BREEDING PROGRAMS

Hormone-based breeding programs are another method of improving heat detection.  Hormones allow for manipulation of the estrous cycle to qualify and quantify estrus and subsequent ovulation.  When administered to a group of cows, a program synchronizes their cycles, causing them to come into heat around the same time.  This amplifies heat expression.  Programs also define a period of time during which estrus is expected, and some even allow for automatic breeding independent of standing behavior.
