Zhou, X., Young, M. G., Zamora, V., Zijlstra, R. T. and Beltranena, E. 2014. Feeding increasing dietary inclusions of extruded Brassica juncea canola expeller-pressed cake on growth performance, carcass characteristics, and jowl fatty acids of growing-finishing pigs. Can. J. Anim. Sci. 94: 331–342. The energy value of canola meal is considered low because of its relatively higher fibre and depleted oil content. Brassica juncea is a novel canola species with thinner seed coat and reduced fibre, but twice the glucosinolate content of B. napus. Remaining oil in canola cake provides greater dietary energy compared with solvent-extracted meal. Extrusion prior to expeller pressing may increase fat and protein digestibility and decrease the antinutritive effects of glucosinolates. A total of 880 pigs (38 kg), housed in 40 pens by sex, were fed 0, 5, 10, 15, or 20% extruded B. juncea expeller-pressed cake (EPC) to slaughter weight (120 kg) to evaluate the effects on growth performance, dressing, carcass traits, and jowl fatty acids. Diets provided 9.6 MJ net energy (NE) and 1.0, 0.9, 0.8, 0.7, and 0.7 g standardized ileal digestible Lys:MJ NE over five growth phases (days 0–14, 15–35, 36–56, 57–74, day 75 to slaughter weight). Each 5% EPC inclusion linearly decreased (P<0.05) feed disappearance (ADFI) by 46 g and weight gain (ADG) by 8 g, but did not affect gain:feed. Each 5% EPC inclusion linearly decreased (P<0.01) carcass weight by 440 g, loin depth by 0.6 mm, and increased days on test by 0.43, but did not affect dressing, backfat thickness, lean yield, or carcass index. Each 5% EPC inclusion linearly increased (P<0.001) mono- and polyunsaturated fatty acid content and iodine value by 0.8, 1.0 and 1.4 g 100 g−1of jowl fat, respectively. In conclusion, increasing dietary EPC inclusions decreased ADFI, ADG, carcass weight, and loin depth, and increased jowl fat unsaturation. We attributed much of the decrease in feed intake to greater 3-butenyl (9.7 µmol g−1) content in extruded B. juncea canola expeller-pressed cake, a glucosinolate more bitter than others in conventional canola.

Seed of Brassica napus canola (cv. AC Excel), B. rapa canola (cv. AC Parkland), and B. juncea canola (line J90-4253) was oil-extracted in a prepress solvent pilot plant. The three canola meals and soybean meal (SBM) (commercial) were fed in four replicates of a digestibility trial to evaluate their digestibility. The meals were mixed with a nutritionally adequate barley-wheat-SBM basal diet at levels of 15 and 30%. Chromic oxide (Cr2O3) was included at 0.5% of the diet as a chemical marker. Eighteen hybrid gilts, approximately 90 kg, were randomized to the first two replicates involving nine diets, including the basal diet, and this allotment was repeated. Brassica juncea meal (air-dry) contained 43.85% crude protein of 82% digestibility and 18.33 MJ kg−1 of gross energy of 71% digestibility. The corresponding values for B. napus AC Excel meal were 41.78, 81, 18.64 and 64; for B. rapa AC Parkland meal 40.05, 79, 18.45 and 71, and for SBM 45.10, 88, 17.28 and 82. Digestible energy values were: B. juncea 13.9, B. napus 13.0, B. rapa 14.1 and SBM 15.9 MJ kg−1. Key words: Canola meal, B. juncea meal, composition, digestibility, pigs

The aim of this study was to determine the optimal fungal culture to increase the nutritional value of canola meal so it could be used at higher feed inclusion rates, and for a broad range of monogastrics, including fish. Submerged incubation conditions were used to evaluate the performance of seven fungal cultures in hexane extracted (HE) and cold pressed (CP) canola meal. Aureobasidium pullulans (Y-2311-1), Fusarium venenatum and Trichoderma reesei resulted in the greatest improvements in protein levels in HE canola meal, at 21.0, 23.8, and 34.8 %, respectively. These fungi reduced total glucosinolates (GLS) content to 2.7, 7.4, and 4.9 μM.g-1, respectively, while residual sugar levels ranged from 0.8 to 1.6 % (w/w). In trials with CP canola meal, the same three fungi increased protein levels by 24.6, 35.2, and 37.3 %, and final GLS levels to 6.5, 4.0, and 4.7 μM.g-1, respectively. Additionally, residual sugar levels were reduced to 0.3-1.0 % (w/w).
