Twenty multiparous Friesian cows, 70 to 90 days postpartum, were allotted to two groups of 10 cows according to calving date, lactation number, and daily milk production and were assigned randomly to one of two diets. The control diet was 50 % maize silage, 14 % ground maize, 7 % soybean meal, and 29 % concentrate. The concentrate contained ground maize, wheat bran, soybean meal, and mineral-vitamin mix. Dried molassed sugar beet pulp pellets were 14 % in the treatment diet, replacing an equal proportion of ground maize. The two diets contained similar quantities of crude protein and metabolizable energy. The dry matter, metabolizable energy and crude protein intakes, milk production, and milk protein, lactose, total solids ans solids not fat contents, as well as milk fat and protein yields, were not significantly affected by the addition of dried molassed sugar beet pulp pellets to died. In contrast, sugar beet pulp supplementation increased milk fat content. No differences were observed in the blood serum concentrations of glucose, total protein, albumin, urea, triglycerides, cholesterol, Na, K, Ca, P and Mg.
