In Québec, corn and soybean meal are major ingredients of the pigs’ diet. However, dry pea and canola are two other interesting feeds. The growing performance and carcass and fat quality of pigs fed with or without supplements of canola seeds or dry pea, which replaced 60 kg/t or 250 kg/t, respectively, of a conventional diet of corn, soybean meal and fat have been compared. Also, the impact of these ingredients on feeding costs has been evaluated. Adding either canola seeds or dry peas did not change the zootechnical performances of the pigs. Whatever the diet, the results were similar for average daily gain, feed consumption and conversion, carcass composition (fat and muscle thickness, lipidic and proteic mass), slaughter data (lean meat yield, dressing percentage and hog value index) and water consumption. All pigs exhibited a back fat with an adequate consistency (>0,60) but a consistency index near the lower acceptable French standard. Between 26 and 109 kg of live weight, pigs fed a supplement of dry peas showed a 4,5% better feed conversion than with a supplement of canola seeds. In July 2004, adding canola seeds or dry peas allowed savings of 0,47$ and 2,22$ per head, respectively, due to the high price of soybean meal (494$/t). However, when the latter dropped to 250$/t in October 2004, these two ingredients increased the feeding cost. Grinding canola seeds requires a grinder in good condition, equipped with a small-meshed screen. One must also check the oil availability and energy value of canola seeds.
