title: Response of broilers susceptible to ascites when grown in high and low oxygen environments.
abstract: 1. Broilers selected on the basis of food conversion efficiency or growth rate were grown under normal (21%) or varied (19%, 23%) oxygen environments. 2. Broilers selected for food conversion efficiency had greater growth rates and superior food conversion efficiencies than broilers selected for growth rate. No interactions between broiler strain and oxygen level were observed. 3. Increasing environmental oxygen level decreased N efficiency in both broiler strains. Nitrogen turnover was non-significantly decreased. 4. Ascites may only occur when broilers are able to cope with small environmental adversities while maintaining optimal growth rates.
