as said start her on feed very slowly.an slowly increase it till she is eating 10 to 12lbs of feed at a milking.if she is milking as heavy as you say.she is milking herself to death.she needs a 16% dairy feed.
We have our customed mixed so I can't recommend any specific one. I would wonder about the 44% protein ones though. They sound like a premix-ones that you mix corn etc with. Percent wise, I would aim for, 18-20%. If she is giving more milk than you can use you could try a 16%. You asked about beet pulp. Some do use it with cattle. It's safe for them.freetodream said:Any particular dairy mix you all recommend? I was looking and purina alone has at least 8 different formulas for lactating cows! I feel a little lost. Some have up to 44% protein but I can't see that more would necessarily be better? Any guidance?
