Nebraska Beef Cattle Reports

Th e impact of three backgrounding systems: grazing corn residue with distillers supplementation at 0.86% BW/d, grazing an oats- brassica forage, or feeding a grower ration in a drylot were evaluated. Calves grazing oats- brassica forage had a greater average daily gain (2.25 lb/d) during the 65 d grazing period than calves grazing corn residue (1.77 lb/d). During the entire growing period (end target weight of 800 lbs) which included 21 days of grower ration for the grazing treatments, gains of calves put directly in the drylot and fed a grower ration (3.58 lb/d) were greater than both grazing treatments …


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 Jan 2016

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.

Nebraska Beef Cattle Reports

A finishing experiment evaluated the effects of harvesting drier corn silage on performance. Factors were corn silage DM (37 or 43%) and inclusion in the finishing diet (15 or 45%). As corn silage inclusion increased, DMI did not diff er, ADG decreased, and F:G increased. As DM of corn silage was increased, no differences in DMI, ADG, or F:G were observed at either 15 or 45% inclusion. Ensiling drier silage increased tonnage with no negative impact on performance.


Effects Of Protein Supplementation In Corn Silage Growing Diets Harvested At 37 Or 43% Dm On Cattle Growth, F. Henry Hilscher, Robert G. Bondurant, Jana L. Harding Harding, Terry J. Klopfenstein, Galen E. Erickson Jan 2016

Nebraska Beef Cattle Reports

A growing study evaluated the effects of harvesting drier corn silage and response to rumen undegradable protein (RUP) supplementation. Corn silage was harvested at 37 or 43% DM from the same fields and protein supplement (high in RUP) was provided at 0.0, 2.5, 5.0, 7.5 or 10.0% of diet DM. Ending BW and ADG were decreased, while F:G was increased, when steers were fed 43% DM silage compared to 37% DM silage (88% silage inclusion). Increasing supplemental RUP in the diet increased ending BW, DMI, and ADG linearly, and decreased F:G linearly. Drier silage had less energy for growing steers …


Use Of Dietary Nitrate Or Sulfate For Mitigation Of Methane Production By Finishing Steers, Anna C. Pesta, Robert G. Bondurant, Samodha C. Fernando Fernando, Galen E. Erickson Jan 2016

Use Of Dietary Nitrate Or Sulfate For Mitigation Of Methane Production By Finishing Steers, Anna C. Pesta, Robert G. Bondurant, Samodha C. Fernando Fernando, Galen E. Erickson

Nebraska Beef Cattle Reports

A finishing study was conducted to evaluate the effects of dietary nitrate and sulfate on methane production in finishing cattle. Both nitrate and sulfate addition decreased DMI and ADG. In diets with no sulfate, addition of nitrate had no impact on emissions, but nitrate and sulfate in combination decreased CH4:CO2. However, neither nitrate nor sulfate had any further impact on methane production. Effect of these compounds may be diet dependent and in this study had little impact on CH4 emissions in finishing cattle.

Two trials (summer and winter) were conducted with 80 steers each at the UNL ARDC near Mead, Neb. Continuous body temperature was collected throughout both trials and blood samples were taken every other week until four weeks prior to harvest. Th is resulted in a total of 6 collections for the summer and 8 collections for the winter. Blood measures responded differently between seasons with significant quadratic interactions between collection time and season suggesting environmental conditions affect blood metabolites.

Nebraska Beef Cattle Reports

Knowledge of producer concerns and perceptions on methane production from cattle and its impact on the environment is unknown. Therefore, the objectives of this survey were to determine what producers know about methane production by cattle and to determine if different age groups, regions of Nebraska, and production size/ type affects producer opinions on enteric methane production and climate change. Producers felt that methane production has little impact on animal performance but were not very confident in their knowledge. Most producers received information related to animal agriculture from veterinarians; therefore, veterinarians should continue to be a major target for extension …

Shackelford, Kristin E. Hales Hales, Tami M. Brown- Brandl, Meredith L. Bremer, Matthew L. Spangler, Tommy L. Wheeler, David A. King, Galen E. Erickson

Nebraska Beef Cattle Reports

A finishing study evaluated the effects of shade and feeding zilpaterol hydrochloride (ZH) on performance, carcass quality, mobility, and body temperature. No effect on body temperature, or performance was observed for shaded cattle versus cattle in open pens. Feeding ZH increased HCW, LM area and decreased yield grade. Zilpaterol hydrochloride increased respiration rate but did not significantly affect body temperature or mobility. Across all treatments mobility decreased with time, therefore, cattle were least mobile at the time of harvest.

Nebraska Beef Cattle Reports

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 Jan 2016

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 Jan 2016

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.

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.

Effects Of Feeding Isolated Nutrient Components In Mdgs On Growing Cattle Performance, Brianna B. Conroy, Curtis J. Bittner, Jim C. Macdonald Donald, Matt K. Luebbe, Galen E. Erickson

Nebraska Beef Cattle Reports

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 …

Granulosa Cell Exposure To Excess Androgens Inhibits Their Ability To Proliferate In The Cow Which May Cause Or Perpetuate Androgen Excess, Andrea S. Cupp, Sarah Romereim, Adam F. Summers Summers, William E. Pohlmeier, Renee M. Mcfee, Renata Spuri- Gomes, Scott G. Kurz, Anthony K. Mcneel, Robert A. Cushman, John S. Davis, Jennifer R. Wood

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.

Economics Of Rebreeding Non- Pregnant Females, Aline G. Da Silva, Jacqueline A. Musgrave, Don C. Adams Adams, John Nollette, Andy Applegarth, Rick N. Funston

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.

Evaluation Of Distillers Grains Components Singly Or In Combination In A Calf Fed Feedlot Study, Rachel A. Oglesbee, Curtis J. Bittner, F. Henry Hilscher Hilscher, Galen E. Erickson, Jim C. Macdonald, Matt K. Luebbe

Nebraska Beef Cattle Reports

A finishing study was conducted to determine the value of the fiber, protein, fat, and solubles components from wet distillers grains plus solubles (WDGS) alone or in combination for feedlot cattle in comparison to WDGS diets. The fiber portion alone did not improve F:G. When protein was included in the composite with fiber, F:G improved. With fat and solubles both added separately, F:G continued to improve. None of the components alone could make up the feeding value of WDGS, however the composite diet of fiber, protein, fat, and solubles combined matched the performance observed when WDGS is fed.
