Modulating Role of Vitamins C and E against Transport-Induced Stress in Pullets during the Hot-Dry Conditions.

Abstract

The modulating effects of ascorbic acid (AA), vitamin E (E), and a combination of AA and E (AA + E) against eight-hour road transportation stress were investigated in 120 pullets during the hot-dry season. The result obtained showed that handling, loading and transportation induced lymphopenia, neutrophilia, liveweight loss, and mortality, which was alleviated by oral administration of AA, E, and AA + E at doses of 60 mg, 30 mg, and 60 + 30 mg per kg bodyweight, respectively, 30 minutes before being loaded and transported. The meteorological conditions recorded during the study period were higher (P < .05) than the thermoneutral values established for chickens in the zone. In conclusion, the administration of vitamins AA, E, and AA + E, especially AA, ameliorated the risk of adverse effects of handling, loading, transportation, and thermal stress in pullets during the hot-dry season.
