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.

近年来，加拿大西部的蚕豆播种面积急剧增加。脉冲 生产者和畜牧业提出了以下关键问题：什么是最好的饲养策略， 这些蚕豆饲料（干草和青贮饲料）和蚕豆生长在加拿大西部？什么是最佳切割阶段 蚕豆草料干草和青贮饲料（生长阶段1=盛花期与生长阶段2=中盆填充（圆形 绿色）vs.生长阶段3=后期盆栽填充（全圆形）？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？什么是喂养 蚕豆或蚕豆饲料指南，包括放牧、干草、青贮饲料和收获后的作物残留物？所有这些 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，特别是对于 新开发的具有零/低和高单宁水平的蚕豆品种/新品系。没有系统的研究 在加拿大西部草原省份的文献中发现。迫切需要得到上述所有答案 为加拿大的豆类和牲畜生产商及相关行业提供服务。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， （刈割时间）、单宁水平和不同饲料加工工艺对整株蚕豆营养价值的影响 在加拿大西部种植的牧草（用于干草和青贮饲料）和蚕豆（用于能量和蛋白质浓缩物）， 低热单位气候条件，并开发新的饲养策略，畜牧业使用整个 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。预计这项研究将 从蚕豆饲料和蚕豆中提取价值，以最大限度地提高经济回报， 我们的脉搏和畜牧业。
