    Assessment of quality of pig carcasses in Ukraine according to national and European classification
    (Wageningen Academic Publishers, 2014) Kravchenko, O. I.; Loza, Arthur; Getya, A. A.; Кравченко, Оксана Іванівна; Гетя, Андрій Анатолійович
    The existing Ukrainian system of classification of pork carcasses was established in the Soviet Union. At slaughterhouses conducted a visual assessment of the degree of muscles development, measure of carcass weight and back fat thickness (6-7 thoracic vertebrae), but sex of an animal is not considered as well as lean meat percentage. At the slaughterhouse ‘Yubileinyi’, Dnipropetrovsk region of Ukraine, 160 hybrid pigs were slaughtered (Landrace x Yorkshire x Peitrain, Yorkshire x Landrace x Duroc) and evaluated according to both Ukrainian and European classification. For EUROP assessment the French device CGM was used which involves measuring between.last 3 and 4 thoracic vertebrae. According to Ukrainian classification all 160 carcasses were rated as the second category. The second category includes carcasses with weight from 47 to 102 kg and the thickness of fat from 10 to 30 mm at the level of 6-7 thoracic vertebrae. Test assessment of carcasses according to European system has the following classification: 39 heads - class S, 88 heads - class E, 28 heads - class U and 5 heads - class R. It was determined that the biggest part of slaughtered pigs were castrated; 116 heads, or 72.5%. Slaughtered female have the highest MLD thickness (63.2±0.33 mm) and lean meat percentage (60.52±0.38%) at the same time have the thinner back fat (14,9±0,13 mm). In whole animal group lean meat percentage was 58.14±0.26%. Nowadays in Ukraine conducted work from the adaptation and implementation of the assessment system and payment of carcasses at slaughterhouses based on lean meat percentage of the carcasses.

    Perspectives of use of totai meat percentage as a selection criterion in pig industry of Ukraine
    (Wageningen Academic Publishers, 2015) Kravchenko, O. I.; Getya, A. A.; Кравченко, Оксана Іванівна; Гетя, Андрій Анатолійович
    The demand for lean pork is being increased in Ukraine for recent years. This tendency is taken into consideration by the pig industry which improves housing- and feeding technology. At the same time specialized genotypes, including imported animals from different countries, became more and more popular. Over the last 10 years the average daily gain in Ukrainian pig farms increased by 1.96 times. But due to an outdated payment system for the animals delivered to slaughterhouses one of the main criteria for the carcass quality assessment, namely ‘total meat percentage’ (TMP), is not evaluated. To analyse the carcass quality based on TMP and to prove the need of involvement of this trait into Ukrainian breeding programs 7,246 pigs from 12 farms in central Ukraine were slaughtered. The measurements o f TMP were done using CGM-device. The average weight of carcasses of gilts and castratcs was 88.38 kg and 89.03 kg respectively. The TMP o f carcasses o f gilts was 59.30% and o f castrates 57.60%. Despite the fact that according to Ukrainian classification system all carcasses were related to the 2nd class, a considerable variation o f total meat percentage was established. So, the average value of this trait in the worst 30% carcasses o f gilts and castrates was 50.00±1.22% and 48.50± 1.19% respectively while in best 30% - 64.50±0.76% and 64.00±0.91%. The difference between 30% best and 30% worst carcasses o f gilts and castrates was 14.5% and'l 5.5% respectively (P<0.001). Understanding the importance of trait TMP for efficiency of pig industry the implementation o f European payment system is needed as well as integration of this trait into breeding programs o f Ukrainian genetic companies.

    Quality of pig carcasses of surgical- and immunocastrated males slaughtered at different live weight
    (Wageningen Academic Publishers, 2018) Povod, M.; Kravchenko, O. I.; Getya, A. A.; Kodak, O.; Кравченко, Оксана Іванівна; Гетя, Андрій Анатолійович
    effectiveness of fattening. Traditionally Ukrainian pork producers slaughter the animals with live weight 100-110 kg but would like to raise the weight before slaughter, working with hybrid pigs. According to reports of some researchers the increasing of weight before slaughter causes worsening of carcass quality, especially in surgically castrated and entire males. As a solution the immunological castration can be taken into account especially for rising heavy weight pigs. This assumption has been investigated in presented research. The trial has been organized under the condition of commercial farm on hybrid animals (Yorkshire* LangrassxMaxgro). Two groups of pigs with 30 heads in each were formed (surgical and immunological castrated males). Surgical castration was done at the age 4 of days, immunological - by application of Improvac vaccine in accordance to the instructions for use. All animals were kept together and slaughtered at the same time but with different weights: from 100 till 120 kg. Carcass evaluation was made using Fat-o-Meater S71. The thickness of the backfat was measured at the level of 6-7 thoracic vertebra, and at sacrum. Carcass grading has been done using EUROP and Ukrainian scale. Sensory evaluation of carcasses after slaughter was performed. The results suggest that increasing of live weight before slaughter of immunocastrated males till 120 kg does not influence negative their carcass quality. Dressing percentage of carcasses did not depend on live weight before slaughter in both groups. Carcasses of immunocastrated males had lower backfat thickness measured at 6-7 thoracic vertebra: slaughter at 100 kg - by 2.8 mm; slaughtered at 120 kg - by 3.3 mm. After slaughter at weight 120 kg 70% of carcasses of immunocastrated males were graded E + U, while in the group of surgical castrated males such carcasses were only 50%. It was not detected critical level of boar odour in all slaughter weights.

