As other peaberrys, Gayo peaberry arabica coffee is very attractive because it has single larger and rounder seed. It is believed that the peaberry has superior flavor profile such as more fragrant aroma, stronger flavor, and denser than other arabica coffees. The purpose of this study was to evaluate the Gayo peaberry arabica coffee by using the analytical hierarchy process (AHP) method. Three varieties of Gayo peaberry arabica coffee were investigated i.e., Tim-tim, Bor-bor, and P88, while the processing method used were semi-wash and fully-wash methods. The sensory parameters observed included fragrance, flavor, acidity, body, and sweetness. The results showed that flavor (0.338) was the most important criterion than other taste criteria (fragrance 0.241; sweetness 0.196; acidity 0.115; and body 0.111). The variety that had the highest product acceptance rate was the Tim-tim variety processed by a full-wash method with a value of 0.203. The overall result of data analysis was acceptable because it had a consistency ratio below 0.1 (10%).

Background. Coumarins are natural compounds (secondary metabolites of plant origin) that have a wide range of biological activity, mainly due to their ability to interact with various enzymes and receptors in living organisms. The relevance of their use in feeding poultry is obvious, in view of the active search for alternatives to feed antibiotics. The aim of the study was to evaluate the effect of coumarin on the productivity and antioxidant status of broiler chickens. Materials and methods. Objects of study: broiler chickens of the Arbor Acres cross, 7-hydroxycoumarin. The experiment was carried out on 180 heads of 7-day-old broiler chickens (n=45). Control - the main diet (OR), 1 experimental – OR + coumarin (at a dose of 1 mg/kg of feed/day, 2 experimental – OR + coumarin at a dose of 2 mg/kg of feed / day, 3 experimental – OR + coumarin in at a dose of 3 mg/kg feed/day. Hematological parameters (number and type of leukocytes) were taken into account on an automatic hematological analyzer URIT-2900 Vet Plus (URIT Medical Electronic Group Co., Ltd, China). Biochemical analysis of blood serum was performed on an automatic biochemical analyzer CS-T240 (Dirui Industrial Co., Ltd, China). Results. The inclusion of 7-hydroxycoumarin in the diet contributed to an increase in live weight in the experimental groups by 8,6–19,4%; (by 9,2–21,1%), slaughter yield (up to 4,76%), against the background of a decrease in feed consumption per 1 kg of live weight gain (by 3,5–15,7%). showed a decrease in total protein, albumin, ALT (groups 1 and 2 (p≤0,05)), bilirubin (by 38,3–68,6%), cholesterol (in group 3 by 16,4% (p≤0,05)), triglycerides (groups 1 and 2, p≤0,05), urea (41,8–65,1%; p≤0,05), against the background of elevated iron levels (groups 1 and 2, p≤0,05). Depending on the dose of 7-hydroxycoumarin, a decrease in the number of leukocytes (group 1, p≤0,05), neutrophils (groups 1 and 2, p≤0,05), monocytes, eosinophils and basophils (p≤ 0,05). Antioxidant indicators were characterized by a decrease in the level of malondialdehyde (by 63,7–77,3%), superoxide dismutase activity (22,4–71,5%) and an increase in catalase activity (by 24,3–46,1%). Conclusion. Thus, the inclusion of 7-hydroxycoumarin (2 mg/kg feed/day) in the diet contributed to an increase in the live weight of broiler chickens, feed intake, slaughter yield, against the background of a lower feed consumption per 1 kg of live weight gain; had a positive effect on the parameters of the liver (ALT, total bilirubin), lipid and nitrogen metabolism (triglycerides, urea), the antioxidant status of the body of broiler chickens.

Background. The study of the reaction of the immune system organs to the introduction of immunomodulators in nematodes is relevant for the development of treatment regimens. The purpose of the study was to examine the spleen (the organ of immunogenesis that plays an important role in the formation of immunity). In addition, the aim of the study was also to find the morphological changes of nematodes (capsules of trichinella larvae) and the features of siphatiа. Materials and methods. In the experiment, 35 white mice were used, which were divided into 5 groups of 7 animals in each group. The first and second groups were injected with 0.004 mg saline solution subcutaneously, the 3rd and 4th groups were injected with polyoxidonium at a dose of 0.004 mg/mouse, the 1st and 3rd groups were infected with trichinella larvae, the 2nd and 4th were spontaneously affected by syphilis, the 5th group served as control. Evaluation of the protective properties of polyoxidonium in laboratory models with trichinosis was carried out by determining the intensity of invasion during postmortem studies of all muscle groups of the animal and siphations by the number of eggs in perianal scrapings. Results. The study showed protective efficacy with the introduction of polyoxidonium was 99.43%, 57 ± 20 trichinella larvae / per animal were detected in the entire muscle mass, while only 72% with syphaciosis. The parenchyma of the organ of the spleen is a red-white pulp, in healthy animals the area of the red pulp was 70+5% of the area of the organ, and the white pulp was 26.5+ 5% of the mass of the organ. In animals infected with nematodes, the area of the white pulp increased dramatically to 50% of the organ area or more. Conclusion. Significant protective activity of polyoxidonium (99.43%) was established in parasitological studies, which was accompanied by an increase in the area of lymphoid tissue associated with the intestine. When studying histological preparations of the spleen, it was noted that the restructuring of the structure under the action of trichinella and siphacia antigens is of the same type: the ratio of red and white pulp, their cellular composition changes. It was found that in all infected animals, the area of the white pulp increased dramatically by more than 60% with trichinosis and up to 50% with syphacosis of the organ area or more. The final result of this thesis was using polyoxidonium, there was also a decrease in the number of eggs in the control group and changes in the number and actual distribution of trichinella larvae in various muscle groups.

