Effects of various supplemental levels of multi-enzyme complex on amino acid profiles in egg yolk, antioxidant capacity, cecal microbial community and metabolites of laying hens.

ABSTRACT: This study aimed to investigate the effects of multi-enzyme (alkaline protease, xylanase, glucanase, β-mannanase, cellulase, acid protease, glucoamylase, and α-galactosidase) on antioxidant capacity, egg quality, amino acid profiles in yolk, cecal microflora and metabolites in laying hens. A total of 384 Jingfen No.6 laying hens aged 65 weeks were randomly divided into 4 treatments groups (6 replicates per group) and fed diets containing 0, 150, 300, or 600 mg kg^-1 multi-enzyme over an 8-week feeding duration. Our findings revealed that supplementation with 600 mg kg^-1 of multi-enzyme significantly increased the albumen height (P < 0.05) and haugh unit (P < 0.05). Moreover, as the levels of multi-enzyme supplementation in the diet increased, there were s
