Cow Herd DNA Roundup FAQs

Frequently Asked Questions Background The Cow Herd DNA Roundup (CHR) is a recent program launched by the American Simmental Association in collaboration with GeneSeek®. The CHR offers a 60% off 50K genomic panel including parentage ($20 compared to $50 equivalent test) to participating breeders who test their entire cow herd. If breeders also submit cow…

Red Charlie: A Newly Discovered Red Coat Color Variant

In the spring of 2015, the American Simmental Association had a report of a red calf confirmed to a tested homozygous black bull. While learning about this case, several sons of Remington Lock N Load, 2503661, appeared to carry a red coat color variant not recognized by the existing coat color test. These bulls all tested homozygous black but sired red calves. The American…

How does parent verification work?

Whether you use parent verification to confirm your breeding records, distinguish between AI and pasture bred calves, or to sort through progeny from a multi-sire pasture, parental validation is an important test for breeders. Roughly 10% of pedigrees reported across all breed associations are inaccurate. These are frequently honest mistakes but never-the-less, vital to fix to make informed breeding decisions.

Coat Color Dilution in Simmental Cattle

Simmental, Hereford, and Gelbvieh cattle can carry a mutation in a gene (called Pmel17) which causes a black coat color to be diluted to a grey color. This is a different mutation for coat color dilution from Charolais cattle. The dilution mutation is masked in red cattle (or at least not as obvious as the…

Would you like to have the equivalent of a lifetime of production records when making culling decisions on your replacement females? With GGP-LD you can!

On average, adding DNA testing (e.g. GeneSeek’s Low Density test [GGP-LD]) is like having 8 phenotypic measurements on progeny for an animal. That would take most cows a lifetime to produce. By adding GGP-LD testing, you can make your replacement heifer decisions as if you have information on her lifetime calf crop before she has…

What is the Wild Type coat color allele?

Most of us have a good understanding of the two most common coat color alleles ~ the red and the black versions. Black is dominant to red so red cattle must have two red alleles and black cattle can either have two black alleles (homozygous) or can carry a red allele (heterozygous). Wild Type is…
