Every pound counts at the sale barn — and sometimes, the weight loss happens long before calves ever hit the scale.
For cattle producers, shrink isn’t just a biological response to stress; it’s an invisible drain on profit margins that can be managed with the right timing and techniques, according to K-State beef cattle experts.
K-State veterinarian Brad White explains “shrink” as the weight loss that occurs between gathering calves at home and their final weigh-in at the scale.
“In general, I expect calves to lose weight if they’re sitting in a new environment, new water source, just transported and everything else,” says veterinarian Bob Larson. “So even though it might be easiest for me to take calves on the day that’s most convenient for me, in order to address shrink, I think it’s better to move that transport to the sale as late as possible.”
There are also economic implications associated with shrink.
“You think about a 500-lb. steer; you know, every 1% difference in shrink is 5 lb.,” Larson says. “And so you add a couple more percentages of shrink, and the amount of money we are talking about is easily offset by hiring somebody to help me gather them.”
Proper cattle handling techniques play a critical role in minimizing weight loss during the marketing process, the experts emphasize.
“We feel stressed because we have things to do, and we start rushing and pushing the cattle harder. We start losing those low-stress handling principles in the process,” beef cattle nutritionist Phillip Lancaster says. “Now that they are stressed, they have an increase in urination, defecation, and they start losing fluids and losing weight quicker.”
For producers concerned about shrink, online auction platforms may offer a useful alternative.
“One tool that producers have is methods that limit the amount of time the calves spend in the marketing system, such as marketing online,” Larson says.
The specialists concluded that shrink represents an invisible cost that doesn’t appear on invoices but significantly impacts producer profitability, making proper management essential for maximizing returns.
