This is the first in a series of monthly articles about maximizing profits in today's changing livestock economy. Future topics will include stocking rates for stockers on winter pastures and Tifton 85 Bermuda grass; cow/calf performance on ryegrass or clover pastures; and cow/calf performance on pastures having no added commercial nitrogen.  

 

"Rain or shine, wet or dry, do you want to make more money from your cows next year?" asks a Texas AgriLife Research forage scientist.  

"It's possible primarily as today's high-priced corn has changed the way feedlots are doing business," said Dr. Monte Rouquette, AgriLife Research forage scientist.  

Traditionally, most livestock producers in East Texas and the southeastern U.S. have stuck to cow/calf operations, Rouquette said. In the past, calves were weaned at 350 to 450 pounds and then moved directly to feedlots for finishing. Part of this traditional calf-management strategy has to do with the price of corn used in feedlot rations.  

"Years ago, when it appeared as if $2 bushel corn was going to be here forever, the feeders developed animal health programs to allow them to secure lightweight calves and place these calves directly into the feedlot at weaning," he said. "These lightweight calves would remain in the feedlot for more than 250 days!"  

But corn prices have increased "dramatically" in the last few years, in part due to ethanol production, and have rocketed to as high as $8 per bushel a few weeks ago. Prices came down in January, but were still in the $5 to $6 range.  The response of the feeders has been to seek heavier-weight cattle for entry into feedlots, he said. For the livestock producer, "heavier-weight" cattle can mean just weaning calves later for a couple of hundred extra pounds or placing weaned calves on pastures for three to six months to increase weight and maturity. These longer-maintained cattle are commonly referred to as stockers.  

These management strategies spell opportunity for livestock producers to make higher profits from their cattle herd by producing the heavier cattle the feedlots now prefer.  "There are two primary strategies for selling heavyweight cattle," Rouquette said. "You can wean heavier-weight calves and maintain or purchase light-weight calves and place them on a stocker-grazing program, or do a mixture of both."

 Rouquette noted that the Texas AgriLife Research and Extension Center at Overton, where he is based, has 30 years of data on the "pasture and animal interaction" to show what does and does not work under East Texas and southeastern U.S. climatic conditions.

 Since the inception of the Texas AgriLife Research and Extension Center in 1967, one of the fundamental emphases has been forage management and animal performance, said Dr. Charles Long, resident director of research at the center.  

"First, heavyweight calves at weaning are produced primarily from cows that calve during the fall to winter period -- and not during the late spring to early summer period," Rouquette said.  This is because fall and/or winter-calving cows have access to winter annual pasture -- small grain, ryegrass, clover -- to provide the highest nutritive value possible for average daily gain to be high for the calves. It's not unusual for fall calves to wean at more than 700 pounds by early June, he said.
