The dramatic increase in bio-oil production, has resulted in millions of tonnes of different types of co-products (eg. canola pellets, cold-pressed cakes, extracted cold-pressed cakes, canola meal) from different bio-oil processing methods such as chemical extraction, cold processing, and combined cold pressing and chemical extraction. To date, little systematic study has been carried out to study structural, chemical and nutritive features in feedstock and co-products from bio-processing using advanced synchrotron and globar technology in relation to nutrient delivery and supply to animals. This research aims to reveal the molecular chemistry of intrinsic structures in both feedstock and co-products and to detect the sensitivity of feed intrinsic structure to bio-processing and processing-induced changes on nutrient supply and delivery to animals and study association of feed intrinsic molecular structure with nutrient supply and delivery from feedstocks and co-products from bio-oil processing. The proposed research program will be completed in three phases. In Phase I, we will determine chemical and nutrient profiles, digestible, metablizable and net energy values and reveal unique molecular structural features of the feedstocks and co-products from bio-oil processing. In Phase II, we will study N-to-energy synchronization and the impact of the bio-oil processing involving physical, chemical and heat treatments on N metabolism, accumulation and microbial protein synthesis. In Phase III, we will determine nutrient supply and delivery (truly absorbed nutrient supply, Feed Milk Value) from the feedstock and co-products from bio-oil processing to dairy cattle and study association of bio-oil processing induced molecular structure changes with nutrient supply and delivery. It is anticipated that the proposed program will provide with a greater understanding the structure-animal interface and advance our current and basic nutrition knowledge and benefit to bio-oil processing, feed and livestock industries.**

生物油产量的急剧增加，导致了数百万吨不同类型的副产品（如生物油）。低芥酸菜子颗粒、冷榨饼、提取的冷榨饼、低芥酸菜子粗粉）。迄今为止，很少有系统的研究已经进行了研究的结构，化学和营养特性的原料和副产品的生物加工使用先进的同步加速器和globar技术与营养输送和供应给动物。本研究旨在揭示饲料及其副产品内在结构的分子化学特征，检测饲料内在结构对生物加工的敏感性以及加工引起的对动物营养供给和输送的变化，并研究饲料内在分子结构与生物油加工的饲料及其副产品的营养供给和输送的关系。拟议的研究计划将分三个阶段完成。在第一阶段，我们将确定化学和营养成分，可消化，可代谢和净能量值，并揭示生物油加工的原料和副产品的独特分子结构特征。在第二阶段，我们将研究N-能量同步和生物油加工的影响，包括物理，化学和热处理对N代谢，积累和微生物蛋白质合成。 在第三阶段，我们将确定从生物油加工到奶牛的原料和副产品的营养供应和输送（真正吸收的营养供应，饲料乳价值），并研究生物油加工引起的分子结构变化与营养供应和输送的关系。预计拟议的计划将提供更好的理解结构-动物界面，并推进我们当前和基本的营养知识，并有利于生物油加工，饲料和畜牧业。
