Our studies have shown that the barium sulphate solution that was administred to the pigeons (found in a light estate of stress, because of the handling) passes too quickly through the glandular and the mechanic stomach, which cause this area to remain unmarked, from a radiologic point of view. Thus, we thought of delaying the peristaltism using an anesthetic – in one of the cases, we administred Ketamine in a dose of 2 mg/100 g of body weight, after which we proceeded with the radiologic examination, in a latero-lateral position (the pigeon was held on its’ right side, with the wings fastened to the back, and the legs drawn to the back).
