I have a new nigerian dwarf doe. She was fed a 16% dairy ration. My husband had bought a 14% goat ration from our local mill before we brought her home. Is there a supplement we could mix in to increase the protein to 16% or should we return the 14% and just buy a commerical 16% ration? Just not sure if the mill will take the 14% back or not......We only bought 2 goats (one is a baby) to start with, but have 200 lbs of 14% feed. Why do some dairy goat owners feed 16% to lactating does, while others feed 18%? Thanks for the advice!
