The Determination of Metabolizable Protein of Untreated and Treated Canola Meal with Urea and Microwave Using Nylon Bags Technique

This study was carried out to determine the nutritive value of canola meal treated and untreated with 0.5% urea and microwave using nylon bags technique in Gizel sheep. Two fistulaed Gizel sheep with average BW 45±2 kg were used in a complete randomized design. The treatments were as following; A: canola meal, B: canola meal treated with 0.5% urea, C: canola meal treated with microwave. The ruminal dry matter and crude protein disappearance were measured at 0, 2, 4, 6, 8, 12, 16, 36 and 48 h. At 48 hours of incubation, ruminal degradability of canola meal treated with microwave was more than other treatments and this was indicative of the significant effect of processing in the increase in protein degradation and metabolizable protein in feed. Canola meal treated with microwave (167.16 g/kg DM) and canola meal (137.31 g/kg DM) had the highest and lowest effective ruminal degradable protein, respectively. The subjects in this experiment, the metabolizable protein of canola meal treated with 0.5% urea (357.163 g/kg DM) accounted for the highest value than the other treatments. Results show that increased metabolizable protein by processing meals with urea and microwave.
