True metabolisable energy values of some feedingstuffs.
1. The apparent metabolisable energy (AME) and the true metabolisable energy (TME) contents of some feedingstuffs were determined with cockerels. The test materials consisted of feed-grade lentil, lentil bran and wild vetch seed. 2. The average values of nitrogen lost, endogenous energy losses (EEL) and endogenous energy losses corrected to zero-nitrogen balance (EELN) were found to be 1.18 g, 62.13 kJ and 21.51 kJ/bird/48h, respectively, from adult cockerels given an energy supply as 50 g glucose during starvation. 3. The nitrogen-corrected apparent metabolisable energy (AME(N)) values for feed-grade lentil, lentil bran and wild vetch seed, respectively, were 6.84, 3.05 and 14.31 kJ/g dry matter. The nitrogen-corrected true metabolisable energy (TMEN) values for the respective feedingstuffs were 7.44, 3.65 and 14.90 kJ/g dry matter.
