4.1 Labelling of Livestock Feed

According to Section 26 of the Feeds Regulations all livestock feed (bagged or bulk) manufactured, sold or imported must be properly labelled. In the case of bulk feed it should be emphasized that a label must accompany the shipment.

The CFIA has exempted most categories of livestock feed from presale evaluation and registration. As a result of this, the responsibility for labelling of livestock feeds rests with the feed manufacturer.

CFIA inspectors routinely visit feed mills and verify labels for compliance with feed labelling standards. In this regard, particular attention is paid to the labelling of medicated feeds. Mislabelled medicated feed can adversely affect livestock health and livestock production, and lead to drug residues. Label violations for medicated products are considered serious and unacceptable.

This section provides a regulatory overview of the labelling of feed, set up as a series of commonly encountered labels. It should be emphasized that this is just an overview; to ensure compliance with prescribed labelling standards, you must obtain a copy of the Feeds Act, the Feeds Regulations, and the "Compendium of Medicating Ingredient Brochures", 8th Edition. These documents are available on the main Livestock Feeds web page.

4.2 Liquid Feed Standards

Liquid feeds require additional labelling statements, compared to dry feeds. The additional information required on labels for liquid feeds is as follows:

  1. The label for a liquid feed shall contain a weight per unit volume statement. The reference point temperature for the volumetric measurement is 20°C (i.e., "Density at 20°C = space kg/L").
  2. Liquid feeds containing ingredients which do not stay in suspension for up to 60 days shall have on their labels the following statement: "This product must be agitated while being dispensed or fed."
  3. The label of a liquid feed must bear the statement: "The viscosity of this product will vary inversely with temperature."

4.3 Vitamin A and Beta Carotene Guarantees

Vitamin A guarantees on feed labels account for the total vitamin A activity of the feed, and include the activity from both vitamin A and beta-carotene (a vitamin A precursor). Beta-carotene is a single ingredient feed and is listed in Part II of Schedule IV of the Feeds Regulations. Therefore, only registered sources of this vitamin can be used in livestock feeds.

As requirements for beta-carotene have been well established in most livestock species, the Feed Program will allow guarantees on feed labels for minimum mg/kg of beta-carotene in addition to vitamin A guarantees.

Feeds with label guarantees for beta-carotene require registration as Category 2 (see Chapter 1) products, with the appropriate application fees. The registration will include additional requirements for the name and source of beta-carotene and the product formula. The feed label will have to indicate that the vitamin A guarantee includes vitamin A activity from beta-carotene.

For example:
Vitamin AFootnote 1 - minimum - 200,000 IU/kg
Beta-carotene - minimum - 100 mg/kg

In such cases, the following conversion factors (depending on species) will be used to determine the vitamin A activity from beta-carotene in the feed:

Feeds for:Vitamin A activity from 1 milligram of beta-carotene
Poultry 1,667 IU
Swine 149 IU
Cattle 400 IU
Sheep 681 IU
Horses 400 IU

Standard mixed feeds containing registered sources of beta-carotene may be exempted from registration as long as there is no reference by name (other than in the list of ingredients, if present) and/or guarantee to this ingredient on the label, and all other criteria for exemption from registration under the Feeds Regulations are met.

4.4 Vitamin Guarantees for Ruminant and Horse Feeds

Dietary requirements of three fat soluble vitamins (vitamins A, D, and E) for ruminants and horses have been well established. Dietary sources of other vitamins, such as vitamin C, vitamin K, and the B vitamins, including niacin and choline, have not been proven to provide any specific benefits to these species. As such, the CFIA's Feed Program has established the following guidelines for vitamin guarantees for ruminant and horse feeds.

