I.; Getya, A. A.; Кравченко, Оксана Іванівна; Гетя, Андрій АнатолійовичIn modern pig production systems, the choice of optimal live weight of animal before slaughter belongs to the important issues. To clarify this question 80 heads of final hybrids YorkshirexLandrace>Документ 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 АнатолійовичThe 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.Публікація Association of PIT1 gene polymorphism with milk productivity and body conformation traits in dairy cattle("Regulatory Mechanisms in Biosystems", 2025-11-10) Vashchenko, P. A.; Slynko, V. H.; Shaferivskyi, B. S.; Myronenko, O. I.; Ващенко, Павло Анатолійович; Слинько, Віктор Григорович; Шаферівський, Богдан Сергійович; Мироненко, Олена ІванівнаMarker-assisted selection (MAS) is an effective approach to accelerating genetic progress in livestock by identifying polymorphisms associated with economically important traits. The pituitary-specific transcription factor gene PIT1 plays a regulatory role in the synthesis of growth hormone and prolactin, thus potentially influencing milk yield and body conformation in dairy cattle. This study aimed to investigate the distribution of PIT1 genotypes and their associations with productive and morphometric traits in Ukrainian Red-and-White dairy cows – a local breed with limited genetic characterization. Genotyping was performed using PCR-RFLP with restriction enzyme HinfI on DNA samples obtained from 51 cows. Three genotypes (AA, AB, BB) were identified with frequencies of 0.059, 0.549, and 0.392, respectively. The population was in Hardy–Weinberg equilibrium, and the Polymorphic Information Content (PIC) value (0.34) confirmed an adequate level of variability for association analysis. The frequency of allele B was twice that of allele A, suggesting moderate genetic consolidation of the herd. Cows with the PIT1 BB genotype showed a significantly higher milk yield per lactation (higher by 14.8%) and a 9.8% higher 305 day yield compared with the AB group. In contrast, genotype AB was associated with greater chest width (by 3.4%), as well as higher pelvic–thoracic and thoracic indexes, indicating a more robust body type. No significant differences were found among genotypes for milk fat content, udder morphology, milking speed, live weight, or service period duration.The obtained results demonstrate that PIT1 polymorphism affects milk yield and certain conformation indexes in Ukrainian Red-and-White cattle, primarily through mechanisms related to endocrine regulation rather than skeletal development. The presence of both alleles at moderate frequencies highlights the genetic diversity of this local breed and supports its potential use in further genomic selection programs aimed at improving milk productivity while maintaining adaptive traits.Документ Covid-19 pandemic effects on food safety - Multi-country survey study(2021) Kodak, T.; Djekic, I.; Nikolić, A.; Uzunović, M.; Marijke, A.; Liu, A.; Han, J.; Brnčić, M.; Knežević, N.; Papademas, P.; Lemoniati, K.; Witte, F.; Terjung, N.; Papageorgiou, M.; Zinoviadou, K.G.; Dalle Zotte, A.; Pellattiero, E.; Sołowiej, B.G.; Guiné, R.P.F.; Correia, P.; Sirbu, A.; Vasilescu, L.; Semenova, A.A.; Kuznetsova, O.A.; Vrabič Brodnjak, U.; Pateiro, M.; Lorenzo, J.M.; Getya, A.

