Red Dog Enterprises, Ltd. is a Manitoba-based company interested in promoting the use of Red OsierDogwood (Cornussericea also known as Cornus stolonifera) extracts in animal feed due to their high content ofphenolic compounds and their antimicrobial, antioxidant and anti-inflammatory characteristics. The Red OsierDogwood extract has been obtained, however, the extraction method has not been optimized to ensure thatmaximum yield of phenolics in the extract is achieved. Moreover shelf-life properties have not been evaluatedfor the resultant powdered extracts. Red Dog Enterprises Ltd. will need this information in order to completethe registration of the product with Canadian Food Inspection Agency (CFIA) Feed Section before it can bemarketed worldwide. Optimization of phenolic levels and completion of shelf life studies by the University ofManitoba will enable registration of the product. It is anticipated that registration of the product will openopportunities for Red Dog Enterprises Ltd. to create jobs in production, harvesting and marketing of Red OsierDogwood extracts. Plans have already been drawn with an Italian company to provide Red Dog EnterprisesLtd. with a machine that will be modified at PAMI (Prairie Agricultural Machinery Institute) for harvesting ofthe plant. Red Dog Enterprises Ltd. already has patents in Canada, the USA and the EU. One Chinese companyhas also expressed interest in this product. Red Osier Dogwood powder extracts can potentially be used asingredients in both animal feed and human food once confirmation tests are done and registration is completed.

红狗企业有限公司是一家总部位于马尼托巴省的公司，由于红木提取物(Cornussericea又称Cornus stolonifera)含有高含量的酚类化合物以及抗菌、抗氧化和抗炎特性，因此有兴趣促进红木提取物在动物饲料中的使用。红木提取物已经得到，但提取方法并没有优化，以确保提取物中酚类物质的最大得率。此外，还没有对所得到的粉末状提取物的保质期特性进行评估。红狗企业有限公司需要这些信息才能完成产品在加拿大食品检验机构(CFIA)饲料部门的注册，然后才能在全球范围内销售。马尼托巴大学对酚类物质水平的优化和保质期研究的完成将使产品能够注册。预计该产品的注册将为红狗企业有限公司创造生产、收获和销售红木提取物的机会。一家意大利公司已经制定了向红狗企业有限公司提供服务的计划。用一台将在帕米(草原农业机械研究所)改装的机器来收获植物。红狗企业有限公司已在加拿大、美国和欧盟拥有专利。一家中国公司也表达了对这一产品的兴趣。一旦确认测试和注册完成，红豆杉粉末提取物可能会被用作动物饲料和人类食品的成分。
