This study was carried out to determine the estimation of effects three doses (0, 0.15, 0.3 ml/30 ml buffered rumen fluid) of thyme methanolic extract on the metobolizable energy of canola meal using the nylon bags technique. Degradation procedure was performed using nylon bags filled with 5 g of canola meal and suspended in the rumen of three fistulated Gezel rams for 0, 2, 4, 8, 16, 24 and 48 h and obtained data were fitted to a non-linear degradation model to calculate ruminal degradation characteristics. Results showed that Metabolisable energy was 2033.95 (K. Ca/Kg DM) for canola meal. Metabolisable energy was 2013.67 (K. Ca/Kg DM) for thyme methanolic extracts (0.15 ml/30 ml buffered rumen fluid). Metabolisable energy was 2003.4 (K. Ca/Kg DM) for thyme methanolic extracts (0.3 ml/30 ml buffered rumen fluid).
