“…One possibility is the higher fiber content in CM compared with SBM (NRC, 2012). In earlier studies, a lower pig growth rate with CM was observed compared with SBM, because levels of digestible Lys decreased as CM inclusion level increased in the diets (McIntosh et al, 1986;Baidoo et al, 1987;Bell et al, 1988). More recently, feeding trials with CM in grower pigs where the diets were balanced to the same levels of apparent ileal di-gestible Lys resulted in growth rates equivalent to SBM, even at very high inclusion levels of CM in the diets (Mullan et al, 2000;Raj et al, 2000).…”

Two experiments using soybean meal (SBM) or canola meal (CM) were conducted to investigate whether the choice of digestibility marker influenced the apparent ileal digestibility (AID) or standardized ileal digestibility (SID) of N and AA in diets supplemented with phytase. In each experiment, 18 barrows fitted with T-cannulas at the ileocecal junction were assigned to 3 diets consisting of a N-free diet to determine endogenous losses of N and AA, a semipurified diet (SBM in Exp. 1 or CM in Exp. 2), and the semipurified diet supplemented with phytase at 1,000 phytase units/kg. Three digestibility markers including acid-insoluble ash (AIA), chromic oxide (Cr2O3), and titanium dioxide (TiO2) were added to each diet at 3 g/kg. Each diet was fed for 7 d, consisting of a 5-d adjustment and a 2-d collection of ileal digesta. In both studies, basal ileal endogenous losses determined with Cr2O3 as a digestibility marker were lower (P<0.01) than with those determined with AIA or TiO2 digestibility markers. Using SBM as the protein source in Exp. 1, there was no interaction between phytase and digestibility marker on AID or SID of AA. The AID of N and AA in SBM using AIA as a digestibility marker tended to be lower (P<0.1) compared with Cr2O3 or TiO2 digestibility markers. Phytase supplementation increased (P<0.001) the AID of Ca and P. The use of AIA or Cr2O3 digestibility marker tended to be associated with lower (P<0.1) SID values compared with TiO2. Phytase did not affect the SID of N or any AA in SBM except for Met, for which there was an increase (P<0.05) with phytase supplementation. Using CM as the protein source in Exp. 2, there were significant interactions between digestibility marker and phytase. Phytase supplementation had effects (P<0.01) on AID or SID when Cr2O3 or TiO2 was used as the digestibility marker. With Cr2O3 or TiO2 as the digestibility marker in the CM diets, phytase supplementation increased (P<0.05) the SID of N and all AA (except Trp). There was no SID of N or AA response to phytase supplementation of CM when AIA was used as a digestibility marker. In contrast, there were no clear improvements in AA digestibility from phytase supplementation for SBM. Phytase effects on AID or SID of AA were dependent on the digestibility marker used in diets when CM was used as the protein source but not when SBM was used as the protein source. Therefore, AA digestibility response to phytase supplementation may depend on the protein being evaluated as well as the choice of digestibility marker.

“…The nutritional value of toasted canola meal has been evaluated many times for pigs and the vast majority of the published information indicates that best results are obtained if canola meal supplies only one half of the supplementary protein in diets fed to growing pigs while it can be used to completely replace all of the supplementary protein supplied by soybean meal in diets fed to finishing pigs, (Baidoo et al 1987;Bell et al 1988;Thacker 1990). The results of the current experiment confirm these findings as complete replacement of the supplementary protein supplied by soybean meal with toasted canola meal reduced weight gain and feed conversion during the growing period (28.7-66.8 kg), while during the finishing period, complete replacement did not adversely affect feed intake, growth rate, feed conversion or carcass quality.…”

“…Many studies have been conducted in an attempt to develop techniques to improve the nutritive value of canola meal for growing pigs including supplementation with lysine (Bell et al 1988), iodine (Schone et al 1997) and enzymes (Thacker 2001) as well as dehulling (de Lange et al 1998), water extraction (Lui et al 1994) and various other technological treatments (Bourdon and Aumaitre 1990). Application of these techniques has generated varying degrees of success.…”

“…Unfortunately, performance commonly declines when canola meal completely replaces soybean meal in diets fed to growing-finishing pigs (Baidoo et al 1987;Bell et al 1988;Thacker 2001) and therefore research continues to be directed towards the development of methods to improve the nutritional value of canola meal for swine (Bell 1993;Schone et al 1997;Thacker 2001).…”

Thacker, P. A. and Newkirk, R. W. 2005. Performance of growing-finishing pigs fed barley-based diets containing toasted or non-toasted canola meal. Can. J. Anim. Sci. 85: 53-59. Eighty crossbred pigs (28.7 ± 3.9 kg BW) were assigned to one of five dietary treatments in a factorial design experiment (sex × treatment). The control diet was formulated using barley and soybean meal, while four experimental diets were formulated with either toasted or non-toasted canola meal replacing either half or all of the soybean meal in the test diets. The total glucosinolate content of the non-toasted meal was more than 15-fold higher than the toasted meal (1.01 vs. 15.58 µmol g -1 ). The principal glucosinolates in the non-toasted meal were 3-butenyl (3.05 µmol g -1 ), 2-OH-3-butenyl (5.47 µmol g -1 ) and 4-OH-3-methylindoyl (4.68 µmol g -1 ). Digestibility coefficients for dry matter, crude protein, and gross energy were significantly (P < 0.05) lower for the toasted and non-toasted canola meal diets compared with the soybean meal diet. There were no significant differences (P > 0.05) in digestibility coefficients between the two canola meals. Digestibility coefficients were higher (P < 0.05) for pigs fed the diets in which canola meal supplied only 50% of the supplementary protein compared with diets in which 100% of the supplementary protein was supplied by canola meal. Pigs fed toasted canola meal had similar weight gain, feed intake and feed conversion (P > 0.05) as pigs fed soybean meal while pigs fed non-toasted canola meal had lower weight gain and feed intake (P < 0.05) than pigs fed soybean meal. Feed conversion was unaffected by dietary treatment (P > 0.05). There were no significant effects (P < 0.05) due to diet on any carcass trait. The overall results of this experiment indicate that omitting the desolventization/toasting procedure from the process involved in the production of canola meal did not result in an improvement in the performance of pigs fed diets containing canola meal.Key words: Pigs, canola meal, performance, digestibility, carcass, toasting Thacker, P. A. et Newkirk, R. W. 2005. Performance des porcs de croissance-finition nourris d'orge enrichie de tourteau de canola grillé ou pas. Can. J. Anim. Sci. 85: 53-59. Quatre-vingts porcs hybrides (28,7 ± 3,9 kg de poids corporel) ont été répar-tis entre cinq régimes alimentaires dans le cadre d'une expérience factorielle (sexe × régime). La ration témoin contenait de l'orge et du tourteau de soja alors que dans les quatre rations expérimentales, le tourteau de canola grillé ou pas remplaçait la moitié ou la totalité du soja. Le tourteau de canola non grillé renfermait au-delà de 15 fois plus de glucosinolates que le tourteau grillé (1,01 c. 15,58 µmol g -1 ). Le tourteau non grillé contenait surtout du 3-butényle (3,05 µmol g -1 ), du 2-OH-3-butényle (5,47 µmol g -1 ) et du 4-OH-3-méthylindoyle (4,68 µmol g -1 ). Les coefficients de digestibilité de la matière sèche, des protéines brutes et de l'én-ergie brute étaient significativement (P < 0,05) plus ...
