[QUOTE="edrsimms, post: 668592, member: 10970"] On one hand, this depends alot on whether or not you have sychronized your cows/ heifers???? You didn't state that --so we have no idea. If you have synchronized them with (e.g. CIDR's) then you should see standing heat and follow the am/pm rule then by hour 80 AI all who have not shown heat, but never, ever AI them on an 8 hour deal-- later is better than earlier. If you are looking for a livelihood that is in tune with your 8-hour day--- Wal-mart is looking for help. On the other hand if you are watching for natural heat and following the am/pm rule you should already know what their cycle is prior to breeding (e.g. is she a 17 day cycler or 18 or 19 or 20 or is she a 21?) You should already know this information between calving and your first AI attempt when normally a cow comes into heat around 55 days. Also some cows wont show heat if you are breeding during a warm spring-- cooler temps increase conception rates -- heat stress is a killer on heat detection....... Hope this helps [/QUOTE]
