Effects of xylanase supplementation on growth performance, digestibility, fecal gas emission, and meat quality in growing-finishing pigs

Abstract

A total of 144 crossbred pigs [(Landrace × Yorkshire) × Duroc] with an initial body weight (BW) of 25.7 ± 2.3 kg were used in a 16-wk study to evaluate the effects of xylanase supplementation in growing-finishing pigs. Treatments were as follows: control diet (CON); low-energy diet (LX) + 0.01% xylanase; and alternative diet (AX) + 0.01% xylanase. From weeks 0 to 6, pigs in the AX treatment had greater (P < 0.05) average daily feed intake (ADFI) than those in the CON treatment. On the sixth week, higher (P < 0.05) apparent total tract digestibility (ATTD) of energy was observed in the AX treatment compared with the CON treatment. Pigs fed the AX diet had the lowest (P < 0.05) ATTD of energy among all of the treatments on week 12. At the end of the experiment, the ATTD of dry matter (DM) of pigs in the LX treatment was higher (P < 0.05) than those in the AX and CON treatments. The redness values in the LX and AX treatments were higher (P < 0.05) than that in the CON treatment. In conclusion, our results indicated that dietary inclusion of 0.01% xylanase supplement could improve ADFI during weeks 0-6, ATTD of DM at week 16 and energy at weeks 6 and 12, and the redness color of meat in growing-finishing pigs.

Investigation of xylanase, diet formulation method for energy, and choice of digestibility index marker on nutrient and energy utilization for broiler chickens and pigs

“…Benefical effects of inclusion of exogenous xylanase have been reported in wheat-based diets in both poultry (Adeola and Bedford, 2004;Olukosi et al, 2007) and pigs (Barrera et al, 2004;Vahjen et al, 2007) due to the high concentration of nonstarch polysaccharide (NSP) in wheat. Xylanase has also been evaluated in CSBM diets in both chickens and pigs (Stefanello et al, 2016;Cho et al, 2017). Similar to the results of several previous studies conducted in broiler chickens (Nian et al, 2011), no effect of exogenous xylanase on growth performance in broiler chickens was observed in the current study.…”

“…Xylanase is one of the exogenous enzymes that have been widely used for commercial feeds in poultry and swine industry (Adeola and Cowieson, 2011). The evaluation of xylanase has been conducted in 1 wheat-based diets (Yin et al, 2000b;Cowieson and Masey O'Neill, 2013) and corn-soybean meal-based (CSBM) diets (Stefanello et al, 2016;Cho et al, 2017) in both chickens and pigs. Negative control diets formulated to contain less energy than positive control (PC) diets are commonly used to evaluate the efficacy of xylanase supplement (Liu and Fowler, 2017).…”
