Triticale, a hybrid of wheat and rye is an alternative cereal grain to maintain the metabolisable energy of poultry diet (Zarghi, H., and A. Golian, 2009). The chemical composition and metabolisable energy of triticale may vary based on the agronomical conditions. The purpose of this study was to determine the nitrogen corrected true metabolisable energy (TMEn) of triticale produced in the northeast of Iran, and in addition, to investigate the relationship between chemical composition and TMEn of triticale for poultry. Ten triticale samples were collected randomly from different locations in the northeast of Iran (Khorasan Razave Province). The samples were analyzed for dry matter, ether extract (EE), crude protein (CP), crude fibre (CF), ash and calculated nitrogen free extract (NFE). The precision-fed rooster assay, Sibbald (1982) was used to determine the TMEn of samples. Fifty five adult cockerels (Hy-Line, average weight of 2030 g) were housed in individual metabolism cages and fed a maintenance diet for two weeks of adaptation. At the start of the experiment on the third week, following a period of 24 h feed restriction, 25 g of each ground sample was fed to a bird by intubation with five birds per sample. Five feed restricted cockerels were kept deprived of feed to estimate the endogenous energy losses. Total excreta voided over the following 48-h period were collected, dried and ground for subsequent analyses. Gross energy (GE) of feed and excreta samples was measured in a Bomb-calorimeter (Model 1266, PARR). The average and standard deviation (SD) of chemical composition of the ten triticale samples is shown in Table 1. A wide variation in CP (113 to 157 g/kg as-fed basis) and NFE (689 to 745 g/kg as-fed basis) was found between triticale samples. The determined TMEn of the samples collected from different locations varied between 12.51 and 13.70 MJ/kg on as-fed basis. The regression equation describing the relationship between the TMEn and chemical composition of the triticale samples is shown in the following formula: TMEn (MJ Kg-1 as-fed basis) = -0.817 + 0.125 EE – 0.008 CP + 0.018 NFE r2 = 0.77
