Abstract

Estrus detection plays a vital role in the success of any artificial insemination program. There are multiple methods of heat de­tection employed on beef and dairy operations. The intact bull that has been rendered sterile is often described a teaser bull. These animals are useful aids for detection of estrus in females that do not display strong external cues that they are ready for breeding. This article reviews the most common techniques employed by practitioners to render a male sterile and still maintain libido. The options to avoid penetration of the geni­tal tract of the female are desirable to limit infectious disease transmission. The vast number of techniques described in the literature are evidence that there is no perfect procedure. This article discusses several common, effective and currently rec­ommended surgical techniques for preparing teaser bulls. The bull selected for these procedures should be young, healthy and have a strong libido. It is also recommended that the candidate for procedures should be easy to handle because of frequent human interactions.
