I always feel like in intervene too quickly. Calf just born. Birth was quick and easy. Bull calf got up quickly and is quite active running circles around momma. However, no particular evidence he has any desire to suck anything. He will occasionally put his nose into the bag but then quickly turns to do more laps, investigate the water tank, study the fence or whatever else is catching its fancy. How long do you wait before you need to get colostrum in them. I know their gut closes to it in 24 hours and "the sooner the better" - but it also seems forcing the issue isn't always helpful either. Should you wait 12 hours if you have what appears to be an otherwise very healthy normal calf?
