Squamous metaplasia of the glandular epithelium was found in the palatine salivary glands of two canaries, originating from a flock in which there was a variable intake of egg food. The histological changes, in combination with the history, indicate a vitamin A deficiency as a result of a selective intake of food as the most likely aetiology.
在两只金丝雀的腭唾液腺中发现了腺上皮的鳞状化生，这两只金丝雀来自一个蛋食摄入量不一的鸟群。组织学变化结合病史表明，由于选择性进食导致维生素A缺乏是最可能的病因。
