Rojo GA, Perez MVG, Bayardo UA, Correa CHJ, Cuaron IJA. Tec Pecu Mex 2001,39(3)179-192. Two experiments were conducted to evaluate the substitution of Soybean meal for Canola meal in diets for finishing pigs. In Exp 1, 28 pigs individually housed (initial weight, 63±9.1 kg) were used. Canola meal was as such or pre-pelleted and the addition of a flavoring agent was tested. Treatments were: 1) A fortified sorghum-soybean meal diet, 2) Canola meal, 3) Canola meal plus flavoring agent, 4) Pre-pelleted canola meal, 5) As 4 plus flavoring agent added. Diets were similar in nutrient profile. In Exp 2, 93 pigs (average initial weight, 51±5 kg) were used. Individually housed pigs, were randomly allotted to five treatments: 1) A sorghum-soybean meal diet, 2) A 50 % substitution of the soy protein by canola, 3) As 2, but 100% substitution, 4) As 3, but feed formulation to total amino acids, 5) As 3, but ME was not corrected. No differences (P>0.10) were found in Exp 1, thus canola meal could totally replace soy protein in diets for finishing pigs, provided that diets are formulated to digestible amino acids. In Exp 2, dietary energy dilution by canola (treatment 5), resulted in greater (P 0.10), gain/feed was deteriorated (P 0.64), carcass primal and lean cuts were unaltered (P>0.19). It is concluded that canola meal can totally replace soybean meal, if feed formulation to satisfy digestible amino acids and ME of the diet is maintained.
