This depends on each individual herd and breed. Some herds have a 60% calving assistance rate, whereas other herds may only have a 1% calving assistance rate.

The first milk that comes from a cow right after calving is not suitable for human consumption. It's gathered from the cow and saved for the calves that have been taken from their moms and fed to them via the bottle. The first milk is called colostrum, which is important for a newborn calf's health and survival.
