　　The feed contains about 15% protein. Among the essential amino acids, arginine is particularly important for rabbits and is the first restrictive amino acid. Therefore, arginine and lysine must be supplemented in the rabbit's diet. Intestinal microbes can synthesize vitamin K and most B vitamins, and use them alone through feces, but vitamin K needs to be supplemented during reproduction. The diet requires a certain amount of crude fiber to maintain normal digestion and physiology, and the crude fiber content in the diet must exceed 12%. However, for sterile rabbits, the crude fiber content in the feed should be reduced and all vitamins should be supplemented at the same time. Rabbits can tolerate high levels of calcium and have high iron reserves at birth, so they are less prone to anemia.
