Effect Of Distillers Grains Supplementation On Calves Grazing Irrigated Or Non-Irrigated Corn Residue, Mandi Jones, James C. Macdonald, Galen Erickson Erickson, Terry J. Klopfenstein, Andrea K. Watson
Nebraska Beef Cattle Reports
Steer calves grazing irrigated or non-irrigated corn residue received supplementation of dried or modified distillers grains plus solubles (DGS) at 0.3, 0.7, or 1.1% of BW . Steers were individually supplemented daily through Calan gates. Daily gain improved quadratically with increasing supplementation (1.55 lb/day to 2.12 lb/day) and for calves grazing non-irrigated (2.02 lb/day) compared to irrigated (1.77 lb/day) corn residue. Feeding dry instead of modified DGS did not significantly impact ADG. Supplementing DGS to calves grazing corn residue increased gain during the winter period.

Nutrient And Tenderness Differences Of Beef From Heifers Due To Mutation Of The Myostatin Genehypothesized, Michelle E. Semler, Chris R. Calkins, Galen E. Erickson Erickson
Nebraska Beef Cattle Reports
Strip loins and eye of rounds were obtained from heifers genotyped with variations of the myostatin gene; 19 homozygous dominant (Angus), 20 heterozygous dominant (Angus x Piedmontese), and 20 homozygous recessive (Piedmontese). Steaks were aged for 14 days, cooked fresh (never frozen), and nutrient steaks were frozen three days postmortem. Meat from homozygous recessive heifers was equal in tenderness to homozygous dominant and heterozygous dominant heifers. Fat content of meat from homozygous recessive heifers decreased while moisture and protein increased compared to homozygous dominant and heterozygous dominant. Calorie content decreased with increasing copies of the recessive gene. Thus, meat from …

Effect Of Feeding De-Oiled Wet Distillers Grains Plus Solubles On Beef Fatty Acid Profiles, Katherine I. Domenech, Kim A. Varnold, Michelle E. Semler Semler, Michael D. Chao, Tommi F. Jones, Galen E. Erickson, Chris R. Calkins
Nebraska Beef Cattle Reports
A total of 336 steers were fed one of seven finishing diets: a corn-based control, 35%, 50%, or 65% inclusion of wet distillers grains plus solubles (WDGS), either traditional (full-fat) or de-oiled. At harvest, 15 low USDA Choice carcasses within each dietary treatment (n = 105) were selected to evaluate the effect of diet on the fatty acid profile of strip loin steaks aged seven days. Feeding WDGS increased the amount of polyunsaturated fatty acids (PUFA) in comparison to a corn based diet. Feeding de-oiled WDGS resulted in less PUFA’s than the full-fat WDGS diets. It seems that the removal …

Nebraska Beef Cattle Reports
Cattle fed a de-oiled wet distiller’s grains plus solubles (WDGS) diet were compared to cattle fed corn or traditional (full-fat) WDGS diets to determine effects on discoloration, oxidation, and tenderness of beef aged for seven and 21 days. At seven days of aging, dietary treatment had no effect on discoloration. At 21 days of aging, beef from cattle fed de-oiled WDGS had less oxidation than the corn control and several of the full-fat WDGS treatments. Although tenderness increased with aging and retail display, dietary treatment had no effect on tenderness. These findings suggest that these dietary treatments, followed by a …

Nebraska Beef Cattle Reports
Distillers grains use while wintering on cornstalks during summer grazing and during the finishing period was evaluated to determine the effects of lifetime exposure to distillers grains on meat characteristics. Finishing diets with distillers grains increased discoloration in steaks following six days of retail display for steaks aged seven days, and after four days of retail display for steaks aged 21 days. Supplementation during summer grazing increased discoloration when cattle were not finished using distillers grains. There were no differences in oxidative rancidity among dietary treatments. Supplementing with distillers grains prior to finishing was not additive in impacting the color …

Effect Of Natural Antioxidant Concentration On Lipid Oxidation Of Ready-To-Eat Ground Beef Links From Cattle Fed Distillers Grains In Different Phases Of Production, Brandy D. Cleveland, Joe O. Buntyn, Amy L. Redfield Redfield, James C. Macdonald, Galen E. Erickson, Tommi F. Jones, Ty B. Schmidt, Gary A. Sullivan
Nebraska Beef Cattle Reports
Shelf life of cooked ground beef links with no, low, or high concentrations of a blend of natural plant extract antioxidant were compared to evaluate lipid oxidation over time. When no antioxidants were added, samples stored nine days or beyond were more oxidized than the samples with the addition of an antioxidant. No differences in lipid oxidation were observed between 0.13% and 0.20% antioxidant concentrations during similar days of refrigerated storage days. Therefore, the addition of natural antioxidants were effective at reducing oxidative rancidity, regardless the concentration of antioxidant.

