The treatments were control (CON; 27% starch and 4% sugar on a DM basis; Table 1), a high-NFC diet in which dietary starch content was increased by replacing beet pulp in the CON diet with corn grain (STA; 32% starch and 4% sugar on a DM basis), and 2 more high-NFC diets in which dietary sugar content was increased by replacing beet pulp in the CON diet with 5.5% of sucrose (SUC; 27% starch and 9% sugar on a DM basis) or lactose (LAC; 27% starch and 9% sugar on a DM basis).
