“…Juncea canola meal The CP and NDF content of JSECM were similar to those reported by Landero et al (2013). The JSECM contained less fibre than NSECM because Juncea canola seed has a thinner seed coat than Napus canola seed (Slominski et al, 2012).…”

Canola co-products are sources of amino acid and energy in pig feeds, but their fermentation characteristics in the pig intestine are unknown. Thus, we determined the in vitro fermentation characteristics of the canola co-products Brassica juncea solvent-extracted canola meal (JSECM), Brassica napus solvent-extracted canola meal (NSECM), B. napus expeller-pressed canola meal (NEPCM) and B. napus cold-pressed canola cake (NCPCC) in comparison with soybean meal (SBM). Samples were hydrolysed in two steps using pepsin and pancreatin. Subsequently, residues were incubated in a buffer solution with fresh pig faeces as inocula for 72 h to measure gas production. Concentration of volatile fatty acids (VFA) per gram of dry matter (DM) of feedstuff was measured in fermented solutions. Apparent ileal digestibility (AID) and apparent hindgut fermentation (AHF) of gross energy (GE) for feedstuffs were obtained from pigs fed the same feedstuffs. On DM basis, SBM, JSECM, NSECM, NEPCM and NCPCC contained 15, 19, 22, 117 and 231 g/kg ether extract; and 85, 223, 306, 208 and 176 g/kg NDF, respectively. In vitro digestibility of DM (IVDDM) of SBM (82.3%) was greater ( P < 0.05) than that of JSECM (68.5%), NSECM (63.4%), NEPCM (67.5%) or NCPCC (69.8%). The JSECM had greater ( P < 0.05) IVDDM than NSECM. The IVDDM for NSECM was lower ( P < 0.05) than that for NEPCM, which was lower ( P < 0.05) than that for NCPCC. Similarly, AID of GE was greatest for SBM followed by NCPCC, JSECM, NEPCM and then NSECM. Total VFA production for SBM (0.73 mmol/g) was lower ( P < 0.05) than that of JSECM (1.38 mmol/g) or NSECM (1.05 mmol/g), but not different from that of NEPCM (0.80 mmol/g) and NCPCC (0.62 mmol/g). Total VFA production of JSECM was greater ( P < 0.05) than that of NSECM. Total VFA production of NSECM was greater ( P < 0.05) than that of NEPCM or NCPCC, which differed ( P < 0.05). The ranking of feedstuffs for total VFA production was similar to AHF of GE. In conclusion, in vitro fermentation characteristics of canola co-products and SBM simulated their fermentation in the small and large intestine of pigs, respectively. The 30% greater VFA production for JSECM than NSECM due to lower lignified fibre of JSECM indicates that fermentation characteristics differ between canola species. The NSECM had the highest fermentability followed by NEPCM and then NCPCC, indicating that fat in canola co-products can limit their fermentability in the hindgut.

“…However, lysine content was similar in the B. napus and B. juncea CM fed in this trial, whereas it is usually lower in B. juncea CM than B. napus CM (Bell et al, 1998;Le et al, 2012;Trindade Neto et al, 2012). The lysine content of B. juncea CM fed was higher than that observed by others (Collins et al, 2011;Landero et al, 2013;Le et al, 2014;Zhou et al, 2013Zhou et al, , 2014a.…”

“…However, the B. juncea CM fed in our trial (ADF content: 128.1 g/kg, NDF content: 215.6 g/kg) had 0.8, 2.2, and 1.6 g/kg lower ADF and 0.5, 0.9 and 1.4 g/kg lower NDF content than those reported by Bell et al (1998), Landero et al (2013) and Zhou et al (2013), respectively, but 1.1 and 4.3 g/kg greater ADF and NDF content, respectively, than those observed by Montoya and Leterme (2009).…”

“…The CP, crude fat and crude fibre content of B. napus and B. juncea CM fed in this trial were within the published range (Bell et al, 1998;King et al, 2001;Montoya and Leterme, 2009;Khajali and Slominski, 2012;Zhou et al, 2013;Landero et al, 2013). However, the B. juncea CM fed in our trial (ADF content: 128.1 g/kg, NDF content: 215.6 g/kg) had 0.8, 2.2, and 1.6 g/kg lower ADF and 0.5, 0.9 and 1.4 g/kg lower NDF content than those reported by Bell et al (1998), Landero et al (2013) and Zhou et al (2013), respectively, but 1.1 and 4.3 g/kg greater ADF and NDF content, respectively, than those observed by Montoya and Leterme (2009).…”

“…However, glucosinolate content of B. juncea is 2-3 times greater than that of B. napus CM. It contains more 3-butenyl (gluconapin), a glucosinolate with a more bitter taste than those in conventional CM (Bell et al, 1998;Landero et al, 2013). Therefore, the advantage of reduced fibre content may be compromised by decreased palatability of B. juncea CM.…”
