For modern cattle industry, it is very important to evaluate bull-sires of different breeds by semen quality. The relevance of this problem arises in the context of development of artificial insemination technologies and biotechnology, the increasing role of sire-bulls in the genetic improvement of the herd, which makes it possible to significantly change the breed composition of herds in large regions in a short period of time. In cattle breeding, sires of Black-and-white and Holstein black-and-white breeds, which are imported into the Russian Federation, are used almost throughout the country. The purpose of the study is to assess the practical possibility of using the measured data of the bioelectric potential of superficially localized biologically active centres of sire-bulls to evaluate the quality of their semen production. The subject of the study was the semen production of the bulls of Black-and-white and Holstein blackand-white breeds. The groups were formed according to the principle of analogues; the bulls were from 2 to 4 years old; the body weight was from 700 to 800 kg. As a result of evaluating the sperm quality in sire-bulls with a high level of biopotential of the superficially localized biologically active centres, in the field of vision of the preparation, spermatozoa with an intact acrosome were found, which amounted to 96.5% of the total number of spermatozoa of the preparation and had a significant difference with the experimental group. The use of bioenergetic data of the superficially localized biologically active centres makes it possible to evaluate the sperm quality before semen collection and thereby, reduce the time and labour costs for low-quality ejaculates culling.

The objectives of this trial were to estimate prevalence of bacteriospermia, to determine the bacterial load, and to isolate the types of bacteria as well as to assess the association between bacterial load and sperm quality traits in cryopreserved bull semen in field conditions in the South Wollo Zone. A total of 309 cryopreserved straws of semen from the Holstein Friesian (HF)-cross bull (n = 180 straws) and pure Jersey bull (n = 129 straws) were investigated. Bacteriological assessments of the presence of aerobic bacteria, estimation of bacterial count and bacterial isolation, as well as semen quality were performed. Aerobic bacterial contamination was prevalent in 38.8% of the semen straws. No significant difference in the prevalence of bacteriospermia was observed among bulls although the HF-cross bull had a higher prevalence (40.0%). But, significant difference in prevalence of bacteriospermia was found among semen ejaculates of the same bull. The risk of bacteriospermia in the HF-cross bull was higher (Odds ratio = 1.86, 95% CI = 0.168–20.26) compared to Jersey although not significant. Overall average bacterial load of 50.38 ± 16.29 colony-forming units (CFU)/ml (from nil to 1318.20 CFU/ml) was found. No significant difference in bacterial count among bulls and their ejaculates was observed. Moreover, correlation analysis revealed that the proportions of motility, live, and normal morphology were negatively influenced by an increase in the bacterial contamination of semen. In this study, three isolates of coagualse-negative Staphylococcus species and one isolate of Corynebacterium species were found. Average percentages of sperm motility (48.35 ± 1.23), live (66.08 ± 1.0), and normal morphology (80.62 ± 1.24) were observed. It was concluded that cryopreservation does not guarantee the quality of semen from bacterial contamination. Hence, meticulous care should be adopted to prevent contamination of semen by bacteria during collection, transportation, processing, and storage times.

