Simple Summary  Phytate is the primary storage form of phosphorus in grain-based feedstuffs, which can reduce the utilization of the phosphorus, calcium, and other minerals. Additionally, non-starch polysaccha-rides can increase digesta viscosity and thus decrease the nutrient digestion and utilization. The current study has evaluated the effects of a next-generation multicarbohydrase and phytase com-plex on the growth performance, apparent total tract digestibility of nutrients, carcass traits, and meat quality in growing-finishing pigs fed a corn-wheat-soybean meal-based diet. The results showed that dietary supplementation of the multicarbohydrase and phytase complex improved the growth performance and nutrient digestibility but had little effect on carcass traits and meat quality in growing-finishing pigs fed a corn-soybean meal-wheat-based diet. These findings indi-cate that the multicarbohydrase and phytase complex could be used as a promising enzymes product to mitigate the negative effects of phytate and non-starch polysaccharides.    Abstract  The objective of this study was to evaluate the efficacy of supplementing a corn-wheat-soybean meal-based diet with a multicarbohydrase and phytase complex (MCPC) on growth performance, apparent total tract digestibility (ATTD) of nutrients, carcass traits, and meat quality in growing-finishing pigs. A total of 300 pigs (Duroc × Large White × Landrace; body weight = 25.3 ± 0.7 kg) were randomly allotted to three groups with 10 replicates of 10 pigs each. Pigs from three groups were fed positive control (PC) or negative control (NC), without or with MCPC diets, respectively. The MCPC supplied at least 1800, 1244, 6600, and 1000 units of xylanase, β-glucanase, α-arabinofuranosidase, and phytase per kilogram of diet, respectively. The NC diet was the PC diet but reduced in net energy (NE), digestible amino acids (dig. AA), digestible P (dig. P), and Ca by 74 kcal/kg, 7.0%, 0.134, and 0.119 percentage points, respectively. The diets were fed in 4 growth phases based on body weight (BW): phase 1: 25–50 kg, phase 2: 50–75 kg, phase 3: 75–100 kg, and phase 4: 100–135 kg. Compared to the PC, the NC diet decreased ( p  < 0.05) body weight gain, feed intake, and(or) feed to gain ratio during the growing/finishing phases 1, 2, 3, and 4. It also reduced ( p  < 0.05) the ATTD of crude protein, crude fat, P, and Ca of pigs. MCPC supplementation improved ( p  < 0.05) the body weight gain, feed intake, and(or) feed to gain ratio in phases 2, 3, and 4 and the ATTD of crude protein, crude fat, ash, P, and Ca for the NC diet. Additionally, dietary treatment had no effects on carcass traits and meat quality with the exception that the loin eye area in the NC plus MCPC diet was higher ( p  < 0.05) than the NC diet. In conclusion, the addition of MCPC to a corn-soybean meal-wheat-based diet reduced in energy and nutrients improved the growth performance and nutrient digestibility but had little effect on carcass traits and meat quality in growing-finishing pigs.
