R₁ Control ration contained 16% soybean meal (SBM)
R₂ Replaced 50% of soybean meal (SBM) by sesame meal (SM)
R₃ Replaced 100% of soybean meal (SBM) by sesame meal (SM)
NFC Non-fibrous carbohydrates = 100 − {CP + EE + Ash + NDF} (Calsamiglia et al. 1995) NFC = 100 − {CP + EE + Ash + NDF}
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 & NFE) = 4.15 kcal
DE (Kcal/kg DM) = GE × 0.76 (NRC 1977)
