60 days post calving. Heat detect or Sync?

[Richnm]

64 days post calving and cows have not shown heats, no jumping, sniffing etc. Should I continue to watch for a natural heat for a few more days, or sync ? My buddy told me hit them cows with Cystorelin alone and wait. Any opinions/advice ?

I don't know your cows so I hate to tell you to wait. Generally they start cycling about 45-50 days after calving.

I've had luck just throwing a CIDR in cows for 7 days then pull it and watch for heat.

I know everybody has different circumstances but I've had far more success sticking cows on natural heats.
