Metabolisable energy value of sugar cane molasses was determined in a balance study with seven month old ostriches. A true metabolisable energy value, corrected for zero nitrogen (N) retention (TME_N), of 7.77 MJ/kg on an air dry basis was calculated. Literature stated values of 8.3 and 9.8 MJ/kg on a 75% dry matter basis for poultry and pigs, respectively. It seems that inclusion level, as found with ruminants, might have an influence on energy value of molasses for ostriches. The energy value determined for molasses could be add to the list of feedstuffs already evaluated for ostriches.
