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.

目前用大麦颗粒喂养奶牛和肉牛在动物生产和健康方面面临着越来越多的挑战。大麦谷物的成本是可变的，近年来大幅增加，威胁到畜牧业生产的经济竞争力。为了提高奶牛的饲料乳值（FMV），提高奶牛的饲料利用效率，需要替代营养价值高、成本低的饲料资源，特别是燕麦粒。然而，燕麦籽粒的品种和类型之间以及品种和类型内部的差异、变异、养分有效性和内部结构影响有多大尚不清楚。本研究的目的是使用一种系统的方法来开发替代饲养策略，以更有效地利用饲料和碾磨型燕麦谷物种植在草原通过整合或最大限度地取代大麦在可持续的乳制品生产，以提高动物生产和健康;为了帮助乳品业通过利用替代饲料资源开发低成本/替代饲养策略，提高燕麦生产者及其相关产业的经济效益。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和普通大麦的品种和类型，以找到奶牛FMV最高的燕麦谷物的最佳品种和类型。在项目2中，我们将通过饲料加工应用提高/增加饲料和研磨类型燕麦谷物的FMV。 在项目3和4中，我们将开发替代喂养策略，以找到高产泌乳奶牛中用饲料和研磨型燕麦谷物替代大麦谷物的最大或最佳水平。在项目5中，我们将为高产泌乳奶牛开发生食和加热相关加工饲料以及研磨型燕麦谷物的饲喂策略。最终的目标是最大限度地提高收益和经济回报，以草原燕麦种植者和推进我们目前的知识，通过增加和加强最佳营养供应的基础知识，以奶牛燕麦品种和类型的选择，饲料加工，最佳饲料成分混合。从这项研究计划中获得的信息将支持加拿大饲料和畜牧业的可持续发展。
