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.
Assessment of the impact of the genetic potential of different crossbreeds on egg productivity
(Кyiv : NUBiP of Ukraine, 2026-02-06) Ilchenko, M. O.; Shaferivskyi, B. S.; Ільченко, Марія Олександрівна; Шаферівський, Богдан Сергійович
This paper presents the results of an analysis of prospects for the further development of poultry farms, taking into account the existing potential and challenges of the modern poultry industry. Productivity indicators of the Lohmann crossbreeds were studied at “Poltava Poultry Farm” PJSC. The productivity of laying hens and the efficiency of using two lines – Lohmann LSL Light and Lohmann Brown – were assessed. During the laying period, Lohmann Brown hens demonstrated high adaptive capacity and stable productivity. Although Lohmann LSL Light hens adapted well to intensive housing systems, their survival rate was 2% lower than that of Lohmann Brown birds. At the same time, Lohmann LSL Light hens reached peak egg production more rapidly (91.4%) and maintained high productivity throughout the production cycle. By the end of the productive period, egg production in this cross remained at 69.1%, which was 3.6% higher than in Lohmann Brown hens.

("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 Іванівна
Marker-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.

Comprehensive research of food products, as well as compliance with the rules and regulations in the food industry, are necessary to provide consumers with quality and safe products. The purpose of this article is to provide a comprehensive analysis of the quality and safety of sour-milk cheese, including the evaluation of organoleptic characteristics, physicochemical properties, and microbiological indicators. The study was conducted with one of the largest producers of milk powder and fermented milk products on the Ukrainian market, BIAGR LLC as its basis. To achieve the set goal, the following methods were used: organoleptic, physicochemical, microbiological, and measurement of the content of toxic elements (cadmium, arsenic, lead). At the beginning of the measurement of quality indicators, packaging and labelling were evaluated, whichcomplied with the requirements of the national standard. During the study of the organoleptic quality indicators of sour-milk cheese with a fat content of 5%, it was found that its consistency is soft, without whey separation; distinctive fermented milk smell and taste are without extraneous odour and favour; the colour of the sample is uniformly white. At the second stage of the research, the mandatory physicochemical quality indicators were measured and evaluated, namely: mass fraction of fat – 5.0%; mass fraction of protein – 14.6%; mass fraction of moisture – 68.0%; titratable acidity – 176°T; phosphatase was absent. Since food safety is now an urgent issue in Ukraine, the following safety indicators were measured during the research: the number of lactic acid bacteria, which was 2×106 CFU per 1 g; Escherichia coli bacteria were not detected; the number of mould fungi was 1×101 CFU per 1 g; the amount of yeast was 1×101 CFU per 1 g; pathogenic microorganisms, including Salmonella, Staphylococcus aureus, Listeria monocytogenes were not detected.

Protozoan and helminthic gastrointestinal parasites of domestic dogs are very common invasive pathogens. Depending on the parasitic load on the body of a sick animal, the course of the infection varies from asymptomatic to severe, sometimes fatal. In the detection of various pathological conditions of the gastrointestinal tract, an important place belongs to ultrasound examination. It is the fastest, most informative and accessible method of visualization in veterinary medicine, and also allows one to safely assess the state of the abdominal organs and detect pathological changesin good time. The aim of the research was to investigate the informativeness of ultrasound examination of the stomach and small intestine in toxocariasis monoinfection and toxocariasis-cystoisosporiasis co-infection in dogs. It was found that parasitism by Toxocara canis and Cystoisospora canis led to changes in the metric indicators of the stomach and small intestine wall. Even more significant changes were found in toxocariasis-cystoisosporiasis co-infection than in toxocariasis monoinfection. In the latter case, regardless of the weight category of dogs, the changes were characterized by simultaneous thickening of the stomach wall (by 15.4–46.4%) and duodenum (by 10.3%) in dogs weighing 5–15 kg, and duondenum (by 15.1%) in dogs weighing 15–30 kg. Also, in dogs weighing 5–15 kg the thickness of the jejunum wall was reduced by 18.2–32.1%, that of the ileum as well, (by 8.0%) and the ileum wall was thinner in dogs weighing 15–30 kg (by 12.1%). It was found that all dogs infected with T. canis had a thickened submucosal layer of the stomach wall (by 42.9–50.0%) and a thinned mucosal layer of the jejunum wall (by 18.5–35.0%). In dogs weighing 5–15 and 15–30 kg, thickening of the mucous layer of the duodenal wall (by 11.1% and 8.5%, respectively) and thinning of the jejunum wall (by 20.0% and 37.5%, respectively) were detected. In toxocariasis-cystoisosporiasis co-infection, regardless of the weight category of dogs, the changes in the intestines were characterized by thickening of the gastric wall (by 33.3–67.9%), duodenum wall (by 20.9–26.5%) and thinning of the jejunum (by 24.2–39.3%) and ileum wall (by 8.2–15.2%). Changes in the walls occurred due to thickening of all layers of the stomach (by 13.6–80.0%), duodenum (by 12.6–75.0%), as well as thinning of all layers of the jejunum wall (by 20.0–45.0%). Thinning of the ileum wall occurred due to thinning of the mucous layer (by 24.0–40.0%). The obtained data confirm the feasibility of using ultrasound in the assessment of structural and functional changes in the gastrointestinal tract of dogs with mono- and co-infections.

