Abstract

The purpose of the study was to study the effectiveness of using ultrafine copper particles as part of an enzyme-containing diet for broiler chickens. The research results indicate that each of the components of the proposed strategy influenced a certain functional system of the body with a subsequent range of adaptive changes, which ultimately led to a change in the efficiency of broiler rearing. In particular, it was found that the proposed substances have a growth-stimulating effect to varying degrees. Feeding the enzyme was accompanied by a maximum increase in the live weight of the experimental birds (13.75%), but in this case the maximum palatability of the feed was noted (a difference with the control of 6.7%). The strategy of complex introduction of enzyme and ultrafine copper was more effective and was accompanied by a decrease in feed costs in comparison with the group of introduction of only enzyme, with a difference in live weight with the control of 13.68%.
