Please be careful with replacers, in general their protein is too high for goats, and beyond and worse than that, they can often become contaminated. A couple of years ago a friend of mine was using replacers, and she kept loosing kids. She had the replacer checked, and it had salmonella, 3 bags later, it still tested positive. If replacer is all you can get, then yes use replacer. But fresh goats milk is best, and whole cows milk works well especially in diary kids. For Pygmys I use full fat half and half, and btw, they have never had a problem with digestion. I have tried several recipes over the years, and found they all caused scouring in my goats, probably because I didn't shake the mixture well enough at each feeding, but none the less, I don't need more work, and dirty bottoms.
