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.

目前用大麦谷物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。大麦谷物的成本变化很大，并且近年来大幅上涨，威胁到畜牧业生产的经济竞争力。需要替代饲料资源，特别是营养价值高、成本低的燕麦粒，以提高奶牛饲料乳值（FMV），提高饲料利用效率。然而，燕麦品种和类型之间和内部的差异、变异、养分利用率和内部结构影响有多大，目前尚不清楚。本研究的目的是使用系统方法开发替代饲养策略，通过在可持续乳制品生产中与大麦整合或最大限度地替代大麦，从而更有效地利用草原种植的饲料型和制粉型燕麦谷物，从而改善动物生产和健康;协助乳制品行业利用替代饲料资源制定低成本/替代饲料策略，并提高燕麦生产商及其相关行业的经济回报。拟议的研究计划包括五个项目。在项目一中，我们将系统地比较燕麦粒的品种和类型与普通大麦，以寻找奶牛FMV最高的最佳燕麦粒品种和类型。在项目 2 中，我们将通过饲料加工应用改善/提高饲料型和碾磨型燕麦粒的 FMV。 在项目 3 和 4 中，我们将开发替代饲养策略，以找到高产泌乳奶牛中大麦谷物与饲料和研磨型燕麦谷物的最大或最佳替代水平。在项目 5 中，我们将为高产泌乳奶牛的生饲料和加热相关的加工饲料以及磨粉型燕麦谷物制定饲养策略。最终目标是最大限度地提高草原燕麦种植者的利益和经济回报，并通过燕麦品种和类型选择、饲料加工和最佳饲料成分混合来增加和增强奶牛最佳营养供应的基础知识，从而提高我们现有的知识。从该研究项目中获得的信息将支持加拿大饲料和畜牧业的可持续发展。
