The scientific and practical rationale for the inclusion of enzyme preparations in the feed of young pigs

Abstract

Studies on growing young pigs for rearing and fattening using a mixture of enzyme preparations were carried out on animals aged 2 to 7 months in the dynamics of their growth and development. The animals receiving compound feed used in the economy served as control. The compound feed of the first experimental group was enriched with a mixture of additional enzyme preparations amylosubtilin G3x and cellolux-F, and the second experimental group – a mixture of amylosubtilin G3x and protosubtilin G3x. The use of a mixture of amylosubtilin G3x and cellolux-F increases the average daily growth by 13.6 %, reduces feed costs by 11.8 % compared to the control group’s pigs, a mixture of amylosubtilin G3x and protosubtilin G3x - an average daily increase of 8.7 %, a decrease in feed costs by 7.9 % compared to the control group’s pigs. The highest content of muscle tissue in the half-carcasses was observed in animals in the first experimental group (58.5 %) and in the second experimental group (58.17 %), which is higher in the control group by 0.93 and 0.6, respectively. The results of research in the technology of pork production reveal new possibilities of using a mixture of enzyme preparations.
