Contributions to the study of rooster orchidectomy

Abstract

Castration of the rooster, also called claponage is an operative intervention that contributes to the quantitative and qualitative increase of the meat obtained. The capon is calmer, being concerned only with feeding, and the "crowing of the rooster" disappears because it no longer relates. The meat obtained is superior in terms of quantity and taste, as the slaughter of the capons is performed at an early age compared to the uncastrated ones. These beneficial aspects are reduced by the fact that the intracavitary topography of the testicles exposes to intraoperative accidents which, in most cases, are fatal. (8.3). Due to this fact, the study performed in this surgery aimed to identify the factors that contribute to the occurrence of hemorrhagic accident. In this sense, the hemorrhagic accident was correlated with the age of the rooster at the time of clapping and the operative access used. In the rooster, the testicles are in the abdominal cavity, just before the kidneys (6,10,9). They are oriented parallel to the ceiling of the cavity, at a distance of 0.5 - 1 cm from each other, with the anterior pole reaching the level of the last two ribs, and with the posterior one slightly exceed the costal wall (1, 9). The shape of the testicles is ovoid, resembling a bean, the left one being larger than the right one. Their color is yellowish white. The testicles are held in place by the testicular ligament (mesorchium). which is short and crossed by the spermatic artery and vein. Between the two testicular ligaments, under the spine, the aorta and the caudal vena cava have passed, vessels of vital importance having thin walls as they are protected by the testicles in this area. In roosters over six months of age, these vessels are so developed that damage to their integrity causes heavy bleeding. Due to this fact, the capping operation can be accompanied by the danger of a fatal hemorrhage (1, 2, 4, 7, 8).
