Without exception, visitors to WDE were impressed by the industry’s most highly proven and reliable heat detection program, ai24™. This time-tested program features proven heat detection rates of 85-90% and is reducing days open and increasing profitability on herds across the USA and around the world with over 500,000 collars in use.
