Determination Metabolizable Energy Content of Soybean, Sunflower and Canola Meals, Using Adult Cockerels

The experiment was conducted to determine metabolizable energy contents of soybean (SBM), canola (CM) and sunflower (SFM) meals from differences manufactory processing oil seeds. Nine samples of SBM, four samples of CM and four samples of SFM were evaluated using conventional addition method (CAM) with adult cockerels for a seven days experimental period consisting 4 days pre-collection and 3 days collection periods. The results have indicated that apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), true metabolizable energy (TME) and nitrogen-corrected metabolizable energy (TMEn) were different within samples of SBM, CM and SFM meals (P<0.05). The averages of AME, AMEn, TME, TMEn values for SBM, were 2439.12, 2439.14, 2636.16 and 2636.27; for CM were 2058.07, 2058.58, 2177.72 and 2177.94; and for SFM were 1426.80, 1426.87, 1587.35 and 1587.46 kcal/kg, respectively. The result of experiment confirms that amount of metabolizable energy content of soybean, canola and sunflower meals can be influenced by chemical nutrients, variables and manufactory processing respectively.
