The purpose of the work was a comprehensive evaluation of the productive and reproductive traits of sows of Yorkshire and Landrace breeds and their offspring under the conditions of a breeding enterprise in the Republic of Belarus. During the studies of reproductive traits, it has been revealed that the highest rate of prolificacy among the evaluated breeds was distinguished by Yorkshire sows 14,0 heads for farrowing. In terms of milk content, Landrace sows were 2,5 kg or 4,57 % higher than Yorkshire sows. In terms of weight and socket weight per piglet at weaning at the age of 28 days sows Landrace piglets surpassed herdmates Yorkshire breed in the weight of the litter by 6,8 %, and the weight of one pig by 0,9 %. It has been found by the results of the evaluation of fattening and meat qualities of purebred young pigs that the best parameters were different gilts of Landrace breeds, whose age achieve the live weight of 100 kg was 163,1 days, and average daily gain of live weight – 864,8 g, which was higher than in young pigs of Yorkshire breed by 1,8 day or 1,09 %, and 28,9 g or by 3,46 %. The young pigs of Landrace breed has been characterized by the best values of the area of the “eye of loin” – 73,8 cm² and the highest yield and amount of meat – 68,5 % and 24 kg, which was 11,4 cm² or 18,2 % and 0,4 kg or 3,5 abs.%, respectively, higher than the herdmates of Yorkshire breed. The results obtained indicate the possibility of using boars and sows of Landrace and Yorkshire breeds not only in breeding, but also in industrial pig breeding.

At the present stage of economic development of the Republic of Kazakhstan dairy cattle breeding should be competitive, highly productive and cost-effective, which contributes to ensuring the country’s independence from imports of dairy products. The formation of milk productivity of future cows begins with the preparation of cows for calving and the purposeful rearing of replacement young cattle, based on the achievements of scientific and technical progress, a systematic approach to the production of high-quality products. The researches have been carried out in the farm “Tauelsizdik” in the Eskeldinsky district in the Almaty region in the Republic of Kazakhstan. According to the results of the research, the average daily gain of live weight in 3 months of the post-embryonic period was 458,9±71,9 g in heifers have reared in narrow-sized pens, and 682,2±44,6 g in heifers have reared in group pens. At 3 months of age the live weight of heifers at rearing in narrow-sized pens has reached 76,5±2,5 kg in narrow-sized pens, and 98,3±1,7 kg in group pens (P < 0,001). The data of the experiment have convincingly shown the effectiveness of rearing heifers in group pens. The live weight of heifers at birth was 36,4±1,1 kg, at one month of age – 54,2±1,6 kg, at 2 months of age the live weight increased to 70,2±2,1 kg, at 3 months of age to 87,4±3,3 kg, at 4 months of age to 116,8±3,5 kg, at 5 months of age to 132,7±4,2 kg and at 6 months of age to 157,4±4,6 kg. The indices of lengthiness, chest, hip-chest and blockiness increased up with age, while the indices of high-leg and overgrown decreased down. For example, the lengthiness index has increased with age from 90 to 97 %, the chest index from 62 to 70, and the high-leg index has decreased from 59 to 54, overgrowth from 109 to 108 %.

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 article provides experimental data on the study of application of two probiotic additives - “Sitexflor - 1” and “SGOL-1-40”, included at different dosages in the diets for young pigs, on usage of the supplied nitrogen and their productivity. Such parameters were taken into account when forming the groups as: weaning time (60 and 45 days), preliminary feeding the mothers with the probiotic supplements under study during the suckling period. The results, characterizing the piglet productivity in case of application of “Sitexflor - 1”, convince that the most effective dose is 30 mg per head per day, which provided an average daily gain of 351 g, which is 7.3% more than the control, primarily due to greater nitrogen retention in the body (by 9.91%), but with lower consumption of energy feed units per 1 kg of gain -4.43 (by 11.4%). The results, characterizing the piglet productivity when applying “SGOL -1-40”, reliably confirm its most effective dosage of 2.5% of the dry matter of the diet, which provided an average daily gain of 404 g, which is 15% more than the control, due to greater nitrogen retention in their body (by 4%). Introduction of “SGOL -1-40” in the diet provided a significant reduction in the cost of energy feed units per 1 kg of gain in comparison with the control by 14.3%. The nitrogen balance in the body of young pigs was positive in both experiments, but the amount of nitrogen retained in the body was different. At the same time, even a greater amount of deposited nitrogen in animals in the first experiment did not allow to achieve the expected live weight increase, and in the second experiment, on the contrary, even surpassed it. Such data indicate that the supplied nitrogen with a diet enriched with a probiotic supplement was more effectively used in the body, exceeding the physiological level of its transformation into products.

