Structure of the holstein dairy cattle subpopulation in Russia by locus CSN2 and CSN3

Purpose: to determine the potential of the Russian subpopulation of the Holstein breed in relation to selection by loci of beta-and kappa-casein.Materials and methods. For loci CSN2 and CSN3, 1,539 Holstein cattle were genotyped, including 1,242 cows and heifers and 297 sires, and information on CSN2 and CSN3 genotypes of 297 US bulls was analyzed (World Wide Sires, Ltd).Results. It has been established that in the last two years there has been an increase in the percentage of sires in WWS with CSN2 genotypes A2A2 and CSN3 genotypes BB. Thus, sires allele frequency in the 2019 catalog was 0.51 and 0.29, respectively; and in the 2021 catalog was 0.68 and 0.31, respectively.Genotyped sires of domestic breeding organizations, which are mostly foreign origin, were characterized by predominance of the A2 allele CSN2; in this group the frequency of the allele was 0.63. However, the CSN3 B allele in the group of sires belonging to domestic organizations was found with a frequency of 0.34, which is 1.6 times lower than that of sires of American origin.In the genotyped group of Holstein cows and heifers (n = 1242) belonging to 3 large farms in the Krasnodar Krai, the gene frequency CSN2 allele A2 was minimal (0.57), and the CSN3 allele B (0.40) was higher than the allele frequency in the sires group of domestic breeding enterprises.Conclusion. At present, Russian breeding enterprises and farms are lagging behind in these indicators, however, by conducting targeted selection in accordance with the indicated trend, by selecting the appropriate breeding bulls, it is possible in the next generation to increase the proportion of animals carrying valuable genotypes.

Understanding Farm Diversity through Typology for Technological Interventions in Western Plain Zone of Uttar Pradesh, India

The farming systems having diverse characteristics need to be understand for tailoredtechnological interventions. Farm typology designates the heterogeneous farmers’characteristics in to homogenous groups to understand the factual situation in the region.The multivariate analysis viz. PCA and Cluster analysis performed to minimize data andgroup them into homogenous characteristics by various farm variables. A cross sectionsurvey of 120 farmers in WPZ of Uttar Pradesh was carried out and identified 9 significantvariables and generated 4 PCs from PCA. Hierarchical clustering of PCs leads to groupingfarms into homogenous class. The predominant farm types based are type-1 (22.5%)livestock based intensive farms, type-2 (23.3%) are resource endowed large farms, type-3(10.8%) are crop based marginal farms and type-4 (43.3%) are small farmers with highprofit margin. Large farms are integrated with crop and animal components earning higherincome. The results show that the diversified farms with both livestock and crop sectorsare reaping better income and technology adoption capacities.

Effect of Exogenous Factors on Transformation Processes in the Russian Agro-Industrial Complex

The purpose of the research is to study the trends of transformation of forms of management in the Russian agro-industrial complex in the conditions of preserving the general contradictions of the development of small and large forms of management. The main objective is to analyze the Russian agro-industrial complex. The subject of the study is the forms of management and the trends of their development. The last two decades are considered as the main time horizon of the study. The study made it possible: firstly, to reveal a stable tendency towards the predominance of large farms in the structure of production and the dynamics of output volumes given the existing institutional factors; secondly, to determine scenario forecasts (conservative, basic and optimistic) of the main trends in the further development of small and large forms of management; thirdly, to show the influence of the phenomenon of a global pandemic on transformation processes in the Russian agro-industrial complex. The relevance of this study is since during the thirty years of the market transformation of the national system of agrarian relations, significant changes have occurred among the main economic entities: especially in the issues of the evolution of the content, motivation of activity, sustainability factors and classification criteria for economic entities engaged in the production of agricultural products. These processes are reflected in the solution of common strategic problems: issues of ensuring both national food security and global food security issues

Veterinary and hygienic methods of directed reproduction in formation of healthy herds of cows

Our work provided for the study of the impact of directed reproduction of cows on the formation of highly productive healthy herds in the basic farms of the Republic of Kazakhstan. For accelerated replacement of herd and increase of number of highly productive cows in large farms for milk production one uses sexed semen at the first and the second insemination of primiparous cows obtained from highly productive mothers. The efficiency obtained from using this technique is 65-95% of individuals of the desired sex. Insemination was carried out by recto-cervical method using a tool AlphaVision frozen-thawed sexed semen divided by sex. The highest results of the fruitfulness of insemination with sexed semen in Agricultural production cooperative “Breeding Plant Almaty”, Individual entrepreneur “Karimov” and Kakpatas Kordai were obtained in the autumn-winter period and ranged from 58.1 to 65.2%, with an insemination index of 1.58-1.72. Economic efficiency when using the technology of artificial insemination of calves with sexed semen amounted to 10,040.2 tenge. When using sexed semen, an average of 92% of calves were obtained from bovine. Less insemination costs, the profit from calf production amounted to 76,109.2 tenge.

