Comparison Of Traditional And Alternative Curing Ingredients On Curing Reactions In A Model Meat System, Faith D. Rasmussen, Gary A. Sullivan Jan 2019

Comparison Of Traditional And Alternative Curing Ingredients On Curing Reactions In A Model Meat System, Faith D. Rasmussen, Gary A. Sullivan

Nebraska Beef Cattle Reports

To meet consumer trends, alternative curing ingredients are used to replace sodium nitrite and cure accelerators. Due to the complexity of meat, it is challenging to compare traditional and alternative ingredients for curing reactions. Using a model system, sources of nitrite (traditional, sodium nitrite and alternative, cultured celery juice powder), salt, and cure accelerators (traditional, sodium erythorbate, or alternative, cherry juice powder) at ingoing sodium nitrite concentrations of 10, 50, 100, 150, or 200 ppm were evaluated for curing reactions. More complete curing reactions were indicated by a higher concentration of cured meat pigment, and lower sulfhydryl groups. Lower residual ...


Evaluation Of Lactation Demands On Nutrient Balance In Two Calving Seasons In Range Cows Grazing Sandhills Upland Range, Travis Mulliniks, Don C. Adams Jan 2019

Evaluation Of Lactation Demands On Nutrient Balance In Two Calving Seasons In Range Cows Grazing Sandhills Upland Range, Travis Mulliniks, Don C. Adams

Nebraska Beef Cattle Reports

A modeling study evaluated the effects of milk production level on nutrient balance in March-and May-calving cows grazing Sandhills upland range during the breeding season. Forage quality of upland range peaks in June and steadily declines in July until November. In March-calving cows, metabolizable protein (MP) and energy were deficient by July 1 in all milking potential cows, which is exacerbated in greater milking potential cows. May-calving cows with 20 to 30 lbs of milk are predicted to enter the breeding season with a deficiency in MP and energy. In an effort to match cow type to environment in the ...


Economic Analysis Of Beef Systems, Terry J. Klopfenstein, Shebly E. Loeffelholz, Karla H. Jenkins Pas, Andrea K. Watson, Galen E. Erickson Jan 2019

Economic Analysis Of Beef Systems, Terry J. Klopfenstein, Shebly E. Loeffelholz, Karla H. Jenkins Pas, Andrea K. Watson, Galen E. Erickson

Nebraska Beef Cattle Reports

Economic analysis of complete beef production systems is important. An analysis of 5 systems was conducted. Three of the systems were based on cows calving in March, June or August and grazing Sandhills range and corn residue. The other 2 systems were based on complete confinement feeding or confinement in the summer and corn residue grazing in the winter. The range-based systems gave similar results, however, complete confinement was not competitive. Partial confinement with stalk grazing was competitive with range-based systems. Stalk grazing is very economical and important for many cow-calf systems.


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 Jan 2019

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 ...

Evaluation Of Corn Bran Plus Solubles On Performance And Carcass Characteristics In Finishing Diets, Shelby A. Garland, Bradley M. Boyd, F. Henry Hilscher Hilscher, Galen E. Erickson, Jim C. Macdonald, Ryan A. Mass

Nebraska Beef Cattle Reports

A finishing study was conducted to determine the effect of feeding corn bran plus solubles, a new feed resulting from a pre-fermentation fiber removal process, compared to wet distillers grains plus solubles at two levels of inclusion (20% and 40% of diet DM). Intake increased with inclusion of byproduct, and steers fed 20% wet distillers had the greatest intakes numerically. Byproduct inclusion, regardless of type, increased daily gain over the corn-based control. Feed conversions were improved with increased inclusion of both Bran + Solubles and wet distillers, and both were superior to the control. Increased inclusion of both byproducts resulted in ...


