The current interest in hemp is not limited to the medicinal use for humans, it is also gaining attention as a valuable feed ingredient for animals. For instance, the processing of whole hemp seed (HS) for the extraction of the oil can result in various feed materials for animals, including HS hulls, dehulled HS, HS oil, and HS cake/meal. However, currently, HS-derived products are not approved as feed ingredients in Canada, in part, because the safety and efficacy of these derivatives, like other jurisdictions, require certification by regulatory bodies for their use in animal feeds. In this context, this document reviews previous studies testing the application of hemp-derived products in various animal feeds, including poultry, swine, ruminants, as well as in aquaculture production to support their safety and efficacy. Furthermore, the document attempts to review available data on the transfer of delta-9-tetrahydrocannabinol (THC; the psychoactive component) into animal products. Hence, the aim of this work is to support future policy directions and guidelines for the application of various hemp-derived products in animal feeds.