The comprehensive evaluation of the productive traits of the initial genotypes of pigs in the creation of breeding herds using population selection methods has been carried out. Based on the results of evaluating the growth and development of breeding animals using the methods of index selection and DNA testing for the genes markers RYR1, ESR, IGF-2, MUC4 the genealogical structure of breeding herds has been formed on the basis of new stud lines of Belarusian stud type of pigs of Yorkshire breed. It has been found that sows of new lines had high reproduction rates: prolifi cacy was 11,6 piglets, milk capacity was 59,1 kg, number of piglets at weaning was 11,2 heads, and litter weight at weaning was 103,6 kg. The breeding herd of two new stud lines is represented by boars of the line Drug 6805 and Dobry 2313. The average productivity of boars-line continuers was: the age of reaching a live weight of 100 kg to 160 days, the average daily gain from birth to reaching the live weight of 100 kg was 636 g. At the age of 12 months, the live weight and body length of replacement boars were 268 kg and 175 cm, the thickness of the fat was 8,9 mm, the height of the longest back muscle was 51,5 mm, the content of lean meat in the body was 62,6 %, which corresponds to the class “elite”. Boars have been separated into reproductive traits. Improvement of lines is carried out through the continuators of related groups. Analysis of genetic studies of animals of new stud lines has shown that they have a high frequency of occurrence of desirable alleles by genes: RYR1 (stress-resistant animals) – 1,0; IGF-2 (fattening and meat traits) – 0,783; ESR (reproductive traits) – 0,608; MUC4 – (resistance to escherichiosis) – 0,786.

The results of studies of the fattening and meat qualities of young pigs of large white breed of foreign origin, some biochemical parameters of blood serum and the results of calculating their correlation relationships are presented, and the economic efficiency of the research results is calculated. It was found that the biochemical parameters of blood serum in animals of the experimental group correspond to the physiological norm of clinically healthy animals, and their coefficient of variation ranges from 7.71 to 33.67 %. According to the main indicators of fattening and meat qualities (the age of reaching live weight of 100 kg, days, the thickness of the fat at the level of 6– 7 thoracic vertebrae, mm, the length of the chilled carcass, cm) corresponds to the “elite” class, and an effective assessment method sows and boars-producers by genotype is the use of a comprehensive index of feeding and meat qualities (B. Tyler index). The maximum indicators “average daily gain in live weight for the period of control fattening, kg”, “the length of the chilled carcass, cm”, “the length of the bacon half of the chilled carcass, cm” and the minimum values “age to reach live weight of 100 kg, days” and “bacon thickness the level of 6–7 thoracic vertebrae, mm ”is characterized by animals in which the comprehensive index of feeding and meat qualities (B. Tyler index) ranges from 160.14 to 174.04 points. Reliable correlation was established between the following pairs of signs: fat thickness at the level of 6–7 thoracic vertebrae, mm × total protein content, g / l (r=+ 0.375, tr=2.14), length of chilled carcass, cm × concentration of total lipoproteins , mg% (r=–0.622, tr=4.20), length of chilled carcass, cm × urea content, mmol/l (r=–0.445, tr=4.20), length of bacon half of chilled carcass, cm × content total protein, g / l (r=–0.533, tr=3.33), fat thickness at the level of 6–7 thoracic vertebrae, mm × concentration of total lipoproteins, mg% (r=–0.652, tr=4.55) the average daily gain in live weight for the period of control feeding, kg × concentration of total lipoproteins, mg% (r=+0.492, tr=2.99). The above indicates the prospect of using some biochemical indicators of blood serum for early prediction of fattening and meat qualities. It was established that the maximum increase in production in terms of "average daily gain in live weight during the period of control fattening, g" (4.87 %) was obtained from animals in which the B. Tyler index ranged from 160.14 to 174.04 points.

