Sheep 50K

Lead the Way with Sheep 50K

The world's first genomic tool for sheep now enters its third generation. Zoetis Genetics, in collaboration with Ovita, is proud to commercially offer an expanded panel for Sheep50K. This DNA panel consists of nearly 50,000 markers and provides genomic predictions which are expressed as Molecular Breeding Values (MBVs). Sheep50K helps New Zealand Romney, Coopworth, Perendale and Composite breeders make significant improvments in their breeding selection programs for 22 economically important traits include Adult Ewe Live Weight, Facial Eczema, Number of Lambs Born, Dag Score and more. Sheep50K reports include Percentage Ranks and a Sheep50K Index to aid the ranking of animals for selection purposes.

  • WHAT IS IT?
    Sheep50K® is a genomic selection tool, similar to Sheep5K®. Sheep50K® utilises a denser DNA panel of 50,000 markers rather than 5,000 for Sheep5K®. It also delivers molecular breeding values for the same breeds and traits as Sheep5K®, but is applied in a different way.

    The 5,000 markers from Sheep5K® are represented within the 50,000 markers of Sheep50K®. This becomes important in understanding how the Zoetis Genomic Suite integrates its various products.

    WHY DO I NEED TO USE IT?
    Sheep50K® is used strategically to ensure the value of genomics in your flock is retained. Genomics relies on a ‘fresh' resource of dense genotypes that represent the current industry and more importantly, your flock. If your flock is not represented within this resource of genotypes, the efficacy of genomics is unknown. In a similar fashion, if the genotype of your flock is not continually maintained in this resource, the efficacy of genomics diminishes over time.

     

  • HOW DO I USE IT?
    To ensure that your flock’s genotype is adequately represented within the genomic resource, Sheep50K® is best used on all sires. Testing sires with Sheep50K® is the most cost-effective way to ensure that your flock is represented within the genomic resource and that genomics continues to be of value to your breeding program.

    WHAT TYPE OF SAMPLE DO I NEED TO TAKE?
    All genomic tests require a punch of ear tissue. Semen sample may also be used.

    WHAT DO RESULTS LOOK LIKE?
    The results from a Sheep50K® test are essentially the same as those from a Sheep5K® test.

    WHERE, WHEN AND HOW DO I ACCESS MY RESULT REPORTS?
    The reports from a Sheep50K® test are also attained from Zoetis and SIL, similar to Sheep5K® reports.

  • Traits delivered from Genomics with Sheep5K and Sheep50K

  • The Zoetis Genomic Suite, which includes Sheep50K® and Sheep5K®, offers a lot to the Sheep industry, but like all tools, it has limitations.

    Prepare for your initial engagement with Zoetis by answering these preliminary questions:

    1 Is the animal you want to test, on SIL?
    Tested animals do not have to be registered on SIL, but their Sires should be. Establish the SIL birth ID of the animals being tested (or their Sire) before engaging Zoetis.

    2 Proximity to the Genomic Pool
    It’s important that any animal being tested is ‘close’ to the resource used in the development of the Zoetis Genomic Suite. Contact Zoetis to help establish the proximity of the animals you want to test, to the Genomic Pool.

    3 Breed criteria
    The Zoetis Genomic Suite can be used in these New Zealand Sheep breeds:

    BREED DESCRIPTION
    Romney >= 75% Romney
    Coopworth >= 75% Coopworth
    Perendale >= 75% Perendale
    Composite >30% Romney + Coopworth + Perendale

    "Breed" can be established from SIL (assuming the animal is registered on the SIL database).
