Improving success of sheep AI program

For many years laparoscopic Artificial Insemination (AI) using frozen semen has produced highly variable results and as a consequence, some producers have been walking away from the technology. Investigations to date have been unable to explain the large variation in conception rates. This project addressed several of these issues by developing new treatment protocol(s) that are able to consistently produce improved levels of synchrony of oestrus. It is anticipated that this new treatment protocol will replace the existing standard treatment protocol that has remained largely unchanged since the 1970s. By examining the effects of body condition score, feed intake and progesterone concentration on synchrony of oestrus, the project also aims to develop improved management strategies for Al programs.
