“…The undigested residue of NSECM was fermented less extensively than the undigested residue of SBM as evidenced by less total gas and VFA production and IVFDM for the NSECM compared with SBM. Fibre present in cotyledons of canola and soybean seeds is rich in non-cellulosic non-starch polysaccharides such as pectin, whereas fibre present in the hulls of canola and soybean seeds is rich in cellulose that is more lignified than fibre present in the cotyledons (Bell, 1993;Karr-Lilienthal et al, 2005). Thus, fibre of dehulled SBM contains less cellulose and is less lignified than that of the canola co-products, because canola co-products are not dehulled.…”

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.

“…La canola o colza se desarrolló a partir de la colza (Brassica napus y Brassica campestris/ rapa) con el fin de obtener menores niveles de ácido eurúcico (<2%) en la porción aceitosa y bajos niveles de glucosinolatos (<30µmol-g -1 ) en la porción de la pasta (1). La torta de canola después de la extracción del aceite queda con un alto porcentaje de 35-40% de proteína cruda (2), la cual se caracteriza por tener un menor contenido de lisina y un mayor contenido de aminoácidos azufrados (metionina y cistina) que el de la torta de soya (3).…”

RESUMENObjetivo. Obtener los coeficientes de digestibilidad ileal aparente (CDIA) de proteína (PC) y aminoácidos (AA) de torta de canola, en lechones recién destetados. Materiales y métodos. Se utilizaron 24 lechones destetados a los 17 días de edad con un peso de 5.5 kg, a los cuales se les fijó una cánula simple en "T" en el ileon distal. Los lechones recibieron uno de los siguientes tratamientos: Dieta de Referencia (C) elaborada con caseína y almidón de maíz; dietas CTC (caseína-10% de Torta de canola) y CTCP (caseína-10% de torta de canola peletizada). Resultados. Los CDIA de PC y AA de la dieta C fueron superiores (p<0.05), con excepción de algunos aminoácidos de CTCP que tuvieron CDIA similares (p>0.05) a C. No se observó un efecto (p>0.05) del periodo (tiempo posdestete) sobre los CDIA de la PC y AA, exceptuando al aminoácido metionina. Los CDIA del nitrógeno (N) y AA de TCP fueron mayores (p<0.05) que los de TC. Conclusiones. La TCP puede ser incluida en dietas de lechones en un 10% empleando los coeficientes reportados en este trabajo.Palabras clave: Lechones, canola, aminoácidos, digestibilidad ileal. ABSTRACTObjective.

“…The indigestible carbohydrate content of CM is high (Kocher et al, 2000). Bell (1993) reported that CM has an average 2.5% -galacto-oligosaccharides and 18% nonstarch polysaccharides (NSP) of which 1.5% is soluble. The soluble NSP tends to increase the digesta viscosity and reduce nitrogen digestion and absorption (Annison, 1991), subsequently resulting in poor growth performance.…”

“…Canola is a particular type of genetically altered rapeseed with <2% erucic acid and <30 µm/g glucosinolate in air-dried oil-free meal (Bell, 1993). Canola meal (CM) is a by-product of canola seed-crushing after oil extraction process and contains high protein (40%) with a well-balanced amino acid (AA) composition (Newkirk, 2009).…”

The aim of the current study was to investigate the potential of Lactobacillus salivarius solid state fermentation for reduction of glucosinolate content in canola meal (CM) as well as the improvement of its nutrient digestibility for broiler chickens. Canola meal was treated with the L. salivarius in solid state fermentation for 30 days. Nutrients ileal digestibility was tested using 42-day-old broilers fed by either CM or fermented CM (FCM) as the sole source of energy and protein. The results showed that fermentation of CM using L. salivarius reduced glucosinolate content of CM by 38%. The digestibility coefficient was improved significantly for crude protein, Met, Cys, Arg, Asp, Glu, and Ser in FCM compared to CM. However, apparent metabolisable energy of CM was not affected by fermentation. It appears that fermentation treatment of CM using L. salivarius may improve the overall nutritive value of CM for broiler chickens, reducing its total glucosinolate and crude fibre content by 38 and 16%, respectively.
