The effect of supplementing the feed of broiler chicks with different levels of ascorbic acid on the resistance against infectious bronchitis virus was investigated. Resistance was measured by the severity of tracheal lesions and the development of airsacculitis after challenge. The effect of ascorbic acid was dose dependent. Addition of 300 to 330 ppm ascorbic acid to the feed gave the best results. High concentrations (>600 ppm) had a less beneficial effect.
研究了在肉鸡雏鸡饲料中添加不同水平抗坏血酸对抵抗传染性支气管炎病毒的影响。通过气管损伤的严重程度和攻毒后气囊炎的发展来衡量抵抗力。抗坏血酸的作用呈剂量依赖性。在饲料中添加300至330 ppm抗坏血酸效果最佳。高浓度（>600 ppm）的效果则不太理想。
