Ohio State Expert: June Good Time to Establish High Reproduction Standards for Heifers

Jun 20, 2012

 

PIKETON, Ohio – Livestock farmers, who are now in the midst of breeding season, may find that selling heifers that aren’t meeting breeding expectations may make better financial sense than keeping an animal that isn’t achieving satisfactory conception rates, an Ohio State University Extension expert said.  

Considering that heifers that become pregnant and ultimately produce calves offer livestock farmers more financial benefit to keep, producers may want to consider replacing those heifers that aren’t meeting their breeding demands, said John Grimes, beef coordinator for OSU Extension.  

“Given the current prices seen in today’s cattle markets, culling heifers with poor reproductive performance shouldn’t be a difficult decision,” he said. “In today’s cattle economy, the bottom line is, if we don’t get cows pregnant, we don’t get live calves.

“And having live calves to sell gives us the ability to pay the bills.”

While livestock farmers may be hesitant to make the decision to weed out underperforming yearling heifers, either by selling the animals as heavy feeder cattle or by feeding them a finishing ration for a short period and then selling them as market heifers, open heifers are selling at a premium price compared to historic levels, Grimes said.

Livestock producers with underperforming heifers are in a prime position to take advantage of this opportunity, he said.

Conception or fertility rates in heifers are very important, and producers need to establish tough standards in the beginning to avoid poor performance problems in the long term,” Grimes said. “A virgin heifer shouldn’t have problems becoming pregnant, but if producers find they are having conception or fertility problems in the beginning, those substandard performance problems will continue throughout the lifetime of the animal.

“Producers shouldn’t be afraid to have animals achieve the high standards that they want. Producers can sell the underperforming animals out of the herd and get some that will meet their standards.”

Livestock producers typically try to breed heifers to have their first calves at two years of age, he explained. But producers who are having trouble getting the heifer bred may want to consider cutting their losses and get them out of their herd, Grimes said.

“Producers who do will find that it will result in them having a higher-producing herd after a few years,” he said. “Culling the poor producers will help farmers develop a better herd, focusing on slow but steady improvement through selection pressure.”

Other considerations for livestock farmers include: 

  • A producer should expect excellent reproductive performance (90 percent conception rates) from a properly developed heifer.
  • Pregnancy status should be determined within 60 days after the conclusion of the breeding season through rectal examination, ultrasound or available blood tests. 
  • The cost of a pregnancy examination or test is a very small investment that can save an operation many dollars compared to the costs of maintaining an open female.
  • If she is adequate in size (60 to 65 percent of mature weight at puberty), has been involved in a sound health program, and has been exposed to a fertile bull or bred artificially with high-quality semen, there is little reason that she should not become pregnant in a 60- to 90-day breeding season.
