We start charting heat cycles a month or 2 before the start of our breeding season. Anything that we haven;t observed in heat by the end of the first 3 weeks of breeding season we;ll give the GnRH. Only happens once every few years. Never have given it when we bred.
I only gave GNRH to the 4 that I didn't observe coming into heat. Dun's method of heat detecting, and AI is probably the best as far as conception rates. If I didn't have an 8-5, that is the way I would do it. I had observed all of the mature cows in heat prior to the CIDRs, but don't chart it due to the synch program.