  1. Guarantees for levels of vitamins A, D, and E shall be stated on the label of ruminant and horse feeds as outlined in the Feeds Regulations.
  2. Feed manufacturers may guarantee levels of vitamins other than vitamins A, D, and E in feeds for calves (up to three months of age), kids, and lambs (up to two months of age). This is essentially the pre-ruminant stage of the animal, when the rumen has not become fully functional.
  3. Feeds for horses may guarantee levels of riboflavin, pyridoxine, and thiamine, in addition to the vitamin A, D, and E guarantees.
  4. Vitamin guarantees other than those indicated in items 1, 2, and 3 above will only be allowed on feeds for horses, cattle, goats or sheep provided the following "Note(s)", where appropriate, appear(s) on the feed label:
    1. Cattle Feeds:
      "Feeding vitamins other than vitamins A, D, and E to cattle older than three months of age may not have a beneficial effect".
    2. Sheep Feeds:
      "Feeding vitamins other than vitamins A, D, and E to sheep older than two months of age may not have a beneficial effect".
    3. Goat Feeds:
      "Feeding vitamins other than vitamins A, D, and E to goats older than two months of age may not have a beneficial effect".
    4. Horse Feeds:
      "Feeding vitamins other than vitamins A, D, E, riboflavin, pyridoxine, and thiamine to horses may not have a beneficial effect".

Please note that feeds for ruminants and horses with vitamin guarantees other than vitamins A, D, and E require registration, and the addition of any new guarantees to a product label will be considered significant changes and will require an amendment to registration.

This section will be amended as dietary requirements are established for vitamins other than those stated above. Changes to registered ruminant product labels as a result of the current amendment will be required on registration renewal. Companies are reminded that they may submit any information pertaining to this issue to the Feed Program for evaluation.

4.5 Vitamin D3 and 25 - Hydroxyvitamin D3 Guarantees

Crystalline 25-Hydroxyvitamin D3 is a single ingredient feed that is approved as a source of vitamin D3 activity in complete feeds and supplements for drinking water for chickens and turkeys and complete feeds for swine in Canada. Crystalline 25-Hydroxyvitamin D3 is listed in Part II of Schedule IV of the Feeds Regulations, which means that only registered sources of this vitamin can be used in feeds in Canada. As there is no standard analytical method to determine the vitamin D3 activity from 25-hydroxyvitamin D3 in mixed feeds, the following policy will apply.

Vitamin D3 guarantees on labels for complete feeds and supplements for drinking water for chickens and turkeys and complete feeds for swine will be considered as the sum total of the Vitamin D3 activity from D-activated animal sterol, Vitamin D3, and crystalline 25-hydroxyvitamin D3. The amount of Vitamin D3 activity supplied by crystalline 25-hydroxyvitamin D3 will depend upon the label guarantee of each registered source. Presently, the only approved source of crystalline 25-hydroxyvitamin D3 supplies the following activity: 1 mg of 25-hydroxyvitamin D3 = 40,000 IU of Vitamin D3 activity.

Mixed feeds containing crystalline 25-hydroxyvitamin D3 may be exempt from registration, as long as there is no reference to this ingredient (other than the ingredient name and registration number, when a list of ingredients is present on the label) either by name, guarantee or claim on the label, and all other criteria for exemption from registration under the Feeds Regulations are met.

If the presence of crystalline 25-hydroxyvitamin D3 is highlighted on the label for a mixed feed, the mixed feed must be registered, and the following additional information (compared to a standard product registration) will be required as part of the application for registration:

  1. a label with a guarantee for the minimum concentration of 25-hydroxyvitamin D3, in mg/kg;
  2. the vitamin D3 guarantee on the label will have to specify that it includes all sources of vitamin D3 activity;
  3. the complete and detailed product formula (i.e., indicating the inclusion rate of each ingredient in the formulation, either on a weight/weight or percent basis), which will be used to verify both the label guarantee and the use of a registered crystalline 25-hydroxyvitamin D3 source;
  4. either the brand name or the approved single ingredient feed name (i.e., crystalline 25-hydroxyvitamin D3) in addition to the registration number of the source of crystalline 25-hydroxyvitamin D3 are to be indicated on the labels for standard mixed feeds and supplements; and
  5. the appropriate fees for a category 2 type application, as per Chapter 1 of the Regulatory Guidance.

