CLARIFIDE for Dairy.  Pfizer, the name you can trust in animal health can now help you predict the future.

Identifying heifers with different levels of genetic potential helps you to make sound management decisions early on in a heifer’s life. This leads to more accurate genetic selection within a herd, increased genetic progress and future profitability. That’s why Pfizer Animal Health introduces the CLARIFIDE™ program for dairy combining the technology of the 6,000 DNA-marker panel and the consulting services of Canadian CLARIFIDE Accredited Veterinarians across the country.

Genomics in Dairy Cattle

Genomic technology is revolutionizing the way decisions are made on the dairy farm for both purebred and commercial operations. Even for the large commercial dairy, genomic results can be applied to make more profitable management decisions earlier on in those animals’ lives.

What is CLARIFIDE?

In Canada, CLARIFIDE is a Pfizer-branded program designed to deliver genomics consulting services to the dairy industry through field veterinarians who have made a commitment to on-going training in the field of genomics.

CLARIFIDE utilizes DNA-marker technology for optimizing selection and management of dairy replacement females in the Holstein, Jersey and Brown Swiss breeds. Genotypes are analyzed by the Canadian Dairy Network (CDN) and genomic evaluations are returned to the Dairy Producer and the CLARIFIDE Accredited Veterinarian in a CLARIFIDE report.

The CLARIFIDE Process

  1. The dairy producer orders the number of sample collectors needed through Pfizer Animal Health Canada or their CLARIFIDE Accredited Veterinarian.
  2. The dairy producer collects samples for DNA extraction (hair follicle samples or blood samples can be used for testing).
  3. The dairy producer completes the order form and submits it along with the samples to their CLARIFIDE Accredited Veterinarian.
  4. Samples are shipped to Pfizer Animal Health Canada for a QA process before being forwarded on to the Pfizer Animal Genetics lab in Kalamazoo, MI, U.S.
  5. DNA is extracted at the Pfizer lab and genotypes (DNA markers) are determined for each sample on the Low Density 6K panel.
  6. Genotypes are analyzed by the Canadian Dairy Network (CDN) and genomic evaluations are returned to the Dairy Producer and the CLARIFIDE Accredited Veterinarian in a CLARIFIDE report (Excel based).

Interpreting CLARIFIDE Results

Using a range of tools developed by Pfizer and Semex, CLARIFIDE Accredited Veterinarians will work with dairy producers to help them interpret the results so that they can make more informed decisions about sire selection, reproductive strategies and overall herd management.

About the Canadian Genetic Services Alliance

Effective May 1, 2012, Pfizer Animal Health has joined the existing alliance between the Canadian Dairy Network (CDN), the Holstein Association of Canada (Holstein Canada), and the Semex Alliance (Semex).  This new alliance fosters a collaborative approach to delivering predictive genetic information to the Canadian dairy industry, promotes female genotyping and assists Canada’s dairy producers in using genetic information to make sound management decisions and propagate desired traits.