Background. The deficiency of essential nutrients in the human body is the root cause of reduced efficiency, general resistance of the body to various diseases. That is an urgent problem in the context of the spread of coronavirus infection. In this regard, the search for opportunities to meet the needs of the population in food products that contain biologically active substances (BAS) through the use of high-value and at the same time available plant raw materials is extremely important. Marigolds attract special attention among such raw materials. The aim of the work is to study the chemical composition and evaluate the consumer properties of Tagetes L. varieties, zoned in the Kiev region, to prove the possibility of increasing the biological value of pasta by adding to their recipe powder from marigold inflorescences. Materials and methods. The object of research is pasta of B group (noodles). Inflorescences of marigolds of different varieties gathered during the flowering period in July-September 2019–2020 in the territory of Vasylkiv and Obukhiv districts of Kyiv region, Ukraine were used as enriching plant raw materials. The quality of finished pasta was assessed by organoleptic and physicochemical indexes (moisture content and titratable acidity). The content of mineral elements in the fine powder of marigold inflorescences was determined on the EXHERT-3L device, the quantitative composition and BAS identification – by spectrophotometric analysis on the device Specord-200 Analytic Jena UV-vis. The integrated quality index of pasta products was calculated taking into account the importance factors of individual indexes. Results. Comparing the obtained results, we can state that all the studied varieties – Gold Kopfen, Orange Flame, Hawaii, Equinox are characterized by high biological value, regardless of the area of collection. As a result of calculated and experimental studies it was determined that the addition of 7 % of the supplement does not provide the required supply of vitamins and minerals. Replacing the flour in the recipe by 20 % significantly improves the mineral composition, but deteriorates the taste and aromatic properties of pasta. The most optimal and rational amount of added additive is 15 %, as it improves the organoleptic properties of pasta and enriches their BAS. Conclusion. The usage of non-traditional vegetable raw materials, in particular powder from marigold inflorescences, which is rich in biologically active substances, allows not only to expand the range, improve the quality of finished products, but also increase the biological value of the product. The optimal amount of additive –powder from marigold inflorescences, was defined. It is 15 % by weight of flour in the production of noodles. This concentration allows not only to improve the organoleptic properties, but also to increase the content of biologically active substances – vitamins, micro- and macronutrients. The usage of non-traditional natural raw materials (powder from marigold inflorescences) allows to abandon artificial colorsand give the finished pasta a pleasant colorand aroma.

The results of AI depend on many factors, with the quality of semen being one of the most important. Not all male hybrids can meet the requirements for semen quality, because they often have reduced fertility following cryopreservation. Thus, it is necessary to improve semen processing before use in AI. The aim of the study was to evaluate the effectiveness of using the “swim-up” flotation method to improve sperm quality of hybrid males of the Ovis genus. Semen from interspecific hybrid rams (1/4 Argali×3/4 Romanov, n=15; 1/8 Argali×7/8 Romanov, n=15) was freshly obtained, frozen–thawed, and processed by the swim-up method. Evaluation of sperm motility was determined using computer-assisted semen analysis. Statistical analysis was performed using SPSS vs.15.0 (ANOVA and t-test; SPSS Inc.). Semen was collected during the breeding season (October–December) via artificial vagina. Assessment of acrosome integrity was determined using differential staining with a Diachem diff-quick kit (NPF ABRIS+). The degree of sperm DNA fragmentation was determined using the acridine-orange test. The sperm freezing/thawing cycle was accompanied by sperm damage and an increase in the proportion of immobile sperm from 10 to 58%, with non-progressive movement increasing from 9 to 19.3%. The number of spermatozoa with abnormal morphology doubled, and the DNA fragmentation index increased from 16 to 26%. Use of the swim-up procedure allowed us to sort progressively motile spermatozoa. The content of progressively motile spermatozoa in the samples obtained from the supernatant was 86%, which was 2.3 times higher than in frozen–thawed sperm (P≤0,01). The obtained results show the effective use of the swim-up procedure to determine the quality of semen in hybrid rams. These studies were carried out with financial support from the Russian Science Foundation, grant No. 18-16-00079 and the Ministry of Science and Higher Education of the Russian Federation.

Inbreeding depression, a genetic condition produced by the mating of close-related individuals, has been associated with a reduction of fertility in several species. However, a loss in sperm quality was also associated with age. In horses, the few existing reports have described a tendency of both parameters to produce a negative effect on sperm quality. However, those reports were performed using a subjective evaluation of sperm motility. In the present study, a total of 692 ejaculates from 86 Pure Spanish stallions (PRE), aged between 3 and 22 years, were evaluated using a computer-assisted methodology to determine the effect of inbreeding in four semen parameters: free-gel volume (V), sperm concentration (C, by haemocytometer), and total (TM) and progressive (PM) sperm motility (by Spermvision sperm class analyser; Minitube). The inbreeding coefficient (F) was estimated using 300 000 PRE pedigree records approximately (minimum pedigree depth, eight equivalent complete generations; range, between 1 and 30.1%). Stallion, age, ejaculate, and season of semen collection were the variables included in the statistical model (general linear model), with ejaculate and season being the variables with a major effect (by variance components analysis). Our results showed that sperm concentration (r=−0.18; P&lt;0.0001) and volume (to a lesser extent) were reduced with advancing age, both showing a major decline after 15 years of age. To the contrary, sperm motility was not affected by age of the stallion. We also found a negative correlation between the inbreeding coefficient and ejaculate volume (r=−0.14; P&lt;0.001), with a marked decrease seen when F was between 7 and 20%. Also, a negative correlation was observed in PM (r=−0.08; P&lt;0.05), although to a lower extent. Conversely, C and TM were not affected by inbreeding depression (P&gt;0.05). In conclusion, our results demonstrated that high levels of inbreeding can compromise severely the sperm quality of the PRE stallion, which, subsequently, may have a negative influence on fertility. Ongoing studies using genomic data will help to detect genetic variants associated with stallion semen quality and how it is influenced by inbreeding in specific genomic regions.

