You really don't feed copra meal straight or alone. It's typically pricey for most users, but if you have access to it, it's a good protein source. Not as good as soy I would think but good nonetheless. I would personally mix copra meal, oats, barley, and soy together to create a real hot protein grain. I would then feed this to lactating does or growing kids. For bucks, wethers, and dry does I'd probably lean more towards just oats and copra as a daily feed. How much are you feeding currently?
