I've read that generally you want to keep you feed protein percentage lower than 20% after grow out. But, the only low protein feeds that I've seen at the stores is way more expensive than the rest and very rarely in stock. So, if my research is correct that protein levels should be lower, what do you guys mix with high protein feeds to make them more appropriate? Especially with pellets the lowest protein. Pellet I've been able to find is 22%.
