Bharat Agro - Rapeseed Meal
Rapeseed meal is the by-product of the extraction of oil from rapeseed (Brassica napus L, Brassica rapa L. and Brassica juncea L, and their crosses). It is a protein-rich ingredient that is widely used to feed all classes of livestock. While solvent-extracted rapeseed meal remains the main type of rapeseed meal commercially available, oil-rich rapeseed meals obtained by mechanical pressure have gained popularity since the turn of the century with the development of organic farming and on-farm oil production.
Rapeseeds are first crushed to remove the oil, yielding rapeseed cake as the first by-product. In most cases today the cake is further processed through solvent extraction, yielding rapeseed meal as the final product.
On average, rapeseed meal contains on an as-fed basis (90% dry matter) 36-38% crude protein, 10-12% crude fibre, 1-2% lipids (oil), 6-8% ash, less than 1% calcium, and 1.2% total phosphorus. Composition varies widely depending on factors such as origin, growing conditions, the manufacturing process and degree of oil extraction.
