Coordinating Sire Genetics
in a Synchronized AI program
JOPLIN, Mo. (Aug. 31, 2011) — Variability is a big challenge in the beef industry. Predictable quality and production levels are affected by individual ranch management and environment as well as cattle genetics.
University of Missouri (MU) economist Joe Parcell led a team that looked into the production and marketing potential of coordinating sire genetics, as well as age, source and health verification. He summarized and commented on the work Wednesday, Aug. 31, at the Applied Reproductive Strategies in Beef Cattle (ARSBC) meeting in Joplin.
The white paper in the proceedings focuses on a study of 328 Angus-based calves in four sire-class groups, compared through harvest. Therein, the group from high-accuracy sires demonstrated many advantages, including the highest Certified Angus Beef® (CAB®) brand acceptance of all at 67%.

In comments, Parcell was more expansive.
“We want to see how this technology can impact your bottom line,” he said. “When you synchronize heat and use high-accuracy sires in fixed-time artificial insemination (FTAI), you take out much of the variability.”
Other, prior research showed a 25% variation in mean feeding value of calves from highly proven sires, compared to 89% variation from low-accuracy sires, he noted.
Parcell said technology can be “bundled” to amplify advantages. Adding detail to cow herd production records can help chart known genetics over several generations, and those records can be enriched with feedlot and carcass data.
Increasing use of FTAI along with these records can “stack sire and cow genetics, and in effect that leads to highly accurate cows,” he said. Marketing of calves is best accomplished through some kind of alliance, but the sale barn can be part of that, Parcell added.
Many producers resist using AI because they believe it is too expensive, but the economist took aim at that idea. “If you have more than 50 cows and spend more than $3,000 for a bull,” he said, “you can benefit from using AI.”
Parcell spoke during Wednesday's ARSBC session focused on the genomic and economic considerations of producing high-quality cattle.
