Nebraska Beef Cattle Reports
Over half of Nebraska’s ethanol plants are removing oil from distillers grains via centrifugation of the thin stillage constituent. Removing oil by this method does not impact intake or total tract digestibility in beef cattle growing diets. However, increasing the concentration of de-oiled distillers grains in the diet significantly improved intake and digestibility. Thus, concentration of distillers grain in the diet has a greater impact on total tract digestibility than the fat content in forage-based diets.
Effect Of 300 Or 400 Mg Daily Of Ractopamine Hydrochloride On Growth Performance And Carcass Characteristics Of Finishing Steers During The Last 14, 28, Or 42 Days, Curtis J. Bittner, Dirk B. Burken, Adam L. Shreck Shreck, James C. Macdonald, Galen E. Erickson, Nathan A. Pyatt
Effect Of 300 Or 400 Mg Daily Of Ractopamine Hydrochloride On Growth Performance And Carcass Characteristics Of Finishing Steers During The Last 14, 28, Or 42 Days, Curtis J. Bittner, Dirk B. Burken, Adam L. Shreck Shreck, James C. Macdonald, Galen E. Erickson, Nathan A. Pyatt
Nebraska Beef Cattle Reports
The effects of ractopamine hydrochloride (Optaflexx®) dosage (0, 300, and 400 mg/head/day) and duration (14, 28, or 42 days) on growth performance were evaluated in feedlot finishing diets. Feeding 300 mg of Optaflexx for 28 or 42 days increased live final BW by 13 and 29 lb, while feeding Optaflexx at 400 mg resulted in 27 or 24 lb increases relative to 0 mg steers, respectively. Feeding 300 mg of Optaflexx for 28 or 42 days would suggest 11.1 or 16.6 lb improvements in HCW, while feeding 400 mg of Optaflexx would suggest 19.7 or 20.7 lb heavier carcasses compared …
Genetic Parameter Estimates For Calving Difficulty And Birth Weight In A Multibreed Population, Cashley M. Ahlberg, Larry A. Kuehn, R. Mark Thallman Thallman, Stephen D. Kachman, Matthew L. Spangler
Genetic Parameter Estimates For Calving Difficulty And Birth Weight In A Multibreed Population, Cashley M. Ahlberg, Larry A. Kuehn, R. Mark Thallman Thallman, Stephen D. Kachman, Matthew L. Spangler
Nebraska Beef Cattle Reports
Eighteen breeds were utilized to estimate genetic parameters for birth weight and calving difficulty on first-parity females. Birth weight and calving difficulty were moderately heritable allowing for genetic selection to decrease calving difficulty. Genetic correlation estimates were positive between direct effects for birth weight and calving difficulty. This work will serve as the foundation for estimating across-breed EPD for calving difficulty in the U.S.

Nebraska Beef Cattle Reports
Four experiments were conducted comparing wet or dry distillers grains plus solubles to each other or to corn as an energy source in forage-based diets. Diets included dry distillers grains plus solubles, wet distillers grains plus solubles or dry-rolled corn, with sorghum silage, grass hay and supplement. Data were pooled to generate ADG at differing inclusions allowing energy value of wet distillers grains plus solubles to be calculated relative to dry-rolled corn. The energy value of distillers grains plus solubles fed at 15% of diet DM was 137% and fed at 30% of the diet DM was 136% relative to …

Mineral Composition Of Serial Slaughter Holstein Carcasses, Andrea K. Watson, Trent J. Mcevers, Lee-Anne J. Walter Walter, Nathan D. May, Jacob A. Reed, N. Andy Cole, Ty E. Lawrence, James C. Macdonald, Galen E. Erickson
Nebraska Beef Cattle Reports
Carcasses of 115 Holstein steers were divided into lean, bone, internal cavity, hide, and fat tissues for analysis of P, Ca, K, Mg, and S retention. Every 28 days, five steers from each of two treatments, fed Zilmax for 20 days prior to harvest or not fed Zilmax, were harvested. There were no differences due to treatment or days on feed when mineral retention was expressed as g/100 g of protein gain. Expressing mineral retention relative to protein gain reduced variation due to rate of gain and animal size.

