The Impact of feed supply was evaluated by introduction of maize and soya meal (C1), brewer's spent grains (C2) and distiller's dried grains with solubles (C3) into feed regime of Holstein and Montbeliarde dairy cows. Seventy-two Holstein and Montbeliarde dairy cows were followed. in real farming conditions, for a period of 14 weeks. The introduction of cereals stimulated milk production and induced a significant change in its fatty acid composition. C2 and C3 diets showed a rise in unsaturated fatty acids in milk regardless of the cow breed, while diet Cl had no significant effect on milk fat composition. The incorporation of concentrate with higher lipid content in the diet of dairy cows increases milk production and modifies milk fat quality.