Background: Uveal melanoma and its treatment can influence the physical and psychological well-being of patients in a way that differs from other cancers. Factors influencing quality of life (QOL) include visual impairment, changes in appearance, day-to-day functioning, ocular discomfort, and worry regarding disease recurrence. Objective: We aimed to study both general and disease-specific QOL in uveal melanoma patients in Ireland and compare QOL between a plaque radiotherapy group and an enucleation treatment group. This information was sought to enhance our understanding of QOL issues for uveal melanoma patients, in the context of improving care and providing appropriate psychosocial support. Method: The European Organisation for Research and Treatment of Cancer (EORTC) QOL questionnaires QLQ-C30 and QLQ-OPT30 were completed by patients with uveal melanoma treated by enucleation or brachytherapy. Results: 138 of 206 patients completed the questionnaires. There was no significant difference in QOL scores between treatment groups. Thirty-two percent of patients reported concerns about tumour recurrence elsewhere in the body. The brachytherapy group had a significantly higher “role functioning” score (p = 0.030). Enucleation patients were more likely to have problems with appearance (p < 0.0005). Younger patients (12–54 years of age) were more likely to report headaches (p < 0.0005) and problems with reading (p = 0.042), and they had a lower cognitive functioning score (p = 0.003) than those aged ≥55 years. Conclusions: There was no significant difference in reported QOL between treatment groups. Our data identified a number of vulnerable patient subgroups. By anticipating which patients are more likely to suffer in terms of certain aspects of their QOL, we are better able to provide appropriate and timely psychosocial support.

Semen quality of cocks is of utmost importance in reproduction. Breeding method, breed, strain and genetic constitution are the major components of the genetic factors capable of affecting the semen quality of cocks. This research seeks to determine the effect of genotype on the semen quality traits of 272 F crossbred cocks produced at day-old by main and 1 reciprocal crossbreeding of 69 Isa Brown and local frizzle feathered, naked neck and normal feathered chickens. The genotypes of the cocks were Isa Brow x frizzle feathered main cross (IBxF), Isa Brown x naked neck main cross (IBxNa), Isa Brown x normal feathered main cross (IBxN), frizzle feathered x Isa Brown reciprocal cross (FxIB), naked neck x Isa Brown reciprocal cross (NaxIB) and normal feathered x Isa Brown reciprocal cross (NxIB). At 36-40 weeks of age, semen was extracted from the cocks by abdominal  massage technique and used to evaluate semen volume (SV), sperm motility (SM), sperm concentration (SC) and live sperm (LS) at weekly intervals. Data obtained from the evaluation were subjected to analysisof variance and tested at 5% level of probability. Genotypes differed significantly (P <0.05) in SC at 37-40 weeks and in SM and LS at all ages. There was no significant difference (P>0.05) in SV. Regardless of genotype and age, the mean SV, SM, SC and LS ranged from 0.31±0.02 to 0.24±0.01ml, 71.84±1.33 to 58.75±2.16 %, 3.22±0.02 to2.92±0.02 x109/ml and 71.91±1.37 %, respectively. The NxIB and IBxNa genotypes produced largest numericalsemen volume at 37 and 39 weeks of age respectively. Whereas SC and LS were significantly highest for IBxF and IBxN respectively at week 37, SM was so for IBxN at all ages. Further, the LS of IBxN genotype was significantly highest at 36-38 and 40 weeks of age. The exotic Isa Brown and normal feathered main cross cocks exhibited the best semen quality traits among all genotypes studied and should be selected for improvement of the reproductive characteristics of cocks.
