In this paper a multiple output cost function framework is proposed to construct national feed balances or feed utilisation matrices (FUMs). The framework is applied to Belgian compound feed industry. For estimation purpose a symetric generalized McFadden (SGM) cost function is selected. The cost function is estimated using readily available time-series data for the period 1962-1988. Unlike previous studies based on duality theory, this study exploits the properties of nonjointness in animal feed production to establish a complete FUM. The allocation of feed ingredients among different livestock categories as well as the composition of various feeds are identified. also own- and cross- price elasticities of demand for feed ingredients by type of livestock are reported.
