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。它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。随着对油菜籽的需求持续增长，重点从传统的压榨转向附加值加工和特种产品的生产，包括：1)油菜籽浓缩蛋白(CPC)及其副产品，以及2)脱脂/冷压油菜籽(EPC)，其中含有不同数量的蛋白质、油和抗营养因子。为了从这些产品中获得最大的价值，必须向饲料行业展示它们作为饲料原料的天然优势。因此，这项研究的目标是：1)建立完整的CPC和EPC产品的营养概况，以确定它们在配制家禽和猪日粮中的最佳应用和优化营养利用；2)利用酶技术促进养分(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；以及4)建立CPC、EPC和联合产品的近红外光谱(NIRS)校准。将建立一个关于化学和营养概况的综合数据库，并将其用于促进在动物营养方面有效利用这些重要的加拿大饲料资源。这将允许在动物和家禽饲料中以更高的比率添加更高质量的膳食。这样的新开发将使CPC的制造商Botaneco受益，并将符合该项目的行业合作伙伴SaskCanola的授权。这项研究的结果还将有助于更可靠地使用近红外光谱，这是行业合作伙伴Lumex仪器加拿大公司的一项资产。此外，行业合作伙伴加拿大生物系统公司提供的酶的未来应用将减少生产者的投入成本，并减少环境中的氮和磷损失。

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.
