This study aims to compare the yield and lipid composition of milk in dairy cows depending on the nature of distributed feed supply as concentrate. 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 signifi cant 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 C1 had no signifi cant effect on milk fat composition. The incorporation of concentrate with higher lipid content in the diet of dairy cows increases milk production and modifi es milk fat quality.
