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. Найбільш відчутне зниження у потомків тов-щини шпику на рівні 6–7-го грудних хребців та підви-щення маси задньої третини півтуші забезпечитьвикористання на заключному етапі трьохпородногосхрещування кнурів породи п’єтрен англійського по-ходження. 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 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 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 indicators of growth and development, fattening and meat qualities of pigs of the breeding center “Lozovoe” CJSC “Plemzavod-Yubileyny” of the Tyumen region were evaluated. The indicators that characterize the growth and development of young animals were taken into account: live weight, age, average daily growth. When the live weight of 100 kg was reached, an ultrasound device was used to evaluate the thickness of bacon, the depth of muscles and the yield of lean meat, which are in the database of breeding records for 2011-2020. To characterize the meat qualities, 1144 Landrace piglets were slaughtered, 275 - large white breed, 129 - Pietren breed, 339 hybrids (LxKB), 159 hybrids (LxD), 460 hybrids obtained from boars of foreign selection. A comparative analysis of commercial hybrids of various variants of crossing pigs of domestic and foreign selection is carried out. Processing of the research results was carried out in the laboratory of Molecular diagnostics and Biotechnology of the Don State Agrarian University. The influence of the breed is established.