    The decreasing role of native genetic resources in modern Ukrainian pig production
    (Wageningen Academic Publishers, 2013) Kravchenko, O. I.; Getya, A. A.; Kodak, O.; Кравченко, Оксана Іванівна; Гетя, Андрій Анатолійович
    Conservation o f animal genetic recourses is a global issue and the reported rate of breed extinctions is of great concerns. In the livestock sector o f Ukraine genetic erosion concerns mostly local, native breeds which are replaced by a narrow range of high-yielding exotic breeds considered to have a competitive advantage in more intensive production systems. There is a big threat that Ukraine loses its national genetic recourses being replaced by breeds not well adapted to local climatic, environmental and technological conditions. Currently there are 6 native pig breeds in Ukraine: Mirgorodska (M), the Ukrainian white steppe (UWS), the Ukrainian spotted steppe (USS), Poltava meat (PM), Ukrainian meat (UM) and the Red white belt (RWBB). An analysis o f occurrence and geographical distribution o f Ukrainian pig breeds revealed for the years 2006-2012 a massive reduction in the number of breeding farms keeping those native breeds, namely: M: by 62.5%; UWS: by 72.7%; PM: by 68.4%; UM: at 43.5%; RWBB: by 41.2%. Most critical is the number of sows: Mirgorodska: 383 heads; Ukrainian white steppe: 334 heads; Poltava meat: 469 heads; and Ukrainian spotted steppe: 26 heads. Therefore the most urgent problem o f Ukraine, is the development and implementation of strategies to maintain its autochthonous animal breeds, but a conservation program cannot be established without reliable characterization and monitoring o f breeds. Breed certification, establishing definitions for what to be considered as pure bred, detection and timely elimination o f crossbred animals, are currently considered to be the most urgent tasks.

    Застосування імунокастрації для покращання якості туш кнурів в умовах промислового виробництва свинини в Україні
    (Вісник аграрної науки Причорномор’я. https://visnyk.mnau.edu.ua, 2017) Кравченко, Оксана Іванівна; Kravchenko, O. I.; Гетя, Андрій Анатолійович; Getya, A. A.; Повод, Микола; Povod, M.
    У роботі представлено порівняльний аналіз якості туш, отриманих від імунокастрованих та хірургічно кастрованих кнурів. Встановлено, що туші імунокастрованх кнурів мали меншу товщину шпику по всій туші, вищий вміст м’язової тканини, а також переважали хірургічно кастрованих за вмістом великокускових напівфабрикатів (ошийок, корейка, м’ясо окосту). In this article the results of comparative analyze of carcass quality of immunocastrated versus surgically castrated boars are shown. It has been determined that the carcasses, obtained from immunocastrated boars, had lower backfat level over the whole carcass and higher meat content. They also had higher content of semi-fi nished products like neck, loin, ham. В данной статье представлены результаты сравнительного анализа качества туш, полученных от иммунокастрированных и хирургически кастрированных хряков. Установлено, что туши иммунокастрированных хряков имели меньшую толщину шпика по всей туше, болеем высокое содержание мышечной ткани, а также превосходили хирургически кастрированных по содержанию крупнокусковых полуфабрикатов (ошеек, корейка, мясо окорока).

    (Сумський національний аграрний університет, 2017) Повод, Микола; Кравченко, Оксана Іванівна; Гетя, Андрій Анатолійович; Самохіна, Євгенія; Шпетний, Микола; Povod, N.G.; Kravchenko, O. I.; Getya, A. A.; Samokhina, E.A.; Shpetniy, N.B.
    В наведеній статті проведено порівняльний аналіз інтенсивності росту, оплати корму та збереження не кастрованих та хірургічно кастрованих поросят поєднання йорк- шир×ландрас×максгро в умовах ТОВ «НВП «Глобинський свинокомплекс». Результати проведених досліджень свідчать, що некастровані поросята в період їх дорощування до 77-добового віку мали вищий рівень середньодобових та абсолютних приростів живої маси на 7,4% та 3,4% відповідно (Р<0,05). Відповідно і загальна маса всіх поросят та маса однієї голови по завершенню дорощування у них були вищою, на 2,1% і 5,76% (Р<0,01). Разом з тим, не кастровані поросята поступались хіру- ргічно кастрованим аналогам за збереженістю на 4,5%. In this article is listed, a comparative analysis of the intensity of growth, the payment of feed and the safety of non-neutered and surgically castrated piglets, a combination of yorkshire×landras×maksgro in the conditions of LLC "NPP" Globinsky svinokompleks ". The results of the conducted studies show that non-castrated pigs during their growing up to 77-dayold age had a higher level of daily average and absolute growth of live weight by 7,4 % and 3,4% respectively (P <0,05). Accordingly, the total weight of all piglets and the weight of one head after the completion of growth in them were higher by 2,1 % and 5,76 % (P <0,01). At the same time, non-castrated piglets were less than surgically castrated analogues for preservation by 4,5 %.
