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.

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.

Goal. To accelerate the selection process and create populations of pigs with high level of productivity to assess the most effective modern methods breeding value of large white pigs in the SE "DG" Pasichna "Institute of Feed and Agriculture Podillya NAAS" Starosinyavsky district of Khmelnytsky region on the basis of a combined assessment of repair young for their own productivity and assessment meat qualities by MD Berezovsky and B. Tyler and the most promising method BLUP. Methods. Comparison, zootechnical and biometric analyzes. Results. The breeding value of pigs of large white breed of the breeding farm of SE "Pasichna" ICSGP NAAS "Starosinyavsky district of Khmelnytsky region by modern effective methods, namely: BLUP. According to the average indicators of the combined assessment of own productivity of animals at control fattening, taking into account their live weight on the date of birth and weaning, average daily gain, live weight and age of 100 kg, body length and fat thickness, boars significantly outweighed pigs. Compared with pigs, their live weight at the date of birth and weaning (at the age of 30 days) was higher by 0.1 and 0.81 kg. The age of reaching a live weight of 100 kg exceeded by 5.43 days, the average daily gain of 0.016 kg. Live weight and body length of pigs on the date of fat thickness measurement was greater by 4.04 kg and 1.03 cm. Lifetime fat thickness at three measurement points at the level of 6–7 thoracic vertebrae, on the buttocks and in the midpoint of the back between withers and buttocks was thinner by 0.92; 0.94 and 1.06 mm. Evaluation indices of fattening and meat qualities by growth energy and fat thickness (Ia) and average daily gain and fat thickness (Iv) in boars indicate their higher level by 2.07 and 7.67 points compared to pigs and are equal to, respectively, 95.12 ± 1.95 and 152.96 ± 2.38 points. The coefficient of variability (Cv, %) of indicators of own productivity and estimated indices of fattening and meat qualities of repair boars ranged from 1.92% (body length on the date of fat thickness measurement, cm) to 15.12% (age of live weight 100 kg, days), repair pigs – from 4.63% (body length on the date of fat thickness measurement, cm) to 28.19% (index of assessment for growth energy and fat thickness, (Ia), points). The best average values of indicators of breeding value of animals are found on the basis of modern, most promising method BLUP, because it is considered in terms of mathematics, statistics and selection is the most accurate, well-founded, has the best theoretical basis and the lowest error variance. The average value of the BLUP index (parent lines) for boars of large white breed is 101.71 ± 1.681, pigs – 96.94 ± 0.724 points. At the same time, boars outweighed pigs by 4.77 points. The most positive correlation between live weight of piglets at weaning with their body length (r = 0.16), average daily gain (r = 0.19) and fat thickness (r = 0.24), the average correlation between the indices of fattening and meat qualities according to MD Berezovsky and B. Tyler (r = 0.56) P > 0.99 and the weak correlation between live weight of piglets at weaning and the BLUR index (r = 0,21) P > 0.99. It should be noted that there are almost no correlations between the fattening and meat quality indices of pigs and the BLUP index. Conclusions. In the conditions of breeding and specialized farms for the production of commercial pork in the region, to determine the breeding value of animals for further reproduction of their own herd and sale to other breeding farms of Ukraine, to systematically assess repair young animals for their own productivity and clear qualities of pigs and the most perfect BLUP index.

High milk productivity of cows after calving is the cause of liver damage in the form of hepatosis and premature retirement of animals. In such cases, a pathological examination simultaneously reveals violations in the form of protein and fatty degenerations with the subsequent destruction of cells, as well as disturbed circulation in the liver. Also, hepatoses can cause such postpartum complications in cows as retention of placenta. For the prevention of hepatosis, the drug “Ovostim-ct” is proposed, which contains cytotoxic sera against the tissues of the liver, ovary, spleen and muscle. In order to prevent liver damage and postpartum retention of placenta, the drug is used 1-1.5 months before calving at a dose of 1 ml per 100 kg of live weight subcutaneously or intramuscularly. The use of the hepatoprotector allowed to reduce the number of cases of hepatosis and retention of placenta in cows after calving. Also, “Ovostim-ct” had a favorable effect on the biochemical parameters of the blood serum of cows: there was an increase in the concentration of total protein by 6.7%, albumin - by 15.6% and glucose - by 45.8% in the blood.

ABSTRACT The aim of this study was to evaluate the effect of sorghum silage substitution with different proportions of triticale silage on the performance and carcass of Braford heifers. Twenty-four Braford heifers were randomly assigned to four diets where sorghum silage was replaced at 0%, 30%, 60%, and 100% for triticale silage in a feedlot system. During sixty-tree days of the experiment, the feed intake, feed ratio conversion, and average daily gain were measured. The heifers were slaughtered and the effects of the sorghum and triticale silage in carcass characteristics were evaluated. The replacement of sorghum silage with triticale silage did not affect the feed intake and average daily gain (P> 0.05). Feed gain ratio was higher for the heifers that received lower proportions of triticale silage (0% and 30%) in replace sorghum silage (P <0.05). Eye loin area and fat thickness were similar among treatments (P<0.05). Other carcass characteristics, such as slaughter live weight, dressing percentage, conformation and fat classification were similar among experimental treatments (P<0.005). Triticale silage can replace sorghum silage for finishing beef heifers in feedlot system and provides similar carcass characteristics.

