Summary

Structure of the thesis: The PhD thesis is presented on 129 pages of basic computer text. It consists of an introduction, a literature review, research material and methodology, results of own research, discussions of the obtained results, practical conclusions and suggestions, bibliographic list and the applications. It contains 33 tables, 51 figures and 17 applications.

The bibliography includes 272 sources, of which 29 are in a foreign language. The purpose of the study: to justify scientifically and practically justify the use of the complex enterosorbent additives “Micofix® Plus” and “Vitacorm REO-M”, to study their properties and influence on the organism and on the reproductive qualities of breeding pigs.

Scientific novelty and originality: for the first time, as applied to the conditions of the pig-breeding industry of the Republic of Moldova, the expediency of the utilization of the enterosorbent additives “Micofix® Plus” and “Vitacorm REO-M” (which were confirmed by the Moldavian patents for invention “Piglet growth processes”, No. 849 of 31st July 2015, and “Piglet feeding processes”, No. 1044 of 31st January 2017), when breeding piglets in order to increase their economic and biological indices and profitability, has been experimentally proved and theoretically justified. Solved scientific problem issue: was to develop optimal conditions for the effective use of new enterosorbent additives in swine-breeding, which led to a decrease in contamination of feed by toxins, which, in its turn, increased the productivity of young pigs and reduced feed costs.

The applicative value of the work: there it has been identified the ability to increase productive qualities and to improve the metabolism of young pigs when the enterosorbent additives “Micofix® Plus” and “Vitacorm REO-M” were included in the fodder composition. The use of these enterosorbents contributed to the increase augmentation in live weight and to the improvement of the physiological and biochemical state of young pigs.

The introduction practical use of the obtained data into production allows for an increase into grow the efficiency of pig production and reduction in the feed consumption per production unit. In order to have targeted amelioration of the direct product quality and productivity in pig production, practical recommendations have been developed on optimal levels of feed additive intake in compound feed of breeding pigs.

The implementation of scientific results:the research materials were used in the development of guidelines on the feeding of farm animals and on the feed preparation technology. The data obtained as a result of the research led to the taking out of two patents and the development of some practical recommendations.
