E. Donaldson, V. L. Christensen, J. D. Garlich, J. P. McMurtry, N. C. Olson] Newly hatched, unfed turkey poults are exposed to several post-hatch stressors, each of which can increase the risk of early mortality. The know risk factors for early poult mortality (e.g., hatchery servicing stressors, prolonged holding without feed or water, temperature stress) all are associated with lower than normal carbohydrate (glycogen) reserves and increased reliance on gluconeogenesis (conversion of non-carbohydrates such as protein to glucose, and the poults sole source of carbohydrate prior to feeding). Sub-standard ventilation conditions during holding, transport, or brooding of poults are considered stressful because carbon dioxide levels rise (hypercapnia). Poults were exposed to elevated 0.4%) CO2 for 16 hr posthatch. We conclude from the metabolic effects observed that hypercapnia is a stressor and thus may be an additional risk factor for early poult mortality. © 1995 Applied Poultry Science, Inc.
