%X one bioassay was carried out using 21-to32-day old broilers chicks to determine the values of apparent metabolizable energy (ame) and nitrogen-corrected apparent metabolizable energy (amen) of crude soybean oil, corn oil, canola oil, avian fat, coconut fat, swine lard, beef tallow, crude soybean oil + coconut fat and crude soybean oil + beef tallow, both latter in 1:1 proportion. the method of total excreta collection was used for the trials, which lasted 10 days each: the first five days for adaptation and the five remaining days for excreta collection. in the assay, difference was observed among the treatments and between the sexes, with the amen values obtained for the females accounting for 98% of the amen values obtained for the males, on average. the interaction feed x sex showed no difference. the mean values of amen observed for broilers chicks for crude soybean oil, corn oil, canola oil, avian fat, coconut fat, swine lard, beef tallow, crude soybean oil + coconut fat and crude soybean oil + beef tallow, 1:1, were, respectively: 8,273, 8,582, 8,681, 8,511, 7,487, 7,536, 7,227, 8,029 and 8,171 kcal/kg as fed.
