Abstract

This project contains supplementary materials, datasets, and analysis scripts for the systematic review and meta-analysis published on the efficacy of various butyrate formulations on egg production and quality in laying hens. The study synthesizes evidence from 29 controlled trials to assess the effects of butyrate salts, coated butyrates, and glycerides on key performance metrics including egg production, egg weight, shell quality, and yolk color.
