1.3 By-products
In the above characterization of the major oil plants, reference has been made to the main use of the crops, i.e. in most cases the extraction of vegetable oil which, in turn, is used mainly for food and, to a lesser extent, for technical purposes.
In the present chapter, the by-products obtained from processing the above oilplants for oil are summarized (see Table 6).

High protein containing oilcakes are much too rich to be fed directly to animals. They have to be mixed with starch and fibre containing feedstuffs in order to be properly digested. Handbooks on animal husbandry will provide detailed information on how a proper animal feed can be prepared with oilcakes as ingredients.
In Table 7, some examples are given of the composition of locally produced oilcakes of important oil seeds.
