Distillers Grains Diets May Lead to Beef That is More Tender

OMAHA (DTN) -- Cattle consuming a diet containing distillers grains may produce beef that is more tender, according to recent research by a University of Nebraska-Lincoln graduate student.

Michael Chao finished his dissertation in May examining the effect of wet distillers grains plus solubles (WDGS) and antioxidant on beef tenderization. Chao is now an assistant professor at the California State University, Chico.

The idea for the research came from a former graduate student who said that while doing her research looking at shelf life and discoloration, she found that cattle fed distillers grains produced meat that was more tender than beef from cattle fed only corn.

Chao told DTN he was intrigued from the standpoint of science.

"Usually when we formulate a diet, we don't consider that any specific type of food would have a big effect on tenderness," he said.

Chao's research involved three studies:

1. Cattle were fed 50% WDGS. The sarcoplasmic reticulum (SR) membrane, free calcium concentration and tenderness were measured.

2. Cattle were fed 30% WDGS and two antioxidants: vitamin E and Agrado Plus (a blend of antioxidants produced by Novus International). Muscle tissue, fatty acid profiles, color and lipid oxidation were measured.

3. Cattle were fed 30% WDGS and the same two antioxidants. But in this study, SR membrane composition, composition and proteolysis (the degradation of muscle) were measured.

Chao found that feeding distillers grains actually improved the proteolysis of the meat.

"What happens in aging is that after an animal is dead, the enzymes start breaking down the muscle tissue. When animals are fed distillers grains, they age faster," he explained.

While no concrete answer exists, Chao said he has a hypothesis as to why distillers grains cause the accelerated breakdown of tissue. Distillers grains are very high in polyunsaturated fatty acids (PUFA). So when cattle consume a lot of distillers grains, PUFA get into the calcium-storing organelle, the part of the muscle cell that stores calcium, and make it less stable.

"When the organelle is less stable, the calcium leaks out from it faster. And the enzymes that degrade the muscle protein depend on calcium," Chao said. "So, the more calcium, the faster the degradation.

"So that's our hypothesis, that feeding distillers grains causes accelerated release of calcium, which causes faster aging," he said.

Chao said that if the theory is correct, it could have beneficial implications for beef producers, as meat that is more tender could be sold at a premium.

"If we can manipulate how we feed animals and make our meat more tender, we can have a tenderness advantage and we will be more competitive in the global market," he said.

Although there is no tenderness factor included in U.S. Department of Agriculture beef grading, Chao said USDA does have a very new tenderness certification that is attracting more and more producers. Meat can be certified as "USDA Tender" and "USDA Very Tender," he said. This new certification is not widely popular yet.

Chao says his graduate adviser, Chris Calkins, will be continuing this line of work through potential grants from the Nebraska Beef Council and the National Cattlemen's Beef Association.

Distillers Grains a Good Choice for Energy in 2015-16

Higher corn futures are now continuing to raise corn-derived energy to higher cost levels. In the coming year, livestock producers may want to consider alternative feeds such as distillers grains, according to an article by Farm and Ranch Guide (http://bit.ly/…).

Alfredo DiCostanzo, from the University of Minnesota Beef Team, said that corn and soy co-products such as distillers grains may be good alternatives to corn grain as energy sources in rations.

With current prices, corn-derived energy for cattle growth or maintenance will be priced at $158 to $176/ton total digestible nutrients (TDN), DiCostanzo said. With western Iowa modified distillers grains priced between $50 to $55/ton and wet distillers grains priced at $35 to $40/ton, energy from those sources costs $125 and $119/ton respectively.

At present, western Iowa modified and wet distillers grains are priced at $50 to $55/ton or $35 to $40/ton, according to the article. Energy derived from either source costs $124 and $119/ton TDN, respectively.

Except for several weeks in July, the value of distillers grains relative to corn had remained above 100% since mid-December 2014, sometimes rising as high as 120% to 130%, according to DTN statistics. Such high values caused some producers to drop distillers grains from their rations, as there was little incentive to choose distillers over corn.

The value of distillers grains relative to corn finally dipped below 100% in mid-September and has hovered around 86% for the past month.

These lower values have attracted interest and caused producers to reconsider distillers grains or increase the inclusion rates in rations.
