Colostrum is on my mind because, as many of you know, we just had a new calf and I always have that moment of stress wondering if the mama cow will have enough colostrum for her calf!
Why the first 2 hours? Because that is when the calves’ bodies are most receptive to the transfer of antibodies. Colostrum is still beneficial up to 12 hours after birth but it becomes less and less effective the older the calf is at the time of feeding. Because of this, we feed a half gallon immediately after birth for optimal effectiveness and another half gallon 10-12 hours later for good measure.
