DM, dry matter; CMS, condensed molasses fermentation solubles; DDGS, distillers dried grains with soluble; NEL, net energy for lactation; CP, crude protein; NFC, non-fibrous carbohydrate; NDF, neutral detergent fiber; ADF, acid detergent fiber.
CON, control group, no CMS; CMS1, accounted for 1% of the basal diet; CMS2, 2%; CMS3, 3%; CMS4, 4%.
The premix provided the following per kg of the diet: vit A 8,000 IU, vit D 1,200 IU, vit E 50 IU, Cu (as copper sulfate) 10 mg, Fe (as ferrous sulfate) 100 mg, Mn (as manganese sulfate) 40 mg, Zn (as zinc sulfate) 60 mg, I (as potassium iodide) 0.50 mg, Se (as sodium selenite) 0.3 mg, Co (as cobalt chloride) 0.1 mg.
NEL was calculated according to the Nutrient Requirements of Dairy Cattle: Seventh Revised Edition, 2001.
