What is Clarifide®

Clarifide is an Australian genomic selection tool to assist in the detection of superior dairy heifers from as early as birth.

It was designed by DataGene and Zoetis in conjunction with: Dairy Australia, Dairy Futures CRC and the Department of Economic Development, Jobs, Transportation and Resources.

Clarifide allows informed selection and breeding decisions.

Clarifide What is it?

How does Clarifide® work?

Clarifide interprets the genetic information encoded in your heifers’ DNA and converts it into a practical decision making tool to help improve your selection and breeding decisions.

When used as part of your annual planning calendar, Clarifide allows you to predict the production, health and type potential of your heifers.

Clarifide helps avoid the expense of raising genetically inferior animals.

Clarifide and young heifers

Using Clarifide on young heifers will provide a breeding value with similar reliability to an ABV calculated for a 7thlactation recorded cow.

Clarifide - How does it work?

Clarifide reliably delivers a heifer’s ABV from birth

*Reference: 7th lactation reliabilities are averages published for recorded cows by ADHIS 2012; Clarifide reliabilities are the average reliabilities obtained in Australian commercial herds.

Clarifide confirms parentage

Clarifide - Percentage

Clarifide confirms sire records. This helps to avoid parent misidentification, which can assist in managing inbreeding and improve your farm records

Up to 15% of dairy animals are incorrectly identified due to mis-mothering at birth, mistaken identity of the sire or dam, lost animal identification or inaccurate records.

Clarifide allows you to manage heifers

Clarifide - Management

Clarifide delivers a return on investment


Only genotyping provides the most reliable information about your animal’s potential for early-life selection.


Act on the results from Clarifide to:

  • Cull an excess heifer inventory
  • Allocate higher value semen


Improved management of traits important to your production system

Increase the value of your herd

Avoid the cost of raising inferior heifers

Ensure future investments are only in your best animals

Clarifide FAQs

  • What breeds can test with Clarifide?

    What breeds can test with Clarifide?

    Clarifide can be used to evaluate Holstein or Jersey or crosses of these two breeds.

    Clarifide can be used on calves that are a mixture of Holstein and Jersey. If the sire is Holstein, the calf will go into the Holstein evaluation. If the sire is Jersey the calf will go into the Jersey evaluation.

    However it is important to remember that ABVs generated for Holsteins cannot be directly compared with ABVs generated for Jerseys.

  • Where does the data come from?

    Where does the date come from?

    This is an Australian prediction developed by scientists at the Victorian Department of Primary Industries in collaboration with the Australian dairy industry including DATAGENE, Holstein Australia and Dairy Australia.

    These predictions were developed with Australian Breeding Values (ABVs) and were built for application to Australian animals and production systems. Clarifide results come out of the same analysis as the figures in the Good Bulls Guide published by DATAGENE.

  • Can I test bulls with Clarifide?

    Can I test bulls with Clarifide?

    Yes, you can test your paddock bulls with Clarifide. In fact, testing your bulls with Clarifide will improve Clarifide results for any heifers that are the offspring of the paddock bull.

    We will not test semen straws from AI bulls with Clarifide.

    Due to additional database recording fees associated with males bulls are more expensive than females, (refer to Zoetis Clarifide fee schedule).

  • How reliable is Clarifide? How is it validated?

    How reliable is Clarifide? How is it validated?

    On average, the reliability of Clarifide results is equivalent to the information recorded on a cow over over seven lactations. In short, the information from Clarifide exceeds that which would normally be recorded over a cow’s lifetime.

    For bulls, the reliability of Clarifide is calculated by estimating the correlation between genomic ABV and the true ABV (that is, how accurately the genomic test predicts the true ABV). The reliability of each Clarifide test is then calculated individually by the DATAGENE evaluation system and takes into account the reliability of the parent ABVs as well as the reliability of the genomic ABVs.

  • How is DNA extracted from the hair sample?

    How is DNA extracted from the hair sample?

    Hair follicles are trimmed from the hair shaft into a little tube and digesting these with enzymes that break down cell structures to release DNA into solution.

    DNA is then amplified (repeatedly copied) using a series of reactions to produce enough copies to conduct the Clarified tests.

  • How do you know what DNA relates to what trait?

    How do you know what DNA relates to what trait?

    Clarifide assess tens of thousands of DNA “markers” to predict the genomic breeding values (ABVg). These DNA markers employed for Clarifide are well-defined and commonly-used.

    Each marker is given a relative “weighting” for its contribution to a particular trait, and all of these weightings are combined across the thousands of markers measured for each animal to give a prediction of performance. The weighting contribution of each marker (the “equation”) is calculated from a resource population of thousands of animals to build the most accurate equation possible.
