Comparisons of turkey embryos incubated in tenuous or dense gas environments--II. Organ growth.
1. Eggs from large white turkeys were incubated in tenuous and dense gas atmospheres. 2. Tenuous gases resulted in heavier embryos until the onset of the plateau stage in oxygen consumption when dense gas environments caused heavier embryos. 3. Tenuous gases decreased heart and lung weight but increased liver weight. 4. Oxygen supplementation in tenuous gases increased liver weights but had no effect on lung or heart weights. 5. The data suggest an interaction of gas density and partial pressures of individual gases which affects breathing and the physiology of developing poult embryos.