A Comparison Of Synovex One® Alone To Synovex Choice® Followed By Synovex Plus® As Implant Strategies For Finishing Heifers, Elizabeth A. Schumacher, Galen E. Erickson, D. J. Jordon Jordon, Robert J. Cooper, Tony L. Scott, Sheri Bundy, Gary Sides, Ralph M. Cleale Jan 2019

A Comparison Of Synovex One® Alone To Synovex Choice® Followed By Synovex Plus® As Implant Strategies For Finishing Heifers, Elizabeth A. Schumacher, Galen E. Erickson, D. J. Jordon Jordon, Robert J. Cooper, Tony L. Scott, Sheri Bundy, Gary Sides, Ralph M. Cleale

Nebraska Beef Cattle Reports

A commercial feedlot study utilizing 1,737 crossbred heifers (initial BW 690 lb) compared the effect of two implant strategies [Synovex ONE Feedlot (day 0) or Synovex Choice (day 0) followed by Synovex Plus (day 95)] on performance and carcass characteristics. No differences were observed in carcass weight, final body weight, or gain, but heifers implanted with Synovex ONE Feedlot had slightly greater feed conversion and greater intake than heifers implanted using Synovex Choice/Synovex Plus. Heifers implanted with Synovex Choice/Synovex Plus had lower marbling score and yield grade, higher dressing percentage, and greater loin muscle area compared to ...


Impact Of Shade In Beef Feedyards On Performance, Body Temperature, And Heat Stress Measures, Brett A. Melton, Bradley M. Boyd, Casey Macken Macken, Andrea K. Watson, James C. Macdonald, Galen E. Erickson Jan 2019

Nebraska Beef Cattle Reports

A study using crossbred steers was conducted at a commercial feedyard to determine the effects of pen shades on cattle performance, body temperature, and cattle activity. Two heat events (Event 1 and Event 2) and one cool event were defined for the feeding period. No significant differences were observed for average daily gain, dry matter intake, feed to gain, or carcass characteristics at the end of the trial. During Event 1, cattle in pens with shade had lower panting scores than cattle in open pens. During Event 2, cattle in shade pens had greater dry matter intake, lower panting scores ...


Effects Of Maternal Late Gestation Nutrition On May-Born Steer Progeny, Alicia C. Lansford, Jacki A. Musgrave, T. L. Meyer Meyer, Rick N. Funston Jan 2019

Effects Of Maternal Late Gestation Nutrition On May-Born Steer Progeny, Alicia C. Lansford, Jacki A. Musgrave, T. L. Meyer Meyer, Rick N. Funston

Nebraska Beef Cattle Reports

May-calving dams were assigned to graze either sub-irrigated meadow or upland range with or without supplementation (1 lb/d 33% CP). Treatment began at approximately 160 d of gestation. Supplementation continued for 85 ± 2 d, while grazing system treatment continued for 116 ± 2 d. Steer progeny were backgrounded after weaning and then assigned to either a short or long yearling feedlot system. Dam supplementation tended to decrease marbling score within both feedlot systems. Short yearling steers had an increased percentage of carcasses grade USDA low Choice or greater if their dams grazed meadow in late gestation. Long yearling steers had ...


Pooled Analysis Of Individually Fed Finishing Trials, Brett A. Melton, James C. Macdonald, Andrea K. Watson Watson, Galen E. Erickson Jan 2019

Pooled Analysis Of Individually Fed Finishing Trials, Brett A. Melton, James C. Macdonald, Andrea K. Watson Watson, Galen E. Erickson

Nebraska Beef Cattle Reports

A pooled analysis of 21 finishing trials (2002–2016; 1530 animals) with cattle individually fed in Calan gate barns was conducted. Mixed model regression analysis following random coefficient methodology was used to evaluate relationships between performance variables and carcass characteristics. Gain had a greater effect on efficiency (R2 = 0.72) compared to intake (R2 = 0.02). The relationship between gain and efficiency was cubic, while intake had a quadratic relationship. The cubic response of gain relative to efficiency was continually increasing with relatively slight curves in the line heavily influenced by points that lay on the ends of ...


