Popis: A meta-analysis was conducted to determine the effects of different types of oligosaccharides (OS) on the egg quality, intestinal profile, nutrient digestibility, and immunity of laying hens. A dataset was constructed from articles published between 2006 and 2023 via a literature search using several keywords related to oligosaccharides and laying hens’ performance. After careful evaluation, the final dataset was developed from 25 in vivo studies comprising 165 comparisons. The meta-regression showed that levels of OS supplementation curvilinearly increased (p 0.05) feed intake (FI), feed conversion ratio (FCR), egg mass, egg weight, eggshell thickness, shell strength, and Haugh unit. OS supplementation showed a positively improved antioxidant activity, as indicated by the curvilinear effect on superoxide dismutase (SOD) and malondialdehyde (MDA) concentration. In the categorical meta-analysis, mannan oligosaccharide (MOS), xylooligosaccharides (XOS), and chitosan oligosaccharide (COS) significantly increased (p
