Adulteration is defined as the admixture of a pure substance with some cheaper and low quality substance.
- It is done intentionally usually to make money.
- In costly feed ingredients like oil seed cakes and feeds of animal origin like fish meal, adulteration is done by spraying urea in order to raise their protein content.
- However, sometimes brans, molasses are also added.
- Besides urea, oilseed cakes are adulterated with husk, non-edible oilseed cakes.
