The effect of oral administration of conjugated linoleic acid (CLA) on isolation-induced distress behavior in the chick was determined at 5 min intervals over a 15min period. The two groups of 6 birds each were orally administered 1ml of CLA or high linoleic acid (HLA) for 4 days. After the fourth day treatment, behaviors were monitored by video camera. Two isomers of CLA were detected in the brain of chicks treated with CLA. However, CLA was not detected in the brain of the HLA group. In overall means, distress vocalizations (DVs) were significantly lower in the CLA than in the HLA group. Similar tendencies were observed in the number of steps and jumps, but not significantly different between two groups. In conclusion, isolation-induced DVs can be modified by oil source and CLA is a useful oil to reduce isolation-induced DVs in the chick compared with HLA.
