Abstract
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.Entities:
