A Study on Crop Repair by Using Different Ingluviotomy Techniques in Pigeon

Pigeons signify the resourceful class of vertebrates. Their crop is a thin muscular expansion of esophagus which temporarily stores food. Traumatic rupture of the filled crop is common because when expanded to skin, even a small concussion can result in its injury. This project was designed to identify the best and reliable technique for crop rupture repair, with least surgical and post-surgical complications. The study was carried out on 30 apparently healthy pigeons weighing between 275 gm to 350 gm. They were divided into three groups i.e. Group A, B and C comprising ten pigeons each and were numbered as A1-A10, B1-B10 and C1-C10. Ingluviotomy techniques were performed group wise as: for group A-Single Layer closure; group B-Double Layer closure and group C-with surgical glue. Clinical parameters were observed at variable intervals from day 1 to day 30 post- surgery. In vital body signs, temperature (P≤0.05) revealed significant difference between groups whereas pulse rate and respiration showed nonsignificant difference (P≥0.05). Liquid, food intake was superior in group B than group A and C; moreover, group C showed better intake than group A. Droppings were initially watery, which gradually converted from semi-solid to normal with passage of time in all groups. Weight gain/loss, (P≤0.05) revealed significant difference between groups; weight gain was highest in group B, moderate in group C and lowest in group A. Wound healing and leakage evaluations, showed excellent healing with least leakage and associated mortality in group B, whereas groups A and C showed variable leakages with greater mortality in group A than C.
