| Popis: | The intensification of the pig industry requires the breeding of highly productive young animals capable of providing high-growth energy under good conditions of maintenance and full feeding. Full feeding of suckling piglets in most farms of Ukraine is provided by pre-starter compound feeds of imported production, which leads to an increase in the cost price of pork. In addition, the traditional sources of trace elements in these compound feeds are mineral salts in the form of sulfate and chloride compounds, the bioavailability of which is 12–35 %, which leads to environmental pollution with heavy metals, and the crystallized water contained in sulfate molecules in the premixes destroys vitamins and other biologically active substances. The degree of assimilation of trace elements increases with the use of feed additives with trace elements of organic origin. Representatives of such feed additives are mixed ligand complexes of trace elements (chelates). Taking into account the fact that suckling piglets need Ferrum addition to mother's milk and a sufficient amount of Cuprum on the 4–5th day of life since Cuprum catalyzes the incorporation of Ferrum into the heme structure and is an indispensable activator of hemoglobin synthesis and a stimulator of erythrocyte maturation, the study of the action of this element in the composition of a mixed ligand of the complex in the pre-starter compound feed is relevant. In addition, the study of the economic and economic significance of the use of the mixed ligand complex of Cuprum in the feeding of suckling piglets, the establishment of optimal norms of this supplement taking into account the breed and parent age, has an important scientific and practical significance. The domestic and foreign experience of effective pig farming shows that the realization of the hereditary qualities of modern high-performance pig breeds and obtaining ecologically clean products is possible only under the condition of the development and implementation of perfect technologies for the production of pig farming products, which must be consistent with the biological needs of animals. |
