Nebraska Beef Cattle Reports
A finishing study evaluated the effect of feeding a new, high protein distillers grains along with corn bran plus condensed distillers solubles compared to traditional wet distillers grains, traditional dry distillers grains and a corn-based control. Each byproduct replaced corn at 40% of the diet dry-matter. Intake was not affected by treatment; however gain and carcass weight were greater and feed conversion improved for high protein distillers and corn bran plus solubles than either type of traditional distillers grains or corn. Based on feed efficiency, the feeding values of high protein distillers grains and corn bran plus solubles are 121% …

Impact Of Grazing Spring Rye On Subsequent Crop Yields And Profitability, Ashley C. Conway, Robert G. Bondurant, Fred H. Hilscher Hilscher, Jay Parsons, Daren Redfearn, Mary E. Drewnoski
Nebraska Beef Cattle Reports
Steers (729 ± 19 lb BW) grazed in two November-planted cereal rye fields for 22 d in April, either with or without an ionophore in their free choice mineral supplement. Subsequent corn yields were measured to assess impact of planting cereal rye as a cover crop (not grazed) or grazing the rye compared to a no rye control. There was no statistical impact of rye or grazing on subsequent corn yield. Supplying an ionophore in the mineral did not uniformly improve gains across fields. However, gains were high at 3.2 lb/d and were able to offset the cost of planting …

Economics Of Field Pea Supplementation For Cattle Grazing Crested Wheatgrass, Braden C. Troyer, Hannah L. Greenwell, Andrea K. Watson Watson, James C. Macdonald, Karla H. Jenkins
Nebraska Beef Cattle Reports
Heifers grazing crested wheat grass were supplemented either field peas or dried distillers grains plus solubles (DDGS) at 0.4% or 0.8% of body weight. Heifers supplemented with field peas had 10% lower daily gain compared to their DDGS supplemented counterparts. The decision to supplement field peas for producers depends on the price at which field peas can be acquired, as well as the distance that DDGS has to be hauled in order to be utilized. Field peas are a viable option in western Nebraska as a supplement for grazing cattle when DDGS is unavailable or field peas are in excess …

Effects Of Backgrounding And Feedlot System Strategies On May-Born Steer Performance, Alicia C. Lansford, Jacki A. Musgrave, T. L. Meyer, Rick N. Funston
Nebraska Beef Cattle Reports
May-born steers were backgrounded to achieve either a high or low rate of gain. The high rate of gain was achieved by offering steers meadow hay ad libitum and 4 lb/d of a 33% CP (DM) supplement, while the low rate of gain consisted of steers grazing meadow and offered 1 lb/d of the same supplement. After backgrounding, one-half of the steers from each group entered the feedlot in May as short-yearlings, while the remainder grazed upland range until entering the feedlot as long-yearlings in mid-September. Hot carcass weight was greater for steers backgrounded to achieve a high rate of …

