Background
The Feeds Regulations, 2024 require a proponent to submit a pre-market application for new feed ingredients or SIFs that have been modified such that they differ from an approved SIF or SIFs that are for a new purpose. We evaluate the information in the application to establish that the SIF is safe, effective and labelled correctly.
Approved SIFs are listed and described in the Canadian Feed Ingredients Table (CFIT), which is incorporated by reference (IBR) into the Feeds Regulations, 2024. Our Incorporation by Reference Policy requires that a consultation be conducted before changes to IBR documents are made. Refer to Documents incorporated by reference under the Feeds Regulations, 2024 for additional information.
Reclassified and amended SIF descriptions
Our Animal Feed Program (AFP) has identified that fresh liquid whey has been classified incorrectly in the CFIT. Currently, this SIF is classified and listed in subclass 3.1.3 (Protein products and by-products of animal origin – Dairy) in class 3 (Protein feeds), indicating that it was assessed and approved as a source of protein in livestock feeds. However, this SIF was assessed and approved as a source of energy.
We intend to reclassify fresh liquid whey and move this SIF to subclass 2.7 (Sugars and starches) in class 2 (Energy feeds) of part 1 of the CFIT. No other changes are being made to this description.
The ingredient number will be amended to reflect that the SIF has been moved from subclass 3.1.3 (Protein products and by-products of animal origin – Dairy) to subclass 2.7 (Sugars and starches) in part 1 of the CFIT. This is a reclassification an existing SIF description.
In addition, we have identified some errors that were made when transferring the SIF descriptions from Schedules IV and V of the Feeds Regulations, 1983 to the CFIT of the Feeds Regulations, 2024.
The units for the required label guarantee for iodine in the calcium iodate (1-503-007) description in the CFIT is milligrams per kilogram. The correct units are to be expressed as a percentage which aligns with the units found in this SIF definition in Schedule IV and other iodate descriptions found in the Schedules and the CFIT.
We intend to amend the existing SIF description for calcium iodate under subclass 5.3 (Minerals) of class 5 (Nutritional ingredients) in part 1 of the CFIT. The amended description will contain the correct units for the required label guarantee for iodine.
The amended description is:
Calcium iodate
is the anhydrous calcium salt of iodic acid, generally expressed as Ca(IO3)2 and having the CAS# 7789-80-2.
It shall be labelled with a guarantee for minimum percent iodine.
The standardized statement for the allowance of a preservative is not found in the hydrolyzed chicken feathers and blood meal (1-301-011) description in the CFIT. This statement was part of the SIF definition in Schedule IV, but was not included in the description found in the CFIT.
We intend to amend the existing SIF description for hydrolyzed chicken feathers and blood meal under subclass 3.1.1 (Protein products and by-products of animal origin – Terrestrial animals) of class 3 (Protein feeds) in part 1 of the CFIT. The amended description includes the standardized statement for the allowance of preservatives.
The amended description is:
Hydrolyzed chicken feathers and blood meal

To be stored in a sealed container after opening. / Ne pas entreposer les aliments pour le bétail qui ont été traités avec l'oxyde de calcium près de matériaux combustibles. Ne pas permettre l'oxyde de calcium d'entrer en contact avec des matériaux incompatibles (par exemple, des acides, des matières oxydantes et des composés réactifs halogénés). Conserver dans un contenant scellé après l'ouverture."
To address worker safety concerns, it shall be labelled with the following statement:
"When calcium oxide is added to water, calcium hydroxide is formed and an exothermic chemical reaction occurs, causing heat to be released. / Lorsque l'oxyde de calcium est ajouté à l'eau, l'hydroxyde de calcium se forme, ce qui produit une réaction exothermique qui libère la chaleur."
It shall be labelled with guarantees for minimum percent calcium and maximum milligrams of fluorine per kilogram.
Additional information
Transfer errors
We have identified that the existing description for fresh liquid whey had been classified incorrectly in the CFIT. Fresh liquid whey was assessed and approved as a source of energy and was not approved as a source of protein (or a dominant source of protein in livestock feeds). In addition, this SIF was listed as an energy source in Schedule IV of the Feeds Regulations, 1983 and therefore, suggests that when the SIF descriptions were being transferred from the Schedules to the CFIT it was not placed into the correct subclass/class of the CFIT. Therefore, this SIF will be moved to subclass 2.7 (Sugars and starches) of class 2 (Energy feeds) in part 1 of the CFIT.
We also have identified that the units for the label guarantee for iodine in the calcium iodate description were incorrect. The correct unit is a minimum percent of iodine and not expressed on a milligrams per kilogram basis. The correct units (that is, a percent) are found in the definition in Schedule IV of the Feeds Regulations, 1983, but there was a transfer error when this SIF was added to the CFIT and the incorrect units were included in this description.
In addition, the alternative names for certain fermentation products non-viable descriptions (Trichoderma longibrachiatum fermentation extract condensed, Trichoderma longibrachiatum fermentation extract dehydrated, Trichoderma longibrachiatum fermentation solubles dehydrated and Trichoderma longibrachiatum fermentation solubles condensed) were not transferred from Schedules IV and V to the CFIT. The alternative names found in the definitions of Schedules will be included in these descriptions found in the CFIT as this was a transfer error and will be corrected by adding these alternative names to corresponding descriptions in the CFIT.
Adding alternative names
We have identified that some SIF descriptions should include additional alternative names, either providing a more common name (for example, adding camelina meal as an alternative name to the camelina meal mechanical extracted description) to the list of approved SIF names or including alternative names that align with the common names used in food industry and found on food labels (that is, certain dairy products and by-products). The addition of these alternative names for certain dairy products and by-products descriptions found in the CFIT will align with the names used by the food industry and found on food labels for the same ingredients used in both the livestock feed industry and food industry in Canada.
Minor updates
We have identified that warning statement found in the calcium oxide description should be a caution statement and labelled as such. This statement relates to the safe handling and storage of the SIF as opposed to human health hazards and therefore better aligns with the definition of a caution statement in the Feeds Regulations, 2024 as opposed to the definition for a warning statement. The "warning/mise en garde" header will be removed and replaced with the "caution/précaution" header in the description.
