The purpose of the study is to examine the productive and slaughter indicators of bulls of imported meat breeds of various ecological and genetic origins in the climatic conditions of the steppe zone of Ukraine. Zootechnical, morphometric, biometric, and statistical methods were used in the research. The results of an analysis of the meat productivity of bulls of imported meat breeds of Maine-Anjou, Chianina, and Santa Gertrudis in the age aspect in the conditions of the steppe of the Dnieper region of Ukraine are presented. It was identified that when slaughtering experimental animals at the age of 18 months, the mass of paired carcasses of Maine-Anjou and Chianina was quite high and amounted to 324.2 and 311.3 kg, respectively, and the Santa Gertrudis – 233.3 kg, which is 1.39 and 1.33 times less than the young animals of Maine-Anjou and Chianina, respectively. It is proved that to use livestock more efficiently and obtain high-quality beef to improve the supply of meat to the population, it is advisable to grow them up to 18-24 months of age. Maine-Anjou animals dominate in terms of growth energy, age of reaching live weight during key growing periods, and feed conversion. In addition, due to the pronounced massiveness and habit of the body, have a larger carcass mass, the amount of internal fat, offal, as a result of which, the slaughter yield is higher. Based on the conducted studies, the possibility of effective breeding of Maine-Anjou bulls up to 12 months of age is proved, since during this period they reach a live weight of 400 kg and are characterised by the high production rate of lean beef, and for Chianina breed – up to 18 months of age and bigger weight conditions","PeriodicalId":52817,"journal":{"name":"Naukovi gorizonti","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44248993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the differentiation of soil and climatic zones of cultivation, the breeding process is designed to establish hybrids of different maturity groups. The research purposes to evaluate maize hybrids of different maturity groups for a set of economic and biological traits of productivity, high-yield stability, and further cultivation in production conditions suitable for mechanised harvesting. Methods used in the research include informational, theoretical analysis, synthesis, analogy, comparison and generalisation; research identification, and measurement. During the research, a systematic analysis was applied, considering the uniqueness of technical, productive, and economic conditions for growing hybrid corn. The research results demonstrate that to achieve successful regulation of maize hybrids productivity and improve their quality, it is necessary to select for suitability for specific soils and climatic zones, considering the biological requirements for seeds and developing effective agrotechnical means designed for processes occurring at different stages of growth and development. The seeds of corn hybrids, formed by breeding, were determined by a high nutrient content: In mid-early corn, the content of crude protein was 9.2-9.9%, crude fat – 4.2-4.4%, BER (nitrogen-free extractives) – 82.5-83.3%, starch – 71.4-73.7%; in the medium-late group, the content of crude protein ranged from 9.8-10.4%, crude fat from 4.1-4.6%, BER from 80.6-82.2%, and starch from 70.2-74.1%.

The relevance of the subject under study is due to the need to increase the reliability of the stress-strain state assessment during the plastic processing of porous workpieces by clarifying the porosity functions. The purpose of the study is to develop a method for describing the mechanical characteristics of porous bodies by single functions, the nature of which is determined by the properties of the base material and does not depend on the initial porosity. Analytical, numerical, experimental, and computational methods using modern specialised software systems were used to examine the processes of plastic deformation. The study presents a method for describing the mechanical characteristics of porous bodies with single functions. A set of interrelated methods and techniques is based on the basic provisions of the mechanics of plastic deformation of porous bodies and allows obtaining reliable porosity functions for this material, by clarifying theoretical dependencies by experimental studies. Therewith, experimental data were obtained in experiments on axisymmetric upsetting of cylindrical samples without friction at the ends. Based on the conducted theoretical studies, porosity functions for iron-based materials are obtained. Samples of five different initial porosities were used for the study. As a result of processing experimental data, final expressions for the porosity functions of the iron-based powder workpiece material are obtained. The study also presents a method for calculating the accumulated deformation of the base material. Flow curves for iron-based powder materials are plotted.

