Six indigenous vegetable protein sources viz. soybean meal, canola meal, rapeseed meal, guar meal, sunflower meal and linseed meal were used. Thirty five 18 weeks old broiler breeder cockerels were used in such a way that five birds were force fed 25 gm of each feedstuff for estimation of AME and TME. Five birds were kept fasted to serve as negative control for determination of metabolic faecal and urinary endogenous energy excretions. The pre-feeding fasting period was 24 hours and excreta was collected over a period of 24 hours. The gross energy of test ingredients and the excreta was measured by using adiabatic oxygen bomb calorimeter. Proximate analysis for moisture, crude protein, ether extract, crude fiber, ash and nitrogen free extract were carried out. All had almost similar dry matter and ether extract values. Sunflower meal and canola meal had less CP% because of presence of sulphur containing amino acids. The observed AME values for soybean meal, canola meal, rapeseed meal, guar meal, sunflower meal and linseed meal were 2556, 1920, 1887, 1847, 1629 and 2061 Kcal/Kg, respectively. Soybean meal had the highest value 2556 Kcal/Kg and sunflower meal had the lowest value 1629 Kcal/Kg. The observed TME values for soybean meal, canola meal, rapeseed meal, guar meal, sunflower meal and linseed meal were 2694, 2053, 2022, 1992, 1764 and 2198 Kcal/Kg, respectively. Soybean meal had the highest value 2694 Kcal/Kg and sunflower meal had the lowest value 1764 Kcal/Kg. Endogenous energy ranged from 2.93 Kcal/gm to 2.95 Kcal/gm with the average of 2.94 Kcal/gm. It was also found that crude fiber has indirect relationship with both AME and TME. While, it has also come to notice that ether extract has direct relationship with gross energy of the feedstuff.
