I am looking for an online calculator where I can input the day and time that I want to A.I. and it will automatically calculate backwards to the correct day and times to administer the GnRH and and PG injections. I may have to make one in excel but would prefer to find an online calculator. I wonder if there is one for both heifers and cows. It would be very handy if you could input the time you want to administer the first Gnrh injection and CIDR and it would spit out the times for the PG and A.I. Maybe I am just dreaming. Does anybody know if such a thing exists and where I may find it?
