Abstract

A healthy digestive tract is essential for all aspects of gamebird production, from early growth to feathering and conformation at maturity, and reproduction. This chapter highlights variety of diseases of the digestive tract that have been documented in gamebirds. Lesions appear grossly as a fine, white “pseudomembrane” or lining in the crop, upper esophagus or oral cavity. When the isopod is ingested by a bird host, the infective larvae then escape and migrate/attach to the proventriculus or gizzard lining where they develop into adults within 27 days. In gamebird chicks, Salmonella most often infects the digestive tract and yolk sac. It can also be harbored in the intestine of adult birds with no clinical signs. The role that viruses play in gamebird enteric disease is poorly characterized. Ascaridia is a genus of nematode residing in the small intestine and the larval stages migrate in other soft tissues during the life cycle.
