PSXIII-12 Characterization of Physiochemical and Nutrient Profiles of Feedstock and co-Products from Canola bio-oil Processing in Ruminants: Impacted by Source Origin

Abstract The objective of this study was to characterize physiochemical and nutrient profiles feedstock co-products from canola processing that were impacted by source origin compare feedstocks (mash pellet) five different bio-oil plants with batches samples in each plant Canada (CA) China (CH) collected the Canola Council (CCC). detailed physicochemical nutrients parameters for ruminants determined chemical composition, TDN truly digestible nutrients, energy profile (ME, NE), protein carbohydrate subfractions their degradation digestion dairy cows. data analyzed using Mixed model procedure SAS 9.4 RCBD. treatment differences compared Tukey method. results showed CP greater CH meals (P=0.003). EE not between CA (P >0.05). TDN1x similar regardless country had tdCP tdNDF than (P< 0.05), while tdNFC 0.05). values ME3x, NELp3x, NEm3x, NEg3x both countries No observed also pelleting affected fractionation soluble (PA2) slowly degradable fractions (PB2) fiber (CB2), (CB3), indigestible (CC) among presented water-soluble (CA4, P=0.04) less CB2 (P=0.01) CC 0.001) meals. Although seeds within counties, oil-extraction process seemed have generated some aspects on countries.
