“…Perez-Calvo et al (2019) hypothesized that by hydrolyzing bacterial PGN and removing cell wall debris, muramidase enhanced gut function and nutrient digestibility through a reduction in steric hindrance in the intestinal lumen. This has been confirmed more recently, with an improvement in nutrient digestion, including amino acids, and intestinal barrier function reported in broilers fed microbial muramidase ( Goes et al, 2022 ; Perez-Calvo et al, 2023 ). Therefore, improvements in growth performance and carcass yield with the supplementation of muramidase can be linked to improvements in nutrient utilization, including protein, energy, and amino acids.…”

“…An increase in protein and amino acid digestibility may also translate to an increase in protein accretion and breast meat yield. Recently, Perez-Calvo et al (2023) found muramidase supplementation into broiler diets significantly improved standardized ileal amino acid digestibility. In the current study, breast meat yield as a proportion of live weight and percent of carcass yield was greater ( P < 0.05) in birds fed muramidase, regardless of dose, compared with birds fed the control ( Table 4 ).…”

“…MR is able to hydrolyse the β-1-4 glycosidic linkages between with N-acetylmuramic acid and N-acetyl glucosamine into simple carbohydrates and amino acids [ 17 ]. In broiler study, MR supplementation improved ileal amino acid digestibility of crude protein and increased energy utilization [ 18 ].…”

Background Optimal gut health is important to maximize growth performance and feed efficiency in broiler chickens. A total of 1,365 one-day-old male Ross 308 broiler chickens were randomly divided into 5 treatments groups with 21 replicates, 13 birds per replicate. The present research investigated effects of microbial muramidase or a precision glycan alone or in combination on growth performance, apparent total tract digestibility, total blood carotenoid content, intestinal villus length, meat quality and gut microbiota in broiler chickens. Treatments included: NC: negative control (basal diet group); PC: positive control (basal diet + 0.02% probiotics); MR: basal diet + 0.035% microbial muramidase; PG: basal diet + 0.1% precision glycan; and MRPG: basal diet + 0.025% MR + 0.1% PG, respectively. Results MRPG group increased the body weight gain and feed intake (P < 0.05) compared with NC group. Moreover, it significantly increased total serum carotenoid (P < 0.05) and MRPG altered the microbial diversity in ileum contents. The MRPG treatment group increased the abundance of the phylum Firmicutes, and family Lachnospiraceae, Ruminococcaceae, Oscillospiraceae, Lactobacillaceae, Peptostreptococcaceae and decreased the abundance of the phylum Campilobacterota, Bacteroidota and family Bacteroidaceae. Compared with the NC group, the chickens fed MRPG showed significantly increased in duodenum villus length at end the trial. Conclusion In this study, overall results showed that the synergetic effects of MR and PG showed enhancing growth performance, total serum carotenoid level and altering gut microbiota composition of broilers. The current research indicates that co-supplementation of MR and PG in broiler diets enhances intestinal health, consequently leading to an increased broiler production.
