The present study was aimed to investigate the effects of supplemental β-mannanase on in vitro ileal disappearance (IVID) and in vitro total tract disappearance (IVTTD) of dry matter (DM) in barley, canola meal, copra meal, corn, corn distillers dried grains with solubles, cottonseed meal, palm kernel meal, soybean meal, and wheat for pigs. Feed ingredient samples were finely ground and divided into the control group and the treatment group. The samples of the control group were prepared to contain 990 g/kg test ingredient and 10 g/kg cornstarch, whereas the samples of the treatment group were prepared to contain 990 g/kg test ingredient and 10 g/kg β-mannanase product (8,000 units/kg in the mixed sample). A 2-step in vitro ileal digestion technique, which simulated the digestion and absorption processes in the stomach and small intestine, was used to determine the IVID of DM in test ingredients, whereas a 3-step in vitro ileal digestion technique, which additionally simulated the digestion process of the large intestine, was used to determine the IVTTD of DM in test ingredients. The in vitro digestion procedures were performed in triplicate for each sample. The addition of βmannanase increased (p = 0.003) the IVID of DM in wheat and tended to increase (p = 0.063) the IVID of DM in soybean meal. The IVTTD of DM in barley, cottonseed meal, and palm kernel meal was improved (p < 0.05) by the addition of β-mannanase. In conclusion, the digestibility of nutrients for pigs may be improved when β-mannanase is added into diets containing barley, cottonseed meal, palm kernel meal, soybean meal, or wheat.

“…There are many studies that assessed the effects of various exogenous enzyme products for swine diets, but the results of these experiments were different due to the differences between studies such as the enzymes, response criteria and ingredients compositions (Kwon et al 2015 ; Jones et al 2015 ; Mok et al 2015 ). These in vivo experiments require many expenses such as labor and money.…”

Two experiments were conducted to determine the effects of enzyme complex on in vitro dry matter (DM) digestibility for feed ingredients. The objective of experiment 1 was to screen feed ingredients that can be effective substrates for an enzyme complex, mainly consisted of β-pentosanase, β-glucanase and α-amylase, using in vitro digestibility methods. In experiment 1, the test ingredients were three grain sources (barley, corn and wheat) and six protein supplements (canola meal, copra expellers, cottonseed meal, distillers dried grains with solubles, palm kernel expellers and soybean meal). In vitro ileal and total tract digestibility (IVID and IVTTD, respectively) of DM for test ingredients were determined. In vitro digestibility methods consisted of two- or three-step procedure simulating in vivo digestion in the pig gastrointestinal tracts with or without enzyme complex. As the enzyme complex added, the IVID of DM for corn and wheat increased (p < 0.05) by 5.0 and 2.6 percentage unit, respectively. The IVTTD of DM for corn increased (p < 0.05) by 3.1 percentage unit with enzyme complex addition. As the effect of enzyme complex was the greatest in corn digestibility, corn grains were selected to determine the in vitro digestibility of the fractions (starch, germ, hull and gluten) that maximally respond to the enzyme complex in experiment 2. The IVID of DM for corn starch, germ and hull increased (p < 0.05) by 16.0, 2.8 and 1.2 percentage unit, respectively. The IVTTD of DM for corn starch and hull also increased (p < 0.05) by 8.6 and 0.9 percentage unit, respectively, with enzyme complex addition. In conclusion, the enzyme complex increases in vitro DM digestibility of corn and wheat, and the digestibility increments of corn are mainly attributed to the increased digestibility of corn starch.

“…Supplementing β-mannanase in corn-SBM diets with corn DDGS or palm kernel meal or corn DDGS and palm kernel meal improved ATTD of gross energy in growing-finishing pigs ( Kim et al, 2013 , 2017b ; Jeon et al, 2019 ). It has been shown that β-mannanase improved nutrient digestibility in pigs fed corn-SBM diets containing up to 12% palm kernel meal ( Mok et al, 2013 , 2015 ; Jang et al, 2020b ). However, supplemental β-mannanase did not improve energy and nutrient digestibility in pigs fed corn-SBM diets containing more than 15% palm kernel meal ( Kwon and Kim, 2015 ; Jang et al, 2020b ).…”

This review will give a brief description of β-mannans, abundance in feedstuffs, utility of supplemental feed β-mannanase and subsequent animal responses. Soybean products and co-products of processing palm, coconut and guar seeds are the major sources of β-mannans in poultry and livestock feed. β-mannans are linear polymers of mannose residues linked by β-1,4 glycosidic bonds and their ingestion elicit undesirable and metabolically costly responses. Web of Science was searched to retrieve published studies for meta-analyses of the impact of supplemental β-mannanase on performance and digestibility in pigs and poultry. The mean difference (MD) between ß-mannanase and control on average daily gain (ADG, g/d) was +0.23 (P=0.013; 95% CI 0.05; 0.41), +10.8 g/d (P=0.0005; 95% CI of 6.6; 15.0 g/day) and +20.68 (P<0.000; 95% CI of 17.15; 24.20 g/day) for broiler chickens, nursery pigs and grow-finish pigs, respectively. The MD on β-mannanase improvement on FCR was -0.02 (P<0.0001) with 95% CI (-0.03; -0.02) suggesting a 2-to-3-point FCR improvement in broiler chickens. ß-mannanase improvement on gain to feed (G:F) was +13.8 g/kg (P=0.027; 2.1; 25.4 g/kg) and +8.77 g/kg (6.32; 11.23 g/kg) in nursery and grow-finish pigs, respectively. β-mannanase improved AMEn by 47 kcal/kg (P=0.0004) with 95% CI (28.8; 65.7 kcal/kg) in broiler chickens. The improvement of gross energy digestibility in pigs was 1.08 percentage unit with 95% CI (0.90; 1.26) translating to the release of between 30.6 and 42.8 kcal/kg of digestible energy. Although data was limited, β-mannanase improved egg production but had no impact on egg quality in laying hens. Turkeys may be more adversely affected by ß-mannans because of the high protein/ amino acids requirements necessitating higher dietary inclusion of soybean meal. However, growth performance and feed efficiency responses of turkeys fed diets supplemented with β-mannanase was variable. In summary, ß-mannanase supplementation improved performance linked to energy and nutrient utilization. However, the magnitude of response was variable within and between species indicating further application refinement is warranted to achieve consistent efficacy, including an improved understanding of the functional contribution of β-mannans hydrolysis products.
