Comparação do método da amputação do II e III metacarpianos (pinioning) e da termocauterização para coibir o vôo em pombos (Columbia livia)

Abstract

That experiment had as objective evaluates the effect of the termocauterization of the follicle after the removal of the feathers primary (remiges) and of the amputation of the II and III metacarpus (pinioning) to obstruct the flight in pigeons (Columba livia). Thirty adult birds were used, 15 males and 15 females. Three treatments was utilized (group 1 the pinioning technique was used; in the group 2 was practiced the termocauterization of the follicle after the removal of the feathers primary (remiges); and the group 3 was used as control group), and ten replications each in a complety randomized desing. When the pinioning technique was used, there was not growth of the feathers primary remiges, except in a bird (10%), but all birds not flight. In the group in that the termocauterization was used observed necrosis and typical signs of burns, besides replacement partial or total of the feathers primary remiges. In that group two birds they usually flight and three flight with difficulty. Evaluating the two procedures, conclusion of the pinioning technique obstruct the flight in 100% of birds, while the termocauterization only 20%.
