For several decades, widespread industrial crossing different breeds of pigs. However, intensive importation foreign breeding of pig and use foreign technologies, a prerequisite for improving meat and slaughter quality of livestock. Success in solving this problem depends on identifying the best combinations of parental pairs with a comprehensive study of regularities succession and the descendants of preferred breeding traits are determined by genes and polymer characterized by a wide range of variability influenced by environmental conditions. In terms of industrial use of the most successful combinations of lines, genotypes, even a slight increase productivity, ensure, ultimately, significant economic effects. The aim of our study was to evaluate the general (GCA) and specific (SCA) combining ability fattening and meat quality of pigs and calves landed determine the best options for combinations of parental pairs when crossed. Studies were conducted in conditions of industrial technology at without belt dependent concentrations type of feeding and regulated microclimate on the basis of LLB "Mayak-Agro" Cherkassy region. Groups breeder was formed by unique origin, age, physiological condition, body weight. Assessment fattening, meat quality, physical and chemical properties of meat and fat conducted by conventional methods Polivoda AM and else. The morphological composition of carcasses studied by diking corps. The chemical composition and physical properties of meat were determined by conventional methods in condition of biotechnology laboratories Cherkassy National University. B. Khmelnitsky. In the first stage crossed sows of Ukrainian large white breed (UVB) with boars Landrace (LA) English selection, and received from them hybrids (hybrids F1) sires with specialized meat breeds: Pietrain (P) British breeding red white girdle (RWG) and Duroc Ukrainian selection “Steppes” (DUSS). It is established that the use of these industrial crossbreeding schemes leading to improved slaughter yield of 4.4 - 8.4% in the carcasses of local groups. Severity of heterosis for slaughter relies was in the range of 0.16 to 1.88%. Combining breeds LA and UVB has increased the length of the carcasses in hybrids by 2.5 cm (P> 0.95) at the lowest standard deviation - 0.14 cm. At the same time, crossing two-hybrids local pig breeds of boars’ P led rather to reduce the carcasses length compared to the original parental forms 2.6 cm (P> 0.95). Regarding mass index posterior third corps tends to increase it to 11.3 - 12.5 kg accurate advantage of using Landrace breeds (P> 0.95) and pietrain (P> 0.999). The fact that the carcasses obtained from pigs combination 1/4UVB x 1/4LA x 1/2P, were significantly shorter and had the largest area "muscle eye" is quite natural and due to the influence of breeds belonging boars. The efficacy of the combination of maternal two-breeds form hybrids with UVB × LA boars pietrain and red white girdle, confirmed the calculated values of general and specific combining ability. When using boars breed red white girdle highest positive effect of general combining ability was observed in terms of area "muscle eye" (4.94) meeting of body (0.93) slaughter yield (0.35). In addition, the use of the scheme for industrial crossing red white girdle helped reduce fat content in carcass and thick bacon (- 1.41 - 0.64). Increasing the length of the carcass at slaughter hogs promoted the use of Duroc Ukrainian selection “Steppes” (1.32) and Landrace (1.08). Boars used breeds influenced fattening and greasy meat quality of offspring with different force. Its value depended on the individual animal and breeds consolidation for the identified - from negative 8.49 to positive 6.71% age achieve live weight of 100 kg and from minus 9.34 to positive 6.34% in the average daily increments. Differential power of selective effects on offspring among individual species ranged from (- 9.34) to (+6,71)% (P> 0,999). Given the importance of meat quality indicators as signs core products finals pig should always check the structural elements of Ukrainian large white breed on the matching ability. This lets use the best combination to improve performance and avoid unwanted flocks crossbreeds combinations.

