Hemp as a Feed Ingredient Summary Whole hemp seed offers high protein and energy content, making it attractive from a feed formulation standpoint High levels of ALA offer potential for hemp seed and oil to be used for the production of omega-3 eggs and meat Challenge: – Hemp is not an approved feed ingredient in Canada 2011 CHTA National Hemp Convention

Excerpt from the Regulatory Guidance (RG-1) – Canadian Food Inspection Agency “In Canada, livestock feeds are regulated, as per the federal Feeds Act and Regulations, by the CFIA. All single ingredient feeds manufactured, sold or imported into Canada must be approved and listed in either Schedule IV or Schedule V of the Feeds Regulations. At the present time, hemp products are not approved as livestock feed ingredients in Canada. Each hemp product intended to be used as a livestock single ingredient feed (e.g., hemp meal, hemp oil, seeds) will require separate approval.”

Process for Registration of Hemp Seed Products Regulatory Guidance Process Administrative information – Labeling – Ingredient Description – Ingredient Composition – Manufacturing Process – Safety Data Requirements – Efficacy Data Requirements Minimum of 3 studies required

Towards Registration in Canada Safety and Efficacy Studies Funding from the following is committed to addressing the need for data: – Canadian Hemp Trade Alliance – Poultry Industry Council – Manitoba Innovation, Energy and Mines STIC Fund – Canadian Agriculture Adapation Program (AAFC) 2011 CHTA National Hemp Convention

Studies to Date 2011 CHTA National Hemp Convention

Study Design 48 Bovan hens – 19 weeks of age Housed in individual metabolism cages for 12 weeks Wheat/Barley/Soy-based diets – Formulated to meet hen requirements 48 Bovan hens (19 weeks) Hempseed oil (4, 8, 12%) Hempseed (10, 20%) Control

Study Design Measurements – Production – Egg quality – Fatty acid analysis – Indices of bird health and welfare – Sensory analysis of cooked eggs

Results – Hemp Seed (HS) 2011 CHTA National Hemp Convention

Results – Hemp Oil (HO) 2011 CHTA National Hemp Convention

Results Omega-3 Fatty Acids 2011 CHTA National Hemp Convention

Sensory Evaluation Sensory analysis conducted with trained panel – Cooked egg product – Attributes included aroma and flavour No significant differences on sensory parameters due to hemp inclusion 2011 CHTA National Hemp Convention

Next Steps Complete studies with laying hens Initiate and complete studies with broiler chickens Project completion: March 31, CHTA National Hemp Convention
