Late Summer Planted Oat-Brassica Forage Quality Changes During Winter Grazing, Mary E. Lenz, Jordan L. Cox, Kristin E. Hales Hales, Hannah C. Wilson, Mary E. Drewnoski
Nebraska Beef Cattle Reports
Oat, radish, and turnip samples were taken on pivots being grazed from November through January in Clay Center, Nebraska. The objective was to determine how the quality changed throughout the winter. The forage was observed to be high-quality (highly digestibility with moderate CP content). Digestibility did decline over this period but minimal changes in CP content were observed. From early November to early January, the digestibility of oats appeared to decline more (10% unit decline) than turnip and radish leaves (5% unit decrease). However, digestibility (67% IVOMD) and CP content (15%) of oats in early January were still as high …

Comparison Of Two Alternate Prostaglandin Products In Yearling Beef Heifers, Alicia C. Lansford, Tonya L. Meyer, Richard N. Funston Funston
Nebraska Beef Cattle Reports
Yearling heifers were administered 1 of 2 alternate prostaglandin products (Lutalyse vs. Lutalyse HighCon), which differ in concentration of active ingredient and administration route. Timing of estrus, pregnancy rate to AI, and final pregnancy rate did not differ between treatments. Body weight and ADG were also not affected by prostaglandin treatment. These results indicate producers can utilize Lutalyse HighCon, administered subcutaneously (s.c.), to avoid injection site blemishes and reduce carcass discounts with no impact on estrus synchronization or pregnancy rates.

Steer Performance Grazing Corn Residue And Supplemented With Modified Distillers Grains Plus Solubles With Or Without Urea, Robert M. Jones, Robby G. Bondurant, F. Henry Hilscher Hilscher, Jim C. Macdonald
Nebraska Beef Cattle Reports
A growing study was conducted to evaluate the effects of supplementing growing calves grazing corn residue with modified distillers grains plus solubles (MDGS; 3 or 5 lb/d) and with or without urea on growth performance. There were no significant MDGS × urea inclusion interactions observed. Urea inclusion level (0 and 0.12 lb/d) did not affect supplemental intake, ADG, or ending BW. Steers fed 5 lb of MDGS had an increased ADG and a heavier ending BW compared to steers fed 3 lb MDGS daily. Supplemental urea is not necessary when supplementing at least 3 lb MDGS to steers grazing corn …

The Relationship Between Marbling, Superoxide Dismutase, And Beef Tenderness, Nicolas J. Herrera, Emery K. Wilkerson, Katherine I. Domenech-Perez Perez, Felipe A. Ribeiro, Michael D. Chao, Chris Calkins
Nebraska Beef Cattle Reports
This study was conducted to evaluate the relationships between animal oxidative status (as indicated by superoxide dismutase [SOD] activity) to marbling and beef tenderness. Prime and Select-grade strip loins were selected and aged for 2, 7, 14, 21, and 28 days for Warner Bratzler shear force, Troponin-T, and SOD activity. Results showed that meat exhibiting higher levels of marbling had lower shear force values and thus were more tender. Low-marbled samples tended to have a greater tenderness response to aging. The effect of oxidative stress, however, was not evident in this study as SOD values were similar. Although the effects …

Evaluation Of Corn Distillers Solubles On Growing Steer Performance, Benjamin H. Hansen, Robert G. Bondurant, F. Henry Hilscher Hilscher, Galen E. Erickson, Jim C. Macdonald
Nebraska Beef Cattle Reports
A growing study evaluated increasing inclusions of corn distillers solubles (CDS) at 10, 20, 30, and 40%, or increasing wet distillers grains plus solubles (WDGS) at 10, 20, 30, and 40% compared to a corn control. Corn was replaced by CDS or WDGS in each forage-based diet. Increasing CDS resulted in a quadratic increase for both DMI and F:G. Increasing WDGS linearly increased both DMI and ADG with no effect on F:G. The energy value of CDS is less than that of corn, whereas WDGS had an energy value similar to corn in growing diets with 50% brome hay. A …

Effect Of Myoglobin State On Color Stability Of High Pressure Processed Ground Beef, Jhinuk Gupta, Chad G. Bower, George A. Cavender Cavender, Gary A. Sullivan
Nebraska Beef Cattle Reports
High pressure processing, a non-thermal pasteurization technique, can reduce E. coli in beef but the use is limited due to discoloration of raw beef after high pressure processing. Different states of myoglobin have inherently different color stability. The objective of this study was to determine the impact of myoglobin state on color stability of raw beef patties treated with high pressure processing. Modified atmosphere packaging (high oxygen-oxymyoglobin, carbon monoxide-carboxymyoglobin), vacuum packaging (deoxymyoglobin) or added potassium ferricyanide (metmyoglobin) treatments were used to prepare patties with desired myoglobin states. Color was measured (CIE L*, a*, b*) before and after high pressure processing …