For registered feeds, any proposed changes to the registration (e.g., product formulation, label guarantee(s), directions for use, intended species, the source of crystalline 25-hydroxyvitamin D3 used in the feed, etc.) must be first approved by the Animal Feed Division, via an application for a significant change to the registration that is accompanied by registration fees for a Category 2 type submission. Also please note that at registration renewal, the product formula must be submitted in support of the previously approved source and inclusion rate of crystalline 25-hydroxyvitamin D3.

Note: Additional information may be requested by the Animal Feed Division.

4.6 Selenium Supplementation of Livestock Feeds

Livestock Species Excluding Dry and Lactating Dairy Cows

The levels of supplemental selenium (Se) permitted in livestock feed, excluding lactating and dry dairy cattle are:

A) Complete Feeds

  • in complete feeds for swine, chickens, turkeys, ducks, geese, beef cattle, growing dairy cattle (non-lactating heifers, bulls and steers), sheep and goats, at a level not to exceed 0.3 mg/kg.
  • in the dry material of milk replacers for calves, lambs, colts and piglets, at a level not to exceed 0.3 mg/kg.
  • in complete feeds for rabbits and salmonid fish, at a level not to exceed 0.1 mg/kg.
  • in complete feeds for non-food producing livestock, at nutritional levels.

B) Limit fed feeds

  • at a level not to exceed an intake of 3 mg Se/head/day for beef cattle and 0.7 mg Se/head/day for sheep.

C) Free-choice trace mineralized salts and free-choice mineral feeds

  • in free-choice trace mineralized salts for all classes of beef cattle at a level not to exceed 120 mg/kg;
  • in free-choice trace mineralized salts for all classes of sheep at a level not to exceed 90 mg/kg;
  • in a free-choice mineral feed for all classes of beef cattle on range at a level not to exceed 30 mg/kg.

Dry and Lactating Dairy Cows

Per Table 4 of the Feeds Regulations, a complete feed for dairy cows refers to the grain ration. The Sixth Revised Edition (1989) of the Nutrient Requirements of Dairy Cattle suggests a selenium requirement of 0.3 mg/kg of total ration dry matter for dry and lactating dairy cows. The amount of grain ration fed to dairy cows is dependent on a number of factors including; forage quality, body size and condition, milk production, stage of lactation and age. To allow dry and lactating dairy cows access to an appropriate level of supplemental selenium, values have been established with input from industry which would incorporate some of these factors and permit an increased level of selenium supplementation.

The levels of supplemental selenium permitted in feeds for lactating and dry dairy cattle are found in Table 2. These values were calculated based on expected dry matter intakes for dairy cows weighing between 400 and 700 kg using Table 6-1 of Sixth Revised Edition (1989) of the Nutrient Requirements of Dairy Cattle. Values used in the calculation of maximum daily selenium intakes are found in Table 1.

Table 1: Values used to calculate maximum allowable daily selenium intakes

Body Weight (BW) 400 kg 500 kg 600 kg 700 kg
Milk Production 20 kg 25 kg 30 kg 30 kg
Dry Matter Intake % BW 3.6% 3.5% 3.5% 3.2%
Daily Dry Matter Intake 14.4 kg 17.5 kg 21.0 kg 22.4 kg
Maximum Daily Se Intake Dry Matter 4.32 mg 5.25 mg 6.30 mg 6.72 mg

Table 2: Maximum allowable daily selenium intakes

Body Weight 400 kg 500 kg 600 kg 700 kg
Maximum Daily Se Intake (as fed, 95% Dry Matter) 4.1 mg 4.99 mg 5.99 mg 6.38 mg

The feed manufacturer will be responsible for the development of a table of maximum allowable daily intakes for each product for body weights from 400 to 700 kg. This table will be required to appear on the label of each product. It will be calculated using the Maximum Daily Selenium Intakes (95% dry matter, as fed basis) shown in Table 2.

