Effect of Pendulous Crop on Certain Clinicopathological and Biochemical Parameters in Japanese Quails

Objective: The aim of this study was to determine clinicopathological findings and certain biochemical parameters of quails diagnosed with the pendulous crop. Material and Methods: The animal material of the study consists of a total of 3 Japanese quails (Coturnix coturnix japonica) of 4 to 6-week ages, of which 2 were females and 1 was a male. The quails were examined clinically first, followed by the post-mortem examinations. The blood samples for the biochemical analyzes were collected during the slaughtering of the animals. The investigations of sodium (Na), potassium (K), magnesium (Mg), total protein (TP) and albumin (Alb) were conducted using an ADVIA 1800 Chemistry System autoanalyzer. Results: In addition to findings of dehydration in animals, inspections have revealed that the ventral part of the animals’ necks were abnormally dilated, and their crops were full and bulging. The plasma levels of sodium (Na), potassium (K), magnesium (Mg), total protein (TP) and albumin (Alb) in the blood samples collected from the animals were found to be higher than the averages for quails. Postmortem examination of quails has revealed that the veins of their crops were prominently pronounced and that the crops were filled with a yellowish, foul-odor liquid containing whole grain particles. Furthermore, the crop mucosa of an animal contained ulcerative lesions. Conclusions: As a result, it was found that certain mineral levels and protein profiles of animals were affected by the pendulous crop phenomenon, and that laboratory findings should be considered alongside physical findings when dealing with it. It was also surmised that it could be possible to reduce the incidence of the disease by improving the conditions of animal care and nutrition.
