compared with those fed the CON diet, whereas the yields
of milk protein did not differ. In addition, cows fed
high-NFC diets had lower MUN concentration than
those fed the CON diet (P < 0.01). Cows fed highdisaccharide
diets tended to have higher (P = 0.06)
milk yield compared with those fed the STA diet, and
they had higher (P < 0.01) ECM than those fed the
STA diet. Cows fed high-disaccharide diets had greater
milk fat yield (P = 0.01) and protein yield (P = 0.02)
and tended to have greater milk protein concentration
(P = 0.09) compared with those fed the STA diet. Milk
and milk component yields did not differ between cows
fed the SUC diet and LAC diet, but cows fed the LAC
diet tended to have higher milk fat concentration (P =
0.06) than those fed the SUC diet.