Values for developing the table for the label are obtained using the following equation where all values are expressed on an as fed basis:

Maximum Daily Intake of Product (kg/day) = Maximum Daily Selenium Intake (mg/day) ÷ Product Selenium Level (mg/kg)

For example:

  1. a dairy grain ration containing 0.6 mg/kg added selenium (as fed) would have on its label the following table (not including calculations shown in bold):
    Body Weight (BW) 400 kg 500 kg 600 kg 700 kg
    Maximum Daily Intake of Product (as fed) 4.10 ÷ 0.6 = 6.8 kg 4.99 ÷ 0.6 = 8.3 kg 5.99 ÷ 0.6 = 10.0 kg 6.38 ÷ 0.6 = 10.6 kg
  2. a protein supplement containing 3.0 mg/kg added selenium (as fed) would have on its label one or both of the following tables depending on feeding directions:

    a. Top Dressing

    Body Weight (BW) 400 kg 500 kg 600 kg 700 kg
    Maximum Daily Intake of Product 1.4 kg 1.7 kg 2 kg 2.1 kg

    b. Mixed at 150 kg/tonne finished feed (Ration = 0.45 mg/kg Se)

    Body Weight (BW) 400 kg 500 kg 600 kg 700 kg
    Maximum Daily Intake of Dairy Ration 9.1 kg 11.1 kg 13.3 kg 14.2 kg
  3. a mineral supplement containing 25.0 mg/kg added selenium (as fed) would have on its label one or both of the following tables depending on feeding directions:

    a. Top Dressing

    Body Weight (BW) 400 kg 500 kg 600 kg 700 kg
    Maximum Daily Intake of Product 164 g 200 g 240 g 256 g

    b. Mixed at 30 kg/tonne finished feed (Ration = 0.75 mg/kg Se)

    Body Weight (BW) 400 kg 500 kg 600 kg 700 kg
    Maximum Daily Intake of Dairy Ration 5.5 kg 6.7 kg 8 kg 8.5 kg

    Labels for all feeds containing selenium for dry and/or lactating dairy cows, regardless of product selenium level, must contain the aforementioned table indicating maximum product intakes. Any labels which do not contain the aforementioned table will be considered in violation of the Feeds Act and Regulations and will be subject to enforcement action.

    Any products containing the higher selenium levels will, of course, be required to bear labels reflecting the higher supplemental levels and the required table prior to being marketed.

    Note 1: Beef cattle, sheep, goats and dairy cattle may receive only one source of supplemental Se.

    Note 2: The minimal level of supplemental Se may be as low as 30% of the maximum permitted.

Labelling Requirements For All Species Including Dry and Lactating Dairy Cows

The following information is required on the labels of feed containing supplemental Se in addition to the specific requirements for feeds designed for feeding to dry and lactating dairy cows:

  1. Immediately above the guaranteed analysis
    "This feed contains added selenium at space mg/kg".
  2. Caution to appear on all feed labels:
    "Directions for use must be carefully followed".
  3. Caution to appear on cattle, goat and sheep feed labels:
    "Do not use in association with another feed containing supplemental selenium".

Additional Label Information

Permission has been granted under Section 30 (b) of the Feeds Regulations to allow a "total" actual selenium guarantee, expressed in mg/kg to appear on feed labels.

In order to proceed with a "total" guarantee, manufacturers must notify the Animal Feed Division and receive approval for the guarantee. In addition, the company must provide the feed formulation to justify the level guaranteed, as well as submit information on manufacturing quality control to demonstrate that the total guaranteed will be maintained consistently.

