CALCULATION OF ECONOMIC WEIGHTING FACTORS IN SWINE PRODUCTION

Evaluating the biological technical development the economic values of the production and reproduction traits for the farms were calculated. The economic values were calculated with farm models differentiating between marginal proceeds and marginal cost. The results were as follo ws: Economic values are nonlinear and decline as the level of producti on increases are governed by feed prices for daily gain, feed conversi on and feed intake for lean meat percentage depend on the premiums and the upper limits of the paying systems for meat quality depends on th e specific population distribution of the trait and the paying system.
