This project aims to measure the impact of new breeding systems that meet new animal welfare standards regarding air quality and the health and productivity of laying hens. A total of 12 conventional chicken houses and 12 alternative houses outfitted with enriched cages will be selected. Eggs, litter, and feces will be sampled weekly. Necropsies will be performed on a sampling of animals each month and air quality samples will be examined periodically.
From 2019 to 2021