Based on statistical analysis of analytical results, a permitted analytical tolerance of plus/minus (40% of the selenium guarantee + 0.02 mg/kg) will be utilized to determine compliance of any product to its guaranteed level of "total" actual selenium.

The level of "added" selenium is still required to be stated on the feed label.

Mixing Ability

No difficulties have been encountered by feed manufacturers in mixing supplemental Se when producing feeds using macro-premixes or supplements containing Se. Firms using either a macro-premix or supplement from a firm previously cleared for mixing supplemental Se will not have to show proof of mixing ability.

If, however, a feed mill is manufacturing any of the following types of feed, a clearance demonstrating Se mixing ability is required:

  1. Selenium premixes (Se and carrier).
  2. Micro-premixes containing Selenium.
  3. A feed where one of the above types of premixes has been used.

    In order to obtain a clearance, we would ask that you submit one sample from each third of a batch (total 3 samples) of feed to a reputable laboratory for a Se assay. The results of that assay should be maintained at the feed mill and be made available to CFIA upon request.

Veterinary Prescriptions

Pursuant to Section 5 (2)(g)(v) of the Feeds Regulations, all veterinary prescriptions which prescribe supplemental selenium levels in excess of 0.3 mg/kg, in the total diet, for any class of livestock, must be submitted by the manufacturer of the feed, within 10 working days of the time of initial manufacture of the veterinary prescription feed.

4.7 Selenium Supplementation of Feeds for Lactating or Dry Cows

As a result of the modifications in section 4.6, free-choice feeds, including feed blocks for lactating or dry dairy cows, may no longer contain supplemental selenium.

Members of the feed industry have requested that feed blocks designed for feeding to lactating and/or dry dairy cows be permitted to continue to contain supplemental selenium. After consultation with the Veterinary Drugs Directorate regarding this request, it was decided that inclusion of supplemental selenium in feed blocks for lactating or dry dairy cows may be appropriate where appropriate voluntary consumption data for the feed block is submitted for evaluation.

Voluntary consumption data will be required for each specific formulation for which selenium supplementation is requested. This voluntary consumption data must be collected on a biweekly basis, for a minimum of 90 days, under the suggested feeding regime (e.g. pasture) for both lactating and dry dairy cows. Selenium assay data for the blocks used and an estimate of the coefficient of variation (% CV) must be supplied for each study. A minimum of three (3) studies are required.

4.8 Salt Guarantees

An actual guarantee for salt is permitted on labels of complete feeds, supplements and macro-premixes, in addition to a guarantee for actual sodium. This is in accordance with the Feeds Regulations, Section 30 (i.e. it conveys useful information to the feed purchaser). Such feeds will continue to be exempt from registration if they meet the other exemption requirements listed in regulation 5(2)(d) of the Feeds Regulations (i.e., the nutrient levels guaranteed are within the limits stated in Table 4 of Schedule I).

4.9 Amino Acid Guarantees on Livestock Feed Labels

The importance of the amino acid content of livestock feeds, especially for monogastric animals, is well documented, and acceptable laboratory methodologies for the verification of amino acid guarantees in feeds are available. The Science Branch of the CFIA has developed analytical tolerances for specific amino acids, which allow for the addition of amino acid guarantees on livestock feed labels.

At this time, only two amino acids have been considered, namely lysine and methionine. Both of these amino acids can be analyzed using the Association of Official Analytical Chemists (AOAC) International Official Methods of Analysis suitable for total amino acid analysis: AOAC International 994.12, "Amino Acids in Feeds", Performic Acid Oxidation with Acid Hydrolysis - Sodium Metabisulfite Method, or AOAC International 985.28, "Sulfur Amino Acids in Food and Feed Ingredients", Ion Exchange Chromatographic Method, or AOAC International 982.30, "Protein Efficiency Ratio", Part E - Sample Hydrolysis. For additional details of lysine and methionine testing, refer to the collaborative study for AOAC International 994.12 in the Journal of AOAC International Volume 77, Number 6, 1994, pages 1362 to 1402, by C. Llames & J. Fontaine, "Determination of Amino Acids in Feeds: Collaborative Study". The AOAC International methods mentioned above will be used by the CFIA for regulatory and compliance purposes.

