“…Rainbird et al (1984) noticed that supplementing β-mannanase resulted in a decrease in glucose and water absorption in pigs. Present findings are consistent with data reported by Yoon et al (2010) and Kim et al (2013) who observed increase in blood glucose concentrations but no effects on the total cholesterol and triacylglycerides in pigs fed diets supplemented with β-mannanase. In contrast to the report by Yoon et al (2010), Kim et al (2013) and the present results, Jo et al (2012) reported that dietary inclusion of enzyme blend containing β-mannanase to the corn-SBMbased simple diet or complex diet had no effects on blood glucose concentrations.…”

“…The lack of an effect on ADFI of β-mannanase in the present experiments is in agreement with previous experiments (Jacela et al, 2010;Yoon et al, 2010). The improved growth performance of growing pigs fed diet supplemented with β-mannanase found in these trials might be partly due to enhanced digestibility of DM, GE and β-mannan, which was in agreement with Kim et al (2013) who reported higher final BW, digestibility of DM and GE in β-mannanase supplemented diet. High levels of NSP in pig diets can cause an increase in digesta viscosity, preventing interaction between substrate and digestive enzymes and, hence, reducing the nutrient digestibility (O'Connell et al, 2005;Passos et al, 2015).…”

“…1 is in good agreement with data reported by Yoon et al (2010) and Kim et al (2013) who observed improvement in ADG of pigs fed diets supplemented with increasing levels of β-mannanase. The main reason that could have contributed to the influence of β-mannanase enzyme may be due to the mannan hydrolysis which can increase permeability of the cell walls and cut the long-chain polysaccharides to improve the digestibility of nutrients.…”

“…The lower nutrient utilization and growth performance refers to the lack of enzymes in pig digestive tract to break β-1, 4-mannosyl bond and α-1, 6-galactosyl bonds (Veum and Odle, 2001). Previous studies have reported that dietary supplementation of β-mannanase or enzyme complex with β-mannanase can improve the growth performance and nutrient digestibility of growing pigs by removing the negative effect of mannan (Pettey et al, 2002;Ao et al, 2011;Jo et al, 2012;Kim et al, 2013).…”

The exogenous enzymes are less consistent in their effects as their beneficial effects depend upon the types and level non-starch polysaccharides (NSP) present in the diets. Therefore, exogenous enzymes should be selected on the basis of types and amount of the NSP in the pig diets. The objectives of the present experiments were to investigate the effects of dietary level of mannan and β-mannanase supplementation on growth performance, apparent total tract digestibility (ATTD) of energy and nutrients, and blood metabolites of growing pigs. In Exp. 1, 96 barrows were randomly allotted to four treatments on the basis of BW. There were four replicates in each treatment with six pigs per replicate. The dietary treatments were a corn-soybean meal (SBM)-based control diet and three other diets consisted of the control diet supplemented with 400, 800 or 1600 U of β-mannanase/kg diet. The final BW, average daily gain (ADG) and blood glucose increased (linear, P < 0.05) with increasing concentrations of dietary β-mannanase. The ATTD of dry matter (DM), gross energy (GE) and β-mannan was higher (linear, P < 0.05) with increase in dietary β-mannanase concentrations. In Exp. 2, 288 barrows were allotted to six treatments in a 2 × 3 factorial arrangement of mannan level (high v. low) and addition of β-mannanase (0, 400 or 800 U/kg diet). There were four replicates in each treatment with 12 pigs/replicate. Pigs were fed corn-SBM-based low-mannan diet (6.1 g/kg) or high-mannan (25.2 g/kg) diet in which corn and SBM were partially replaced with 50 g/kg diet palm kernel meal. All diets were fed in meal form for 42 days. Pigs fed diets supplemented with β-mannanase had greater ( P < 0.05) final BW, ADG, feed to gain (F : G), the ATTD of DM, GE, and β-mannan and blood glucose concentration compared with pigs fed diets without β-mannanase. In addition, the final BW, ADG, F : G and the ATTD of GE and β-mannan were reduced ( P < 0.05) in low mannan level. The dietary level of mannan and the β-mannanase supplementation had no effects ( P > 0.05) on the concentrations of blood total cholesterol, triacylglycerides and blood urea nitrogen. These results indicate that supplementation of β-mannanase to low-or high-mannan diets have potential to improve the performance of growing pigs. In addition, palm kernel meal may partially replace corn and SBM without reducing pig performance if β-mannanase is added to diet.Keywords: blood metabolites, growing pigs, performance, mannan, β-mannanase ImplicationsThe β-mannan accounts for 15% to 35 % (soy-based to palm-based) of total non-starch polysaccharides content of the pig diets, β-galactomannan, is a polysaccharide with repeating units of mannose, with galactose or glucose, or both, often found attached to the β-mannan. Pig digestive tract lacks the enzymes targeting β-1, 4-mannosyl bond and α-1, 6-galactosyl bonds, which limits the nutrient utilization and growth performance. These results indicate that β-mannanase have potential to improve the performance of growing pigs, and palm kernel meal m...

“…Down-regulation of this protein was observed in the LM of NSPEsupplemented pigs, whereas the serum level of triglyceride was not different between the two groups. This behavior is consistent with previous research which showed that supplementation with NSPEs had no effect on serum level of total triglyceride (Kim et al, 2013).…”

Non-starch polysaccharide enzymes (NSPEs) have long been used in the feed production of monogastric animals to degrade non-starch polysaccharide to oligosaccharides and promote growth performance. However, few studies have been conducted on the effect of such enzymes on skeletal muscle in monogastric animals. To elucidate the mechanism of the effect of NSPEs on skeletal muscle, an isobaric tag for relative and absolute quantification (iTRAQ) for differential proteomic quantitation was applied to investigate alterations in the proteome in the longissimus muscle (LM) of growing pigs after a 50-d period of supplementation with 0.6% NSPEs in the diet. A total of 51 proteins were found to be differentially expressed in the LM between a control group and the NSPE group. Functional analysis of the differentially expressed protein species showed an increased abundance of proteins related to energy production, protein synthesis, muscular differentiation, immunity, oxidation resistance and detoxification, and a decreased abundance of proteins related to inflammation in the LM of the pigs fed NSPEs. These findings have important implications for understanding the mechanisms whereby dietary supplementation with NSPEs enzymes can promote growth performance and improve muscular metabolism in growing pigs.
