I'll be getting a dexter soon (already bred). I was planning on going the grass-fed route (I have alot of pasture to support her). The question I have is once she has her calf and is in milk, will I need to supplement with grain? I plan on sharing the milk with the calf but wasn't sure if jsut the pasture will support her. Also, when people say dairy grains, what mix are they talking about? I've raised pigs and chicken and am new to cows. If I mix my own grains, what ration should I be doing? Thanks!