2-Hydroxy-4-(methylthio) butanoic acid (HMB), which is commercially known as Methionine Hydroxy Analog, may be used as an alternative source of methionine activity in livestock rations; however, analytical methods for methionine determination cannot quantify HMB. For analytical determination of HMB content of livestock feeds, the methodology described by Ontiveros et al. (Journal of Agricultural and Food Chemistry (1987) 35 pages 692-694) has been reviewed by Science Branch and found acceptable.

The Feed Program of the CFIA allows for lysine and/or methionine guarantees (including methionine equivalent from HMB) only on labels of feeds designed for feeding to swine and poultry. These guarantees will be permitted on labels for swine and poultry feeds where all of the following conditions are met:

  1. As amino acid guarantees are not required pursuant to Schedule I, Table 3 of the Feeds Regulations, all products labelled with lysine and/or methionine guarantees are required to be registered. Please note, there is no exemption from this requirement with respect to customer and/or consultant formula feeds, or any other feed presently exempt from registration.
  2. Lysine and/or methionine guarantees will be permitted only on labels of feeds designed for feeding to swine and poultry. Amino acid guarantees for feeds designed for multiple livestock species will be permitted only if mixing directions are presented for swine and/or poultry and the amino acid content of the mixed feed is acceptable for those species.
  3. Only guarantees for minimum per cent of total lysine and/or methionine activity (including methionine equivalent from HMB) will be permitted. Guarantees for added lysine and/or methionine activity are not acceptable. Manufacturers will be required to submit a certificate of analysis stating the actual amount of lysine and/or methionine (including HMB where applicable) found for three different batches of the product, or copies of the actual product formula complete with calculated amino acid and HMB (where applicable) content.
  4. Where the feed is a complete feed, the amino acid guarantee must provide at least the minimum requirement recommended in the latest version of the Nutrient Requirements for Swine or Poultry published by the National Academy Press (for the age or class of animal for which the feed is designed), or be substantiated by other scientific information. Where the feed is designed for further mixing (i.e., supplements, macropremixes or micropremixes), the amino acid guarantee must result in a final feed which provides at least the minimum requirement, when the feed is manufactured as indicated on the label.
  5. Where the feed contains HMB as a source of supplemental methionine activity, the presence of HMB must be indicated on the label, beside the methionine guarantee (e.g. "this feed contains HMB as a source of supplemental methionine"), to ensure that the lab and/or analyst has the appropriate information to enable verification of label guarantees. A guarantee for minimum %HMB may also appear on the label, but will not be required.
  6. The analytical tolerance used for guarantee verification shall not exceed a deficiency of 20 per cent of the guaranteed amount.
  7. For amino acids manufactured using fermentation and extraction processes, the source of fermentation (bacteria, yeast or fungi) must be an approved source as per Schedule IV of the Feeds Regulations. Unapproved fermentation sources will have to undergo an ingredient safety evaluation prior to being used as an amino acid source. For fermentation sources containing a novel trait (e.g. genetically modified), the sources will be individually evaluated on a case-by-case basis, according to the Guidelines for the Safety Assessment of Novel Feeds: Microbial Sources.

For consideration of any additional amino acid guarantees (for other species or other amino acids) on livestock feed labels, valid scientific evidence in support of the nutritional requirement for the amino acid and a valid analytical method must be presented.

4.10 Fibre Guarantees for Livestock Feeds

Revised: 2010-10-19

For a number of years, livestock nutritionists have been using Acid Detergent Fibre (ADF) and/or Neutral Detergent Fibre (NDF) as indicators of dietary energy and intake, particularly in ruminant rations. As a result, these fibre fractions have replaced crude fibre (CF) in ration formulations. AOAC International has published methods for ADF and NDF determination in livestock feeds (Method #973.18 and Method #2002.04, respectively) and these methods are publicly available.

