“…Agboola et al (2013) showed no significant effect of dietary enzyme supplementation on carcass and liver weight but reduced gizzard size of broilers. Some researchers reported that adding enzymes to diets did not affect relative weight of liver and gizzard of broiler chickens (Hassanein 2011;Emadinia et al 2014;Mohammadigheisar et al 2021). The present study also showed that BS4 enzyme supplementation did not significantly influence relative weight of liver and gizzard of broilers.…”

Supplementation of enzymes in feed is now commonly practiced to increase the nutrient availability of feed and the performance of poultry. A new enzyme called BS4 was produced by cultivating Eupenicilium javanicum. It is necessary to test the efficacy of this enzyme since the effectiveness of enzyme supplementation depends on many factors. An experiment was conducted to study the effect of dietary BS4 enzyme supplementation in improving the performance of broiler chickens. A number of 300 broilers DOC was distributed into 30 pens and reared until 35 d. Six experimental diets i.e., factorial of 2 (Standard diet, and low nutrient density diet) X 3 (Control, BS4 liquid enzyme, and BS4 powder enzyme) were formulated with 5 replications. The performance (feed intake, body weight, FCR, and survival rates) were observed during the starter (1-21 d) and whole (1-35 d) periods. At the end of the trial, measurements were also made on the carcass yield, abdominal fat, liver, and gizzard weights. Results showed that performances of broilers from 1-35 d were not significantly affected by interaction between nutrient density and enzyme supplement. The nutrient density also did not affect performances of broilers. However, dietary enzyme supplementation significantly reduced feed intake and improved FCR of broilers as compared to the control. Supplementation of BS4 in liquid or powder form, reduced feed intake by 3.6%. Supplementation of liquid and powder BS4 enzymes improved FCR by 6.4% and 8.9%, respectively, but no different effect between liquid and powder BS4 enzymes on performance of broilers. Nutrient density, enzyme supplementation, and interactions between the two factors did not significantly influence carcass yield, abdominal fat, liver, and gizzard relative weights of broilers.

“…The ME: protein ratio imbalances might not occur since the BS4 enzyme improved ME, protein, and amino acids digestibility of the feed (Pasaribu et al 2009;Sinurat et al 2014). Emadinia et al (2014) and Mohammadigheisar et al (2021) also reported similar results.…”

“…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.…”

“…The authors suggested that β-mannanase might have decreased digesta flow rate due to the greater hydrolysis of copra meal leading to improved nutrient utilization. It has also been demonstrated that β-mannanase improved digestibility of valine, methionine, and leucine in broiler chickens fed corn-SBM diet ( Mohammadigheisar et al, 2021 ).…”

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.

“…According to Abdollahi et al (2022), feed acidification improves the efficacy of exogenous enzymes by lowering the pH of the diet and digesta. There are recent studies on the positive effects of the separate supplementation of citric acid (Abd-Elsamee, 2020) and β-Mannanase (Mohammadigheisar et al, 2021). One unit of mannanase activity was defined as the amount of enzyme which generates 0.72 micrograms of reducing sugars per minute from a mannosecontaining substrate at pH 6.6 and a temperature of 104°F (Caldas et al, 2018).…”

The study was conducted to evaluate the effects of citric acid and mannanase feed supplementation on the growth performance of broiler chickens. Three hundred twenty day-old unsexed Cobb broiler chicks from a commercial hatchery plant were used in the study. The chicks were randomly assigned to four treatment groups following a completely randomized design. The following treatment groups were used: T1: Control, T2: 3% (w/w) Citric Acid supplementation, T3: 80 ppm β-Mannanase supplementation, and T4: 3% (w/w) Citric Acid and 80 ppm β-Mannanase supplementation. The supplementation of citric acid and mannanase significantly improves the growth performance of broiler chickens. Body weight and body weight gain were significantly higher (P<0.05) in the citric acid and β-mannanase combination group compared to all the treatment groups. The evaluation of feed intake revealed that T3 and T4 had significantly lower (P<0.05) feed intake than the other groups. The combination of citric acid and β-Mannanase also resulted in a significantly more efficient (P<0.05) feed conversion ratio. No mortality was observed during the experiment. It may be concluded that the supplementation of citric acid and β- mannanase resulted in a better performance in broilers.