Supplementing Cow-Calf Pairs Grazing Smooth Bromegrass, Jason M. Warner, Annie J. Doerr, Galen E. Erickson Erickson, Rick J. Rasby, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
A three-year study evaluated supplementing ethanol co-products mixed with low-quality forage to cow-calf pairs grazing smooth bromegrass as a method to replace grazed forage intake. Supplementing a 30:70 modified distillers grains plus solubles:cornstalks mixture reduced estimated grazed forage intake by approximately 40%. Doubling the stocking rate and supplementing did not impact cow or calf performance. A summer supplementation program designed to reduce grazed forage intake is a viable strategy for increasing stocking rate if forage for grazing is limited.
Digestibility Of Calcium Oxide Treated Corn Residue With De-Oiled Distillers Grains, Sarah J. Peterson, Meredith L. Bremer, Adam L. Shreck Shreck, James C. Macdonald, Galen E. Erickson
Digestibility Of Calcium Oxide Treated Corn Residue With De-Oiled Distillers Grains, Sarah J. Peterson, Meredith L. Bremer, Adam L. Shreck Shreck, James C. Macdonald, Galen E. Erickson
Nebraska Beef Cattle Reports
A digestion study was conducted to evaluate diets containing calcium oxide treated corn residue in combination with de-oiled distillers grains in forage based growing diets. Chemical treatment did not affect digestibility of DM, OM, or NDF. However, concentration of distillers grains did improve DM and OM digestibility. The use of chemically treated residue in combination with distillers grains in growing diets may not impact diet digestibility.
Effects Of Dietary Fat Source And Monensin On Methane Emissions, Vfa Profile, And Performance Of Finishing Steers, Anna C. Pesta, Andrea K. Watson, Robert G. Bondurant Bondurant, Samodha C. Fernando, Galen E. Erickson
Effects Of Dietary Fat Source And Monensin On Methane Emissions, Vfa Profile, And Performance Of Finishing Steers, Anna C. Pesta, Andrea K. Watson, Robert G. Bondurant Bondurant, Samodha C. Fernando, Galen E. Erickson
Nebraska Beef Cattle Reports
A finishing study was conducted to evaluate the effects of dietary fat source and presence or absence of monensin on performance, methane (CH4) emissions, and ruminal VFA profile of cattle. No effects on performance or VFA profile were observed. Inclusion of modified distillers grain plus solubles (MDGS) in the diet tended to increase measures of CH4 production when compared to other fat sources (corn oil or tallow), while inclusion of monensin in the finishing diet was not significant for CH4 production.

Nebraska Beef Cattle Reports
Nebraska Sandhills subirrigated meadow pastures were used to measure the effects of grazing on forage nutrient content in summer pastures. Non-grazed pastures had greater diet CP content than grazed pastures early in the grazing season. By late July, grazed vs. non-grazed pastures did not differ in diet CP content. Non-grazed pastures had greater in vitro organic matter disappearance compared with grazed pastures from late July through September; however, early summer pastures were not affected. Observed results indicate the greatest differences in nutrient content between grazed and non-grazed meadow pastures occur early and late in the grazing season when the majority …

Evaluation Of Changes In Nutritional Quality Of Corn Residue Over Time, Mandi Jones, James C. Macdonald, Terry J. Klopfenstein Klopfenstein, Galen E. Erickson, Keith Glewen, Andrea K. Watson
Nebraska Beef Cattle Reports
Irrigated corn residue was sampled across time in order to determine changes in quality and proportion of corn residue as the plant dried and was exposed to effects of weathering. Corn plants from two hybrids were planted on two different planting dates and harvested at periodic intervals from August 2012 to December 2012. Proportions of stem, blade/sheath, husk/shank, and cob made up smaller components of total plant DM as it matured, with the largest relative reduction occurring in the blade/sheath or stem. Hybrid impacted TDN values primarily because the 119 day hybrid was less mature at the early sampling dates.

Nebraska Beef Cattle Reports
A metabolism trial was conducted to determine the effects of corn oil removal in condensed distillers solubles (CDS) and modified distillers grains plus solubles (MDGS) on nutrient digestibility and ruminal pH. Oil removal had no impact on DM, OM, or NDF digestibility in steers fed CDS or MDGS. However, steers fed de-oiled CDS had a lower fat digestibility than steers fed normal CDS. Average ruminal pH was lower for steers fed de-oiled MDGS than for steers fed normal MDGS, however no difference within CDS was observed.

