Is there any other sign we can look for to tell if the cow is bred? What are the symptoms and causes of false heat? Dr. Riegel comments: The typical signs of heat, or estrus, in cattle are: restlessness: a slight decrease in appetite, Edgar Sheaffer Tim Trayer rumination, and milk production; standing to be ridden by other cows and attempting to nde other cows herself; slight elevation of her tail; and strings of clear mucus hanging from the vulva, or present on the tail or hin dquarters. Although cattle are polyestrus, meaning they will cycle all year long when they are not pregnant, some cows show no clinical sign of heat when their calves are nursing. But, as soon as the calf is weaned, the cow will then begin to show outward signs. Therefore, it would be advisable to have your cows checked for pregnancy by a veterinarian performing a rectal examination. The procedure is relatively safe, and can be done any time after 42 days up until the day of calving. It is important to have a substantial facility to confine the cow while the exam is being done. To have a cow show signs of heat during her pregnancy is not normal, but it is not extremely unusual either. False heats occur when the cows estrogen, the normal hormones produced by a cow, override the pregesterones produced by State hort meeting coming LANCASTER annual state-wide fruit meetings are scheduled for January 29-30-31,1980 at the Hershey Motor Lodge and Convention Center in nearby Hershey.