M.; Шостя, Анатолій Михайлович; Usenko, S. O.; Усенко, Світлана Олексіївна; Rachynska, Z.; Viaskov, V.; Kostenko, I.; Glavatchuk, V.; Zygin, S.; Hmelnitska, Y.; Хмельницька, Євгенія ВікторівнаThe object of the study is the process of chemical transesterification of sunflower oil with increased mass fraction of moisture and acid value.Transesterification technology allows obtaining fats with the necessary physico-chemical properties without changing the fatty acid composition. The problem of using alkaline catalysts is rapid deactivation under the influence of impurities present in the fatty raw material. The greatest influence is exerted by moisture and fatty acids. Transesterification of sunflower oil with increased mass fraction of moisture and acid value in the presence of potassium glyceroxide, which is more resistant to deactivating impurities, was studied. Oil parameters: peroxide value 0.18 ½ O mmol/kg, acid value 0.08 mg KOH/g, mass fraction of moisture 0.05%, crystallization temperature –18.38°C.Oil samples with mass fractions of moisture from 0.1 to 0.75% (obtained by adding water) were stored for two months under the following conditions: temperature (20±2) °C, air humidity not more than 70%. After storage, the acid value was measured in each sample and transesterification was performed. The efficiency of the process was assessed by the oil crystallization temperature. The maximum values of oil indicators at which the potassium glyceroxide catalyst is effective were established: mass fraction of moisture 0.4%, acid value 0.28 mg KOH/g. At the same time, the crystallization temperature of sunflower oil is –3.95°C, which corresponds to the maximum increase in the crystallization temperature of oil as a result of transesterification. The results obtained make it possible to effectively transesterify sunflower and other types of non-standard quality oils without preliminary treatment. This will reduce the cost of production and increase the profitability of enterprises (depending on the indicators of non-standard raw materials).Документ Evaluation of Milk Productivity of Cows by the Chest Width behind the Shoulders(2022) Bratyuk, V.; Stadnytska, O.; Khalak, V.; Gutyj, B.; Dudchak, I.; Slepokura, O.; Kuzmenko, L.

O.; Усенко, Світлана Олексіївна; Shostia, A. M.; Шостя, Анатолій Михайлович; Ovsiannikova, T.; Falalieieva, T.; Marushko, L.; Semenko, Y.; Zygin, S.The object of the study is the process of esterification of sunflower soapstock fatty acids with butanol. Soapstock is a waste of the oil and fat industry, which is formed in the process of alkaline neutralization of oils. The processing of soapstock to obtain fatty acids is promising, since the disposal of waste is difficult and dangerous, and fatty acids are an industrially valuable product. Fatty acids obtained from soapstock are an available raw material for the production of fatty acid esters of low molecular weight alcohols, which are the basis of alternative biodiesel fuel. The influence of the conditions of esterification of fatty acids from sunflower soapstock (CAS Number 61788-66-7) with butanol (CAS Number 71-36-3) in the presence of an alkylbenzenesulfonic acid catalyst on the acid value of the reaction mixture was studied. This indicator reflects an increase in the content of butyl esters. The fatty acids used, obtained from soapstock by decomposition with sulfuric acid, meet the requirements of DSTU 4860 for first-grade fatty acids. The neutralization number of fatty acids is 186.0 mg KOH/g, the mass fraction of moisture and volatile substances is 1.7 %, the mass fraction of total fat is 97.5 %, the depth of cleavage is 67.1 % of oleic acid. Rational conditions for the esterification process have been established, which correspond to the maximum reduction in the acid value of the reaction mixture: duration is 12 hours, catalyst concentration is 3.5 %. In this case, the acid value of the reaction mass was 4.05 mg KOH/g. The product yield was 91.5 %. Product parameters: mass fraction of esters – 92.7 %, mass fraction of total glycerol – 0.20 %, mass fraction of moisture 0.04 %, density at the temperature of 15 °C – 840 kg/m3. The results obtained make it possible to obtain a high-quality base for biodiesel fuel using soapstock fatty acids under rational conditions.Документ Impact of immunological castration on the carcass quality of final hybrids in commercial Ukrainian pig farms(Cambridge University press, 2018-12) Povod, M.; Kodak, T.; Kravchenko, O.

M.; Usenko, S. O.; Шостя, Анатолій Михайлович; Усенко, Світлана ОлексіївнаPresented results of the comparative analysis of non-sexed and sexed sperm of the same Holstein bulls after defrosting considering: the concentration of spermatozoa in 1 ml, their motility, survival, the dynamic characteristics of the movement, the acrosome integrity (intactness), the level of microbial contamination. It has been established that the motility and survival of sexed sperm were lower by 15–20% compared with similar traits of non-sexed sperm. The sperm of the bull Vioris Sleeman HOCANM7817774 had the highest activity rate in non-sexed and sexed forms. This demonstrates the possibility of breeding bulls based on this quality trait. The experimental results indicate the necessity to improve the technology of freezing and thawing sexed bull sperm and the relevance of training specialists of breeding centers and farms in Ukraine.
