EFFECT OF THE ENZYME “CELOZYM” ON NUTRIENT DIGESTIBILITY AND FEED UTILIZATION EFFICIENCY IN GROWING PIGS

The article presents the results of studies on the effect of the enzyme preparation «Celozym» on nutrient digestibility and feed utilization efficiency in growing pigs during the fattening period. The research was conducted under conditions of a production and scientific experiment with the formation of one control group and three experimental groups that received complete feed mixtures with different levels of enzyme supplementation. Productive performance indicators, feed unit consumption per 1 kg of live weight gain, feed conversion, as well as digestibility coefficients of the main nutrients were evaluated based on balance trials. It was established that the inclusion of «Celozym» in pig diets increased fiber digestibility by 13.3–25.0% and protein digestibility from 72.5 to 75.5% compared with the control group (P < 0.05). Improved digestibility was accompanied by a reduction in feed unit consumption per unit of gain by 7.2–14.0% and an increase in feed conversion efficiency by 10.3–17.2%. The most pronounced effect was observed in the group receiving the highest level of enzyme supplementation. The obtained results indicate the feasibility of using the enzyme preparation «Celozym» in diets of fattening pigs to enhance the biological availability of nutrients and improve feed utilization.
