Influence of animal and plant fat addition in pasture and winter feeding of high yielding cows at first stage of lactation on productivity and physiological profiles.
200 g of fat in the form of greased wheat bran, was given cows during pasture feeding. For winter feeding on hay and silages the amount was 400 g of greased wheat bran or 400 g of oil in ground rapeseed per day and per animal. Influence of the fat addition on the yield and milk composition was observed in the case of pasture experiment. No such influence was observed in the winter feeding. Addition of fat advantageously influenced the chemical constituents in the cow blood in both experiments.