Effects Of Varying Levels Of Silage Inclusion And Brown Midrib Corn Silage On Finishing Performance Of Steers, Lauren A. Ovinge, F. Henry Hilscher, Brad M. Boyd Boyd, John N. Anderson, Galen E. Erickson
Nebraska Beef Cattle Reports
A 2 × 3 factorial finishing study evaluated traditional or brown midrib corn silage fed at three inclusions in finishing diets. Silage inclusion was 15%, 45%, or 75% inclusion (DM basis) for 70 days followed by 15% inclusion for the remainder of the finishing phase. Cattle were ultrasounded twice to calculate backfat deposition rate for a target backfat of 0.55 inches, as cattle were fed longer if silage inclusion was 45 or 75/15%. Cattle fed 45% or 75/15% silage inclusion had greater final body weight (BW) and days on feed, but higher feed:gain (F:G) than cattle fed 15% silage. Daily …
Impact Of Corn Silage Inclusion On Nutrient Digestion And Rumen Fermentation In Finishing Cattle, Hannah C. Hamilton, Melissa L. Jolly-Breithaupt, Andrea K. Watson Watson, Jim C. Macdonald, Galen E. Erickson
Impact Of Corn Silage Inclusion On Nutrient Digestion And Rumen Fermentation In Finishing Cattle, Hannah C. Hamilton, Melissa L. Jolly-Breithaupt, Andrea K. Watson Watson, Jim C. Macdonald, Galen E. Erickson
Nebraska Beef Cattle Reports
A digestion study was conducted comparing different inclusions of corn silage used as a roughage source on digestibility, feeding behavior and rumen environment. Treatments consisted of 3 inclusions of corn silage at 0, 7.5 and 15% of the diet DM, and a control treatment with 7.5% alfalfa. As expected, increasing available energy and decreasing roughage (either silage or alfalfa) showed an increase in diet digestibility and ruminal propionate concentrations. However, average ruminal pH was least, with more time spent in subacute acidosis (pH < 5.3) when cattle were fed no roughage. These data suggest that feeding cattle increasing silage inclusions as a roughage source prevented ruminal conditions from entering and remaining in subacute acidosis. Feeding corn silage at 15% gave similar digestibility responses compared to 7.5% alfalfa. Including silage as a roughage source at 15% could help prevent acidosis and digestive upset in feedlot cattle.

Nebraska Beef Cattle Reports
A finishing trial was conducted to evaluate the effects of corn oil on animal performance, carcass characteristics, and methane production in finishing cattle. Corn oil was supplemented at 3% of the diet (dry matterbasis) and led to a decrease in intake, a numerical improvement in average daily gain, and improved feed efficiency compared to the control cattle. Dry matter intake while in the methane barn was not decreased between treatments, although it was numerically similar to what was observed outside of the methane barn. Corn oil did not affect any carcass parameters. Methane production (g/d) was reduced with the inclusion …

Nebraska Beef Cattle Reports
Two metabolism studies were conducted to evaluate the effects of biochar (0, 0.8, or 3% of diet dry matter) on digestibility and methane production in growing and finishing diets. Intake was not affected by biochar inclusion in the growing diet and increased with 0.8% biochar inclusion in the finishing study. Digestibility tended to increase quadratically with biochar inclusion in the growing study while digestibility tended to linearly decrease with biochar inclusion in the finishing study. Methane production (g/d) decreased 10.7% in the growing study and 9.9% in the finishing study with 0.8% biochar compared to no biochar. Methane production was …
Three Year Summary: Comparison Of Diets Collected From Esophageally Fistulated Cows To Forage Quality Estimated From Fecal Analysis, Bethany M. Johnston, Jay D. Jenkins, Jacki A. Musgrave Musgrave, J. Travis Mulliniks, Mitchell B. Stephenson, James C. Macdonald, L. Aaron Stalker
Three Year Summary: Comparison Of Diets Collected From Esophageally Fistulated Cows To Forage Quality Estimated From Fecal Analysis, Bethany M. Johnston, Jay D. Jenkins, Jacki A. Musgrave Musgrave, J. Travis Mulliniks, Mitchell B. Stephenson, James C. Macdonald, L. Aaron Stalker
Nebraska Beef Cattle Reports
Inconsistency was found in forage quality (crude protein and energy) when esophageally fistulated diets were compared to Nutrition Balance Analyzer (NUTBAL) analysis of fecal samples. On upland range sites, hand-clipping of samples (not a recommended practice to measure forage quality), was closer to fistulated diets than NUTBAL analysis. If cattle managers are solely utilizing NUTBAL for estimates of forage value, incorrect supplemental energy and protein decisions will likely be made resulting in the purchase of unnecessary supplements, thereby reducing the profitability of the operation.