Ranchers or pastoralists? Farm size, specialisation and production strategy amongst cattle farmers in south-eastern Kazakhstan

Against the global trend towards sedentary, specialised and feed-intensive cattle farming, we explore current patterns of production in Kazakhstan’s traditionally nomadic livestock sector. Experts see considerable potential for output expansion, and the government hopes to promote the sector as an alternative to revenues from hydrocarbons. Which production systems emerge will determine the use of the country’s vast pastoral resources, patterns of economic contribution from livestock and future greenhouse gas emissions. We focus on the beef sector, using original survey data and interviews from south-eastern Kazakhstan to compare rural households and farms by production strategy, generated using cluster analysis from data on livestock holdings, fodder provision and grazing. We examine in particular the relationships between farm size and the characteristics identified. We find that, rather than being specialised and intensive, larger farms tend to be highly diversified in terms of stock species, are more mobile and provide fewer supplements per head than smaller farms. Winter pastures appear to be a key resource associated with larger operations. Many large farms provide fodder mainly as low-quality roughage, although a subset with better access to cropland provide higher quality rations and fatten cattle before sale. Medium-sized farms lack either winter pasture bases or cropland for growing supplements, but proximity to markets enables some to compensate through fodder purchases. Inability to access government support, available only to large farms, hampers their expansion. Farmers’ professional background, distance from markets and environmental conditions are all associated with the production systems observed. In terms of policy, high transaction costs associated with leaseholds and lack of transferability between farmers impede access to land. Current pasture access mechanisms and institutions almost entirely exclude small farms and households. Changes in these systems, combined with infrastructure development, may bring economic, social and environmental benefits for the livestock sector and rural communities.

Seed productivity of tomato varieties of the Astrakhan selection

The tomato culture is the leader in terms of cultivation area and production volume among food products of plant origin. Fruits contain a variety of minerals, sugars, fats, vitamins.The goal of the study and study of economic characteristics: yield, marketability, average weight of fruits, weight of 1000 pieces. seeds and seed productivity of tomato varieties of two varieties, created by Astrakhan breeders and the use of the results obtained in planning seed production and the development of sale and purchase prices for varietal seeds to provide large farms, summer residents and owners of private farms with domestic seeds for the purpose of import substitution and suitable for various uses.Methods. The experiments were carried out in the fields of Precaspian agrarian federal scientific center of the Russian academy of sciences according to well-known methods. Studied 9 salad and 7 for mechanized harvesting varieties of tomato.Results. The article presents the results of studying the economic qualities and seed productivity of tomato varieties of two types, differing in shape, size, weight, fruit color and directions of use. The first group includes large-fruited salad varieties with non-cracking fruits, which are well stored and transported in brown maturity with an average fruit weight of 100-200 g or more. The second group – with plumshaped and elongated fruits, the average weight of which is 75-100 g, very dense, characterized by suitability for long-term transportation, and in terms of strength they are not inferior to foreign varieties and hybrids. The shape and weight of fruits of varieties of both groups are different, the yield and marketability of varieties is quite high, but the weight of 1000 seeds and seed productivity does not depend on these indicators, but is individual for each variety.

Typology, Structural Characterization and Sustainability of Integrated Broiler Farming System in Epirus, Greece

The aim of this study was the detailed characterization of the existing zootechnical and financial management applied in broiler poultry farms in the Region of Epirus, Greece. The current situation was captured through the formation of a typology on the structural characterization of broiler farming system. The variables were recorded based on data from a stratified random sample according to Neyman’s methodology of 110 poultry farms. In the typology, hierarchical cluster analysis was applied to identify differences between farms and to support most of this differentiation. Chebyshev distance was used to maximize the effect of the cluster elements distance, as well as Ward’s clustering method, which aims to achieve greater homogeneity within the clusters. Bonferroni multiple comparison tests were used to evaluate the differences. Four clusters of different farm types were identified from the hierarchical cluster analysis. In conclusion, the production system of broiler farms in Epirus is intensive, especially in large farms that have made significant investments in fixed capital and implement successful management. However, the poultry sector in Epirus has further margin for improvement in both its productivity and profitability.

One or many European models of agriculture? How heterogeneity influences income creation among farms in the European Union

Agricultural structures are quite heterogeneous across the European Union (EU), and it is likely that the underlying technology also differs across regions. In this article, we claim that the heterogeneity of agriculture across the EU affects the process of income creation (i.e. the relative importance of the factors of farm income differ for different agricultural models). A panel of farms representative for 125 regions reporting to the EU Farm Accountancy Data Network (FADN) during the period from 2007 to 2018 is used. In this article, those regions are grouped into three clusters. A system generalised method of moments (GMM) panel estimator is applied to each cluster. The results showed that total factor productivity (TFP), relative prices and agricultural subsidies make different contributions to farm net value added (FNVA). In particular, the income growth of farms in regions dominated by large farms seems to react more to marginal changes of the explanatory variables.

Specificity of transformational processes of management in the context of modern challenges for the system of agricultural relations

The paper substantiates the relevance of the considered issue, which is associated with the preservation of general contradictions in determining the essential characteristics of modern forms of economic management, their typology, and scenario forecasts for the development of small and large forms of management. The dualistic nature of the results of the transformation of the main forms of economic management in the system of the national economy was explained. The economic effects of transformation processes over two decades were analyzed and compared. It was revealed that: firstly, in the structure of production large farms prevail over the small ones; secondly, similar trends are observed in the dynamics of output volumes; thirdly, over the period under study, these trends remain stable. Scenario forecasts of the main trends in the further development of small and large forms of economic management were determined. The conservative scenario assumes further concentration and oligopolization in the agrarian sphere of the national economy. The baseline scenario assumes the preservation of the existing proportions of large and small forms of farming in the structure of agricultural production. The optimistic scenario assumes that the combination of the phenomenon of the impact of the global pandemic with the improvement of government support instruments for small businesses will increase the level of competitiveness in agricultural production.
