Abstract

This study evaluated the influence of enzyme mixture supplementation on the growth performance, nutrient digestibility, and fecal score of growing pigs. A total of 72 pigs with an initial body weight of 20.23 ± 1.46 kg were randomly assigned to two treatments consisting of a basal diet and the basal diet supplemented with 0.5% enzyme mixture. During a 19-day trial, no significant difference was observed in the body weight (BW) and average daily feed intake (ADFI) of the pigs. However, a gradual increase in the average daily gain (ADG) was observed during the period from day 14 to day 19 and the overall period in pigs fed a diet supplemented with the 0.5% enzyme mixture (p < 0.10) as compared to the pigs that were fed the control diet. From days 4 to 14 and in the overall experiment, a gradual increase in the feed conversion ratio (FCR) (p < 0.10) was observed with the inclusion of 0.5% enzyme mixture supplementation. The nutrient digestibility of dry matter (DM), nitrogen (N), and energy were not affected by enzyme mixture supplementation. In addition, dietary supplementation with the enzyme mixture had no significant effects on the fecal score of growing pigs. In summary, supplementation with the enzyme mixture had beneficial effects on the ADG performance but failed to have a significant effect on growth performance (BW), nutrient digestibility, and fecal score.