("Regulatory Mechanisms in Biosystems", 2026-02-12) Polishchuk, A. A.; Shostia, A. M.; Usenko, S. O.; Ilchenko, M. O.; Kuzmenko, L. M.; Myronenko, O. I.; Vashchenko, P. A.; Поліщук, Анатолій Анатолійович; Шостя, Анатолій Михайлович; Усенко, Світлана Олексіївна; Ільченко, Марія Олександрівна; Кузьменко, Лариса Михайлівна; Мироненко, Олена Іванівна; Ващенко, Павло Анатолійович
Growing animal welfare concerns have intensified the need for effective and humane alternatives to surgical castration for the control of boar taint in pig production. The study investigated the effects of different castration methods on growth performance, physiological status, and meat quality of boars. Surgical castration and chemical sterilization using intratesticular administration of Canophen-B were compared with intact males. Experiments were conducted on Large White boars under controlled feeding and housing conditions in accordance with animal welfare and bioethical standards. In the first experiment, chemically sterilized and intact sexually mature boars showed similar live body weight and average daily gain. Chemical sterilization resulted in a significant reduction in serum testosterone concentration, while hematological parameters remained within physiological reference ranges, indicating no adverse effects on animal health. Sensory evaluation demonstrated that meat and broth obtained from chemically sterilized boars were free of specific odor, whereas samples from intact males exhibited a characteristic odor, particularly in broth. In the second experiment, surgically castrated boars had lower final live body weight compared with chemically sterilized and intact males. Meat yield was higher and fat yield was lower in intact and chemically sterilized boars than in surgically castrated animals. Serum testosterone levels at the end of the fattening period were highest in intact males, intermediate in chemically sterilized boars, and lowest in surgically castrated animals. Hematological indicators in all groups remained within normal physiological limits. Sensory evaluation of cooked meat revealed no statistically significant differences among experimental groups for odor, color, tenderness, taste, texture, or fibrousness. However, broth prepared from chemically sterilized boars showed significantly higher scores for transparency compared with intact males, while other sensory attributes did not differ significantly. The results indicate that chemical sterilization effectively suppresses testosterone synthesis without negatively affecting growth performance, health status, or sensory quality of meat. The absence of boar taint in products obtained from chemically sterilized males suggests that this method can be considered a viable alternative to surgical castration in pig production, combining acceptable meat quality with improved animal welfare.
Establishing the influence of sunflower oil quality indicators on the efficiency of the transesterification catalyst
(2025-12-30) Korchak, M.; Knysh, V.; Shostia, 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 Вікторівна
The 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).

Evaluation of the Genotypes of Pigs of Different Origins According to the RYR1 and LEP Genes
(Acta fytotechn zootechn, 2025) Ilchenko, M. O.; Ільченко, Марія Олександрівна
Using the polymerase chain reaction method in real-time, we investigated the polymorphism of the RYR1 and LEP genes in sows of the sizeable white breed of different origins. Following the purpose of the work, we conducted a study of the genetic structure of the above-mentioned genes in animals of French and Belgian breeds and their crossbreeds. No RYR1 gene polymorphism was detected. All experimental animals had the homozygous NN genotype. According to the genetic structure of the LEP gene, a significant difference has been established between animals of different origins. Animals of French breeding had a high frequency of the TT genotype, while in animals of other origins, this genotype did not occur at all. Accordingly, French breeding animals are characterized by a high frequency of the T allele and Belgian and crossbred animals are characterized by the A allele. In French breeding animals, there is a violation of the distribution of genotypes, according to Hardy-Weinberg. Obtaining animals of the desired genotypes among the experimental herd is possible due to the use of breeders with the appropriate genotypes for the studied genes.

(2022-11-04) Dubova, H. Y.; Levchuk, I.; Holubets, O.; Miroshnikov, V.; Дубова, Галина Євгеніївна
The article shows options for fermenting tree leaves (cherries, apricots, lindens) and berries (raspberries, currants) to obtain aromatic raw materials. The purpose of the work is to obtain a modernized technology for obtaining dried leaves with the aroma of the corresponding fruits or berries. To obtain the desired effect, the possibility of using the tea leaf preparation technology was investigated. The basis of this technology consists of three main operations of preparing the leaf for drying - partial dehydration (or cold drying), leaf rolling, fermentation in a semi-closed vessel. Further, the fermented leaves are dried according to special regimes. It was found that the technology of tea leaf preparation can be successfully used for leaves of trees and berries. Three basic operations make it possible to obtain flavored leaves. The article shows that the intensity of the aroma and its correspondence to fruits and berries to a large extent depends on the conditions for the first operation - cold drying. The result of the study is that partial dehydration can be successfully carried out in two ways - classical (sheet packing in fabric layers) and modernized (freezing followed by defrosting). The upgraded method makes it possible to simplify the subsequent twisting operation and shorten the duration of fermentationDrinks from the leaves after fermentation are an alternative or a good addition to herbal teas
