THE EFFECTIVENESS OF THE USE OF NATURAL ZEOLITES IN THE FEEDING OF STORE PIGS

Abstract

The purpose-oriented use of a silicon-containing zeolite as a preventive and therapeutic food additive when feeding animals and birds makes it possible to increase their productivity. Four mixed fodder formulas were developed to carry out the experiment: one without zeolite tripoli and three with 3, 4, 5 % of this additive. Based on scientific and economic studies, the experiment has shown that the optimum additive dose of this preparation is 3% of the feed weight. In addition, it was found that the absolute growth increased by 13.5 % in the second group, and by 7.2 % in the third group. In the fourth group, it decreased by 4.41 % compared to the control group. Studies have shown that the addition of silicon-containing zeolite in the second and third experimental groups did not affect the food intake of the experimental animals. In contrast, in the fourth experimental group, an appetite decrease was observed. Feed consumption per unit live weight in the second, third and fourth experimental groups decreased by 12.1%, 6.7% and 0.3%.
