The effect of night transportation on the heart rate and skin temperature of ostriches during real transportation

Literature has identified a number of stressors that have negative impacts on the welfare of ostriches during transportation. In order to maintain or improve the welfare of animals it is important to minimise or eliminate the impact of such stressors. Literature suggested that ostrich welfare during transit might be improved by using darkened vehicles. A preliminary study was carried out which measured the response of ostrich heart rate and skin temperature (indicators of stress) to transportation. Comparisons were made between transportation during the day and at night. Statistical tests suggested that heart rates and skin temperatures recorded during the night were lower than those recorded during the day. The usual response of ostriches to darkness is to sit, which provides greater stability for the bird while the transportation unit is in motion. Temperatures inside the transportation unit were significantly lower at night. This may also contribute to the lowering of heart rate and skin temperature as it reduces effects of heat stress. The conclusion has been drawn that transporting ostriches at night is potentially beneficial for the reduction of stress and maintenance of welfare. (C) 2002 Elsevier Science Ltd. All rights reserved.
