MILK PRODUCTIVITY AND TRUENESS TO TYPE OF BROWN SWISS COWS OF THE SMOLENSK REGION

Изучена молочная продуктивность коров бурой швицкой породы и определена ее производственная типичность в условиях Смоленской области. Исследования показали, что в породе преобладают животные молочного (36%) и низкомолочного (31%) типов, при этом высокомолочные коровы составляют 26% от всего поголовья. Рассчитанные усредненные значения коэффициента производственной типичности (КПТ) и индекса производственной типичности (ИПТ) находятся в пределах 3,00—3,99 ед., то есть изучаемых животных возможно отнести к классу молочных. Отмечено снижение значений результатов типичности от 1-ой к 3-ей лактации на 0,04—0,03 ед. (Р≤0,001).Экстерьер коров в зависимости от производственного типа имеет, в основном, недостоверную разницу между значениями промеров, но позволяет определить их соответствие типу. Следует отметить значительную разницу у коров всех лактаций глубины груди — 8,4—10,0 см (Р≤0,001), косой длины туловища — 5,6—8,2 см (P≤0,001). Интенсивность удоя в первую и вторую фазы лактации в зависимости от производственного типа увеличивается от 1-й к 3-й лактации. У коров всех производственных типов происходит снижение коэффициента устойчивости от 1-й к 3-й лактации и составляет 0,9—13,3%. Результаты коэффициента молочности постепенно увеличиваются от 1-й лактации к 3-й, кроме группы высокомолочных коров. Полученные данные обеспечат достоверность отбора лучших животных для дальнейшей селекции, повысят точность определения производственного типа, ускорят проведение оценки, поскольку для установления направления продуктивности животных целесообразно ее проводить по окончании 1-й лактации путем расчета КПТ и ИПТ. Итог — получение стад соответствующего направления продуктивности в зависимости от пожеланий собственника. The milk productivity of Brown Swiss cattle was studied and its trueness to type assessment was carried in the Smolensk region. The survey of the breed was showed that it is dominated by animals of the milk (36%) and low-milk (31%) types, while high-milk ones make up 26%. The observed average values of the trueness to type coefficient (TTC) and the index trueness to type of (ITT) are in the range of 3.00—3.99 points, that is, the studied animals may be classified as milk. There was a decrease the results to type from 1 to 3 lactation by 0.04—0.03 points (P≤0.001). The exterior of cows, depending on the production type, has mainly an unreliable difference between the values of body measurements, but what it allows to determine their compliance with the trueness to type. It should be noted a significant difference in the chest depth in all lactation 8.4—10.0 cm (P≤0.001), the oblique body length 5.6—8.2 cm (P≤0.001). The rate of production in the first and second phases of lactation, depending of the trueness to type, increases from 1 to 3 lactation. In all cow’s trueness to types, the coefficient of lactation stability decreases from the first to the third lactation and is 0.9 - 13.3%. The results of the milk yield coefficient gradually increase from 1 lactation to 3, except for the group of high-milk cows. The obtained results will ensure the reliability of the selection of the best animals for further breeding, increase the accuracy of determining the trueness to type, step up the assessment, since it is advisable to conduct it after the end of the first lactation by calculating the TTC and ITT to determine the direction of animal productivity. The result is the receipt of herds of the appropriate direction of productivity, depending on the wishes of the owner.

Genome structural variation in Escherichia coli O157:H7

The human zoonotic pathogen Escherichia coli O157:H7 is defined by its extensive prophage repertoire including those that encode Shiga toxin, the factor responsible for inducing life-threatening pathology in humans. As well as introducing genes that can contribute to the virulence of a strain, prophage can enable the generation of large-chromosomal rearrangements (LCRs) by homologous recombination. This work examines the types and frequencies of LCRs across the major lineages of the O157:H7 serotype. We demonstrate that LCRs are a major source of genomic variation across all lineages of E. coli O157:H7 and by using both optical mapping and Oxford Nanopore long-read sequencing prove that LCRs are generated in laboratory cultures started from a single colony and that these variants can be recovered from colonized cattle. LCRs are biased towards the terminus region of the genome and are bounded by specific prophages that share large regions of sequence homology associated with the recombinational activity. RNA transcriptional profiling and phenotyping of specific structural variants indicated that important virulence phenotypes such as Shiga-toxin production, type-3 secretion and motility can be affected by LCRs. In summary, E. coli O157:H7 has acquired multiple prophage regions over time that act to continually produce structural variants of the genome. These findings raise important questions about the significance of this prophage-mediated genome contingency to enhance adaptability between environments.

