Pork production in modern conditions associated with the use of feed and dietary supplements as part of diets, because without them to provide animals essential nutrients almost impossible. Especially for little Ingredient grain rations. Therefore have resorted to creating new PVMA. These concerns and PVMA Intermiks PS – 7.5% and Intermiks LS – 20% – according to gestation and lactating sows. So were conducting research on the influence of feeding PVMA Intermiks sows in different periods of the reproductive cycle of feed digestibility and metabolism of nitrogen, calcium and phosphorus in their piglets weaned at 28 days age. Research groups conducting two–analogues pigs of large white breed balance method, under which the pigs were kept in individual cages and accounted for eight days consumed feed, feces and urine color. The live weight per head was 9 kg. Sows experimental group during 85 days gestating 7.5% by weight was replaced grain mix PVMA Intermiks PS, and next to farrowing and weaning piglets at 28 days age, replaced 20% concentrated feed on PVMA Intermiks LS. Sows in the control group were kept in complete feed appropriate. After all born piglets up to 14 days eating a special supplement Intermiks SP «Bambino» – 25%, and from 14 to 28 days – Intermiks SP – 25%. Studies have shown that feeding sows PVMA Intermiks increases performance polycarpous 10.8% weight in the pig–breeding nests by 25.3% and 13.3% macrocarpa. The weight of a piglet at birth the control and the experimental groups was 1.05 and 1.19 kg and at weaning at 28 days of life – 8.52 and 9,1 kg. Piglets from sows receiving PVMA Intermiks had higher levels of digestibility of crude oil (3.3%) and fiber (to 5.37%). No significant difference was obtained for the digestibility of dry, organic matter and protein compared to piglets from sows with complete feed in the diet. In the experimental pigs tends to increase the number of nitrogen retained in the body (14.5 %) and from the accepted and digested (by 4.4 and 6.0%). Terms feeding lactating sows gestation and no likely impact on calcium and phosphorus in pigs weaned at 28 days 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.

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.

SUMMARYThe carcass characteristics of young adult female pigs (gilts) slaughtered after weaning their first litters have been investigated using three groups of 19 Landrace × (Landrace×Large White) gilts. In two treatment groups gilts were mated at their pubertal oestrus and suckled their piglets for 5 to 11 and 35 to 42 days respectively. These gilts were slaughtered on average 10 days after weaning. A third control group consisted of unmated gilts slaughtered at 118 kg live weight.There was no significant difference in the killing-out percentage for the three groups. The carcasses of the gilts which farrowed contained significantly less fat (P<0·001) than those of the unmated controls. The carcasses of the farrowed gilts had significantly lighter middle sections (P<0·001) and significantly heavier shoulders (P<0·001) than the controls.Despite the variations in tissue yield and distribution, the yield of prime joints for the gilts which had farrowed was only 0·62 percentage units less than that of the controls.No commercially significant variations between groups in meat quality were observed.

The purpose of the research is to increase the effectiveness of the supplement Reasil on the growth of milk-fed calves. For the scientific and economic experience, three groups of calves were formed (control, 1 and 2 experi-enced). Groups of animals of 10 heads were formed according to the principle of analogues. The indicators of live weight, growth and blood of calves were studied after Reasil use in a diet: Reasil HumicVet as a liquid form, and Reasil Humic Health – reduced to powder. In the experiment, animals of a black-and-white breed were used. The Reasil feeding in the diet contributed to an increase in the live weight of milk-fed calves in the 1-st and the 2-nd experimental groups at two months of age by 5.65 and 5.48 kg (or by 7.4 and 7.2%), respectively, compared to the indicator of the control group analogues. The average daily growth of calves of the experimental groups exceeded this indicator of control animals by 96 and 82 g, respectively. The blood of calves of the 1st and 2nd experimental groups, showed that hematoglobin was higher by 15.7 and 11.4%, red blood cells – by 16.5 and 15.1%, and the alkaline reserve – by 5.2%, compared with blood of calves from the control group, which indicates the activation of metabolic processes in the body. The total protein amount in the blood serum of animals from the experimental groups increased by 8.4 and 5.9% respectively, compared to the tests of calves from the control group. The albu-min content of animals of the 1st experimental group tested was higher by 5.3%; from the 2nd experimental group there was no significant difference compared to the control. The number of gamma-globulins in the blood of ani-mals of the experimental groups increased, which indicates an increase in defense reaction of animals. The con-tent of calcium in the blood serum of calves from the experimental groups was higher by 8.3 and 5.9%, phosphorus – by 4.8 and 2.4%, which indicates a more effective use of these mineral elements.

Three experiments were carried out to improve the meat productivity of pigs of Large White (LW) breed of russian selection by different variants of crossing with the Yorkshire (Y) breed of canadian selection. There were no significant differences between the groups in terms of reproductive qualities. Two-breed pigs (LW x Y) grew more intensively and the live weight of the piglet at the 30 days was 8,7 kg, which is higher than in the other groups with a significant difference (P <0,05). When the live weight of 100 kg was reached, the вackfat thickness of the fat over 6-7 thoracic vertebrae was 26,3 mm compared to 30,7 mm in purebred pigs of the LW of the breed (P <0,001), the area of the muscular eye was respectively 45,1 cm 2 and 30,6 cm 2 (P <0,001). In the fourth generation of reproductive and absorbent crossing of pigs of LW and Y of breeds, the thickness of the fat on the carcasses of pigs was 21,2 mm (Р < 0.001), which is 30-39 % less than for the LW carcasses, the area of the muscular eye was 44 mm. In three-breed hybrids (LW x D) x L, the age of reaching 100kg was less by 12,5 days (P <0,01), the thickness of the fat was 23,6 mm, that is, it was 11,4 mm less (P < 0,001) in comparison with the control group. The replacement pigs obtained from the absorbent crossing (LW x Y) x Y showed the best results for the вackfat thickness - 19,2 mm, but they were inferior to the purebred Y (13,0 mm) (P <0,001). In the sows of this combination, 11,6 piglets were born alive, the number of piglets at weaning was 10,6, the weight of the nest in the 30-day was 78,7 kg. Differences in the frequency of occurrence of certain antigenic factors of blood in animals of different combinations of breeds are revealed. In animals that have the EAE allele edf, a higher growth rate is revealed, but thicker the backfat.

