The true metabolisable energy content of canola oilcake meal and full-fat canola seed for ostriches (Struthio camelus)

1. The true metabolisable energy (TME) of canola oilcake and full-Eat canol a seed was determined for ostriches to broaden our knowledge of canola as a potential protein and energy source for ostriches. 2. Both test materials were diluted with a basal diet, fed to ostriches and TME-values estimated by multiple regression analysis. 3. The TME values for canola oilcake meal and full-fat canola seed for ostr iches were respectively 13.76 MJ kg(-1) and 22.5 MJ kg(-1). 4. The TME values obtained for these 2 important protein sources will assis t in the more accurate formulation of diets for ostriches.
