Such a tease! Production and uses of teaser rams, bucks, boars and bulls

Crilly, JP; Reilly, B; Wood, Max

Abstract

Background: Male livestock rendered sterile through vasectomy or epididymectomy, but still hormonally and behaviourally sexually active, have many uses. In small ruminants they can be used to advance the breeding season and puberty, synchronise and detect oestrus and improve conception rates to artificial insemination. In pigs, they can be used to hasten first oestrus in gilts and detect oestrus in sows. In cattle, they can be used to aid heat detection for artificial insemination. Aim of the article: This article outlines the surgical techniques used to produce such 'teaser' animals and discusses how they can be best used, as well as the alternatives to their use.