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 Jan 2019

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.


Nitrate Concentrations Of Annual Forages Grown For Grazing In Nebraska, Mary E. Lenz, Rebecca J. Kern, Carrie E. Orvis Orvis, Mary E. Drewnoski Jan 2019

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 ...


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 Jan 2019

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.


The Effect Of Cow Udder Score On Subsequent Calf Performance In The Nebraska Sandhills, Joslyn K. Beard, Jacki A. Musgrave, Rick N. Funston Funston, J. Travis Mulliniks Jan 2019

The Effect Of Cow Udder Score On Subsequent Calf Performance In The Nebraska Sandhills, Joslyn K. Beard, Jacki A. Musgrave, Rick N. Funston Funston, J. Travis Mulliniks

Nebraska Beef Cattle Reports

Cow records were evaluated over a 5-yr period to investigate how cow udder score affected calf growth and carcass performance. Cows from 2 calving herds, March and May, were classified as bad or good based on udder scores recorded at calving. Calves suckling dams with bad udders performed similarly during the pre-weaning period to good udder counterparts, with no differences in overall steer feedlot performance between udder groups. However, steers suckling good udder cows had heavier carcass weights and greater back fat thickness.


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 Jan 2019

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.


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 Jan 2019

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.


Impact Of Cow Size On Cow-Calf And Subsequent Steer Feedlot Performance, Molly Benell, Jacki A. Musgrave, Rick N. Funston Funston, J. Travis Mulliniks Jan 2019

Impact Of Cow Size On Cow-Calf And Subsequent Steer Feedlot Performance, Molly Benell, Jacki A. Musgrave, Rick N. Funston Funston, J. Travis Mulliniks

Nebraska Beef Cattle Reports

This study retrospectively evaluated the effect of cow size on cow-calf performance and post-weaning steer feedlot performance of cows at the Gudmundsen Sandhills Laboratory, Whitman. Cows were categorized at small, medium, or moderate within cow age from 13 years of data. Small cows had decreased reproductive performance, weaned smaller calves, and produced steer progeny with smaller carcass weights. In this dataset and under the environmental and management conditions at Gudmundsen Sandhills Laboratory, overall productivity of the cowherd decreased as cow size decreased with 1,150 to 1,200 lb cow being the most productive cow size.


Effect Of Adding Urea To Finishing Diets Containing Two Different Inclusions Of Distillers Grains On Steer Performance And Carcass Characteristics, Bradley M. Boyd, James C. Macdonald, Matthew K. Luebbe Luebbe, Galen E. Erickson Jan 2019

Effect Of Adding Urea To Finishing Diets Containing Two Different Inclusions Of Distillers Grains On Steer Performance And Carcass Characteristics, Bradley M. Boyd, James C. Macdonald, Matthew K. Luebbe Luebbe, Galen E. Erickson

Nebraska Beef Cattle Reports

The effects of adding urea to a dry rolled corn based finishing diet containing low inclusions of distillers grains was evaluated. Treatments were designed as a 2 × 4 factorial arrangement with factors consisting of wet distillers inclusion (either 12 or 20% of diet DM) and urea inclusion (0, 0.4, 0.8, 1.2% of diet DM). There were no significant interactions observed between distillers inclusion and urea inclusion in the diet. Increasing inclusion of distillers grains improved carcass adjusted average daily gain and feed conversion and reduced dry matter intake. Increasing distillers inclusion also increased 12th rib fat and ...


Evaluation Of Fractionated Distillers Grains (High Protein And Bran Plus Solubles) On Performance And Carcass Characteristics In Finishing Diets, Shelby A. Garland, Bradley M. Boyd, F. Henry Hilscher Hilscher, Galen E. Erickson, Jim C. Macdonald, Ryan A. Mass Jan 2019

Evaluation Of Fractionated Distillers Grains (High Protein And Bran Plus Solubles) On Performance And Carcass Characteristics In Finishing Diets, Shelby A. Garland, Bradley M. Boyd, F. Henry Hilscher Hilscher, Galen E. Erickson, Jim C. Macdonald, Ryan A. Mass

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 ...


