Extract

Since whole rapeseed is a high energy feed source but only moderate in protein content and value it is desirable to combine it with another feedstuff such as peas so that the combined product has an improved balance of amino acids and a more favourable protein to energy ratio. Extrusion is a useful method of processing a rape:pea mixture since this results in effective release of oil from the rape and its absorption by the pea. The heat generated by extrusion could also lead to the destruction of heat labile anti-nutritive factors in both rapeseed and peas.