This article is devoted to the results of the study of the relationship between subjective age and subjective assessment of health among women with breast cancer. The analysis of the literature showed that subjective age is a predictor of death, mental wellness, assessment of life prospects (approach of death), possibility of coping with a bad trauma (e.g. oncological disease). The research included 170 women in the age of 31 to 85 (the average age is 56,5) diagnosed with breast cancer on different stages. Summarising received data, it should be noted that the women who feel rather danger than their chronological age address to own resources and, in general their subjective health assessment is connected with role functioning based on the emotional condition and general mental health. The women with adequate perception of their age have issues with role functioning connected with physical condition as well as the women who feel older than they actually are do. The results of this research expand a notion about potential predictors for breast cancer course, besides the results can be used for building the forecast of the disease course and its outcome.

The strategy for the conservation of genetic diversity involves the cultivation of unique native breeds of animals. Tuva coarse-haired goats are relatively prolific, moderately early maturing, and, in addition to good meat productivity, have unique economically useful traits - very thin fluff. The purpose of the study was to study the productive indicators of Tuva coarse-haired goats and goats to identify age-related features of the morphometric parameters of the coat using an OFDA-2000 optical analyzer of the diameter of wool fibers. 18 months (n=20). The length of the down is 5.14±0.33 cm and 4.45±0.15 cm in goats and goats, respectively. The proportion of downy hair (diameter less than 30 µm) in the staple ranges from 85.0±1.23% to 87.37±1.34%. The amount of transitional hair is at the level of 3.85±0.82-4.62±0.65% (Cv 62.51-79.90%). With age, the animals tend to coarsen the fibers, this is evidenced by both the shift of the histogram peak from 16.20±0.40 µm in goats to 17.43±0.43 µm in goats, and changes in the structure of hair related to the awn ( goat wool contains 7.2 times more fibers with a diameter of more than 90 microns), We believe that when selecting Tuva goats to obtain high-quality down with the smallest fiber diameter, special attention should be paid, in addition to the length of the down and its diameter, to the presence of a transitional hair type (30.1-52.5 µm).

The given research aims to study the way meat productivity in special-purpose beef bull calves of different DGAT1 genotypes is developed. The scientific novelty of the research lies in the fact that an assessment of the meat productivity of Hereford and Limousin bulls of different DGAT1 genotypes was conducted for the first time. Calves were cultivated using elements of resource-saving technology. The research subject was Hereford male young stock (91 heads) and Limousin bull calves (109 heads), which were genotyped by SNP DGAT1-K232A. Live weight, average daily gains, and body size and conformation indices were analyzed. Hematological values and carcass quality of bull calves of different genotypes were studied. As a result of genotyping, young animals of both breeds had a similar distribution of genotypes (DGAT1KK>DGAT1KA>DGAT1AA) and alleles (DGAT1K>DGAT1A). There was no effect of the studied gene polymorphism on growth, body development, and hematological parameters, as bull calves of different DGAT1 genotypes did not show a significant difference between weight and linear growth, blood morphological parameters, the content of protein, and its fractions. SNP DGAT1-K232A was found to affect fat deposition. Thus, carcasses of both studied breeds of DGAT1K genotype had a significantly higher content of internal raw fat, and fat yield was (P<0.05) than carcasses of DGAT1AA genotype bull calves. Therefore, genotyping by SNP DGAT1-K232A can be used in the selection of special-purpose beef cattle as an additional criterion to produce meat of a higher energy value.

Objective. The article is devoted to the development of scientific and methodological provisions for improving the organizational and economic mechanism for the innovative development of the food and processing industry in order to ensure food security in Siberia. Materials and methods. The methods of substantiation of modern organizational and technological regulations, norms and standards for the innovative development of the crop industry are considered. To analyze the main directions for adjusting the organizational and economic mechanism for the innovative development of the food and processing industry in Siberia, a program-targeted approach is used. Results. An algorithm for the formation of organizational and technological regulations in crop production is considered on the example of rapeseed. The main directions for adjusting the organizational and economic mechanism for the innovative development of the food and processing industry in Siberia on the basis of a program-targeted approach are proposed. An algorithm of basic standards has been formed in the system of standards for rapeseed cultivation at different intensities in the conditions of the Novosibirsk region. Particular attention is paid to the ecological block of the economic substantiation of crop cultivation standards on the example of oilseeds. Conclusion. The current level of food consumption in the areas of development and the North of Siberia does not fully comply with modern standards and the physiological needs of the population, taking into account their national and ethnic characteristics. In this regard, the development of the food and processing industry of the agro-industrial complex of the Siberian Federal District is of strategic importance.

The article is devoted to a general review of various systems for external osteosynthesis used in modern veterinary medicine. The aim of the study was to summarize and analyze articles on the use of various systems for external osteosynthesis used in modern veterinary medicine. The analysis of the technical base of the main components of the systems under study for external (transosseous) osteosynthesis was carried out. An assessment was made of the possibility of assembling hardware structures from the parts of the systems under study from the point of view of hardware configurations. The study found: - To ensure the functional diversity of hardware combinations, the systems studied in the work use radius components (rings and their derivatives), which originate from the rings represented in the Ilizarov system. - The presence of special clamping devices in the systems expands the clinical range of application of hardware structures for transosseous osteosynthesis. - The use of rotary mechanisms in the form of brackets (cardans, hinges) expands the technological possibilities of using external fixation devices, if spatial control of hardware structures is necessary, both during operations and in the postoperative period.
