  • Product name reflecting purpose of the product and the intended species
  • Product claim statement
  • Guaranteed analysis (major active ingredient(s))
  • Complete list of ingredients by generic name as listed in Schedule IV or V of the Feeds Regulations including registration numbers for Part II ingredients or mixed feeds as required
  • Directions for use to permit safe and effective use of feed
  • Caution and/or warning statements (if applicable)
  • Name and address of registrant
  • Net amount (metric measure)

Product Composition

  • Formulation / percentage composition listing amount of each ingredient by generic name as listed in Schedule IV or V of the Feeds Regulations including registration numbers for Part II ingredients or mixed feeds
  • Formulation / Ingredients - verify level of ingredients does not exceed maximums per Schedules IV and V.

Scientific Studies

  • Scientific studies are required to support the intended purpose of these products
  • Studies carried out by qualified personnel
  • Suitable methods used in studies
  • Studies designed to facilitate statistical analysis
  • Data analysed by appropriate statistical methods
  • Studies conducted under conditions similar to those that may be expected to occur in Canada
  • Scientific investigations show that the products when used as directed, significantly reduced the pH of feeds for each species/class for which they are intended. Where the directions for use indicate a range of inclusion rates, the testing protocol must evaluate the lowest inclusion rate.
  • Studies show a significant difference (P<0.05) between the control and treated groups
  • Where results of these studies have not been published in a refereed journal, copies of the raw data and printouts of statistical analysis are required for our review.

Lab Methods

  • Original signed copies of Certificate of analysis for a minimum of three lots of these products supporting label guarantees for the primary acidifying ingredients.
  • Information on the methodologies used to analyse the acid levels e.g. a copy of the AOAC International or other official method is required. In the event that these methods have not been peer-reviewed, additional information is required to validate the laboratory method as outlined in section 6.2
  • Analytical methodology substantiating the guarantee(s) (e.g. novel guarantee or method) - provided for CFIA Laboratories


  • Provided (if necessary to validate lab methodology)