Effects Of Maternal Late Gestation Nutrition On May-Born Heifer Progeny, Alicia C. Lansford, Jacki A. Musgrave, Rick N. Funston Funston Jan 2019

Effects Of Maternal Late Gestation Nutrition On May-Born Heifer Progeny, Alicia C. Lansford, Jacki A. Musgrave, Rick N. Funston Funston

Nebraska Beef Cattle Reports

May-calving dams in late gestation grazed either sub-irrigated meadow with or without supplement or upland range with or without supplement. Supplementation was 1 lb/d of a 33% CP (DM) supplement. Heifer progeny from these dams were followed through their first and second breeding seasons. Both dam grazing and supplement treatment affected heifer progeny BW and BCS. Heifers born to dams who grazed meadow in late gestation attained a greater percentage of mature BW at the start of their first breeding season and increased pregnancy rates as primiparous cows. Grazing of meadow by May-calving dams in late gestation may increase ...


Effects Of Backgrounding And Feedlot System Strategies On May-Born Steer Performance, Alicia C. Lansford, Jacki A. Musgrave, T. L. Meyer Meyer, Rick N. Funston Jan 2019

Effects Of Backgrounding And Feedlot System Strategies On May-Born Steer Performance, Alicia C. Lansford, Jacki A. Musgrave, T. L. Meyer 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 ...


Corn Oil Supplementation On Performance And Methane Production In Finishing Steers, Tommy M. Winders, Brad M. Boyd, Henry F. Hilscher Hilscher, Samodha C. Fernando, Rick R. Stowell, Galen E. Erickson Jan 2019

Corn Oil Supplementation On Performance And Methane Production In Finishing Steers, Tommy M. Winders, Brad M. Boyd, Henry F. Hilscher Hilscher, Samodha C. Fernando, Rick R. Stowell, Galen E. Erickson

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 ...


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 Jan 2019

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 ...


Prediction Of Energy Value (Tdn) In Grazed And Hayed Forages, Terry J. Klopfenstein, Mary E. Drewnoski, Karla H. Jenkins Jenkins Jan 2019

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 ...


Effects Of Prepartum Nutrition On May-Calving Cows And Progeny, Alicia C. Lansford, Jacki A. Musgrave, T. L. Meyer Meyer, Rick N. Funston Jan 2019

Effects Of Prepartum Nutrition On May-Calving Cows And Progeny, Alicia C. Lansford, Jacki A. Musgrave, T. L. Meyer Meyer, Rick N. Funston

Nebraska Beef Cattle Reports

May-calving dams grazed either sub-irrigated meadow or upland range from Jan. 5 to May 1 each year for 6 years. Within grazing system, dams received either no supplement or 1 lb/d of a 33% CP supplement from Jan. 5 to April 1. Dams grazing meadow in the prepartum period weighed more and had a greater body condition score prior to calving. They also tended to have greater pregnancy rates in the subsequent breeding season and tended to wean heavier calves than dams grazing upland range. Allowing May-calving dams to graze meadow in late gestation may increase herd profitability through ...

Nebraska Beef Cattle Reports

A 2 × 3 factorial digestion study evaluated three corn silage hybrids and kernel processing for finishing steers. The three hybrids included a control corn silage, a brown midrib, and a brown midrib with a softer endosperm. Both brown midrib hybrids had greater fiber digestibility than the traditional control corn silage hybrid. No differences were observed between brown midrib hybrids for all other nutrients. Cattle fed brown midrib hybrids had a lower average ruminal pH compared to the control suggesting more fermentation, but no differences in volatile fatty acid concentration or proportions. Kernel processing had no effect on apparent total tract ...