Possibilities of Water Storage in Drainage Channel System of the Upper Rye Island

Consequently, to the construction and operation at water power plant Gabcíkovo came to changes in water regime in adjacent area. The power canal of the Gabcíkovo power plant cut the upper parts of the drainage system in Danube Lowlands. Groundwater level changes have occurred in the vicinity of the Hrušov reservoir what caused changes in discharge and water level regime of the drainage channels. Presented contribution deals with theoretical and practical background of the water management in agriculturally exploited regions, especially with the possibility to create and store enough water for irrigation in the channels of one part of the Rye Island. It was therefore necessary to measure and calculate the capacity of given channels as well as the volume of water stored by means of improved operation on hydraulic structures or by construction of new structures. Rye Island belongs to an area where agriculture in the growing season, especially due to the irregular distribution of precipitation, very often suffers from drought. The probability of ensuring at least 10 mm of precipitation in one decade of the growing season is only 50% and the probability of 30 mm of precipitation is only 20%. It follows that without irrigation the moisture for vegetation cover is not ensured. But there can be years with heavy rainfall and then there is no need to irrigate. Rye Island is the warmest area of the Slovakia where the vegetation period is also the longest. Most of it belongs to the area of corn production type. The irrigation economy is therefore profitable. However, the technology of implementation and the effort to introduce large-scale irrigation as soon as possible led to the conclusion that this issue should be considered from several points of view.

Economic and statistical analysis of labor resources of agricultural organizations according to departmental reporting

The article provides an economic and statistical analysis of labor resources by types of agricultural organizations (AO), allocated taking into account both the provisions of the Federal Law 209-FZ, dated 24 July 2007, “On the development of small and medium-sized businesses in the Russian Federation”, and specialization of agricultural organizations i.e., by production type (based on the author’s approach). The subject of the research is the system of statistical indicators of the availability, composition and, use of labor resources. The object is the aggregate of agricultural organizations of the Lipetsk region. The information base of research is the departmental reporting forms “On the financial and economic condition of agricultural producers in 2019”. The scientific novelty of the research consists in the substantiation of the system of indicators and the development of methods of analysis of labor resources by types of agricultural organizations, as well as in assessing the influence of the capital-labor ratio on the level of labor productivity based on the construction of the power functions.

THE IMPORTANCE OF AGRICULTURE FROM AREAS WITH ESPECIALLY UNFAVORABLE NATURAL CONDITIONS IN POLAND IN THE CONTEXT OF THE EUROPEAN GREEN DEAL

The aim of the study is to characterize agriculture in areas (communes) with particularly unfavorable natural conditions for farming, as well as to assess the production potential, organization of production and economic situation of farms from such areas in Poland. The first part of the study describes the characteristics of agriculture in communes with particularly unfavorable natural conditions. For this purpose, data from the Institute of Soil Science and Plant Cultivation in Puławy, on the average value of the index of Valorization of Agricultural Production Area (VAPA) in communes in Poland, was used. Communes with particularly unfavorable natural conditions were those with an average VAPA index below 52 points out of 120 possible points. The organizational and economic assessment of farms according to production types was also carried out: field crops, grazing animals, and farms with mixed plant-animal production in communes with an average VAPA index lower than 52 points against a background of similar farms from other communes that have continuously kept accounting for Polish FADN in 2017-2019. It was found that communes with unfavorable natural conditions, compared to other communes, were distinguished by a smaller average utilized agricultural area (UAA) on farms, a smaller share of arable land and a greater permanent grassland in UAA, as well as e.g., a lower share of wheat and rape in total and higher total rye in the crop structure. They had, however, a greater share of land used ecologically in total UAA. They also had a higher density of livestock per 1 ha of UAA. In turn, farms from these areas – regardless of the analyzed production type, as compared to other farms, were characterized by a smaller UAA, incurred lower labor input per farm, and had a lower capital value. They also had significantly lower land and labor productivity as well as income per 1 FWU.

