Effects Of Feeding Distillers Grains Throughout Different Phases Of Production On Shelf Life Of Ground Beef, Brandy D. Cleveland

Department of Animal Science: Dissertations, Theses, and Student Research

These studies analyzed the effects of feeding distillers grains on the shelf life of cooked and raw ground beef, and how the addition of postmortem or dietary antioxidants impact shelf life.

For study one, cattle were assigned to backgrounding diets containing low or high concentrations of wet distillers grains (WDGS) and either corn gluten feed or modified wet distillers grains (MDGS) during finishing. For study two, cattle were fed one of five finishing diets; corn, wet distillers grains (WDGS), WDGS + vitamin E, WDGS + Ethoxyquin/TBHQ, or WDGS + vitamin E + Ethoxyquin/TBHQ.

Shoulder clods from each dietary treatment were …

Impact Of Wet Distillers Grains Plus Solubles And Antioxidants On A Basic Mechanism Of Beef Tenderization, Michael D. Chao

Department of Animal Science: Dissertations, Theses, and Student Research

Feeding high levels of wet distillers grains plus solubles (WDGS) increases polyunsaturated fatty acid (PUFA) levels in beef. Perhaps, WDGS in feedlot diets increases PUFA concentration in the SR membrane, thereby altering membrane integrity, resulting in more rapid calcium leakage and improved tenderness. Feeding antioxidants may mitigate such effects. In the first study, effects of feeding 50 % WDGS on SR membrane composition, free calcium concentration and tenderness were studied. The SR membrane from steers fed WDGS were more tender, had higher free calcium concentration, had more PUFA, more phosphatidylcholine (PC), less phosphatidylethanolamine (PE) and less total phospholipids when compared …

Effects Of Cultivar And Distillers Grains Supplementation On Grazing And Subsequent Finishing Performance Of Stocker Steers Grazing Tall Fescue Pasture, L. W. Lomas, J. L. Moyer

Kansas Agricultural Experiment Station Research Reports

Four hundred thirty-two yearling steers grazing tall fescue pastures were used to evaluate the effects of fescue cultivar and dried distillers grains (DDG) supplementation during the grazing phase on available forage, grazing gains, subsequent finishing gains, and carcass characteristics. Fescue cultivars evaluated were high-endophyte ‘Kentucky 31’ and low-endophyte ‘Kentucky 31,’ ‘HM4,’ and ‘MaxQ.’ Steers were either fed no supplement or were supplemented with DDG at 1.0% body weight per head daily in 2009 or 0.75% of body weight per head daily in 2010, 2011, 2012, 2013, and 2014 while grazing. Steers that grazed pastures of low-endophyte ‘Kentucky 31,’ ‘HM4,’ or …

Effects Of Supplementation With Corn Or Dried Distillers Grains On Gains Of Heifer Calves Grazing Smooth Bromegrass Pastures, L. W. Lomas, J. L. Moyer

Kansas Agricultural Experiment Station Research Reports

Thirty heifer calves grazing smooth bromegrass pastures were used to compare supplementation with 0.5% of body weight per head daily of corn or dried distillers grains (DDG). Daily gains of heifers supplemented with corn or DDG were similar (P>0.05).