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 investigation was carried out in the “Rossiya” LLC in Mozhginsky district of Udmurt Republic. For research three groups of piglets of large white breed at the age of 30 days after weaning from sows were formed according to live weight at birth. The live weight of hogs at birth were determined by their weighing individually. The first group consists of the pigs whit an average live weight at birth 1.25 kg in the amount of 18 heads and the second and third – pigs whit an average live weight under birth 1.45 and 1.71 kg in the amount 14 and 11 heads, respectively. The animals were kept in the group pens. Their feeding was executed fodder of the own production. The conditions of the animals feed and kept in the groups were the same. The aim of the research was to study of a growth, development, and the feed qualities of the hogs in the dependence on theirs of a live weight at birth. The growth and development study of the hogs was carried out by weighing them in 30 days, in 3 months, in 5 months, in 7 months. The study of the feed qualities was carried out taking into account an average daily gain, the expenses of fodder on 1 kg gain and a thickness of the fat over thoracic vertebrae. The obtained experimental data were processed with use of a tabular editor Microsoft Excel – 2010. The reliability of the difference arithmetic means was determined with use of a Student’s -test. Studies have shown that the piglets of the II and III groups surpassed their peers in the I in live weight in 30 days. – by 1.22-2.64 kg, 3 months – 4.56-9.52 kg, 5 months – 11.36-15.17 kg, 7 months – 15.30-15.89 kg (P> 0.999). In terms of average daily gain, fodder costs and fat thickness, the boars of the II and III groups surpassed their peers in the I by: 51.81-91.31 g, 0.29-1.67 fodder. units and 5.78-11.56 mm (P> 0.999), respectively.

The article presents the results of studies of fattening and meat qualities of young pigs of different genealogical lines of large white breed and genotypes by the gene of melanocortin receptor – 4 (MC4R). The research was conducted in “Druzhba-Kaznacheyivka” LLC, the genetics laboratory of the Institute of Pig Breeding and APV NAAS and the animal husbandry laboratory of the State Institution Institute of Grain Crops NAAS. The work was performed according to the research program of NAAS №30 “Innovative technologies of breeding, industrial and organic production of pig products” (“Pig Breeding”). DNA-typing of the melanocortin-4 receptor gene (MC4R) was performed by Kim K., Larsen N., Short T. et al. (2000). Evaluation of young pigs for fattening and meat qualities was carried out taking into account the following quantitative characteristics: the average daily increase in live weight during the period of control fattening, g; age of live weight 100 kg, days; fat thickness at the level of 6–7 thoracic vertebrae, mm; the length of the cooled carcass cm; the length of the bacon half of the cooled half-carcass, cm. The length of the cooled carcass was measured with a measuring tape from the edge of the fusion of the pubic bones to the anterior surface of the first cervical vertebra; the length of the bacon half of the cooled half-carcass - from the anterior edge of the pubic bone to the middle of the anterior edge of the first rib (Berezovsky, Khatko, 2005). Conditions for feeding and keeping young pigs of the experimental groups were identical and complied with zootechnical standards. Economic efficiency of use of animals of various genotypes (МС4RАА, МС4RАG) and biometric processing of the received data (Lakin, 1990). calculated according to generally accepted methods. It is established that young pigs of large white breed of controlled population at the age of reaching live weight of 100 kg exceed the minimum requirements of the elite class by 6.73, fat thickness at the level of 6–7 thoracic vertebrae – 30.84, length of chilled carcass – 3.52 %. Significant difference between animals of different genotypes by melanocortin 4 receptor gene (МС4RАА, МС4RАG) was established by the average daily gain of live weight during the control period of fattening, the age of reaching live weight of 100 kg, fat thickness at the level of 6–7 thoracic vertebrae, length half of the cooled half-carcass and a complex index of fattening and meat qualities (B. Tyler's index). Young pigs of large white breed line Kotilo UA 8819347 outperformed peers line Azuro UA 8800557 on average daily live weight gain during the control period of fattening by 5.29%, the age of 100 kg live weight – 3.29 %, fat thickness at the level of 6–7 breasts vertebrae – 7.14 %. The longer length of chilled carcass (by 1.13 %) and the length of bacon half of chilled half carcass (by 2.68 %) were characterized by animals of Azuro UA 8800557. The correlation coefficient between fattening and meat qualities in young pigs of large white breed of the controlled herd varies ranging from –0.865 (tr = 22.26, P < 0.001) to +0.913 (tr = 35.43, P < 0.001). The maximum increase in additional products was obtained from young pigs of the МС4RАG genotype (+2.57 %) and the genealogical line Kotilo UA 8819347 (+4.86 %), and its cost is +694.26 – 1312.88 UAH/head. in accordance.
