EBLING, PD; PONTALTI, GC; VILLANUEVA, AP  e  RIBEIRO, AML. Pendulous Crop in Broilers. Rev. Bras. Cienc. Avic. [online]. 2015, vol.17, n.3, pp.395-398. ISSN 1516-635X.  http://dx.doi.org/10.1590/1516-635X1703395-398.

Pendulous crop is a physiological disorder, which etiology is still unknown and it is characterized by abnormal dilation of the crop of poultry. This article aims at reporting a case of high incidence of pendulous crop in male and female broilers Cobb 500, as well as to discuss its possible causes and consequences. In an experiment with broilers performed at the experimental facilities of Laboratório de Ensino Zootécnico of UFRGS, a high incidence (9.5%) of pendulous crop was observed. Genetic predisposition is the most frequently documented and accepted cause of that condition. Despite presenting the same live weight as normal broilers, birds with pendulous crop had lower carcass weight due to dehydration and malnourishment, and should be culled after diagnosis. Therefore, further studies on the origin and control of this physiological disorder are warranted.
