Two trials with Lithuanian Black-and-White cows were carried out on the Experimental farm of the LVA Institute of Animal Science to determine the effect of maximum amount of sugar beet pulp silage in the diets of cows on milk yield, the nutritive and technological values of milk. The results from the trials indicated that the average whole milk yield of the cows that had diets containing various silages (maize and sugar beet pulp or grass and sugar beet pulp) was, respectively, 15.1 and 0.5% higher if compared with the cows given only homogeneous silage (maize or grass). Partial replacement of maize silage with sugar beet pulp silage resulted in higher contents of protein, casein and mineral matter by, respectively, 0.19 (P0.05), 0.22 (P0.05) and 0.03% (P0,05) and 3% lower content of urea (P0.05) in the milk of cows. However, partial replacement of grass silage and up to 30 % of compound feed with sugar beet pulp silage had no significant influence on the nutritive value of milk and its technological properties. Sugar beet pulp silage may be succesfully used in the diets of milking cows as partial replacement of maize, grass silage (50-60%) and of about 30% of compound feed with no negative influence on the composition and technological properties of milk
