The calculation of a relative feed value is a simple technique which is used to determine whether a particular feedstuff is value for money relative to a set of reference feeds. Barley and soya are used as the reference feeds. Processing costs are not included in the calculation.

Straights vary in terms of nutrient composition.
It is advisable to have an analysis of the feed available before calculating its relative feed value. The figures given will vary according to the price of barley and soya.
