Soya Bean Meal being one of the best vegetable protein sources in the world is basically one of the by-products obtained from the extraction of Soya bean oil. As per difference extraction procedures, it is classified into two main categories: Hi-protein or Hipro Soya Bean Meal (consisting of 47-49% protein and 3% crude fiber) obtained from de-hulled seeds and the regular or conventional Soya meal (consisting of 43-44% protein) with hulls.
Hipro Soybean meal contains a better concentration of protein than probably regular soybean meal because the hulls present in conventional meal standardize the Crude Protein level to range between 46-48%. However, the Crude Protein in De-hulled Soybean Meal ranges from 48% onwards. It has a higher energy value as compared to other protein sources as 95% of nitrogen present is actually a true protein. The solubility index of the soya meals is 80-85% and the amino acids are better digested than most other protein sources of plant origin. It also has a better amino acid profile and low fiber percentage than probably normal soybean meal and is used generally for aqua and poultry feeds. The Hipro Soya bean meal is also a good source of phosphorous, iron, vitamin, and minerals and a widely accepted replacement for fishmeal in aquaculture diets.
