they maintained a high growth rate during fattening to a live weight of 140 kg. The greatest value of the complex index of fattening and meat qualities had animals of the V experimental group in the range of 211.9-203.6. When the animals reached a live weight of 100-140 kg, the lowest value of this indicator was characterized by animals of the II experimental group. It was found that the relative rate of meat yield at the slaughter of 100-140 kg was different and depended on the genotype of the animals and was in terms of groups – 64.12–53.81 %. After the meat came out of the carcass, purebred animals of the interbreed type of the Duroc breed of the Ukrainian selection «Stepovy» (I control group), local young growth of a combination ♀DUSS×♂L(FS) were better, at them at slaughter in 100–140 kg relative exit m was: 63.90–56.14 % and 64.12–57.53 %, 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.

Relevance. Modern turkey crosses have a genetically determined high growth rate. These farm birds are very sensitive to even minor fluctuations in their diet, are susceptible to a deficiency of amino acids, protein, mineral elements and vitamins, which can contribute to a decrease in their productivity, the development of pathological processes and diseases. The use of modern technologies and scientific achievements has made it possible to prepare a new product — modified zeolite. This natural mineral is already free of impurities and microbes, with open pore windows, has a high ability to selectively exchange, and is obtained by various methods of activating zeolite in industrial conditions. At the same time, Ulyanovsk specialists have mastered the technology of enriching modified zeolite with useful substances.Methods. The aim of the work was to study the effect on the body of turkeys and the level of their productivity of additives based on modified zeolite enriched with amino acids. The experiment was organized for 60 days on 250 turkeys of the breed Hybrid Cread-mayker aged 55–60 days in the conditions of the Ulyanovsk region. The control group received the main ration (MR), the experimental group was given once a day in addition to the MR in the morning feeding in a mixture with mixed feed 5% additives of modified zeolite enriched with amino acids.Results. The inclusion of a supplement based on modified zeolite enriched with amino acids in the diet of turkeys does not have a negative effect on the hematological parameters of their blood, all indicators corresponded to the physiological norm. During the experiment in the 2nd group, the live weight of poultry was obtained larger by 8.70%, which amounted to 12,296 kg, respectively, more profit was obtained from the sale of turkey meat, total revenue was 133,210, and additional profit was 27,960 rubles, 2.41 rubles of profit was received for 1 ruble of costs. Тhe data indicate the normalization of mineral homeostasis in the body of turkeys and better absorption of nutrients in the feed diet.

The purpose of the present study was to investigate the effects of feeding peat as a supplement in the period after weaning on the performance and health status of pigs. Also to assess the risk of the development of tuberculous lesions in the lymph nodes and parenchymatous organs, caused by conditionally pathogenic mycobacteria present in peat. Twenty Large White&nbsp;&times;&nbsp;Landrace pigs in equal numbers of barrows and gilts (mean live weight 18.0&nbsp;&plusmn;&nbsp;1.7&nbsp;kg) were used in the experiment. The experimental group was fed a diet containing commercial underground peat in the dose of 80&nbsp;g peat/kg dry matter for 30 days. Subsequently, they were fed an identical diet with the control group without peat for 60 days. A short-time feeding peat did not significantly affect the growth and performance of pigs. From day 21, a statistically highly significant (P &lt; 0.01) increase in the consumption of the experimental diet was recorded, however, without a positive effect on the growth of experimental animals. The conversion of the peat containing diet was comparable to the conversion of the control diet. It follows from the results of biochemical analysis of blood that peat feeding for 30 days did not adversely affect the metabolic profile and health status of experimental animals. No tuberculous or tuberculoid lesions in lymph nodes or parenchymatous organs were detected in any of 20 slaughtered animals. Despite that, mycobacteria were isolated from 10 (25.0%) tissues of 5 (50.0%) pigs from the experimental group. One isolate was identified as Mycobacterium avium subsp. hominissuis (IS901&ndash; and IS1245+). Seven of nine isolates were determined as conditionally pathogenic atypical mycobacteria: M.&nbsp;fortuitum (n&nbsp;=&nbsp;2) and M.&nbsp;xenopi (n&nbsp;=&nbsp;5). It follows from the present results that feeding of a peat supplemented diet to pigs may be considered as economically non-effective and due to the findings of mycobacteria as risky.

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 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 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.

Задача повышения экономической эффективности кормления крупного рогатого скота, получения здоровых животных с высокой продуктивностью может быть решена введением в рацион кормления биологически активной добавки. Исследована технология кормления молодняка крупного рогатого скота с использованием отечественной кормовой добавки на основе микроэлементов в виде гидроксид полимальтозных и хелатных комплексов. В состав добавки входят медь, кобальт, селен, йод, марганец в виде амминоатов, цинк в хелатной форме глюконата, а также гидролизат растительного белка. Были сформированы две группы телят по 15 голов в соответствии с требованиями по подбору аналогов опытная и контрольная. Животным опытной группы в молоко вводили биодобавку (по 1 мл/кг живой массы), количество которой корректировалось в зависимости от изменения живой массы. При формировании групп живая масса подопытных телят была практически одинаковой. Но уже в месячном возрасте телята опытной группы по этому показателю превосходили контрольных на 1,5 кг, а в 2месячном возрасте на 4,1 кг, или на 5,3. Животные в опытной группе болели на 13 меньше по сравнению с контрольными. В целом за период исследования опытные телята превосходили контрольных по валовому приросту на 8,11. Установлено, что технология кормления молодняка крупного рогатого скота на основе оптимизации рационов с применением отечественной кормовой добавки, обладающей высокими биологическими свойствами, изготовленной из недорогих видов сырья, позволила обеспечить высокую интенсивность роста телят.The task of increasing the economic efficiency of feeding cattle, obtaining healthy animals with high productivity can be solved by introducing a biologically active supplement in the diet. The technology of feeding young cattle with the use of domestic feed additive based on microelements in the form of hydroxides of polymaltose and chelate complexes is studied. The composition of the additive includes copper, cobalt, selenium, iodine, manganese in the form of amino acids, zinc in the chelate form of gluconate as well as a gluten hydrolysate. Two groups of calves of 15 goals were formed in accordance with the requirements for the selection of analogues experimental and control ones. Dietary supplement (1 ml/kg of live weight) was introduced into milk of the experimental group animals the amount of which was adjusted depending on changes in live weight. During the formation of the groups the live weight of the experimental calves was practically the same. But already at the age of one month the calves of the experimental group exceeded the control one by 1.5 kg by this indicator and at 2 months of age by 4.1 kg or 5.3.
