  This experiment was conducted to evaluate the effects of using canola meal and two levels of vegetable oil on performance, egg traits and blood biochemical parameters of laying hens in late laying period. In this experiment 216 of Hi line (W36) laying hens from 62 to 74 weeks of age were used in a (3 × 2) factorial pattern with 3 level of canola meal (10.12%, 15.18% and 20.24%) and 2 level of vegetable oil (2% and 4%). This experiment was conducted in a completely randomized design with 6 groups and 3 replicates (with 12 hens in each replicate). The experimental groups included: 1) diet with 6.93% of soybean meal, 10.12% of canola meal and 2% of vegetable oil, 2) diet with 8.58% of soybean meal, 10.12% of canola meal and 4% of vegetable oil, 3) diet with 3.19% of soybean 15.18% of canola and 2% of vegetable oil, 4) diet with 3.19% of soybean meal, 15.18% of canola meal and 4% of vegetable oil, 5) diet without soybean meal, 20.24% of canola meal and 2% of vegetable oil, 6) diet without soybean meal, 20.24% of canola meal and 4% of vegetable oil. The results showed that the replacement of soybean meal by canola meal except of egg weight did not have any significantly effects on performance, egg traits and blood biochemical parameters of laying hens (P>0.05). The highest egg weight (63.62g) was observed by using 15.18% of canola meal. Manuscript profile
