The purpose of dry aging is to develop novel favors and other sensory characteristics different from wet aged meat. However, leaving meat exposed to air for an extended period of time can have negative effects on meat quality. As the meat is exposed to oxygen for an extended period of time, lipids are oxidized resulting in compounds that negatively affect favor. In this study, oxygen concentration was regulated along with time, temperature, humidity, and air flow. The purpose of oxygen regulation was to determine the effect of oxidation on the quality, specifically flavor preference, of dry aged meats. Sensory analysis …
Economic Analysis Of Increased Corn Silage Inclusion In Beef Finishing Cattle, Hannah C. Wilson, J. C. Macdonald, Andrea K. Watson, Terry Klopfenstein, Galen E. Erickson
Economic Analysis Of Increased Corn Silage Inclusion In Beef Finishing Cattle, Hannah C. Wilson, J. C. Macdonald, Andrea K. Watson, Terry Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
An economic analysis was conducted to assess the feasibility of feeding greater inclusions of corn silage in finishing diets. Cattle were fed two inclusions of corn silage (15 and 45% of diet dry matter) with or without tylosin. Cattle fed 15% corn silage with tylosin had the best feed conversion, 15 % corn silage without tylosin was intermediate, and both 45% corn silage with and without tylosin had the poorest feed conversion. Feeding corn silage at greater inclusions decreased ADG but increased final body weight when fed to an equal fatness (28 days longer). However, feeding corn silage at 45% …
Impact Of Days Fed On Holstein Bull And Steer Performance And Cutability Of Cattle Pen- Fed Organic Diets, Elizabeth A. Schumacher, Braden C. Troyer, Bradley M. Boyd, Levi Mcphillips, J. C. Macdonald, Andrea K. Watson, Terry Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports
Performance, carcass characteristics, and total meat yield of Holstein bulls and steers were compared in a simulated organic production system with the goal of producing ground beef. Holstein bulls (n = 120, initial BW = 487 lb) and steers (n = 120, initial BW = 471 lb) of the same age were blocked by BW and assigned randomly to be harvested at 308, 343, 378, and 413 days on feed. After harvest, all meat o" the carcass was considered trim and was collected and weighed to calculate total trim yield. Bulls gained faster and had greater live body weight, carcass …
Training Improves The Reliability Of Temperament Assessment In Cattle, Jamie T. Parham, Jessica J. Schmidt, Ronald M. Lewis
Training Improves The Reliability Of Temperament Assessment In Cattle, Jamie T. Parham, Jessica J. Schmidt, Ronald M. Lewis
Nebraska Beef Cattle Reports
Accurate and precise measurement of docility in cattle is paramount when including temperament as a criterion for selection. The value of training individuals in assigning a docility score was evaluated by comparing the reliability of individual assessments of temperament in beef cattle before and after various instructional methods. Preceding training, participants’ assessment of cattle behavior, videoed while each heifer was restrained in a chute, was not impacted by age, gender, or pre- existing cattle handling experience. Groups of participants that received additional training were more accurate and precise in evaluating temperament, regardless of training method, compared to those without. No …
Mineral Concentrations Of Forages For Livestock In Nebraska And South Dakota, Rebecca J. Kern, John W. Kern, Hannah M.G. Dorn, Carrie E. Putnam, Janna J. Block, Adele A. Harty, M. E. Drewnoski
Mineral Concentrations Of Forages For Livestock In Nebraska And South Dakota, Rebecca J. Kern, John W. Kern, Hannah M.G. Dorn, Carrie E. Putnam, Janna J. Block, Adele A. Harty, M. E. Drewnoski
Nebraska Beef Cattle Reports
Forage samples from Nebraska and South Dakota submitted to Ward Laboratories, Inc. from 2012– 2019 were analyzed for mineral concentrations. Samples were categorized by forage species, quality based on protein content, and mineral concentration based on requirements for lactating beef cows. ! e data indicate that copper and zinc are frequently deficient across all species and levels of forage quality, emphasizing the need for supplementation. Except for magnesium, macro- mineral deficiencies are less likely to occur when feeding high quality forages in Nebraska and South Dakota. Corn feedstuffs are particularly likely to result in mineral deficiencies if fed without mineral …
Evaluation Of Models Used To Predict Dry Matter Intake In Forage- Based Diets, Aksel Wiseman, Andrea K. Watson, Rick Stock, Terry Klopfenstein

Nebraska Beef Cattle Reports
Accurately predicting intake is critical to model performance of cattle in order to formulate diets to meet nutritional requirements. Modeling systems must be accurate in order to provide correct information to producers. Multiple studies with growing cattle consuming forage- based diets were summarized. Actual gain and weights of the cattle were used to determine predicted dry matter intake using the Beef Cattle Nutrient Requirements Model (2016). ! e predicted dry matter intakes were compared to observed dry matter intakes to determine accuracy of the prediction model. ! e model over predicted intakes at low TDN and under predicted intakes at …
Winter Growth Rate And Timing Of Marketing On Economics Of Yearling Systems, Michael Merical, M. E. Drewnoski, Jay Parsons
Winter Growth Rate And Timing Of Marketing On Economics Of Yearling Systems, Michael Merical, M. E. Drewnoski, Jay Parsons
Nebraska Beef Cattle Reports
Economic analyses were conducted examining 18 years of Nebraska monthly- average auction data to ! nd the e" ects of certain management decisions on the pro! tability of yearling production systems. A 2×2 experimental design was used to examine four possible scenarios. $ e variables were either fast winter growth (daily gain, 2.0 lb/ day) or slow winter growth (daily gain, 0.8 lb/day), and either a September or a July marketing date. In addition to pro! tability, risk management was also examined in this study. Average pro! tability of all scenarios was good, ranging from $112 to $143 per calf. …

Nebraska Beef Cattle Reports
A digestion study was conducted to evaluate Masters Choice corn silage hybrids on nutrient digestibility in growing beef steers. ! e three hybrids evaluated were a conventional hybrid (CON) commonly grown in Eastern Nebraska which served as the control, Masters Choice hybrid MCT6365 RIB (MC1) that has been selected to improve " ber and starch digestion and Masters Choice hybrid MCT6733 GT3000 (MC2) selected to improve " ber digestion. Treatment diets consisted of 80% of the diet dry matter (DM) of each corn silage hybrid. Steers fed MC1 corn silage had the greatest organic matter (OM), energy digestibility, and digestible …
