The current condition of breeding in animal farming in Russia and on the regional example the Saratov area was researched. The indicators of the development of pig breeding, meat and dairy cattle breeding are analyzed. Data on livestock scoring and the specific share of various breeds of pigs and cattle in households of all categories are presented. The main problems of the development of stock breeding were identified, among which: the destruction of a unified system of breeding work, the lack of specialized education in the regions, reduction of specialized research institutions, reduction in the number of breeding enterprises, etc. The organizational and economic structure of the livestock cluster, consisting of a production core (agricultural, processing and marketing enterprises) and serving satellites (supplying organizations of scientific, technical, educational, financial and credit and insurance sectors) is proposed. The need for the creation of regional reception centers for primary meat processing and the Center for Cluster Development was also identified. And the creation of a single Selection and Hybrid Center in the regions will allow to restore and systematize the breeding work in the agricultural enterprises participating in the cluster. The implementation of proposals for the organization of breeding in the regions on the basis of livestock clusters will solve a number of organizational and economic problems of increasing the competitiveness of the main animal breeds and the efficiency of livestock production.
and TEM analyses have been used to study the state of the surface layer and the evolution of the defect substructure of Hadfield specimens as a function of depth below the worn surface. Gradient structure is shown to form in the examined steel type during dry sliding wear. The defect density in the structure and its microhardness are found to reduce with depth below the worn surface.
