The growth in canola seeded acreage (>20 million acres in 2012) has facilitated the expansion of the Canadian canola crushing industry. For example in Saskatchewan alone, crushing capacity has grown to exceed 4.5 million tonnes generating in excess of 2.5 million tonnes of canola meal annually. As a result, the supply of canola meal has expanded greatly and finding new markets is becoming more important than ever for the canola sector. To this point, the vast majority of the research on canola meal in cattle diets has been with lactating dairy cattle. While this is an important market, in Canada it is limited in size due to the nature of the dairy industry. In contrast there has been limited work targeting the protein needs of growing cattle, specifically beef steers/heifers or growing replacement dairy heifers. Both are important potential markets. For example, there are approximately 444,000 dairy heifers in Canada while the beef sector consists of ~ 4.1 million beef cows and ~ 4 million calves annually. There is also in excess of 2.5 million head of cattle fed for slaughter annually. This project will attempt to establish canola meal as the preferred protein supplement for growing beef cattle and dairy heifers. In order to do so, it will compare performance and rumen fermentation and microbial protein flow in growing cattle relative to other commonly used protein sources. By doing so it will provide an alternative national market for canola meal that will help support canola meal pricing, benefiting both the canola processor and ultimately through higher prices and demand for canola meal, it will support higher prices for canola growers.

双低油菜籽播种面积的增长（2012 年超过 2000 万英亩）促进了加拿大双低油菜籽压榨行业的扩张。例如，仅在萨斯喀彻温省，压榨能力就已增长到超过 450 万吨，每年生产超过 250 万吨双低菜粕。因此，双低菜粕的供应量大幅增加，对于双低菜行业来说，寻找新市场变得比以往任何时候都更加重要。到目前为止，绝大多数关于牛日粮中双低菜粕的研究都是针对泌乳奶牛的。虽然这是一个重要的市场，但在加拿大，由于乳制品行业的性质，其规模有限。相比之下，针对生长牛的蛋白质需求的工作有限，特别是肉牛/小母牛或生长的替代奶牛。 两者都是重要的潜在市场。例如，加拿大每年约有 444,000 头奶牛，而牛肉行业则由约 410 万头肉牛和约 400 万头小牛组成。每年还有超过 250 万头牛被饲养用于屠宰。该项目将尝试将双低菜粕打造为生长肉牛和奶牛的首选蛋白质补充剂。为此，它将比较生长牛相对于其他常用蛋白质来源的性能、瘤胃发酵和微生物蛋白质流。通过这样做，它将为双低菜粕提供一个替代的全国市场，这将有助于支持双低菜粕定价，使双低菜粕加工商受益，并最终通过更高的价格和对双低菜粕的需求，支持双低菜粕种植者更高的价格。