The research was conducted on pig carcasses and meat of 12 pigs breed big Yorkshire fattened to approximately 125 kg body mass (group A), and 12 pigs of the same breed fattened to approximately 108 kg body mass (group B). Pigs were kept in the semi-outdoor system, with the same housing and feeding conditions. Meat quality was determined on the sample from M. longissimus dorsi, taken between the 13th and 14th rib. Body mass of pigs prior to slaughter 125..22 kg. and 108. 52 kg.) significantly influenced the quality of pigs breed big Yorkshire carcasses , but not the quality of the meat. Pigs with higher body mass (125.22 kg) had carcasses of different conformation (significantly higher relative share of yawl and abdominal rib -part and a lower relative share of less worth parts and shoulder) and composition (a lower relative share of meat on shoulder and a higher relative share of meat on abdominal-rib part) in relation to pigs with lower body mass (108.52 kg). The meat contents in carcasses was almost equal (47.04 % and 47.20%) in both analyzed groups of pigs. In terms of meat quality, that was usual, no significant differences (p>0.05) were determined between the analyzed groups of pigs.

Leptin receptor is one of the components of the system of regulating energy homeostasis of the organism. Leptin receptor gene (LEPR) polymorphism is associated with pig carcass index of the content of intramus- cular fat in its valuable parts, which is particularly important when assessing the quality of their carcasses for processing. Intramuscular fat is associated with meat fl avor characteristics and partly determines its tenderness, juiciness, and other parameters. Aim. To analyze LEPR gene (SNP NM001024587.1, p. 1987 C > T) polymor- phism in populations of various pig breeds and to establish its relationship with the quality of both meat and fat of pigs of Large White breed of Ukrainian breeding. Methods. Genetic-population analysis of nine pig breeds, associative analysis on the search connection of LEPR gene polymorphism with quality of both meat and fat of pigs of Large White breed of Ukrainian breeding. LEPR locus genotyping was performed by High Resolution Melting (HRM). Results. All the studied breeds are characterized by polymorphism of the leptin receptor gene (SNP NM001024587.1, p. 1987 C > T), signifi cant breed specifi city in the distribution of frequencies of alleles was established. Statistically confi rmed effect (p < 0.05) of genotypes LEPR on the content of intramuscular fat, total dry matter and moisture in the meat, as well as the moisture content in the back fat of pigs of Ukrainian Large White breed was revealed. Higher content of intramuscular fat was found in the animals with genotype TT, while a smaller amount of intramuscular fat and more moisture in fat was revealed in heterozygotes. Conclusions. Genetic marker LEPR SNP NM001024587.1, p. 1987 C > T can be used in the marker-assisted selection to predict and improve the performance quality of the meat of pigs of Large White breed of the Ukrainian breeding. These results suggest that porcine leptin receptor gene controls the quality of fat comp- lex – inside muscles and in the dorsal part of the carcass.

The results of studies of the reproductive ability of sows of different genotypes are given taking into account the polymorphism g.1426G> A of the MC4R gene, the factor of repeatability of characters is determined, and the economic efficiency of the research results is calculated. The experimental part of the research was carried out in the conditions of the «Druzhba-Kaznacheevka» LTD in Dnipropetrovsk region. The objects of research were sows of the Large White breed. It was determined that sows of the main herd, according to signs of reproductive ability, belong to class I and class elite. The experiment showed that sows of genotype AG exceeded their peers of others (GG and AA) in terms of “born piglets total, heads” by 1.6 and 0.7 heads, “Live piglets born (multiple births), heads - by 1 6 and 0.9 heads, “the mass of the litter at the time of birth, kg” - by 2.7 - 1.3 kg., “the mass of the litter at the time of weaning at the age of 28-35 days, kg” - by 5, 1 - 3.9 kg. The difference between animals of the indicated genotypes is: for large-foetus - 0.06-0.01 kg, the index "evenness of the sow’s litter in live weight of piglets at birth, points" - 1.05-1.84 points, index of N. D. Berezovsky - 3.75 -2.36 points. The index of the safety of piglets before weaning ranged from 84.4 to 93.0 %. It was proved that the minimum value of the index “evenness of the sow’s littar in live weight of piglets at the time of birth, points (7.76 ± 1,082 points) are characterized by sows of genotype AA, in which the rate of multiple pregnancy ranged from 8 to 14 pigs, and the value of the sign“ large-foetus, kg "equaled 1.37 kg. The repeatability coefficient for sows of the main herd and sows of the Large White breed of different genotypes for the melanocortin 4 (MC4R) receptor gene ranges from -0.916 ± 0.1418 (І-IV farrow, genotype - GG, sign - “piglet safety before weaning, %) to 0.978 ± 0.0738 (I-V farrow, genotype - GG, sign - “large foetus”, kg ”). The maximum value of the phenotypic consolidation coefficient was found in sows of genotype AA according to the following quantitative characteristics: “live piglets (multiple births), heads.”, “litter weight at the time of birth, kg”, “litter weight at weaning age of 28-35 days, kg "," the safety of piglets before weaning ,% ". The sows of the genotype GG belong to the unconsolidated group according to the signs of reproductive qualities. The use of sows of the genotype for the melanocortin 4 (MC4R) AG receptor gene provides additional products at the level of 5.15 %, and its cost is 165.41 UAH /head.

