The effect of intrayolk administration of docosahexaenoic acid (DHA) on distress behavior after hatching was investigated using two types (with or without phospholipid) of DHA. Hatchability was decreased by both types of DHA, but there was no difference between sources of DHA. At two-days-of-age, birds from each treatment were individually isolated and distress vocalizations (DVs) were counted for 10min. DVs tended to decrease faster in DHA-treated birds compared with the control, but the effect was not significant. Thereafter, food intake following the intracerebroventricular injection of corticotropin- releasing factor (CRF) was monitored in three-day-old birds from each treatment. Birds hatched from eggs injected with DHA without phospholipid rapidly overcame the food intake suppression caused by CRF when compared with other treatments. In conclusion, birds hatched eggs rich in DHA may be better adapted to stressful circumstances.
