Evaluation of teaser buffaloes subjected to surgical technique for fixation of the caudal curvature of the sigmoid flexure with myectomy of the penis retractor muscle

Abstract

The objective of this work was to evaluate the efficiency technique of fixation of the caudal curvature of the sigmoid flexure with myectomy of the penis retractor muscle and the performance of teaser bulls after surgery, through the detection of females in estrus, without performing the copulation. 12 teaser buffaloes were used without defined breed, with an average age of 20 months, weighing on average 200 kg. The animals were subjected to food and water fasting for 12 hours to provide tranquilization in advance. The surgical procedure consisted of the exteriorization of the sigmoid flexure, myectomy of  penis retractor muscle and fixation of the caudal curvature of the penis sigmoid flexure. Of the 12 evaluated teaser buffaloes in the libido test, 100% performed  the  flehmen reflex, mount attempt, incomplete and complete jump  with total inability of  the penis exposure.    It was concluded that this technique can be used safely, having  simplicity in its execution, effective results and mainly low cost, not interfering in the animals’ libido. The animals when tested as teaser buffaloes kept the libido during the experimental period with total inability of exposure of the penis.
