These toxins are oil soluble and most of the toxin are removed during solvent extraction of oil from cake with hexane. Therefore, de-oiled cakes could be used in compound cattle feed.

(g) The cake contains nitrogen(N) 5.1%, phosphorous( P 2 O 5) 1.1% and potash ( K 2 0) 1.3.% and has been reported as a useful organic manure for sugarcane, coffee, oranges and paddy.