Effect Of Ingredients And Packaging On Color Of High Pressure Processed Ground Beef, Jhinuk Gupta, Chad G. Bower, George A. Cavender Cavender, Gary A. Sullivan
Nebraska Beef Cattle Reports
High pressure processing is a non-thermal pasteurization technique to control pathogens, like E. coli. However, color changes in raw beef induced by processing restrict high pressure processing’s use within the beef industry. The objectives of this study were to investigate the effects of adding curing agents (nitrite) and packaging with or without reducing compounds (ascorbic acid/erythorbate) on color retention in high pressure processed ground beef. High pressure processing resulted in a detrimental effect on the color of the beef patties for all treatments. Lightness and yellowness increased and redness decreased after high pressure processing. The effect remained the same throughout …

Effects Of Production System On Cow And Calf Performance, Shelby E. Gardine, Jason M. Warner, Robert G. Bondurant Bondurant, F. Henry Hilscher, Karla H. Jenkins, Galen E. Erickson, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
Limited traditional forage resources have prompted interest for alternative cow-calf production systems. This study evaluated the effects of two winter cow-calf production systems (cornstalk grazing and dry-lot feeding) on cow-calf performance in a summer-calving, intensively managed cowherd at two locations. Grazing cow-calf pairs on cornstalks resulted in similar or lower ending BW of cows and lower ADG of calves when compared to cow-calf pairs wintered in the dry-lot. A partial budget of incorporating winter cornstalk grazing into an intensive production system suggests that cows wintered on cornstalks may be $137 more profitable compared to cows wintered in the dry-lot.

Nebraska Beef Cattle Reports
This study evaluated the effects of cow-calf production system and post-weaning management on finishing performance and carcass characteristics of steer and heifer calves. Calves that were wintered on cornstalks prior to weaning had lighter initial BW compared to calves that were wintered in the dry-lot; however, final BW and carcass weight were similar between treatments. Post-weaning management was either adapting calves to a finishing diet following weaning or feeding a grower diet prior to the finishing phase. When harvested at similar back fat, calves that were fed a grower diet for 76 days prior to the finishing phase had 71 …

The Effect Of Harvest Method And Ammoniation Of Corn Residue On Growing Calf Performance, Ashley C. Conway, Robert G. Bondurant, F. Henry Hilscher Hilscher, James C. Macdonald, Terry J. Klopfenstein, Mary Drewnoski
Nebraska Beef Cattle Reports
A growing trial was conducted to determine the effect of feeding baled corn residue harvested using three different methods, with and without ammoniation of the residue. Residue harvested with the New Holland Cornrower™ with two rows of chopped stem added to the windrow resulted in a 9% increase in ADG compared to conventional rake and bale harvest or turning off the combine spreader and baling tailing. Ammoniation of residue increased ADG 67% (increase of 1.1 lb/d) over non-ammoniated residue. Feed efficiency was not affected by harvest method, but ammoniation decreased F:G by 13% compared to cattle fed non-ammoniated residue. Although …

A metabolism trial was conducted to evaluate protein from modified distillers grains plus solubles (MDGS) in finishing diets on nutrient digestibility and ruminal fermentation characteristics. Isolated protein from corn was not different than MDGS for dry matter, organic matter, or neutral detergent fiber digestibility. However, steers fed MDGS tended to have lower total tract organic matter digestibility compared to corn and protein from corn. Protein had greater total tract organic matter and starch digestibility than MDGS. Protein from corn did not contribute towards the lower digestibility of MDGS. Protein is more easily digestible than the other components in distillers grains …

Nebraska Beef Cattle Reports
This study was conducted to evaluate some sources of potential variation in determination of longissimus muscle area between the 12th and 13th ribs of carcasses from heifers fed with or without zilpaterol hydochloride. Cross sections of the rib-loin were taken cranial to the 11th rib and caudal to the 13th rib, about 3–4 millimeters thick at 90 degrees perpendicular to the long axis of the longissimus muscle. Potential variation of longissimus muscle area can arise from the natural variation of muscle size when cutting between the 12th and 13th ribs (up to 9%). Deviation in cutting perpendicular to the long …
