Evaluating the reproductive ability of breeding stock is crucial for cow/calf operations. Cattle that have irregular estrous cycles often have difficulty becoming pregnant, thus increasing the total days open and reducing the total pounds of calf weaned per cow exposed.
There are many advantages associated with proper estrous detection. When estrous detection, also known as heat detection, is performed correctly, producers can facilitate management activities such as artificial insemination and embryo transfer. Identifying and culling females with reproductive problems can improve overall profits by reducing feed costs and increasing uniformity in the calf crop.
