Concentration in milk production results in an increase in demand for industrial feed mixes used in cow feeding. Concentration processes in Poland are not very well advanced and the average size of cow herd is several times lower than in other EU countries. Domestic use of industrial feed mixes per unit of milk production increases along rising scale of production but is still considerably below the level observed in the EU. In the next years concentration of production will advance a further increase in demand pro industrial feed mixes in the dairy sector is expected.