Эффективность применения кормовых пребиотических добавок в рационах телят возрастает в ранний (молочный) период их выращивания, когда происходит изменение трофических процессов, способов переработки пластических веществ, синхронизация биологических ритмов роста, развитие органов и систем организма, повышение чувствительности клеток к стимулирующим и тормозящим воздействиям. Цель работы заключалась в испытании кормовой пребиотической добавки, разработанной для профилактики и лечения диареи телят в молочный период выращивания. Опытная группа телят в период с 3- до 60-суточного возраста получала пребиотическую добавку в виде болюсов следующего состава (г): чистотел большой – 3,5; ромашка лекарственная – 3,5; куркума длинная – 0,6; аскорбиновая кислота – 1,2; фруктоза – 1,2; энтеросорбент – 2,0; сахар – 3,0; зерновая мука – 1,0. Суточная доза добавки, в зависимости от возраста и живой массы, составляла 12–16 г. В качестве энтеросорбента использовался глауконит Бондарского месторождения. В научно-производственном опыте установлено, что уже через два месяца экспериментального кормления отмечено статистически значимое различие в живой массе между группами, которое составило 2,1 кг в пользу опытных животных. Макроскопический анализ кала животных обеих групп показал, что консистенция, цвет и запах практически были одинаковыми, pH – слабокислая (5,23–5,22), примеси (кишечные паразиты и др.) отсутствовали, из чего следует, что секреторная и всасывающая функция желудочно-кишечного тракта у телят были нормальными. В контрольной группе у двух телят в течение первой недели после рождения были зафиксированы признаки нарушения функции желудочно-кишечного тракта (ЖКТ), которое сопровождалось диареей. Продолжительность болезни каждого телёнка составляла в среднем 4 суток. В целом, скармливание фитопребиотика в течение первых месяцев жизни телят оказало лечебное действие на простую диарею, обеспечило нормальное функционирование микробиоты кишечника, стимулировало увеличение среднесуточных приростов живой массы на 5%. The effectiveness of the use of prebiotic food supplements in diets of calves increases in the early (dairy) period of their growing when there is a change in trophic processes, methods of processing plastic substances, synchronization of biological growth rhythms, the development of organs and systems of the body, increasing the sensitivity of cells to stimulating and inhibitory effects. The purpose of the work was to test a food prebiotic supplement developed for the prevention and treatment of calf diarrhea during the dairy period of growing. Test group of calves from 3 to 60 days old received a prebiotic supplement in the form of boluses of the following composition (g): Chelidonium majus – 3.5; Matricaria chamomilla – 3.5; Curcuma longa – 0.6; ascorbic acid – 1.2; fructose – 1.2; enterosorbent – 2.0; sugar – 3.0; grain flour – 1.0. The daily dose of the supplement depending on age and live weight was 12–16 g. Glauconite of the Bondarsky deposit was used as an enterosorbent. In the research and production experiment it was found that after two months of experimental feeding a statistically significant difference in live weight between the groups was noted which amounted to 2.1 kg in favor of the experimental animals. Macroscopic analysis of feces in animals of both groups showed that the consistency, color and smell were almost the same, pH was slightly acidic (5.23–5.22), impurities (intestinal parasites, etc.) were absent which implies that the secretory and absorbing function the gastrointestinal tract in calves was normal. In the control group two calves during the first week after birth showed signs of a derangement of the function of the gastrointestinal tract (GIT) which was accompanied by diarrhea. The duration of disease of each calf averaged 4 days. In general feeding a phytoprebiotic during the first months of life of calves had a therapeutic effect on simple diarrhea, ensured the normal functioning of the intestinal microbiota and stimulated an increase in daily live weight gain by 5%.

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 difference in feeding was due to different levels of calcium and phosphorus in the feed for experimental groups. In the beginning of the experiment the experimental quail were similar regards live weight while in the end we did not detect significant difference in their mass. Nevertheless, we observed little decrease in live weight with increasing of phosphorus up to 1.4 % and calcium up to 3.5 %. We fixed that water content in the quail skeletons from Group 4, 5 and 6th study groups (calcium 4.0 %, phosphorus 0.8, 1,1 and 1,4 % respectively) were smaller in comparison with quails from Control, Group 2 and 3 (calcium content 3.5 % with the same level of phosphorus). We also determined increasing of dry matter content in the skeleton by 2.5 – 2.8 % while increasing the content of calcium and phosphorus in mixed fodder of quails-hens (Group 4, 5 and 6). The phosphorus content in quail skeleton depended on the level of phosphorus in the mixed fodder and can be up to 0.39-0.66 % in the bones. The simultaneous increase in the level of phosphorus and calcium in mixed fodder of experimental groups was accompanied by increase in the concentration of calcium and magnesium in the quail skeleton by 0.85–0.87 and 0.01–0.07 per cent respectively.</p>

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.
