Implant Programs For Feedlot Heifers Using Synovex® Plus™, Revalor®-H, Or Finaplix®-H With Mga, Casey Macken, Todd Milton, Bill Dicke
Implant Programs For Feedlot Heifers Using Synovex® Plus™, Revalor®-H, Or Finaplix®-H With Mga, Casey Macken, Todd Milton, Bill Dicke
Nebraska Beef Cattle Reports
A commercial feedlot experiment was conducted using 1,558 heifers to evaluate the effects of implant programs on finishing heifers. Implanting with Synovex Plus increased ADG and hot carcass weight compared to heifers implanted with Revalor-H or Finaplix- H and fed MGA. Heifers implanted with either Synovex Plus or Revalor-H had increased DMI compared to heifers implanted with Finaplix-H. Marbling score was influenced by each of the implant treatments, being highest for Finaplix-H followed by Revalor-H and Synovex Plus.
Metabolizable Protein Requirements Of Lactating Two-Year-Old Cows, Tray Patterson, Don C. Adams, Terry J. Klopfenstein, Amelia Hopkin
Metabolizable Protein Requirements Of Lactating Two-Year-Old Cows, Tray Patterson, Don C. Adams, Terry J. Klopfenstein, Amelia Hopkin
Nebraska Beef Cattle Reports
Eighteen lactating two-year-old cows maintained on meadow hay were used to determine the effects of supplementation to meet metabolizable protein or degradable intake protein requirements on production traits during the first two months after calving. Cows supplemented to meet metabolizable protein requirements had a higher ADG than degradable protein supplemented cows. Milk production declined from 15.9 to 10.8 lb/ day at 26 to 69 days after calving, respectively. Hay intake averaged 2.4% of body weight. Supplementation to meet metabolizable protein requirements increased postpartum weight change, but did not affect intake or milk production.
Use Of Sodium Citrate To Enhance Tenderness And Palatability Of Pre-Rigor Beef Muscles, Christian Perversi, Chris R. Calkins, Jesus Velazco
Use Of Sodium Citrate To Enhance Tenderness And Palatability Of Pre-Rigor Beef Muscles, Christian Perversi, Chris R. Calkins, Jesus Velazco
Nebraska Beef Cattle Reports
The objective of this project was to evaluate the response in tenderness and consumer acceptability of three muscles from the chuck that were pumped pre-rigor with different concentrations of sodium citrate solutions to inhibit glycolysis, while maintaining skeletal restraint for 24 hours. Controls were left on carcass, while the other three treatments had the thoracic limb removed and muscles pumped post-mortem to 10% of their weight with solutions of 0 mM, 200 mM or 400 mM sodium citrate. Although tenderness ratings were not always statistically different (comparing controls vs. 400 mM solution), there was a clear trend showing higher concentrations …
Effect Of Fiber Level In Finishing Diets On Diet Digestibility And Corn Silage Impact On Bacterial Crude Protein Production, Kyle Vander Pol, Galen E. Erickson, Ryan Mass, Terry J. Klopfenstein
Effect Of Fiber Level In Finishing Diets On Diet Digestibility And Corn Silage Impact On Bacterial Crude Protein Production, Kyle Vander Pol, Galen E. Erickson, Ryan Mass, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
Two metabolism trials evaluated the impact of dietary fiber source, level, and digestibility on daily production of bacterial crude protein. In the first trial evaluating corn silage, digestibility was unaffected while daily bacterial crude protein production estimated from urinary allantoin excretion tended to be higher as corn silage replaced corn. In the second trial digestibility was significantly lower for the finishing diets containing higher levels of dietary corn bran.
