Effect of distillers grain on beef quality

// 22 dec 2006

Dr. Allen Trenkle of Iowa State University has summarized four ISU studies where cattle were fed up to 40% distillers grains. There was some reduction in marbling at these high levels, but the net value of the carcasses in a typical grid market did not differ greatly.

Taste panel analysis of tenderness, juiciness and flavor was not changed. Interestingly, corn gluten feed did not change marbling scores when fed up to 90% of the ration. Perhaps the fat content of the distillers grains may be the reason of the change in marbling.

Another recent analysis indicated a decline in marbling with distillers grains feeding but not until the level reached approximately 50% of the ration dry matter. No effect on marbling was found when studies where wet distillers grains were fed.

GMP: Critical in feed-to-food chain

Hinner Köster: Feed safety parameters as part of food safety is nowadays the highest priority when we evaluate feed quality. Nutritional, technical and emotional quality of feed used to be the highest priority and remains important for common industry policy, however, it is now of lesser importance then feed safety. Even developing countries are no longer isolated but part of a global world and are therefore partially regulated by universally established control systems at all stages of production and in all sectors of their industry.Read more...
