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.
在炎热干燥季节,对120只小母鸡研究了抗坏血酸(AA)、维生素E(E)以及AA与E的组合(AA + E)对八小时公路运输应激的调节作用。所得结果表明,处理、装载和运输会导致淋巴细胞减少、嗜中性粒细胞增多、体重减轻和死亡,在装载和运输前30分钟分别口服每千克体重60毫克AA、30毫克E和60 + 30毫克AA + E可缓解这些情况。研究期间记录的气象条件高于该地区为鸡确定的热中性值(P < 0.05)。总之,在炎热干燥季节,给予维生素AA、E和AA + E,尤其是AA,可降低小母鸡处理、装载、运输和热应激产生不良反应的风险。
