Good heat detection requires good knowledge of the following behavioural signs: Introduction Accurately detecting heat (estrus) is a critical facet of both artificial insemination (AI) and embryo transfer (ET) programs. Administering two prostaglandin injections 14 days apart and 12 to 14 days prior to Ovsynch will improve results. When the time comes to examine a herd's dairy reproductive management program, producers often want to discuss low conception rates. Peak heat activity occurs approximately 48 to 72 hours after prostaglandin. 2. Conception rate (CR) is the proportion of cows that are inseminated and become pregnant (US dairy herd average is 40 per cent).