Prediction Of Energy Value (Tdn) In Grazed And Hayed Forages, Terry J. Klopfenstein, Mary E. Drewnoski, Karla H. Jenkins Jenkins
Nebraska Beef Cattle Reports
The goal of producers and nutritionists is to meet the nutritional needs of their cattle. Requirements are well established, but the diets of grazing cattle are difficult to predict. Selection by the animal, sample handling, lab analysis, and relating the lab analysis to the animal are issues that have been researched the last 20 years. Based on that research, data have been compiled to predict the energy and protein values of grazed Sandhills range, meadows, smooth brome, and corn residue. Additionally, equations used by commercial labs to predict the TDN of grass hays based on ADF were compared to TDN …

Nitrate Concentrations Of Annual Forages Grown For Grazing In Nebraska, Mary E. Lenz, Rebecca J. Kern, Carrie E. Orvis Orvis, Mary E. Drewnoski
Nebraska Beef Cattle Reports
Annual forage samples sent by producers to Ward Laboratories Inc. for nitrate analysis were evaluated to determine which cover crop species in Nebraska are most likely to accumulate nitrates, and how often the accumulated nitrates are considered toxic by traditional recommendations. Additionally, nitrate levels of cover crop mixes grown in research trials were analyzed to ensure species differences were repeated when grown together in the same fields. Brassicas accumulate more nitrate than small grains, millet, sorghum/sudan grasses, or cover crop mixes. Brassicas accumulated levels of nitrate considered moderately to highly toxic in 48% of the samples. The other cover crop …

Effect Of Rapeseed Inclusion In Late-Summer Planted Oats Pasture On Growing Performance Of Beef Steers, Hannah E. Riley, Kristin E. Hales, Steven D. Shackelford Shackelford, Harvey C. Freetly, Mary E. Drewnoski
Nebraska Beef Cattle Reports
Fall cover crops have been shown to be an effective way to background calves into the winter. An oat monoculture was planted in late summer at 100 lb/ac and compared to oats planted at 50 lb/ac with rapeseed included at 3 lb/ac. Initial forage yield was not affected by the inclusion of rapeseed with fall oat. Calf gain tended to be greater and cost of gain was decreased when rapeseed was included. Including rapeseed in late summer planted oats may be beneficial for producers who want to graze growing calves in the fall.

Effects Of Supplemental Soypass In Forage-Based Diets Containing Distillers Grains On Performance Of Growing Steers, Tyler J. Spore, Zachary E. Carlson, Galen E. Erickson Erickson, Terry J. Klopfenstein, Andrea K. Watson
Nebraska Beef Cattle Reports
SoyPass was supplemented in two grass hay diets containing 20% or 35% wet distillers grains with solubles (WDGS) to analyze the effects on growing cattle performance. The SoyPass supplement replaced 0, 30, or 60% of dietary WDGS for a total of 6 treatments with a factorial design. Substituting SoyPass into the diet did not affect average daily gain (ADG) of calves; however, calves consuming the 35% WDGS diet gained 31% more than the 20% WDGS treatment calves. Dry matter intake (DMI) and feed to gain (F:G) increased linearly in the 35% WDGS diet with the inclusion of SoyPass. In the …

Effects Of Isolated Nutrients In Distillers Grains On Total Tract Digestibility And Digestible Energy In Forage Diets, Tasha M. King, Melissa L. Jolly-Breithaupt, Hannah C. Hamilton Hamilton, Galen E. Erickson, Jim C. Macdonald
Nebraska Beef Cattle Reports
A digestion study was conducted to evaluate the contribution of individual nutrient components of distillers grains on nutrient digestibility and digestible energy. All diets contained 56% brome hay with a control diet containing either 40% corn; or 40% modified distillers grains. Four additional diets compared the contribution of fat, protein, fiber, and solubles components of distillers grains. No differences were observed for digestibility of DM, OM, and NDF among treatments. Feeding the isolated protein resulted in similar digestible energy to modified distillers grains, suggesting the bypass protein component contributes heavily to energy in distillers.