Windrow Grazing And Baled-Hay Feeding Strategies For Wintering Calves, Jerry D. Volesky, Don C. Adams, Richard T. Clark
Windrow Grazing And Baled-Hay Feeding Strategies For Wintering Calves, Jerry D. Volesky, Don C. Adams, Richard T. Clark
Nebraska Beef Cattle Reports
Windrow grazing is a strategy where livestock directly graze windrow-stored forage, generally during a time when packaged hay is provided. We evaluated calf performance, forage quality and waste, and determined economic returns under windrow grazing and bale-fed strategies. Quality of windrow- stored forage remained constant through fall and winter and resulted in adequate calf gains. Forage waste under windrow grazing was closely associated with grazing management. Economic analysis indicated costs for windrow grazing were substantially less than those associated with a bale feeding strategy. Correspondingly, net returns per head and acre were greater for windrow grazing compared to the bale-fed …
Longitudinal Patterns Of Fecal Shedding Of Escherichia Coli O157:H7 By Feedlot Cattle, Spring Younts, David R. Smith, Jeffrey Folmer, Rodney A. Moxley, Suzanne Hinkley, Jeff Gray, Laura Hungerford, Margaret Khaitsa, Terry J. Klopfenstein
Longitudinal Patterns Of Fecal Shedding Of Escherichia Coli O157:H7 By Feedlot Cattle, Spring Younts, David R. Smith, Jeffrey Folmer, Rodney A. Moxley, Suzanne Hinkley, Jeff Gray, Laura Hungerford, Margaret Khaitsa, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
To describe the prevalence, incidence, and duration of fecal shedding of E. coli O157:H7, 99 feedlot steers were individually tested each week of the feeding period for presence of E. coli O157:H7 in rectal feces. E. coli O157:H7 was recovered from each animal at least once during the study. Both the incidence and mean duration of shedding peaked during the middle of the feeding period. The percentage of cattle shedding E. coli O157:H7 ranged from 1% to 80% over the course of the feeding period and was affected by both the incidence and the duration of shedding.
The Effects Of Marination And Cook Cycles On High And Low Ph Beef Muscles, Ryan Baumert, Roger W. Mandigo
The Effects Of Marination And Cook Cycles On High And Low Ph Beef Muscles, Ryan Baumert, Roger W. Mandigo
Nebraska Beef Cattle Reports
Infraspinatus and Serratus ventralis, the muscles of the high pH group, had lower shear force values and higher sensory analysis scores for tenderness, juiciness and overall acceptability than low pH muscles (Deep pectoral and Biceps femoris). Increasing the phosphate level in the marination system increased moisture content of the cooked roast and sensory juiciness scores and decreased the cooking loss of the roasts. Low humidity cookery had higher sensory juiciness, tenderness and acceptability scores and lower cooking losses than high humidity cookery. The Infraspinatus and Serratus ventralis are recommended for use in a marination system with low humidity cookery.
Weaning Date For Spring Calving Cows Grazing Sandhills Range, Lane Ciminski, Don C. Adams, Terry J. Klopfenstein, Dick Clark, Andy Applegarth, Jacqueline A. Musgrave, Russ Sandberg
Weaning Date For Spring Calving Cows Grazing Sandhills Range, Lane Ciminski, Don C. Adams, Terry J. Klopfenstein, Dick Clark, Andy Applegarth, Jacqueline A. Musgrave, Russ Sandberg
Nebraska Beef Cattle Reports
A two-year experiment was conducted with March calving cows to determine the effect of the weaning date on cow body condition score, cow body weight, and calf body weight. Treatments were of eight weaning dates imposed at consecutive two-week intervals, beginning in mid-August and ending in late November. Cow body condition score declined linearly as weaning date was later in the fall. Calf body weight gains from August through November increased with weaning dates from August 18 through October 13; however, weaning after October 13 provided no advantage of increased calf body weight gain.
Effect Of Altered Feeding And Sprinkling On Performance And Body Temperature Of Steers Finished In The Summer, Shane Davis, Terry L. Mader
Effect Of Altered Feeding And Sprinkling On Performance And Body Temperature Of Steers Finished In The Summer, Shane Davis, Terry L. Mader
Nebraska Beef Cattle Reports
Effects of feeding time (800 vs 1400) and sprinkling on feedlot performance, body temperature, and mound microclimate were examined to determine their usefulness in reducing heat stress of feedlot steers. Feed conversion was improved overall for steers with access to sprinklers. Body temperature, early in the finishing period, was reduced by both sprinkling and afternoon feeding relative to steers fed at 800 h without access to sprinklers . Overall water intake was greater for steers fed at 800 without sprinkling than any other treatment.

