Gro-Trac® is a state-of-the-art equine growth-monitoring software that allows breeders to compare the growth rates of their stock with those of young horses of similar age, sex, and breed. By using the world’s largest set of growth records collected by Kentucky Equine Research over the past two decades, breeders can quickly assess how their young horses stack up against their peers. Peer reference groups include the weights, heights, and average daily gains of tens of thousands of growing horses from around the globe. Weight and height statistics can be displayed graphically for quick visual assessment of growth, allowing users to identify and address growth anomalies early. Graphs show the growth curve for the young horse as well as the reference group of choice. Data may be viewed by individual, or as averages of user-defined groups and the entire farm. Combined, these records create a picture of each horse’s individual development and overall farm management.
