Sometimes is it just those stupid first time momma cows who just don't know what is happening and won't understand until they are taught the hard way. I hope that is the case and she figures it out, but if not, she wouldn't be the first cow that ended up making hamburger because she wouldn't mother her own calves.
With rabbits, we breed more than one doe at a time so that if one momma doesn't take care of them, you always have another who will foster them. Sometimes cows will do that but sometimes they won't, so that isn't always an option either.
When you have milking cows, you don't put calves on them to feed and they usually produce way more milk than one calf needs anyway, so you would save the colostrum like Holm did and use it when needed rather than wasting it. It is not good for human consumption, and if you ever saw it, you would know why. It is loaded with natural antibodies and nutrients that even if fed to a started calf who has been away from it, it will throw it into scours/bad diarrhea.