Nebraska Beef Cattle Reports
Forage savings and supplement loss caused by feeding on the ground were estimated when spayed yearling heiferswere fed modified distillers grains with solubles (MDGS) while grazing Sandhills summer range. Across two years, heifers fed 0.6% BW MDGS had 1.39 lb greater ADG and consumed approximately 17% less forage than non-supplemented heifers. Calculated loss of MDGS when fed on the ground was 5.6%. Supplementing MDGS decreased forage consumption approximately 17% and increased summer gains.

Nebraska Beef Cattle Reports
This ongoing study investigates the impact of diet and bacteriophage activity on the structuring of rumen microbial community composition and diversity. Fistulated cattle were acclimated to a given diet for 21 days before samples were collected and subsequently enriched for viral particles with tangential flow filtration. Taxonomic identification, abundance, and functional attributes were assigned to both bacterial and viral communities. Principle coordinate analysis of the bacterial communities revealed significant clustering based on diet. While diet drives the structuring of rumen bacterial communities, bacteriophages may maintain high, constant bacterial diversity.

Effect Of Micro-Aid® Supplementation On Nitrogen Losses From Manure, Andrea K. Watson, Galen E. Erickson, Terry J. Klopfenstein Klopfenstein, Mike J. Rincker
Nebraska Beef Cattle Reports
A 2x2 factorial designed experiment was used to study the effects of Micro-Aid and time on OM and N losses from manure, in a simulated feedlot pen setting. Manure was collected from cattle on a common diet, except for the addition of 1 g Micro-Aid /steer daily. Losses of OM were greater at 60 d than 30 d, and greater for control than Micro-Aid. Nitrogen losses at d 30 were similar between treatments but control pans had greater N losses at d 60. Feeding Micro-Aid to cattle may inhibit N volatilization from manure, enhancing the fertilizer value of manure.

Nebraska Beef Cattle Reports
Seven research trials conducted over five years at the University of Nebraska–Lincoln were summarized to determine how animal performance changes through the finishing period on a live and carcass weight basis. Live weight, carcass weight, carcass ADG, and carcass feed efficiency all changed quadratically throughout the feeding period; live ADG and live feed efficiency declined linearly. During times of negative profit margins, optimal profitability for steers marketed on a live-basis occurred by selling early, whereas optimal profitability was achieved by feeding steers marketed on a carcass-basis longer.

Nebraska Beef Cattle Reports
Crossbred steers (n = 64) were grazed on warm- or cool-season grasses, without or with energy supplementation of wet distillers grains with solubles (WDGS), and were finished on a corn-based diet with or without 35% WDGS. Grass-type was the major contributor in determining the biochemical composition of L. dorsi steaks, with warm-season grasses causing increased concentrations of moisture and zinc and decreased concentrations of magnesium. Aging 28 days instead of 7 days increased pH and caused an increased concentration of carbohydrates, and non-heme and heme iron in B. femoris steaks. Diet, especially grass type, during grazing, can alter the end …

Nebraska Beef Cattle Reports
Crossbred steers (n = 64) were grazed on warm- or cool-season grasses, without or with energy supplementation of wet distillers grains with solubles (WDGS), and were finished on a corn-based diet with or without 35% WDGS. Grass type was the major contributor in determining the fatty acid profile, especially in the neutral lipid layer. Warm-season grasses decreased concentrations of most fatty acids compared to cool-season grasses. The provision of WDGS as an energy supplement while grazing dissipated any differences caused by grass type.

Nebraska Beef Cattle Reports
Yearlings rotationally grazing smooth bromegrass were individually supplemented modified distillers grains plus solubles (MDGS) at .05, 0.4, 0.6, and 0.8% BW. Gain increased quadratically as MDGS level increased. Maximal ADG (2.95 lb/d) was predicted when supplementing level of 0.48% of BW. Economic analysis compared 0, 2, and 5 lb (DM) MDGS supplementation. When cattle ownership was retained through the feeding period, MDGS supplementation was profitable. Supplementation at 2 lb (DM) was more profitable than 5 lb (DM) when MDGS is above $265.63/ton (DM) or 85% the price of $7.50 /bu corn.

Effects Of Grazing On Nebraska Sandhills Meadow Forage Nutrient Content, Jared V. Judy, Jacki A. Musgrave, L. Aaron Stalker Stalker, Karla H. Jenkins, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
Nebraska Sandhills subirrigated meadow pastures were utilized to measure the effects of grazing on forage nutrient content in summer pastures. Pre-grazed pastures had greater protein and in vitro dry matter digestibility levelsand lower neutral detergent fiber levels compared with post-grazed pastures early in the grazing season. By late July, post-grazed vs. pre-grazed pastures did not differ in in vitro dry matter digestibility and neutral detergent fiber levels. Observed results indicate the greatest differences in nutrient content between post-grazed and pre-grazed pastures occur early in the grazing season.
