Bran — the by-product of flour-grinding production, represents a firm cover of grain. It is not necessary to confuse to chaff.

Most often bran is fed to dairy cattle, then used in large numbers at a stoutening and cultivation of young growth. To horses and pigs bran is set in the form of swill, to cattle and sheep or in the form of medley with a straw sechka and chaff, or with watery sterns.

Too large amounts of bran at long dachas, can cause weakening of digestive bodies in animals. In some exceptional cases formation of stones from fosfornokisly salts is caused by excess feeding bran: at horses — in thick and blind guts, at sheep — in a bladder.