This is caused by an increase in air pollution, wastewater pollution, wood burning, and others. Since 2013, ammonia emissions by European Union companies have increased significantly. This was facilitated, among other things, using synthetic pesticides. That is why the transition of agriculture to organic farming standards can be considered a good alternative. The aim of the study was to analyse the effectiveness of combining known organic pesticides in one biogeocenosis. A combined treatment of the vegetable crop Brassica oleracea with such biological pesticides as Bacillus thuringiensis and pyrethrin, combined with mass pest trapping, is proposed in the research. When combining these three approaches, the efficiency was 93%. The total crop yield was 27 tons/ha, while the area of the field where pheromone and yellow sticky traps were used had a yield of 34 tons/ha. These methods were effective against the following pests: Ceutorhynchus rapae, Aleyrodes proletella, and Brevicoryne brassicae. Leaf damage was reduced by 93% on average during the study period when using the combined approach. During the two-year research, it was possible to neutralize 1882 insects by mass trapping and find out that the largest number of Ceutorhynchus rapae affect the crop in May and August, but the use of pheromone traps is most effective in October. The combination of individual methods increased the effectiveness of each method due to the synchronized impact on different pests. Increasing vegetable yields in Albania in the future can also solve the problem of hunger in countries with unfavourable climatic conditions by increasing the export of these crops","PeriodicalId":52817,"journal":{"name":"Naukovi gorizonti","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46286482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is known that radiation exposure leads to autosensitisation of the body by the breakdown products of its tissues and the development of non-specific (false) immunological reactions. Therefore, the purpose of the study was to examine the immunological (serological) reactivity of tuberculosis patients exposed to gamma radiation in laboratory animals. Radiological, bacteriological, allergic, serological, and pathoanatomical research methods were used in the study. Guinea pigs were consistently irradiated with various doses of gamma rays, infected with Mycobacterium tuberculosis of various types, and, for 90 days, were examined by clinical, allergic, pathoanatomical, and serological methods in the complement fixation reaction (CFR) and passive hemagglutination reaction (PHGR) according to Boyden to detect antitubercular complementbinding antibodies and tissue autoantibodies. 45 and 90 days after infection with M. bovis and M. tuberculosis antitubercular complement-binding antibodies were recorded in serum samples of irradiated and non-irradiated animals in diagnostic titres (1:20-1:80), which indicates the active development of the infectious process. In irradiated and intact guinea pigs infected with M. avium, no anti-tuberculosis antibodies were detected in since guinea pigs are not susceptible to infection with the causative agent of avian tuberculosis. In serum samples from uninfected guinea pigs, both irradiated and intact, antitubercular complement-binding antibodies were not detected during the entire follow-up period (90 days). The high content of tissue autoantibodies in blood serum samples of animals irradiated with a dose of 200 R (0.0516 C/kg) is a manifestation of autosensitisation of the body by the breakdown products of its tissues due to radiation damage. The presence of tissue autoantibodies in blood serum samples of irradiated and Mycobacterium-infected animals did not affect serological indicators for the indication of anti-tuberculosis antibodies, which should be considered when conducting diagnostic studies by veterinary medicine laboratories","PeriodicalId":52817,"journal":{"name":"Naukovi gorizonti","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49191159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research was performed using pathological and anatomical dissection and histological studies. It was established that damage to the cervical spinal cord due to traumatic bending of the neck was accompanied by partial or complete rupture of the intervertebral disc and destruction of the ligaments of the vertebrae. It was found that the hyperemia of the vessels of the meninges of the brain is the result of blood circulation disorders in the occipital artery and the caudal artery of the meninges, and mechanical damage to the integrity of the intervertebral discs or the destruction of the ligaments of the neck vertebrae led to various disorders of the innervation of various organs and systems of the body and ended the death of animals. It was proved that the distraction injury of the cervical spine led to the swelling of the medulla of the brain, haemorrhages of the caudalventral part of the brain substance.

At the same time, the seed production helps to increase profitability per hectare; however, it can be observed the opposite trend in terms of efficiency per unit of capital invested, which was higher for producers of commercial grains than seeds. With that, the specifics of seed production impose higher requirements on agricultural producers in terms of energy efficiency, namely the provision of machine-tractor fleet and fleet of agricultural machinery, storage facilities, as well as equipment for cleaning grain.

Highly productive cows are quite demanding of the indoor microclimate and conditions of keeping. It is believed that the productivity of animals by 10-30% depends on this. The purpose of the study was to examine the possibility of reducing the influence of high ambient temperature on the milk productivity of cows by different approaches to the organisation of their feeding technology. The paper uses analytical, diagnostic, physicochemical, and statistical research methods. The main climate indicators were monitored during the summer period (June-August). It is established that the decrease in daily milk yield is a consequence of the negative influence of the temperature factor when the daily (from 1100 to 1700) air temperature in June-July is at the level of +26-30°C. At an air temperature of 26.5°C (about 1400), the body temperature of cows rises from 37.5-37.8°C to 38.20-38.46°C. The proof of this is a decrease in the rate of decline in the level of milk productivity of cows of the experimental groups in August when the average daily air temperature dropped to +24-26°C. It is proved that the introduction of 1.5 kg of protein feed additive with protected TEP-mix protein into the diet of highly productive cows increases the productivity of experimental cows (in terms of basic milk) by 15.7% (4.3 kg). Modernisation of the diet of feeding highly productive cows by increasing the content of non-broken down protein in the rumen to normal during temperature stress contributed to better adaptation of animals in terms of productivity and quality indicators of milk: an increase in the mass fraction of fat by 0.67% and the mass fraction of protein by 0.26%, with the content of somatic cells of 285.06±81.0–409.3±134.3 thousand/cm3","PeriodicalId":52817,"journal":{"name":"Naukovi gorizonti","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48339247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite substantial research, the number of high-yielding varieties adapted to specific soil and climatic conditions is insufficient. Therefore, the examination of the genetic diversity of red fescue plants is the main stage in the creation of new varieties. The purpose of the study was to evaluate samples based on the main economic-biological characteristics and divide them into three groups of ripening for further use in breeding as a source of valuable traits. The study used general scientific (analysis, synthesis, experiment, description, observation, and comparison), field (phenological observations and accounting), and statistical methods. According to the results of the study, populations of different ecological and geographical origins created by different breeding methods were similar. The coefficients of variation in the parameters of the main features were in the range of 0.34-8.02% and depended on the biological and ecological characteristics of the samples. According to the duration of the growing season, the samples were divided into early-ripening (16 pcs.), medium-ripening (20 pcs.), and late-ripening (12 pcs.). When clustering by eight features, all samples were divided into three clusters.
