ECD (The efficiency of conversion of digested feed, %) = Biomass gained (g)/Total feed consumed (g) × 100.
FCR (Feed conversion rate, %) = Feed intake (g DM)/Weight gained (g DM) × 100.
Degradation (%) = (Initial feed dry weight (g) − Final feed dry weight (g))/(Initial feed dry weight (g)) × 100.
NM: Not mentioned.
