On a molecular basis, study association of feed intrinsic molecular structure with nutrient supply and delivery in animals from feedstocks and co-products from bio-oil processing

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(例如。从化学提取、冷加工、冷榨和化学提取相结合的不同生物油加工方法中提取的菜籽油颗粒、冷榨糕点、榨制冷榨糕点、菜籽粕)。到目前为止，利用先进的同步加速器和GLOBAR技术对利用先进的同步加速器和GLOBAR技术进行生物加工的原料和副产品中的结构、化学和营养特征进行的系统研究与动物的营养输送和供应有关。本研究旨在揭示饲料原料和副产物的内在结构的分子化学，检测饲料内在结构对生物加工和加工引起的动物营养供应和输送变化的敏感性，并研究饲料内在分子结构与原料和生物油加工副产物的营养供应和输送的关系。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概况、可消化、可代谢和净能值，并揭示生物油加工原料和副产品的独特分子结构特征。在第二阶段，我们将研究氮与能量的同步以及生物油加工过程中物理、化学和热处理对氮的代谢、积累和微生物蛋白质合成的影响。在第三阶段，我们将确定生物油加工的饲料和副产品对奶牛的养分供应和输送(真正吸收的养分供应量，饲料乳价)，并研究生物油加工引起的分子结构变化与养分供应和输送的关系。预计拟议的计划将使我们对结构-动物界面有更多的了解，并促进我们目前和基本的营养知识，并为生物油加工、饲料和畜牧业带来好处。

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.
