Effective use of novel canola feed ingredients

加拿大种植的油菜籽每年为加拿大经济贡献267亿美元。其目前的产量约为每年2100万吨油菜籽，预计到2025年将增加到每年2600万吨。随着对油菜籽需求的持续增长，重点从传统的压榨转向增值加工和特种产品生产，包括：1)油菜籽蛋白浓缩物（CPC）及其副产品，以及2)含有不同数量的蛋白质、油和抗营养因子的压榨/冷榨油菜籽（EPC）。为了从这些产品中获得最大的价值，必须向饲料工业展示它们作为饲料原料的天然优势。因此，本研究的目的是：1)开发CPC和EPC产品的全面营养概况，以确定其最佳应用，并优化家禽和猪日粮中的营养利用率；2)利用酶技术促进营养（油，氨基酸，磷）的利用；3)建立家禽和猪的标准化回肠可消化氨基酸和代谢能含量的预测方程。4)开发CPC， EPC及其副产品的近红外光谱（NIRS）校准。将建立一个关于化学和营养概况的综合数据库，并用于促进这些重要的加拿大饲料资源在动物营养方面的有效利用。这将允许在动物和家禽饲料中以更高的比例加入更高质量的膳食。这些新的发展将使CPC的制造商Botaneco受益，并且符合该项目的行业合作伙伴SaskCanola的授权。这项研究的结果也将促进更可靠地使用近红外光谱，这是行业合作伙伴加拿大Lumex仪器公司的一项资产。此外，由工业合作伙伴加拿大生物系统公司提供的酶的未来应用将降低生产者的投入成本，减少氮和磷在环境中的损失。

Canadian-grown canola contributes $26.7 billion to the Canadian economy each year. Its current production sits at approximately 21 million tonnes of canola seed per year and is expected to increase to 26 million tonnes per year by 2025. As the demand for canola continues to grow, the focus shifts from conventional crushing to value-added processing and specialty-product production, including: 1) Canola protein concentrates (CPC) and their co-products, and 2) Expeller/cold-pressed canola (EPC) containing variable amounts of protein, oil, and antinutritional factors. In order to derive the maximum value from such products, their natural advantage as feed ingredients must be presented to the feed industry. Therefore, the objectives of this research are: 1) To develop a thorough nutrient profile of the CPC and EPC products in order to identify their best possible applications and to optimize nutrient utilization in formulating poultry and swine diets, 2) To use enzyme technology to facilitate nutrient (oil, amino acids, phosphorus) utilization, 3) To develop prediction equations for standardized ileal digestible amino acids and metabolisable energy contents for poultry and swine, and 4) To develop near-infrared spectroscopy (NIRS) calibrations for CPC, EPC and co-products. A comprehensive database on the chemical and nutritional profiles will be generated and used to promote the effective use of these important Canadian feed resources in animal nutrition. This would allow the inclusion of higher quality meals at higher rates in animal and poultry feeds. Such new developments would benefit Botaneco, the manufacturer of CPC, and would be in line with the mandate of SaskCanola, the industry partners on this project. The outcomes of this research would also facilitate more reliable use of NIRS, an asset to the industry partner Lumex Instruments Canada. As well, future application of enzymes, supplied by industry partner Canadian Bio-Systems, would reduce input costs for producers and nitrogen and phosphorus losses into the environment.
