Key result
Dietary flax oil reduces mortality, ascites, and pulmonary hypertension in high-altitude broiler models.
Why the study?
The effect of dietary flax oil on pulmonary hypertension, ascites, and related outcomes in broilers under ambient and hypobaric hypoxia conditions was examined.
Does dietary flax oil reduce mortality, pulmonary hypertension, and ascites in broiler chickens exposed to hypobaric hypoxia?
Population
Broiler chickens housed at ambient pressure or in hypobaric chambers simulating 1000, 1500, or 2200 m altitude
Comparison
Diet containing 100 g/kg added fat as flax oil vs diet containing 100 g/kg added fat as animal/vegetable blend
Design
Experimental study with hypobaric chamber exposure and dietary intervention

Does dietary flax oil reduce mortality, pulmonary hypertension, and ascites in broiler chickens exposed to hypobaric hypoxia?
Dietary flax oil may effectively reduce ascites and pulmonary hypertension in broilers exposed to hypobaric hypoxia without affecting performance.
Bond et al. (1996) studied Pulmonary hypertension and ascites. Dietary flax oil vs. Animal/vegetable (A/V) blend was evaluated on Mortality and incidence of pulmonary hypertension and ascites. Dietary flax oil decreased mortality and the incidence of ascites at 2200 m and pulmonary hypertension at 1500 m in broiler chickens without affecting performance.
