Description

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.

Objective(s)

  • Quantify and qualify the presence of pathogenic bacteria in the environment (air and litter) in conventional chicken houses and in alternative houses outfitted with enriched cages.
  • Measure the concentrations of gas in both types of housing.
  • Develop a simplified method for assessing air exchange rates in both types of housing while sampling.
  • Compare animal health, productivity, and the quality of the environment in both types of housing.

From 2019 to 2021
