CROP DISORDERS IN BABY BIRDS - Scott E. …
CROP DISORDERS IN baby BIRDS Normal structure and function of the crop The crop is a dilatation of the esophagus found in many (but not all) species of BIRDS . It is prominent in psittacines. The crop is located just cranial to the thoracic inlet. It is firmly attached to the underlying skin and thus can easily be seen and palpated externally. The crop in parrots is oriented transversely across the neck. Food enters from the right side and exits caudally on the midline. When the proventriculus (stomach) and ventriculus (gizzard) are full, food may be stored in the crop. Stored food undergoes softening and swelling, but no chemical digestion takes place. Food eventually is moved caudally from the crop by powerful smooth muscle contractions of the crop and the esophageal wall. The crop (and proventriculus) is much larger in preweaned psittacines than in adults to accommodate the large volume of food required for rapid growth.