Depending on the characteristics of mothers feeding, the results of assessing the morphological composition of blood and some hematological parameters, trace element composition of blood and the dynamics of the average daily gain in live weight of calves are considered. In the Atninsky municipal district of the Republic of Tatarstan in the agricultural production complex “Plemzavod named after Lenin ”conducted a research and production experiment on Holstein cows (30 heads), as well as on calves that were received from them. All laboratory studies were carried out in the department of agrobiological research of the Tatar Scientific Research Institute of Agricwlture, FRC KazSC RAS. It was revealed that the content of leukocytes on the 60th day in calves of group II was significantly (p <0.05) lower than in control animals by 41.31%. On the 90th day, the hemoglobin concentration in individuals of the control and III groups significantly increased by 27.05% (p <0.001) and 29.69% (p <0.01), respectively. On the 60th day, the concentration of cobalt in individuals of group III was significantly (p <0.01) higher than in animals of group II by 7.94%. A significant increase in zinc concentration on the 90th day was found in individuals of the experimental groups - by 30.04 (p <0.01) and 19.56% (p <0.001), respectively, and manganese - for calves in the control %, p <0.01). Evaluation of the average daily gain showed the presence of a trend of its superiority in individuals of group III over the rest by 17.96 and 7.44% compared with animals of groups I and II, respectively.

Numerous studies have shown that animals with the same genetic potential can differ in productiveness. In this regard, specialists in this industry, when predicting the milk productivity of adult animals in the process of raising young cattle, divide rearing into separate periods. In order to study the conditions for growing dairy calves, a comparative analysis of the conditions for keeping and feeding calves in two farms of the Republic of Tyva was carried out. The conditions of growing calves in the dairy period in the conditions of different farms with the same breed composition of cattle were studied. A comparative analysis of the influence of the composition and level of the diet on the growth of young animals is given. Calves of both groups by birth weight at birth did not have significant differences: they were 0.05-0.07 kg. In dairy farms MUP “KaaKhemsky” and “OOO Turanskoye” young cattle from birth to 6 months are kept in separate rooms. There are no significant differences in the calf feeding schedule. In the Municipal Unitary Enterprise “Kaa-Khemsky” feeding with haylage of young animals is introduced from two months of age; at the farm of “OOO Turanskoye” silage has been given to calves from 4 months. However, from 4 months to six months of age, they showed a significant difference in the increase in live weight. At 4 months, the difference averaged 4.27 kg, at 5 and 6 months – 6.39 and 8.59 kg, respectively. As a result of the studies, it was concluded that a decrease in the drinking of whole milk and the introduction of a substitute at its early, three-month-old age, which are compensated by a large intake of hay, feed and silage, do not provide a high average daily gain in live weight of the growing organism of young cattle.

The most perspective genotype in our region is Red White-belted breed, which has high performance both under pure breeding and under crossing with other breeds. The results of complex evaluation of Red White-belted swine of the herd bred in SE "RF Zoryane" breeding farm are presented. It was revealed that animals of the farm comply with elite class and the first class. The main breeding boars used at the farm belong to such genealogical lines: Deviz, Division, Dantist, Debut, and Dobryak. In the structure of the herd, the most numerous was Dobryak line, which part was 58.8%, Division, Debut, Devis lines – 11.8% per line, Dantist line – 5.8%. The herd sows belong to 7 families: Drabowka, Dekada, Dyktsiya, Doina, Dylema, Delta, Dogma. Average prolificacy of the sows was 10.0 piglets. Litter weight at 60 days’ age was 181.0 kg, and live weight of piglet – 19.0 kg. The performance of sows as prolificacy increased by 0.6 head on average. The complex appraisal index for the herd was 104.1 points. The average daily gain of the replacement pigs was 570 g. The highest daily gain was from five to six months – 611.2 g, and the figure of compactness index characterized a certain elongation of animals, increasing meat traits. Further work with Red White-belted breed aims at preserving and expanding the breeding base and genealogical structure, as well as increasing the reproductive, fattening and meat traits.

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.
