Influence of biologically active substances in the diet on the productive and reproductive traits of pigs

Abstract

The introduction of biologically active and mineral compounds into the diet of pigs has a benefi cial eff ect on the course of metabolic processes in the body of animals and makes it possible to have a targeted eff ect on the productive and reproductive traits of animals, as well as increasing the profi tability of pig farming. The purpose of the work was to study the infl uence of biologically active substances in the diet on the productive and reproductive traits of pigs. The conducted studies are devoted to the study of the effectiveness of the use of folic acid and trace element salts in the diet of pregnant sows on their reproductive traits, as well as the growth, development and meat productivity of the young pigs. The feeding diet of the animals of the experimental groups was identical, however, the sows of the 2nd, 3rd and 4th experimental groups in addition to the main diet received biologically active additives folic acid and trace element salts from the fi rst to the last day of pregnancy. It was found that in the 1st control group based on one sow a total of 11,0 piglets were obtained, whereas in the 2nd experimental group there was by 1 piglet more, in the 3rd experimental group by 1,5 heads more, and in the 4th experimental by 2,2 heads more. The use of folic acid and trace element salts in the feeding of sows also had a positive effect on the live weight, absolute and average daily live weight gains of the young pigs. Moreover, the best results were obtained in the 4th experimental group, where sows received folic acid and trace element salts together. So, it is economically justified to use biologically active additives based on folic acid and trace element salts in the diet of pigs, which significantly reduces expenditures of feed per unit of production.
