The present feeding of barley grains to dairy and beef cattle is faced with increasing challenges in terms of animal production and health. The cost of barley grains is variable and has highly increased in recent times, threatening the economic competitiveness livestock production. Alternative of feed resources particularly oat grain with high nutritive value and low cost are required to improve Feed Milk Value (FMV) and improve feeding utilization efficiency for dairy cows. However, how much difference, variation, nutrient availability and internal structure impact between and within varieties and types of oat grain, is unknown. The objectives of this study are to use a systematic approach to develop alternative feeding strategies to more efficiently utilize both feed- and milling-type of oat grain grown in Prairie by integration with or maximum replacing barley in sustainable dairy production for improving animal production and health; To assist dairy industry to develop low-cost/alternative feeding strategies by utilizing alternative feed resources, and To increase economic returns to oat producers and its related industries. The proposed research program includes five projects. In Project 1, we will systematically compare varieties and types of oat grain with common barley to find best variety and type of oat grain with highest FMV for dairy cows. In project 2, we will improve/increase FMV for both feed- and milling type of oat grain through feed processing applications. In Projects 3 & 4, we will to develop alternative feeding strategies to find a maximum or optimal replacement level of barley grain with the feed- and milling-type of oat grain in high production lactation dairy cow. In Project 5, we will develop feeding strategy for both raw and heating-related processed feed-and milling Type of oat grain in high production lactation dairy cows. The final goals are to maximize benefit and economic return to prairie oat growers and advance our current knowledge by increasing and enhancing basic knowledge of the optimal nutrient supply to dairy cattle through oat variety and type selection, feed processing, and optimal feed ingredient blending. The info obtained from this research program will support sustainable development of feed and livestock industry in Canada.

目前将大麦谷物喂给乳制品和肉牛面临的面临着越来越多的动物生产和健康方面的挑战。大麦谷物的成本可变，并且最近有很大增加，从而威胁了经济竞争力的牲畜产量。饲料资源的替代品，尤其是具有高营养价值和低成本的燕麦谷物，以提高饲料牛奶价值（FMV）并提高奶牛的饲料利用效率。然而，尚不清楚差异，变化，养分的可用性和内部结构的影响和内部的燕麦谷物和类型之间的影响是未知的。这项研究的目标是使用系统的方法来制定替代喂养策略，以更有效地利用草原种植的燕麦谷物的饲料和铣削型，通过与可持续乳制品生产中的大麦相结合或最大取代大麦来改善动物生产和健康；通过利用替代饲料资源，并增加对燕麦生产商及其相关行业的经济回报，以协助乳制品行业制定低成本/替代饲养策略。拟议的研究计划包括五个项目。在项目1中，我们将系统地比较燕麦谷物的品种和类型的燕麦谷物，以查找最佳的燕麦谷物，奶牛FMV最高的燕麦谷物。在项目2中，我们将通过饲料处理应用改进/增加燕麦谷物的FMV。 在项目3和4中，我们将制定替代喂养策略，以在高生产哺乳期奶牛中使用燕麦谷物的饲料和铣削型的大麦谷物的最大或最佳替代策略。在项目5中，我们将在高生产哺乳奶牛中制定原始和与加热相关的加工饲料类型的喂食策略。最终的目标是通过通过燕麦品种和类型选择，饲料加工以及最佳的饲料成分混合物来提高和增强对奶牛的最佳养分供应的基本知识，从而最大程度地利用大草原燕麦种植者的利益和经济回报，并提高我们当前的知识。从该研究计划获得的信息将支持加拿大饲料和牲畜行业的可持续发展。
