Wheat Bran and Pellets
Bran is the hard outer layer of a cereal grain. When wheat is processed this hard layer becomes a byproduct, and is called wheat bran or sometimes miller’s bran. Wheat bran is rich in dietary fiber and essential fatty acids and contains significant quantities of starch, protein, vitamins and dietary minerals. Wheat bran is used in all animal feed diets and can be supplied in both bulk and in bags.
As wheat bran has a very low density, it is sometimes pelletized in order to increase the bulk density so that higher weights can be loaded for transport purposes.
Maize bran is a by-product of various maize (or corn in the USA) milling processes. This includes the production of maize-based foods, such as maize meal, animal feeds, starch and ethanol production. While maize bran refers to the bran coating removed in the early stages of processing, the maize bran sold for livestock feeding is usually a mixture of the bran fraction and other by-products so can be a loosely defined product of variable composition. Maize bran is a source of bulk fibre in both human and animal diets.
When maize is milled to produce maize meal for human consumption around 30 % of the original maize is left over which is called chop. It is very nutritious and can make a good contribution to the fibre and protein requirements for animal feeds.
Cottonseed hulls are the outer coverings of cottonseeds, and the by-products of the de-hulling necessary for cottonseed oil extraction. It can be used in ruminant feed rations. Cottonseed hulls are one of the best roughages used to add bulk to diets rich in protein and energy, in order to reduce digestive upsets in ruminants.
The brownish portion of rice, which is taken out in fine grain form during de-husking and milling of paddy is the rice bran. The bran is milled into a very fine powder which is much in demand for specialized animal feed rations.
