“…Moreover supplemented βmannanase to diet that contains antinutritional galactomannan decreased intestinal viscosity and improving feed conversion (Dhawan and Kaur 2007). This improvement in agreement with Caldas, et al (2018) and may be due to βmannanase hydrolyzed galactomannan into to mannose and galactose (El-Masry, et al, 2017 andKurakake, et al, 2006). Mannose has ability to competitive exclusion where it competes with glycoprotein in intestine and prevents colonization and salmonella from attachment with intestinal sites (Berge and Wierup, 2012).…”

This experiment was carried out to evaluate the effect of dietary guar meal levels with or without β-mannanase on layer performance. One hundred and sixty eight 22-week-old Golden Montazah pullets divided randomly into seven treatment groups each group had 24 pullets divided into three replicates with 8 pullets per each. The 1 st group fed on corn-soybean meal diet and served as control group. The 2 nd , 4 th and 6 th groups fed on diets contain 5%, 10% and 15% guar meal respectively without βmannanase. The 3 rd , 5 th and 7 th groups fed on diets contain 5%, 10% and 15% guar meal with 250 mg/kg β-mannanase respectively. The experiment was extended for three months to estimate production performance. At the end of the experiment egg quality was assayed and slaughter assay was conducted. The following results were obtained:-Adding 10% guar meal had no harmful effects on egg production performance, however increasing guar meal up to 15% retarded clearly egg production performance compared with control. Remarkable improvements in production performance were observed when β-mannanase supplemented to guar diets. Significant improvement in shell weight percent and shell thickness were observed by increasing guar level up to 15% with or without β-mannanase compared with control treatment, in contrast significant decrease was observed in albumen weight. Neither guar meal levels nor β-mannanase supplementation influenced liver, gizzard, heart and spleen weight percent. All guar meal treatments with or without β-mannanase recorded significantly (P≤ 0.05) lower abdominal fat percent than control treatment. Increasing guar meal than 5% increased significantly (P≤ 0.05) thymus weight percent but supplemented β-mannanase decreased significantly (P≤ 0.05) thymus weight percent. The best relative economic efficiency value recorded for diet that contains 5% guar meal with β-mannanase.

“…Specifically, β-mannanase improved AME by 143 kcal/kg concomitant with 3% improvement on growth and FCR. β-Mannanase supplementation has been demonstrated to have positive effects on performance and nutrient digestibility in poultry fed corn-SBM-based diets as well as diets containing guar meal, copra meal, and other β-mannan-containing components ( Daskiran et al, 2004 ; Jackson et al, 2004 ; Ferreira et al, 2016 ; Balasubramanian et al, 2018 ; Caldas et al, 2018 ; Mohammadigheisar et al, 2021 ). Some of these positive effects have been ascribed to mechanisms that are different compared to the modes of action of other NSP carbohydrases such as reducing FIIR.…”

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.

“…The main effects of inclusion of enzyme also had a significant increase in apparent ileal digestibility of a nonessential amino acid, serine, in laying hens ( Table 7 ). In this current study with layers and in Caldas et al (2018) with broilers, partial improvement of apparent ileal digestibility of essential amino acids were observed depending on different levels β-mannanase enzyme being added. Higher ileal amino acid digestibility is observed for broilers with inclusion of β-mannanase, possibly due to broiler diets containing higher levels of CP with more SBM in diet compared to layer diets ( Sundu et al, 2006 ).…”

Effects of dietary protein, energy and β-mannanase on laying performance, egg quality, and ileal amino acid digestibility in laying hens

β-mannan is a nonstarch polysaccharide found in hulled and dehulled soybeans that can survive drying-toasting phase of processing soybeans and have antinutritive effects in poultry. β-mannanase is an active enzyme (endohydrolase) that can hydrolyze β-mannan to reduce its antinutritional effects. Two experiments were conducted to evaluate the effects of β-mannanase supplementation in low energy/protein diets on egg production, egg quality, and apparent ileal digestibility of the dry matter ( DM ), crude protein ( CP ), and amino acids in 21-week-old Single Comb White Leghorn hens (Hy-Line W-36). A total of 192 hens (8 replicates of 6 hens per treatment) for a production study (Exp. 1) and a total of 64 hens (8 replicates of 2 hens per treatment) for a digestibility study (Exp. 2) were randomly allocated to 4 experimental treatments in a 2 × 2 factorial arrangement. Four dietary treatments were control ( CS ) based on corn and 44% CP soybean meal (ME: 2,850 kcal/kg CP: 18.5%) and CS-low energy/protein ( CSL ) (ME: 2,750 kcal/kg CP: 17.5%), with or without 0.05% β-mannanase enzyme. Hens were fed the experimental diets for 14 d for the digestibility study and 8 wk for the production study. Hen-day egg production ( HDEP ), weekly feed intake, FCR, and biweekly egg quality parameters were measured. Significant interaction on feed intake ( P < 0.01) was observed between energy/protein and enzyme. At 3, 6 and 8 wk, the feed intake and FCR of CSL with enzyme were significantly lower than those of CSL without enzymes. The main effects indicated that birds fed diets without inclusion of β-mannanase had higher feed intake than those fed diets with enzymes at 4, 7, and 8 wk. The inclusion of β-mannanase significantly increased ( P < 0.05) HDEP at 2, 3, 5, and 7 wk. However, there was no significant effect of nutrient density or enzyme supplementation on egg quality parameters. The digestibility study showed that the inclusion of β-mannanase significantly improved ( P < 0.01) apparent ileal digestibility of lysine, histidine and tryptophan in the diet. The results of these experiments indicate that supplementation of β-mannanase could reduce the feed intake and FCR and improve HDEP and apparent ileal digestibility of key amino acids in corn/soy diets fed to laying hens.
