OmniGen- AF (Phibro Animal Health, Quincy, IL) was fed to steers to evaluate the effects on the metabolic and immune response during an immune challenge, as well as feedlot performance. Th e inclusion of OmniGen- AF for either the first 28 d or the entire feeding period) did not impact feedlot performance or carcass characteristics. However, within a subset of cattle receiving an immune challenge (the endotoxin lipopolysaacharide; LPS), OmniGen- AF supplementation did alter the metabolic and immune profile of steers. These results suggest that feeding of OmniGen- AF may enhance the metabolic and immune response if cattle are challenged …

Evaluation Of The Relative Contribution Of Protein In Distillers Grains In Finishing Diets On Animal Performance, Zachary E. Carlson, Galen E. Erickson, James C. Macdonald Donald, Matt K. Luebbe
Nebraska Beef Cattle Reports
A finishing study evaluated the relative contributions of protein from wet distillers grains plus solubles (WDGS) on feedlot performance and carcass characteristics. The protein portion of WDGS was mimicked by corn gluten meal (CGM). Increasing WDGS inclusion from 0 to 40% increased final body weight and gain, decreased intakes, and improved feed efficiency. When CGM was fed to equal protein concentration as WDGS, final body weight and gain increased, and feed efficiency improved. Adding solubles to CGM did not improve feed efficiency. Th e feeding value of CGM was similar to distillers grains, suggesting protein has a major role in …

Modifying Different Components Of Distillers Grains And The Impact On Feedlot Performance, Zachary E. Carlson, Curtis J. Bittner, Dirk Burken Burken, Galen E. Erickson, James C. Macdonald
Nebraska Beef Cattle Reports
A finishing study evaluated the effects of altering distillers grains composition on feedlot performance and carcass characteristics. Replacing dried distillers grains with isolated bran, solubles, and protein did not result in performance similar to commodity dried distillers grains. Exchanging bran for non- pelleted treated corn stover increased intake, reduced efficiency, and decreased 12th rib fat. Cattle fed pelleted treated corn stover had decreased intakes, but similar efficiency and gain as non- pelleted treated corn stover. As solubles increased and replaced protein, intakes increased quadratically and 12th rib fat linearly decreased however, all other performance and carcass characteristics were not different.

Feeding Vitamin E May Reverse Sarcoplasmic Reticulum Membrane Instability Caused By Feeding Wet Distillers Grains Plus Solubles To Cattle, Michael D. Chao, Katherine I. Domenech, Chris R. Calkins Calkins
Nebraska Beef Cattle Reports
Steers were finished on either 0% or 30% wet distillers grains plus solubles with four antioxidant treatments (control; vitamin E; Agrado; vitamin E + Agrado). Feeding wet distillers grains plus solubles increased polyunsaturated fatty acids contents in SR membrane and altered sarcoplasmic reticulum phospholipid profiles. Steaks from steers fed wet distillers grains plus solubles also had more protein degradation. Supplementing vitamin E reversed the alteration of sarcoplasmic reticulum phospholipid profiles and prevented the accelerated protein degradation resulted from feeding wet distillers grains plus solubles. These findings suggest that feeding wet distillers grains plus solubles in the finishing diet may accelerate …

Impact Of Feeding Distillers Grains Or Isolated Components In Distillers Grains On Feedlot Performance And Carcass Traits, Brianna B. Conroy, Matt K. Luebbe, Galen E. Erickson Erickson, Jim C. Macdonald, Jacob A. Hansen
Nebraska Beef Cattle Reports
Six treatments were evaluated to determine the contribution of individual components of distillers grains on finishing performance. Diets were formulated to isolate the contribution of solubles, protein, fat, and fiber compared to a diet containing 40% wet distillers grains or a corn- based control. Th ere was a significant improvement in both feedlot and carcass performance in steers fed the 40% wet distillers grains compared to dry- rolled- corn. Numeric differences between fat, fiber, and protein treatments were observed. However, none of the four component diets alone were able to explain the energy value associated with wet distillers grains.

An experiment was conducted to evaluate the influence of individual nutrient components in distillers grains on performance of growing calves. A 40% corn control treatment was included for direct comparison to a diet containing 40% modified distillers grains. Four additional treatments were formulated to isolate the contribution of solubles, protein, fiber, and a combination of fiber and solubles on cattle performance. Average daily gains and ending BW were greater, while F:G lower for cattle fed 40% modified distillers grains compared to the corn control. We were able to determine that protein, when overfed, contributes to the higher energy value of …

Nebraska Beef Cattle Reports
Within the UNL physiology herd, a group of cows have been identified with excess androgen (androstenedione, A4) in their dominant follicle (30 fold higher than controls) and a 17% reduction in calving rate, suggesting subfertility. Th e objective was to identify altered granulosa cell gene expression that could be preventing these cells from converting excess androgen into estrogen. Microarray analysis suggests these granulosa cells experience inhibited proliferation resulting in a reduced total population of cells. Improved understanding of the causes of this phenotype may provide beef producers with tools to identify potentially subfertile cattle and improve reproductive efficiency.

Nebraska Beef Cattle Reports
A budget analysis compared the economics of selling non- pregnant spring- calving cows immediately aft er pregnancy diagnosis or re- breeding non- pregnant cows to be sold as pregnant fall- calving cows in more favorable market prices. Simulation performed for the last 5 yr of market prices demonstrated the strategy is cost effective in different market scenarios, excluding the year 2012/2013. Due to drought, feed prices were the highest and cow prices the lowest of the 5 yr analyzed. Other than atypical scenarios like drought, positive economic results would be possible even at low pregnancy rates, but as the pregnancy …

Accurate Amounts And Nutritive Values Of Corn Residues, Shelby E. Gardine, Andrea K. Watson, Jana L. Harding Harding, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
It is important to have accurate data on the amounts and nutritive values of residues, especially for grazing situations. Ten plants were harvested for each field replication. Statistical analysis suggests 6 to 10 plants are needed to obtain accurate grain yields and accurate amounts of residue. Further laboratory analysis of the leaves and husks suggests that the energy and protein contents of the residue that is consumed is less than previously reported.

Effects Of Different Inoculum Used For In Vitro And In Situ Digestion Procedures Performed On Corn Residue Samples, Hannah C. Hamilton, Jana Harding, Jim C. Macdonald Donald, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
An in vitro and in situ study was conducted to assess the effects of donor diet at time of incubation on NDF digestibility of corn residue samples. Residue samples had greater NDF digestibility when animals were on a similar diet (i.e. a high corn residue diet). Digestibility of NDF was greater when time of incubation increased. Th e diet of the donor steer had greater impact as time of incubation increased implying that the animal’s diet, and incubation time, has an impact on the true values of NDF digestibility.

Effects Of Replacing A Traditional Growing Diet With A Complete Pelleted Feed On Total Tract Digestibility Of Growing Diets, Jana L. Harding, Melissa L. Jolly, Galen E. Erickson Erickson, Jim C. Macdonald
Nebraska Beef Cattle Reports
A digestion study evaluated the effects of replacing traditional growing diets containing 60% untreated corn stover \or 60% alkaline treated corn stover, with one of two types of complete pelleted feeds (Pellet C or Pellet S) containing alkaline treated corn stover and dry distillers grains. Pellet C and S were harvested using different methods. Pellet S had the greatest OM and NDF digestibility, while the untreated stover had the lowest. Pellet C and the treated stover fell intermediate. Replacing a traditional growing diet with a complete pelleted feed resulted in similar or improved diet digestibility, depending on stover harvesting method.
