Description

Coat Colour genes determine red or black coat. Black is the dominant trait. With Homozygous Black animals, all the progeny will be black even when mated to recessive red animals. With Heterozygous Black animals, 1/2 of progeny will be black and 1/2 will be red when mated to recessive red animals.

The polled allele causes animals to have an absence of horns and polled animals also may have a narrower skull. Polled is a dominant trait.

“Double Muscling” - muscle hypertrophy, may have larger birth weights, increased dystocia and increased tenderness. Animals are extremely muscled, with abnormally large, wide and rounded rump and thighs with prominent creases between muscles.

What to do with the data?

Knowing the free, carrier or affected status of cattle in a herd helps reduce and/or eliminate risk of propagating the disorders in future generations. If cows are free, you can choose a bull based on his genetics and/or phenotype that best fits your breeding objectives, whether or not he is a carrier. If cows are carriers or from carrier lineages, mate them only to non-carrier bulls. Replacement heifers from these matings should be DNA tested and/or mated to a non-carrier bull.

Carcass, Tenderness & Genetic Data

A complete list of carcass, tenderness and completed DNA test results for all the sale animals will be available on sale day or feel free to reach out to either Codiak Acres or River Hill Farm to inquire about individual lots.
