Hi, we have been feeding our milk cows 16% dairy feed for years,, but due to the High corn prices, from the feed mill it's almost $21 a hundred, it used to be $15 a hundred, so I'm wondering what I can use for an alternative feed source for them, I did find a feed that's 18% protein that is a 3 way mix of Brewer's Grain, Corn Gluten Pellets, and I think it's soybean meal for the 3rd ingredient. It's 12.50 a hundred,. Would this be ok to feed milk cow's? Or should I keep looking?