Economic Analysis Of Calf Versus Yearling Finishing, D. J. Jordon, Terry J. Klopfenstein, Todd Milton, Rob Cooper, Tony Scott, Galen E. Erickson, Richard T. Clark
Nebraska Beef Cattle Reports
The objective of this report was to compare economics of calf- and yearling- finishing systems. Yearling steers were wintered at 1.54 lb/day (fast) or 0.42 lb/day (slow) then grazed over the summer followed by finishing. Calf-fed steers were purchased in the fall and finished. Profit was based on 1992 to 1999 average price levels. Steers on the fast treatment profited $21.00/head compared to -$20.66/head for slow and -$23.18/head for calf feds. Calf-feeding was also compared to only the finishing phase of yearling systems. Steers on the fast system profited $29.78/head compared to $17.83 for slow and -$23.18 for calf feds.

Subsequent Summer Forage Intake Following Winter Gain Restriction, D. J. Jordon, Dale Downs, Galen E. Erickson, Don C. Adams, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
Data were collected to determine effect of winter gain on forage intake and summer and finishing performance of yearling steers. Steers wintered at reduced gains compensated 17 and 48% over two years. Intake, as a percentage of body weight, was increased for compensating steers. Steers gaining faster in winter had a reduced break even ($67.01 vs 70.05/cwt) and were more profitable ($5.79 vs -31.32/ head) compared to slower gaining steers. Growing animals at faster (1.50 - 1.65 lb/day) compared to slower (0.45 - 0.55 lb/day) rates of winter gain is superior unless 65%-70% compensation is achieved.

Effects Of Rumensin Level During An Acidosis Challenge, Trey Patterson, Todd Milton, Galen E. Erickson, Terry J. Klopfenstein, M. Blackford, Cal Parrott
Effects Of Rumensin Level During An Acidosis Challenge, Trey Patterson, Todd Milton, Galen E. Erickson, Terry J. Klopfenstein, M. Blackford, Cal Parrott
Nebraska Beef Cattle Reports
Eighteen ruminally cannulated steers were used to determine effects of Rumensin level on incidence and severity of acidosis when an acidosis challenge was imposed. Steers received a high-concentrate finishing diet containing either 0, 30, or 45 grams/ton Rumensin. An acidosis challenge was created by feeding only 50% of diet intake one day followed by 175% of intake the next day, four hours post normal feeding time. Feeding Rumensin decreased feed intake during the prechallenge, challenge and acidosis recovery phase. Compared to 30 grams/ ton, feed intake was decreased by increasing Rumensin to 45 grams/ton during the five days following the …
Supplementing Yearling Summer Grazing Cattle With Fat And Protein And Subsequent Feedlot Performance, Ivan G. Rush
Supplementing Yearling Summer Grazing Cattle With Fat And Protein And Subsequent Feedlot Performance, Ivan G. Rush
Nebraska Beef Cattle Reports
Yearling steers supplemented with protein (40% - 29% NPN - 19% from biuret) while grazing primarily crested wheat grass in the summer gained at a faster rate than control steers which were only provided a commercial salt/ mineral mix. A lower level of protein (20% - 6.7% NPN)/fat (15% -20%) combination supplement also increased gain over controls, but the supplement response was less than the higher protein supplement. Gain responses were greater during the latter part of the grazing season when forage quality was poorest. Supplementation intake varied but tended to be greater during the latter part of the grazing …
Forage Quality And Animal Performance Of Steers Grazing Smooth Bromegrass/Legume Pastures, Mark Ullerich, Terry J. Klopfenstein, Bruce Anderson, Michael Trammell
Forage Quality And Animal Performance Of Steers Grazing Smooth Bromegrass/Legume Pastures, Mark Ullerich, Terry J. Klopfenstein, Bruce Anderson, Michael Trammell
Nebraska Beef Cattle Reports
A trial was conducted to evaluate effects of interseeding legumes into smooth bromegrass pastures on animal performance and forage quality. Animal gains on legume/bromegrass treatments were higher than bromegrass alone. Laboratory analysis of diet samples collected from ruminally fistulated steers indicated no difference in the undegradable intake protein content of pastures. Legume/bromegrass treatments had higher IVDMD than the control. Therefore, the increases in gain are attributed to increased energy of legume/bromegrass diets and not undegradable protein content.
