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.

最近，加拿大蚕豆在加拿大西部的播种面积急剧增加。豆类生产商和畜牧业提出了以下关键问题：利用这些在加拿大西部种植的蚕豆饲料（干草和青贮饲料）和蚕豆的最佳喂养策略是什么？蚕豆草料干草和青贮的最佳采伐阶段是什么？(生长阶段1=盛花期vs.生长阶段2=中期灌罐（圆绿）vs.生长阶段3=后期灌罐（圆圆）？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渣）的喂养指南是什么？所有这些问题不仅对脉冲工业，而且对畜牧业和饲料工业都至关重要。不幸的是，在文献中几乎找不到关于加拿大西部的信息，特别是关于新开发的蚕豆品种/单宁水平为零/低和高的新品系。文献中没有对加拿大西部草原省份进行系统的研究。我们的脉搏和畜牧业生产者以及加拿大的相关产业迫切需要得到上述所有答案。本研究计划的目标是采用系统的方法研究在加拿大西部低热量单位气候条件下，新开发的品种/新品系、生长阶段（切割时间）、单宁水平和各种饲料加工技术对全作物蚕豆饲料（用于干草和青贮）和蚕豆（用于能量和蛋白质浓缩物）营养价值的影响，并为畜牧业开发利用全作物蚕豆干草的新饲养策略。蚕豆青贮和蚕豆作为能量和蛋白质浓缩物。本研究对我国蚕豆饲料和蚕豆的价值提取具有重要的参考价值，为我国农业和畜牧业带来最大的经济回报。