Nebraska Beef Cattle Reports
Yearling steers rotationally grazing smooth bromegrass were individually supplemented monensin at 0 or 200 mg with modified distillers grains plus solubles (MDGS) at .05, 0.4, 0.6, and 0.8% BW. Cannulated steers continuously grazing smooth bromegrass were assigned randomly to one of two treatments: 0.4% BW MDGS supplementation with 0 or 200 mg monensin. Monensin did not affect ADG of steers supplemented MDGS ≥ 0.4% BW. Steers supplemented with monensin had a decreasein estimated average forage intakefrom 16.16 lb to 14.75 lb/OM daily.

Nebraska Beef Cattle Reports
A metabolism study was conducted to evaluate the effects of supplementing a fibrolytic enzyme (Enspira™) on total tract digestion of a finishing diet. In situ NDF digestibilities of the corn bran, HMC, corn residue, and corn silage were not different between the treatments. Rate of digestion of the corn residue and corn silage was lower for the enzyme treatment compared to the control. Averageruminal pH was not significantly different between the two treatments. Correspondingly, there was no difference in VFA profile. There were no differences in DM, OM, NDF, ADF, or hemicellulose digestibilities between the control and enzyme treatment.

Effects Of Replacing Corn With A Pelleted Treated Corn Stover And Distillers Grains On Performance Of Finishing Cattle, Jana L. Harding, Curtis J. Bittner, Dirk B. Burken Burken, Galen E. Erickson, James C. Macdonald
Nebraska Beef Cattle Reports
A finishing study evaluated the effectsof replacing 10, 20, or 30% corn (DM basis) with pelleted treated corn stover and distillers grains in a diet containing either 20 or 40% modified distillers grains plus solubles (MDGS) on finishing cattle performance. Steers consuming 10, 20, or 30% of the pelleted feed with 40% MDGS had equal or similar performance to the control diet with 40% MDGS. Cattle consuming 10% pelleted feed with 20% MDGS had similar efficiencies as the control diet; however, feeding the pellet at 20 or 30% of the diet DM with 20% MDGS decreased feed efficiency.
Feeding Value Of De-Oiled Wet Distillers Grains Plus Solubles Relative To Normal When Fed With Either Dry-Rolled Corn Or Steam-Flaked Corn In Beef Finishing Diets, Meredith L. Bremer, Marie E. Harris, Jake A. Hansen Hansen, Karla H. Jenkins, Matt K. Luebbe, Galen E. Erickson
Feeding Value Of De-Oiled Wet Distillers Grains Plus Solubles Relative To Normal When Fed With Either Dry-Rolled Corn Or Steam-Flaked Corn In Beef Finishing Diets, Meredith L. Bremer, Marie E. Harris, Jake A. Hansen Hansen, Karla H. Jenkins, Matt K. Luebbe, Galen E. Erickson
Nebraska Beef Cattle Reports
A 128-day finishing study utilized 328 yearling steers to determine the effects of feeding de-oiled wet distillers grains plus solubles (WDGS) in dry rolled corn (DRC) or steam-flaked corn (SFC) diets relative to normal fat WDGS. No significant interactions were observed, but cattle fed DRC had greater DMI and were less efficient than those consuming SFC. Linear improvements in ADG and F:G were observed as concentration of de-oiled WDGS increased from 0 to 35%. Numerically cattle fed normal WDGS were more efficient than cattle fed de-oiled WDGS.

Response To Increasing Concentrations Of De-Oiled Modified Distillers Grains Plus Solubles In Beef Feedlot Diets, Meredith L. Bremer, Curtis J. Bittner, Dirk B. Burken Burken, Galen E. Erickson, James C. Macdonald
Nebraska Beef Cattle Reports
A 154-day finishing study, utilizing 378 calf-fed steers, was conducted to evaluate the response to feeding increasing concentrations of de-oiled modified distillers grains plus solubles (MDGS) on cattle performance and carcass characteristics. Two additional diets were fed to compare de-oiled MDGS to normal MDGS at either 15 or 30% inclusion. Increasing concentration of de-oiled MDGS in the diet resulted in a linear improvement in F:G. When comparing 30% de-oiled to normal MDGS, there was a tendency for 3.4% improvement in F:G for cattle fed normal MDGS diets over those fed de-oiled MDGS.