Effect Of Sawdust Or Acid Application To Pen Surfaces On Nitrogen Losses From Open-Dirt Feedlots, John Lory, Julie Adams, Bahman Eghball, Terry J. Klopfenstein, J. F. Powers
Effect Of Sawdust Or Acid Application To Pen Surfaces On Nitrogen Losses From Open-Dirt Feedlots, John Lory, Julie Adams, Bahman Eghball, Terry J. Klopfenstein, J. F. Powers
Nebraska Beef Cattle Reports
Two nutrient management treatments (sawdust or sulfuric acid application to pen surface) were compared to conventional management using 12 pens (10 steers/pen) to determine effects on performance and nitrogen losses from pens. Performance and carcass characteristics for treatments were similar to the control. The sawdust treatment retained more nitrogen in manure when removed from the pen surface and after composting. Increasing carbon by sawdust additions reduced nitrogen losses by 21%. Applying acid to the pen surface did not affect quantity of nitrogen or organic carbon conserved in manure and compost.
Undegradable Intake Protein Supplementation Of Compensating, Grazing Steers, Kelly Creighton, Mark Ullerich, Terry J. Klopfenstein
Undegradable Intake Protein Supplementation Of Compensating, Grazing Steers, Kelly Creighton, Mark Ullerich, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
A trial was conducted to evaluate the effect of previous winter gain on response to undegradable intake protein (UIP) supplementation during the summer grazing period. Steers wintered at the FAST rate of gain had a greater response to UIP supplementation than steers with SLOW rate of gain. Maximum response for FAST cattle occurred at 150 g/d of supplemental UIP, while SLOW cattle showed no response through 150 g/d. Forage DM intake was similar for FAST and SLOW cattle, therefore SLOW cattle consumed more as a percentage of body weight. Increased gains from UIP supplementation were not maintained during the finishing …

June Versus March Calving For The Nebraska Sandhills: Production Traits, Don C. Adams, Dick Clark, Russ Sandberg, Gordon Carriker, Terry J. Klopfenstein, Todd Milton
Nebraska Beef Cattle Reports
Our objective was to determine if labor and purchased inputs could be reduced and profitability improved by matching lactation (i.e., calving date) with nutrient content of grazed forages to extend the grazing season in beef cow/calf systems. By adjusting a traditional March calving date to a nontraditional June calving date, nearly 2 tons of harvested feed/cow was replaced by grazing. Feeding and calving labor inputs of mature cows were 61% lower for the June calving compared to the March calving system. Weaning rates were comparable between March and June calving systems. Weaning weights for June-born calves were 70 lbs lighter …

June Versus March Calving For The Nebraska Sandhills: Economic Risk Analysis, Gordon Carriker, Dick Clark, Don C. Adams, Russ Sandberg
Nebraska Beef Cattle Reports
Price risk analysis of economic and financial net returns from June and March calving systems was used to rank and identify preferred production/sale strategies according to risk preferences of producers. Analysis of economic net returns identified selling a June-born steer at weaning from the breeding on meadow (meadow-bred) treatment as preferred strategy regardless of risk preferences. Post-weaning, selling a June-born finished yearling steer from the meadow-bred treatment was ranked highest. Analysis of financial net returns identified selling a June-born yearling steer from the meadow-bred treatment prior to summer grazing as preferred for all but those strongly risk averse; selling a …

June Versus March Calving For The Nebraska Sandhills: Economic Comparisons, Gordon Carriker, Dick Clark, Don C. Adams, Russ Sandberg
Nebraska Beef Cattle Reports
Costs and returns of June and March calving systems were compared at four production phases. Financial costs of the June system were lowest, due primarily to lower costs of producing a weaned calf. Post-weaning financial and economic costs at each phase were nearly identical. Selling June-born steer calves at January weaning would double net returns compared to selling March-born steer calves at October weaning due to lower costs and higher market prices. Net returns for June-born steer calves retained beyond weaning are highest if calves are retained as yearlings and finished. Calves finished as calf-feds provided the highest net returns …
High Moisture And Dry-Rolled High-Oil Corn For Finishing Feedlot Steers, Wanda Cerkoney, Terry L. Mader, Fred Owens
High Moisture And Dry-Rolled High-Oil Corn For Finishing Feedlot Steers, Wanda Cerkoney, Terry L. Mader, Fred Owens
Nebraska Beef Cattle Reports
Finishing steers fed diets containing dry-rolled high-oil corn had a 2.5% reduction in dry matter intake and 4.2% better feed efficiency than steers fed diets containing dry-rolled normal corn. Hot carcass weight, dressing percent, liver abscess score, rib fat thickness, marbling score and yield grade did not differ among treatments. Steers fed high-moisture high-oil corn had larger ribeye area and greater percent kidney, pelvic and heart fat than steers fed high moisture normal corn. No differences in performance or efficiency were detected from substituting high-oil high moisture corn for normal high moisture corn.

