Develop new strategies to efficiently utilize faba forage hay, silage & faba bean in ruminant livestock systems to maximum economic return and benefit to prairie pulse growers

近年来，加拿大西部的蚕豆播种面积急剧增加。豆类生产者和畜牧业提出了以下关键问题：利用加拿大西部种植的这些蚕豆饲料（干草和青贮饲料）和蚕豆的最佳饲养策略是什么？** 蚕豆饲料干草和青贮饲料的最佳切割阶段是什么（生长阶段1=盛花期vs.生长阶段2=中期盆栽填充（圆形）** 绿色vs.生长阶段3=后期盆栽填充（圆形）？蚕豆饲料和蚕豆 ** 中的单宁含量对反刍家畜有影响吗？如果是，蚕豆饲料和蚕豆的最佳水平是多少？蚕豆或蚕豆饲料（包括牧草、干草、青贮饲料和收获后的作物残留物）的饲养指南是什么？所有这些问题不仅对豆类行业至关重要，而且对畜牧业和饲料行业也至关重要。不幸的是，在加拿大西部的文献中几乎找不到任何信息，特别是关于 ** 新开发的蚕豆品种/新品系的零/低和高单宁水平。在加拿大西部草原省份的文献中没有发现系统的研究。我们迫切需要为加拿大的豆类和畜牧业生产者以及相关行业获得上述所有答案。本研究计划的目标 ** 是使用系统的方法来调查最近开发的品种/新品系，生长阶段 ** 的影响。（切割时间），单宁水平，不同饲料加工工艺对全株蚕豆营养价值的影响（用于干草和青贮饲料）和蚕豆（用于能量和蛋白质浓缩物）在加拿大西部低热量单位气候条件下生长，并为畜牧业开发新的饲养策略，作物蚕豆干草、蚕豆青贮饲料和蚕豆作为能量和蛋白质浓缩物。期望本研究能为我国豆类产业的发展带来巨大的经济效益，从蚕豆饲料和蚕豆中提取价值，使我国豆类产业和畜牧业的经济效益最大化。

Recently, Canadian faba bean seeded area has been dramatically increasing in western Canada. Pulse**producers and livestock industry raise following crucial questions: What is best feeding strategy of utilizing**these faba forage (hay and silage) and faba bean grown in western Canada? What is the best cutting stage for**faba forage hay and silage (Growth Stage 1= Full Flower Stage vs. Growth Stage 2= Mid Pot Filled (Round**Green) vs. Growth Stage 3=Late Pot Filled (Full Round) ? Does tannin content in faba forage and faba bean**matter to ruminant livestock? If yes, what is an optimal level in faba forage and faba bean? What are feeding**guidelines on faba bean or faba forage including grazing, hay, silage, and crop residue after harvest? All these**questions are vital important to NOT ONLY pulse industry BUT ALSO livestock and feed industries.**Unfortunately there is little information that can be found in the literature, in western Canada, particularly for**newly developed faba varieties/new lines with zero/low and high tannin levels. There is no systematic study**found in literature for western Prairie Provinces in Canada. There is an urgent need to get all the above answers**for our pulse and livestock producers and related industries in Canada. The objectives of this research program**are to use a systematic approach to investigate effects of recently developed variety/new line, growth stage**(cutting time), tannin level, and various feed processing technology on nutritive values of whole crop faba**forage (for hay and silage) and faba bean (for energy and protein concentrate) grown in western Canada under**low heat unit climate condition and to develop new feeding strategies for livestock industry for using whole**crop faba hay, faba silage and faba bean as energy and protein concentrate. It is expected that the research will**highly benefit to our industries to extract value from faba forage and faba bean to maximize economic return to**our pulse and livestock industry.