The influence of extreme weather events on farm economic performance – a case study from Serbia

Western Balkan region, particularly Serbia, is faced with an increased frequency of extreme weather events, as a consequence of global climate change. However, there is still no enough research on how the effects of extreme weather events could be measured on the farm level. More importantly, there is no standard international methodology that is used regularly to address the issue. Therefore, the aim of this research was to evaluate the effects of extreme weather events on business performances of two the most common farm types in Serbia. To achieve this goal, the authors performed a financial loss assessment on a farm level. Panel models and R software environment were used to perform a multiple regression analysis allowing to indicate determinants of financial loss indicator depending on the farm’s production type. The results indicated that performance of both farm types is more influenced by drought than by floods. The regression analysis revealed that for both farm types financial stress is the most important independent variable.

Epidemiological study on foot-and-mouth disease in small ruminants: Sero-prevalence and risk factor assessment in Kenya

Foot-and-mouth disease (FMD) is endemic in Kenya affecting cloven-hoofed ruminants. The epidemiology of the disease in small ruminants (SR) in Kenya is not documented. We carried out a cross-sectional study, the first in Kenya, to estimate the sero-prevalence of FMD in SR and the associated risk factors nationally. Selection of animals to be sampled used a multistage cluster sampling approach. Serum samples totaling 7564 were screened for FMD antibodies of non-structural-proteins using ID Screen® NSP Competition ELISA kit. To identify the risk factors, generalized linear mixed effects (GLMM) logistic regression analysis with county and villages as random effect variables was used. The country animal level sero-prevalence was 22.5% (95% CI: 22.3%-24.3%) while herd level sero-prevalence was 77.6% (95% CI: 73.9%-80.9%). The risk factor that was significantly positively associated with FMD sero-positivity in SR was multipurpose production type (OR = 1.307; p = 0.042). The risk factors that were significantly negatively associated with FMD sero-positivity were male sex (OR = 0.796; p = 0.007), young age (OR = 0.470; p = 0.010), and sedentary production zone (OR = 0.324; p<0.001). There were no statistically significant intra class correlations among the random effect variables but interactions between age and sex variables among the studied animals were statistically significant (p = 0.019). This study showed that there may be widespread undetected virus circulation in SR indicated by the near ubiquitous spatial distribution of significant FMD sero-positivity in the country. Strengthening of risk-based FMD surveillance in small ruminants is recommended. Adjustment of husbandry practices to control FMD in SR and in-contact species is suggested. Cross-transmission of FMD and more risk factors need to be researched.

RECENT TRENDS IN BUSINESS AND MANAGEMENT

Trade is the tertiary production type of business in economic activities and business is economic activity is also known as Pink Color Workers. In this business, mainly goods are exchanged. In short, buying and selling goods is a trade or a business. This research paper is based on the secondary information material. This research paper provides nautical analysis of the various types of current occupations and how they are managed or attempts to conduct descriptive or theoretical studies. The type of trade and its management before the industrial revolution was very different from modern times, and the development of technology after the industrial revolution led to major changes in the form and method of trade and its management, and in the 21st century the development of technology thus vary fast change of business trend and management. The main objective of this research paper is recent trends in business and management with the aim of conducting a thirty trend study. KEY WORDS: Recent Trends, Business, Management, Tertiary Production, Pink Color Workers.

Online voting behaviour, public content preferences, and content complexity of movies and digital entertainment since the late 19th century

Analysis of cinema and electronic art contents into quantifiable characteristics could provide insights on important elements of human behaviour such as voting behaviour, appreciation, and emotions regarding content. Analysis of movies, series, TV programs, and video games, were performed mining the IMBD database and merging datasets. Data analytics were performed including the relationship between the number of votes and rating, rating and content as timeseries, and multivariate statistical analysis between content and rating as well as production type and rating. Content complexity (i.e. the number of different genre) was also analyzed regarding rating. Results indicated that there is an overall positive relationship between the number of votes and rating for low, intermediate, and high number of votes, while very high number of votes is related with a partisan voting behaviour resulting in negative rating. Adult rated content is declining over the past three decades. Violent content is expressed via other forms of content through time, switching from war to horror. Diversity of content was the highest rated content type linked with diversity and complexity of feelings and emotions. Among all production types, video games were the highest rated ones related with integrative social behaviour with other users or addiction.
