Soybean Doc or meal is a byproduct of a residual substance obtained by the grinding of soybean for extracting oil. The meal is widely used as a protein supplement and filler in animal diets namely; horse, sheep, cattle, pigs, fish, and chicken. The Soya Bean De-Oiled Cakes are rich in natural nutrients and are used widely for feeding purposes. There are basically two categories of Soya meals or DOC: the Hipro (high-protein 50+) soya meal and the regular soya meal (with less protein content than the former 46+).