Given the above, the Animal Feed Division will allow guarantees for maximum per cent ADF and/or maximum percent NDF on feed labels, as per the following options:

Ruminant livestock feeds:

  • CF guarantee, or
  • ADF and/or NDF guarantees in addition to CF guarantee.

Non-ruminant livestock feeds:

  • CF guarantee only.

Single ingredient feeds:

  • CF guarantee, or
  • ADF and NDF guarantees in addition to a CF guarantee.

Multi-species feeds (ruminant and non-ruminant livestock):

  • CF guarantee, or
  • ADF and/or NDF guarantees in addition to a CF guarantee.

The presence of ADF and NDF guarantees on feed labels (as per product type above) that meet all other criteria for exemption from registration under the Feeds Regulations will not require registration by the Animal Feed Division.

4.11 International/Multilingual Labels

revised: 2015-02-03

Scope

The products to which this guidance applies are limited to single ingredient feeds or pre-mixtures used to provide select nutrients in the manufacture of livestock feeds.

Requests for multi-country/multilingual labelling have been periodically received by the Animal Feed Division. These are requests to include the labelling requirements and languages for foreign countries, in addition to those of Canada, on the same label.

Under the Feeds Act and Regulations, the definition of a label encompasses all the information (including symbols, marks or designs) that is applied or attached to, belonging to or accompanying any feed or package. This includes any details that may be intended for other countries.

Additional Label Information and Requirement for Registration

Labels for livestock feeds must contain the labelling information required by the Feeds Regulations. Any extra label information could be contrary to the standards outlined in the Feeds Regulations. Therefore, any company wishing to manufacture, import or sell a feed labelled with additional information must submit an "Application for Feed Registration" for the product in question, to the Animal Feed Division for review and assessment.

Additional Languages

The Feeds Regulations specify that "any information required to be shown on a label shall be printed conspicuously, legibly and indelibly in English or French or both languages."

The Animal Feed Division will consider additional labelling information that is beyond what is required by the Feeds Regulations, such as languages other than French or English on livestock feed labels, provided that an Application for Feed Registration or Renewal (CFIA/ACIA 0009) is submitted to our office in order to have a multi-lingual label approved for a given feed.

All products with additional label information or with languages other than French and/or English on the label must be registered, even if they would otherwise be exempt from registration. This includes single ingredient feeds listed in part I of Schedules IV and V of the Feeds Regulations.

A complete translation of the label information (other than French or English) must be included with the application for registration in order to determine if there are any statements and/or claims that contravene the Feeds Act and Regulations (e.g. therapeutic uses or claims, rates of use in excess of maximum safety limits for the ingredient, feeds for species that are not regulated under the Canadian Feeds Act and Regulations).

Such supporting information must be accompanied by a Certificate of Translation, or attestation that the translations are accurate (see Appendix I as an example).

Registration and Labelling requirements

The information required in order to comply with the Feeds Regulations must appear on the main panel of the package and must be presented in a manner that is not confusing, nor provide conflicting information to the user. Additional or alternative guarantees may be allowed on a case-by-case basis so long as they provide useful information to the purchaser and do not conflict with any requirements of the Feeds Regulations.

The requirement for a Certificate of Translation or attestation regarding the accuracy of the translation for multilingual labels is in addition to the registration requirements outlined in Chapter 1 of the RG-1 for the various feed types; there is no additional fee over and above that which is outlined in the RG-1.

If inspectors find unregistered products with additional label information, or in languages other than French and/or English on the label during their inspection activities the product will be considered non-compliant, and require corrective action.

If a company is uncertain whether their product requires registration, they should contact their local CFIA office or e-mail the Animal Feed Division at: afd_daa@inspection.gc.ca for guidance.
