Interaction between ascites susceptibility and CO(2) during the second half of incubation of two broiler lines: the effect on post-hatch development and ascites mortality.

Abstract excerpt

1. The aim of this study was to investigate if genetic predisposition to ascites interacts with changed incubation conditions, and how this might affect the post-hatch performance and ascites susceptibility. 2. An ascites sensitive (A) and resistant (E) broiler line were incubated under standard or high CO(2) conditions (up to 4%) from embryonic d 10 onwards. After hatch, chicks were exposed to cold from the...