Studies were carried out on the main indicators of the chemical composition and physical properties of muskulus longissimus dorsi of pigs of different genotypes during hybridization. The indicators of the chemical composition and physical properties of muskulus longissimus dorsi were determined by conventional methods. The materials of experimental studies were processed using methods of variation statistics. According to the amount of moisture, no significant difference between the control and experimental groups was established. According to the amount of protein in meat, a tendency to a slight decrease, compared with the control group by 1.4 (group III) … 1.9 % (group II) was established. The use of boars of Poltava meat breed led to a decrease in intramuscular fat in descendants by 0.25 % compared with peers of a large white breed (P <0.95), and precocious meat - to a real increase of this indicator by 0.43 % at P> 0 , 95. A tendency towards an increase in the amount of tryptophan (by 0.04 ... 0.05) and oxyproline (by 0.004 ... 0.005) in the muscles of hybrid animals was revealed in comparison with peers of pure breed of large white breed. In terms of the biological usefulness of meat proteins, animals of group III were the best - in terms of the quality of the protein of the longest muscle of the back, their advantage over peers of group II was 0.07, and compared with purebred peers. Group I - 0.12 (p <0.95). It was found that with the same area of the meat spot both in purebred large white breeds of animals and hydrides of different genotypes, there is a tendency to increase the latter compared to the control in a humid place: with a «share» of «blood» ½ pm by 2.2 %, and with a «share» of blood ½ cm - 1.4 %. A tendency has been established to increase the pH value of the longest back muscle in animals with a «share» of blood of specialized meat breeds compared with a large white breed. In hybrid animals with a «share» of blood of Poltava meat and precocious meat breeds, there is a tendency to increase the pH value in comparison with the large white breed by 0.15 (2.8 %) and by 0.17 (3.1 %), i.e. the meat of hybrid pigs, the pH of which has a shift towards alkalinity due to less accumulation of lactic acid, has a worse preservation.