Effects Of Feeding Regimen On Performance, Behavior And Body Temperature Of Feedlot Steers, Shane Davis, Terry L. Mader, Wanda Cerkoney
Nebraska Beef Cattle Reports
One hundred forty-four predominantly Angus x Charolais steers were used to determine effects of different feeding regimens on performance, behavior and tympanic temperatures of steers under environmental heat stress. Steers were assigned to one of three treatments: 1) ad libitum fed at 0800 hr (ADLIB); 2) fed at 1600 hr with bunks slick by 0800 hr (BKMGT); and 3) fed 85% of predicted DMI at 1600 hr (LIMFD). Treatments were imposed for 23 days after which all steers were allowed ad libitum access to feed at 0800 hr. Overall performance was not affected by treatment. Altering feed time and amount …
Phosphorus And Nitrogen-Based Beef Cattle Manure Or Compost Application To Corn, Bahman Eghball
Phosphorus And Nitrogen-Based Beef Cattle Manure Or Compost Application To Corn, Bahman Eghball
Nebraska Beef Cattle Reports
This study was conducted to evaluate effects of P and N-based manure and compost applications on corn yield and soil P level. Annual or biennial manure or compost application resulted in corn grain yields similar to those with chemical fertilizer application. P-based manure or compost application resulted in similar corn grain yield but significantly less soil P build-up than N-based treatments. Estimated N availability was 40% for manure and 15% for compost in the first year and was 18% for manure and 8% for compost in the second year after application.
Composting Of Feedlot And Dairy Manure: Compost Characteristics And Impact On Crop Yields, Galen E. Erickson, Terry J. Klopfenstein, Walker Luedtke, Mark Schroeder, Charles A. Francis, Gary Lesoing
Composting Of Feedlot And Dairy Manure: Compost Characteristics And Impact On Crop Yields, Galen E. Erickson, Terry J. Klopfenstein, Walker Luedtke, Mark Schroeder, Charles A. Francis, Gary Lesoing
Nebraska Beef Cattle Reports
Since 1993, approximately 17,600 tons of beef feedlot and dairy compost have been spread on 1,100 acres. Crop yields were measured to determine the impact of a one-time compost application by using no-compost check strips in large-scale production fields. Adding compost to irrigated corn, irrigated soybeans, and dryland corn acres significantly increased yields, with four-year average increases of 2.3, 1.5, and 2.7%, respectively. For all crops measured, the response to compost was greatest the first year following application and declined linearly in subsequent years. The increased yield from compost application offsets spreading costs using average prices for crops.
