April 23 (Bloomberg) -- The genetic blueprint of domestic cows has been decoded in a scientific feat that traces bovine evolution and may lead to more nutritious milk, meat and increased food supply, scientists reported.
A six-year effort by more than 300 researchers sequenced and analyzed the 22

With the addition of genetic markers, the comprehensive IGENITY® profile has become an even more powerful tool for beef producers. DNA markers have been added to the analyses for marbling, quality grade, yield grade, hot carcass weight, fat thickness and ribeye area — making them more valuable for the

For many cow/calf producers, spring means making ever-important breeding and mating decisions. By using the power of DNA, those decisions can be made with more confidence by learning inside information about both bulls’ and females’ genetic potential.

It is important to differentiate between composite developers (breeders) and composite users (commercial producers). Developing a composite requires a large population of females (25 or more sires per generation or approximately 500 to 750 cows). It takes a considerable amount of time to make the initial

The first national sire evaluation in beef was published in the early 1970s comparing 13 sires for a limited number of traits. As time has gone on, both the number of animals and the number of traits with EPD have increased.
More recently, a more defined focus for EPD has been encouraged.

Heterosis refers to the superiority of the crossbred animal relative to the average of its straight bred parents. Heterosis results from the increase in the heterozygosity of a crossbred animal’s genetic makeup. Heterozygosity refers to a state where an animal has two different forms of a gene. It is
