“…Glycans play an important role in shaping both the taxonomy and the functions of the microbiota [ 30 , 31 ]. Previously, Goes et al [ 32 ], Walsh et al [ 11 ], and Bortoluzzi et al [ 20 ] found that supplementation of MR and PG in broiler chickens have beneficial effect on the growth performance nutrient digestibility, apparent ileal digestibility and gut health.…”

“…PG are the major structural components of the cell wall, uniquely found in bacteria, and considered as conserved products of bacterial metabolism and activity modulators in the GI tract [ 35 ]. Recently, Bortoluzzi et al [ 20 ] and Yan et al [ 36 ] demonstrated that PG supplementation group had a beneficial effect on performance in broiler chickens. Furthermore, Walsh et al [ 11 ] found that BW and FCR of broilers were enhanced by PG supplementation in the diet.…”

“…Apajalahti and Vienola [ 19 ] found that certain proteins may be fermented by cecal microbiome and generate metabolites that are detrimental for health and welfare of the poultry. PG are able to in vivo shift the microbiome metabolic pathways towards better protein utilization, improved Microbiome Protein Metabolism Index, which is identified as the ratio between the abundance of beneficial by detrimental genes connected protein metabolism [ 20 ].…”

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.
