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.

The study presents the results of research on fattening and meat qualities of store pigs of large white breed of different intra-breeding differentiation by the gene of melanocortin-4 receptor (MC4R). The study calculated the economic efficiency of animals of different genotypes. The following fattening and meat qualities were evaluated: 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; length of bacon half of chilled half-carcass, cm. It was established that store pigs of controlled population at the age of reaching live weight of 100 kg, fat thickness at the level of 6-7 thoracic vertebrae, and length of chilled carcass exceed the minimum requirements of the elite class by 13.69%. A significant difference between animals of different genotypes by the gene of the melanocortin-4 receptor (MC4RAA, MC4RAG) was established according to the average daily live weight gain during the control fattening period (4.24%, P <0.01), the age of reaching a live weight of 100 kg (2.18%, P <0,01), fat thickness at the level of 6–7 thoracic vertebrae (8,45%, P <0,05), length of chilled carcass (2,26%, P <0,001), length of bacon half of chilled half carcass (3.36%, P <0.001) and selection index (SI) (18.92%, P <0.05). Significant correlations in animals of different genotypes by the melanocortin-4 receptor gene (MC4RAA, MC4RAG) were identified regarding the following features: average daily live weight gain during the control period of fattening × age of 100 kg live weight (-0.475 – -0.853), average daily live weight for the period of control fattening × SI (+0.686 - +0.770), SI × age of reaching live weight 100 kg (+0.515 – -0.721), SI × fat thickness at the level of 6-7 thoracic vertebrae (-0.944 – -0.885), length of chilled carcass × length of bacon half of chilled carcass (+0.899 – +0.861). The maximum increase in additional products was obtained from the sale of young pigs by the gene for the melanocortin-4 receptor MC4RAG – +2.02%.

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 results of studies of fattening and meat qualities of young pigs of different origin and intensity of formation in early ontogenesis are presented.  The economic efficiency of the results of the studies is calculated. The study was conducted under the conditions of pedigree reproducer for breeding pigs of the large white breed of LTD “Druzhba-Kaznacheevka” of Dnipropetrovsk region. The object of study was young pigs of English and Hungarian origin, as well animals of varying intensity of formation in early ontogenesis. Estimation of young pigs by absolute and integrated indicators of fattening and meat qualities was carried out taking into account the following quantitative characteristics: average daily weight gain for the period of control fattening, kg, age of reaching live weight of 100 kg, days, thickness of the lard at the level of 6–7 thorax , mm, length of cooled carcass, cm, length of bacon half carcass, cm, index “intensity of formation” (∆t), selection index (SI) and “T-factor”. The economic efficiency of the results of the research was calculated according to the indicator "average daily increase of live weight during the period of control fattening, kg". The analysis of the results of the research shows that the young pigs of the large white breed of the control herd by the age of reaching the live weight of 100 kg were outweighed by the minimum requirements of the Instruction for pig testing by 9.78%, by the thickness of the lard at the level of 6–7 thoracic vertebrae – by 30.33% and by length of the cooled carcass – by 3.52%. Taking into account the class of origin and index “intensity of formation, points” (∆t), the difference between the groups by age of reaching live weight of 100 kg, the thickness of the pelvis at the level of 6–7 thoracic vertebrae and the length of the cooled carcass ranges from 2.24 to 8.03%. It was found that in terms of the main indicators of fattening and meat quality, the young pigs of the large white breed of Hungarian breeding are more consolidated (К1 = 0.085–0.344, К2 = 0.086–0.338). The maximum increment of additional production (average daily weight gain during the control fattening period, kg) was obtained from young pigs of large white breed of English origin (2.39%) and animals with index ∆t at the level of 0.619–0.748 points (1.38%). To evaluate the animals of the main herd (brood boars, sows) according to the fattening and meat characteristics of their offspring, we suggest the use of SI and T-factor breeding indices.

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.

У статті викладені результати оцінювання сви-ней іноземного походження та кровності за відгоді-вельними й м’ясними ознаками з визначенням кращихпоєднань батьківських генотипів для одержанняефекту гетерозису у потомків. Дослідженнями вста-новлено, що найвищу інтенсивність росту під часвідгодівлі мав гібридний молодняк, одержаний у разісхрещування двохпородних свиноматок (велика білафранцузького походження х дюрок німецького поход-ження) з кнурами породи п’єтрен англійського поход-ження.

Чистопородне розведення свиней великоїбілої породи не сприяє підвищенню відгодівельних ім’ясних ознак у молодняка, навіть за об’єднання в їхгенотипі спадковості тварин французького, німецько-го й англійського походження. Прибутковість відго-дівлі молодняка свиней в умовах сучасного промисло-вого виробництва повинно ґрунтуватися на поєдну-ваності порід, особливо, коли використовуютьсятварини іноземного походження. The article presents the results of the evaluation of pigs of foreign origin and crownest of  fattening and meat traits with determining of the best combinations of parental genotypes to obtain the effect of heterosis in the descendants. Research has shown that a hybrid  young stock had the highest growth rate during feeding, who was obtained by crossing dohorty sows (large white of French origin x Duroc of German origin) with grunts of Pietrain breed of English origin. The largest declines of the young stock’s backfat thickness at 6-7 thoracic vertebrae and increase the mass of the posterior third of the side will ensure three times Pietrain boars’ cross breeding of English origin at the final stage. Purebred breeding of pigs of large white breed does not promote the fattening and meat traits in young stock, even for the unification of their genotype heredity animals of French, German and English origin. The profitability of fattening of young pigs in the conditions of modern industrial production should be based on associations of species, particularly when animals of foreign origin are used.

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.
