Experimental total mixed ration composed of 50% CFM + 50% PVH
Gross energy (kcal/kg DM) was calculated according to Blaxter (1968). Each g CP = 5.65 kcal, g EE = 9.40 kcal, and g (CF and NFE) = 4.15 kcal.
DE (Kcal/kg DM): calculated according to NRC (1977). Using the following equation: DE = GE × 0.76.
Neutral detergent fiber (NDF) was calculated according to (Cheeke 1987). Using the following equation:
NDF = 28.924 + 0.657 (CF %).
NFC: Non-fibrous carbohydrates, calculated according to Calsamiglia et al. (1995) using the following equation:
NFC = 100 – {CP + EE + Ash + NDF}
