Inducing heats in cows not detected without prior scanning is not advisable

Cow scanning on farms at this stage of the production cycle, in spring calving herds, reveals that up to 10% of cows submitted for A.I. and presented at the incorrect stage of the estrous cycle. Cow scanning as shown, introduces either uterine infections or embryonic death. The problem is exacerbated on those farms attempting to achieve high submission rates, when dependant on estrous detection heats, such as tail paint, chin ball markers, heat mounted detectors, or activity monitors.
