Some cows have a shortened estrus. Concrete flooring in loafing sheds should be scored to provide better traction and allow better mounting. There may be mud on her flanks if in a wet pasture with other cows. Aids for Heat Detection Many systems have been tested to monitor the estrous cycle by recording changes in animal behavior. These methods help track the open cow, the pregnant cow, the repeat breeder or problem cow and the diseased animal.
Several techniques uncover and solve heat detection errors.
Documents allow the owner to check the date of the cow's last heat and when to anticipate her next cycle. This is positive reinforcement. As part of a daily routine, these records prompt the herdsman to watch the animals more closely and become more alert to the secondary or more subtle indications of estrus that are missed with casual glances. They also serve as a reminder to walk through the herd twice daily. The farm's veterinarian has a scheduled examination within 30-40 days postpartum that will detect normal and abnormal reproductive conditions.
