“…Specifically, b-mannanase increased abundance of gut-health-associated microbiota (e.g., Lactobacillus, Ruminococcaceae, and Akkermansia) and reduced bacteria associated with poor feed efficiency (Bortoluzzi et al, 2019). Further research showed that broiler chickens fed 0.035% of MOS extracted from copra meal increased lactic acid bacteria (Putri et al, 2017).…”

The provision of adequate and balanced nutrients is critical for efficient and profitable animal protein production. However, non-nutritive components in feedstuffs can elicit responses that can negatively impact nutrient utilization efficiency. For example, dietary β-mannans are recognizable by cell surface mannose receptors are pivotal for diverse cellular functions. This review will evaluate the physiological implications of dietary native β-mannans, the utility of supplemental feed β-mannanase in hydrolyzing β-mannans, and subsequent metabolic responses. Dietary native β-mannans have been implicated in inadvertent stimulation of immune response through a phenomenon called the feed-induced immune response (FIIR), that has been associated with intestinal inflammation and depression in animal performance. Supplemental β-mannanase blunted the FIIR by hydrolyzing native β-mannans to smaller fragments with a reduced ability to stimulate the innate immune system as indicated by the modulation of oxidative stress, mucosal permeability, and blood concentration of acute phase proteins and immunoglobulins in broilers and piglet models. Moreover, β-mannanase hydrolysis of native β-mannans to mannooligosaccharides (MOS) impacted gastrointestinal microbial ecology. Indeed, β-mannanase-derived MOS reduced the concentration of pathogenic bacteria such as Escherichia coli and Salmonella and increased the production of short-chain fatty acids in gastrointestinal tracts of various animal models. Consequently, by hydrolyzing native β-mannans, supplemental β-mannanase may have nutritional, metabolic, and microbial ecology benefits. In summary, integrating multi-functional feed additives such as β-mannanase into feeding programs for monogastric animals will be critical for efficient and sustainable animal protein production in the context of evolving challenges such as the mandated elimination of use of antibiotics for growth promotion.

“…Improved feed intake and protein digestibility on the 150 g/kg ECM diet could be reasons for higher WBC count in the present study. The beneficial effect of mannan fibre on gut health is well reported (Sundu et al, 2012;Putri et al, 2017). Putri et al (2017) observed higher leukocyte counts in broilers fed a 0.35g ECM mannan oligosaccharides per kg diet when compared to control and antibiotic supplemented diets.…”

This study analyzes the effect of different levels of expeller copra meal (ECM) in animal protein-based diets with enzyme on the haematology, carcass and fatty acid composition of broilers. One hundred and sixty 20 days old Cobb broilers were assigned 8 different diets, 2 of them being controls and 6 others containing ECM at 150, 300 and 450 g/ kg, with or without enzymes. Four replicate cages of 5 birds each were fed the diets in a completely randomized design. Higher white blood cell (WBC) counts were obtained in chickens fed the control and 150 g/kg ECM with enzyme (p<0.05) diets. Meat saturated fatty acids (SFA) content increased on the 150 g/kg diet and later decreased above 300 g/kg without enzyme (p<0.05). Monounsaturated fatty acid (MUFA) content was reduced with the inclusion of increasing ECM levels (p<0.05). No interaction effect on polyunsaturated fatty acids (PUFA) was found. Main effects observed were MUFA and PUFA decrease with the inclusion of ECM in the diet (p<0.05). Saturated fatty acid (SFA) content was found to increase on the 150 g ECM/kg diet and later to reduce with increasing ECM levels (p<0.05). Enzyme supplementation reduced SFA and MUFA content (p<0.05) but had no effect on PUFA (p>0.05). In conclusion, inclusion of ECM up to 300 g/kg in corn-animal protein diets has no adverse effects on most broiler haematological variables, but meat fatty acid composition may be altered. More research into basal diet composition, enzyme source and concentration is recommended.

“…According to Nabizadeh (2012), addition of inulin in the diet raised the amount of Bifidobacteria in broiler chickens significantly. Putri et al (2017) said that MOS prebiotic triggered the number of lactid acid bacteria in broiler during 28 days old. Perdinan et al (2019) also stated that porang glucomannan increased lactid acid bacteria in broiler chickens.…”

Glucomannan is consisted of D-glucose and D-mannose with β-1.4 linkages. Poultry had no enzyme to digest β linkage so that porang (Amorphophallus onchophyllus) glucomannan could be a prebiotic candidate. The study purposed to determine the effect of porang glucomannan on caecum bacterial composition (similarity, diversity, grouping of bacteria) using Terminal Restriction Fragment Length Polymorphisms method and performance (body weight gain, feed intake, feed conversion ratio) of broiler chickens. One hundred and eighty unsexed day old chicks (DOC) were divided into 6 treat-ments and 3 replicates (10 birds each) using completely randomized design (CRD). The treatments were P0 (basal feed), P1 (basal feed + 0.05% porang glucomannan), P2 (basal feed + 0.1% porang glu-comannan), P3 (basal feed + 0.15% porang glucomannan), KJ (basal feed + 0.1% commercial konjac glucomannan), and KM (commercial feed). The results showed that caecal bacterial composition of porang glucomannan treatment had similarity with konjac glucomannan and basal feed. Diversity index and species number of porang glucomannan treatment was higher than konjac glucomannan. Gluco-mannan prebiotics had higher Lactobacillus while the lowest Clostridium was obtained in 0.1% porang glucomannan treatment. The inclusion of glucomannan prebiotics gave no negative effect on the per-formance of broilers.