Impact Of Grazing Corn Stalks In The Spring On Crop Yields, Galen E. Erickson, Terry J. Klopfenstein, D. J. Jordon, Walker Luedtke, Gary Lesoing
Impact Of Grazing Corn Stalks In The Spring On Crop Yields, Galen E. Erickson, Terry J. Klopfenstein, D. J. Jordon, Walker Luedtke, Gary Lesoing
Nebraska Beef Cattle Reports
A two-year experiment was designed to determine the impact of grazing corn residue during the spring on subsequent soybean yields in a corn-soybean rotation. Tillage treatments consisting of ridge-till, fall-till, spring-till, and no-till were also evaluated to determine if yields could be maintained by alleviating compaction from grazing in the spring. Grazing treatments overall, and specifically in the ridge-till and no-till systems, resulted in increased yields. Residue cover was also more sensitive to changes in tillage rather than grazing; however, both treatments decreased residue cover.

The Effects Of Post-Harvest Time And Temperature On Glycolytic Potential Of Beef Muscle, Dana J. Hanson, Chris R. Calkins
Nebraska Beef Cattle Reports
The objectives of this study were to determine if post mortem temperature affects extent of glycogen metabolism and if sampling time influences glycolytic potential values in muscle. Beef longissimus muscles entered rigor mortis at two different temperatures and were sampled at 45 minutes post mortem, rigor mortis and 24 hours post mortem to determine the glycolytic potential of the muscle. Post mortem temperature had little effect on the glycolytic potential of beef muscle. Glycolytic potential values from samples removed early post mortem were underestimated when compared to samples taken at 24 hours post mortem.
Compensatory Growth And Slaughter Breakevens Of Yearling Cattle, D. J. Jordon, Terry J. Klopfenstein, Todd Milton, Rob Cooper
Compensatory Growth And Slaughter Breakevens Of Yearling Cattle, D. J. Jordon, Terry J. Klopfenstein, Todd Milton, Rob Cooper
Nebraska Beef Cattle Reports
A two-year summary of growing/ finishing systems indicates that steer calves wintered at 1.5 lb/day had lower slaughter breakeven (P < .05) costs compared to animals wintered at 0.5 lb/day. Additionally, feeding wet corn gluten feed as an energy source to increase winter gains tended (P < .15) to produce slaughter breakevens which were lower than the same winter gains produced by feeding corn. Restricting animal gain over the winter (0.5-1.0 lb/day) resulted in 25-32% compensation on grass compared to controls (1.5 lb/day). Comparison of calf finishing vs. yearling growing/finishing systems showed that steers wintered with a “fast” rate of gain (1.5 lb/day) profited $28.85/head compared to losses by steers wintered with a “slow” rate of gain (0.5 lb/day; $-30.24/head) or calf finishing ($-20.87/head).

Consumer Acceptance And Value Of Strip Steaks Differing In Marbling And Country-Of-Origin, K. M. Killinger, W. J. Umberger, Chris R. Calkins, Kent M. Eskridge, D. Feuz
Nebraska Beef Cattle Reports
Consumers (72.6%) visually preferred low marbled steaks. However, high marbled steaks were rated more juicy, tender and desirable in flavor and overall acceptability than low marbled steaks. Based on auction bids, consumers in Chicago (but not San Francisco) were willing to pay more for high marbled steaks than low marbled steaks. Domestic steaks were rated higher in all sensory attributes than Argentine steaks. Consumers in both locations were willing to pay more for domestic steaks than Argentine steaks. Although most consumers visually prefer low marbled steaks, most consumers find high marbled steaks to be more acceptable in sensory characteristics.

Influence Of Restricted Intake And Reduced Dietary Starch On Colonic Ph And E. Coli Prevalence, Tim Loy, Casey Wilson, Doreen Baily, Terry J. Klopfenstein, Rodney A. Moxley, David R. Smith, Spring Younts
Nebraska Beef Cattle Reports
Ninety feedlot steers were used to test the effects of reducing dietary starch and intake on colonic pH, VFA, total and acid-resistant coliform and E. coli populations, and E. coli O157:H7 shedding. When corn bran and wet corn gluten feed (WCGF), or high moisture corn and WCGF were substituted for dry rolled corn, colonic pH increased while VFA concentration decreased. The corn bran and WCGF diet reduced acid-resistant E. coli shedding. Restricting intake increased colonic pH and decreased VFA concentration, but did not affect acid-resistant E. colishedding. Prevalence of E. coliO157:H7 was not affected by diet or intake.
