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：什么是最好的喂养策略，利用这些蚕豆饲料（干草和青贮饲料）和蚕豆生长在加拿大西部？什么是蚕豆饲料干草和青贮饲料的最佳切割阶段（生长阶段1=盛花阶段vs.生长阶段2=中期盆栽填充（圆绿色）vs.生长阶段3=后期盆栽填充（全圆）？蚕豆饲料和蚕豆中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？什么是蚕豆或蚕豆饲料的喂养指南，包括放牧，干草，青贮饲料，收获后的作物残留物？所有这些设备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，在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还没有系统的研究。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找到上述所有答案。本研究计划的目的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，（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）生长在加拿大西部的低热单位气候条件下，并为畜牧业开发新的饲养策略，使用全作物蚕豆干草，作为能量和蛋白质浓缩物的蚕豆青贮饲料和蚕豆。期望本研究能对我国豆类产业的发展产生积极的影响，为我国豆类产业和畜牧业的经济效益最大化提供有益的借鉴。

Recently, Canadian faba bean seeded area has been dramatically increasing in western Canada. Pulseproducers and livestock industry raise following crucial questions: What is best feeding strategy of utilizingthese faba forage (hay and silage) and faba bean grown in western Canada? What is the best cutting stage forfaba forage hay and silage (Growth Stage 1= Full Flower Stage vs. Growth Stage 2= Mid Pot Filled (RoundGreen) vs. Growth Stage 3=Late Pot Filled (Full Round) ? Does tannin content in faba forage and faba beanmatter to ruminant livestock? If yes, what is an optimal level in faba forage and faba bean? What are feedingguidelines on faba bean or faba forage including grazing, hay, silage, and crop residue after harvest? All thesequestions 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 fornewly developed faba varieties/new lines with zero/low and high tannin levels. There is no systematic studyfound in literature for western Prairie Provinces in Canada. There is an urgent need to get all the above answersfor our pulse and livestock producers and related industries in Canada. The objectives of this research programare 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 fabaforage (for hay and silage) and faba bean (for energy and protein concentrate) grown in western Canada underlow heat unit climate condition and to develop new feeding strategies for livestock industry for using wholecrop faba hay, faba silage and faba bean as energy and protein concentrate. It is expected that the research willhighly benefit to our industries to extract value from faba forage and faba bean to maximize economic return toour pulse and livestock industry.