Improving of fertility indicators and reproductive qualities of sows during artificial insemination in farms of different specializations is very topical issue. The introduction of artificial insemination of sows on breeding farms by the spermdoses of optimum volume, by the frozen-thawed and sex sperm requires the introduction of innovative reproductive technologies. The use of economical methods of artificial insemination of sows using a minimum number of sperm in a small volume of spermdose in order to achieve high rates of fertility and prolificacy was proven in numerous experiments of the authors. Significantly reduced spermdose may be sufficient if the sperm enters deep enough into the uterus. Vitality of sperm does not depend on the size of spermdose, but the best place for sperm to survive one oviducts where they keep the fertilizing capacity from 9 to 27 hours. So deep intrauterine insemination of sows improves conditions for sperm survival The aim was to study the feasibility and justification for widespread implementation in to production on breeding farms of intrauterine insemination of sows morder to increase their fertilization and prolificacy and  to save the boar sperm with the highest index of breeding values. Experiments were conducted in terms of selection and genetic center of Agrofirm "Mig-Service-Agro" in Mykolaiv region. In the experiment used 65 sows of live weight of 280-320 kg wiht 2-4 farrowing were. Sows in sexual hunting were showed once daily in the morning using a boar-prober. Artificial insemination was performed twice: the first time - in the afternoon and at 14-16 p.m. The second time – in the morning of the next day at 9-10 am. For artificial insemination of sows were ed using experimental spermodes with volume of 40 ml which contained 1.5 billion of a Active sperm. For the dilution of sperm was used Durasperm - KRUUSE (Denmark) the period of sperm perpetuation is 5-7 days. To enter the were semen used catheters Magaplus S, (Spain) for intrauterine insemination of sows. Analysis shows that the period from weaning to insemination has significant difference comparing sows of large White breed with Landrace breed (p <0.001), with genotype sows F1 (p <0.01) and sows of the Duroc breed (p <0.05). For all selected 65 sows duration of suckling period, was estimated which averaged 32.2 days and the average time from weaning of pigs to their sexual inclination and the first intrauterine insemination 6.8 days that meets the physiological norm. After intrauterine insemination of sows of then 48 farrowed, which wich made for 73.9%. іncluding live 5 emergency farrow  were obtained, representing 10.4% of all amount. Percentage of farrow is considered physiologically normal – 80%, or more of total insemined sows. The very low percentage of farrow 53.3% had of sows F1, and the highest percentage was found by sows of the Duroc breed – 85.7%. Pregnency of sows were received just 17, which made 26.1% and highest percentage – 46.7% was set by sows F1. Analysis of the pregnancy sows shows that on average it is 116.2 days was the longest – 117.1 days was set in Landrace breed sows and the short est 115.5 days in Large White breed, but the difference is not significant. 571 pigs were received, іncluding live 451 head, which is 78.9%. The largest percentage of іncluding live piglets obtained from sows F1 – 82.5%, and the lowest in Landrace breeds – 77.0% and Large White – 77.3%. Exit of all piglets per sow without emergency farrowings is 12.2, іncluding live – 9,8. The highest yield were obtained piglets from sows F1 – 13.1, іncluding live – 10.9, the lowest yield of sows of the Duroc breed – 10.6, іncluding live 9.1, which has significant difference compared with the control (IDPs) and other breeds.  After intrauterine insemination 8 sows showed cyclic deregulation in 20-25 days, ie repeated sexual hunt took place on average 22.3 days. These sows were inseminated by not fractional way, they farrowed and an average litter just 13.1 piglets per sow, іncluding live - 11.3 was obtained. Repeating after intrauterine insemination on 45-48-49 day in the sexual hunt came about three sows for artificial insemination by not fractional method 3 farrowed and was obtained output – 13.3 piglets, іncluding live – 11.7. It should be noted that the best sow Large White breed №12 after intrauterine insemination bore 16 pigs, іncluding live 11, sow of Landrace breed №1556 – 18 pigs, іncluding live 12, Duroc №5888 – 13 pigs, іncluding live 11, sow F1 №167 – 20 pigs, іncluding live 14 pigs. Breeding requires more careful handling with major sows taking into account their breeding value and cost, that’s why we believe that there is no need to risk causing injury genitals with intrauterine insemination if a sufficient number of spermdoses of boars-sires exist.

SUMMARYA total of 156 pigs of the Large White breed were used in a series of four experiments to test the suitability of barley which had been stored with a high moisture content as an ingredient in the diets of growing pigs. Barleys with mean moisture contents of 26·3%, 28·1% and 21·2% and a range from 19·6% to 30·5%, from three successive harvests were used.In all the trials there was evidence that the use of moist barley in diets for growing pigs had an adverse effect on live-weight gain and feed conversion ratio, the effect being independent of whether feed intakes were equated on the basis of the dry-matter content of the diets. In one of the experiments performance was depressed to the extent of causing changes in carcass characteristics. The performance of pigs given rolled barley was similar to that of others given ground barley.

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.
