Corn Residue Removal Effects On Subsequent Yield, Brian J. Wienhold, Gary E. Varvel, Virginia L. Jin Jin, Rob B. Mitchell, Kenneth P. Vogel

Nebraska Beef Cattle Reports

Corn residue is used for forage and feed, but residue removal effects on soil properties and yield is a concern. Residue removal effects on corn yields and soil organic carbon is site specific. Removing 50% of the residue from rain fed sites reduced corn yield by 1.9 bu/ac, whereas removing 40% of the residue from irrigated sites increased corn yield by 15.4 bu/ac. However, removing 53% of the residue increased soil erosion by 30%. Agronomic practices such as reduced tillage, cover crops, or manure may offset residue removal impacts. Residue removal should be based on site-specific characteristics and management, but …

Nitrogen Fertilization And Ddgs Supplementation Reduces Annual Weeds In Pastures, John A. Guretzky, Laura K. Snell, John C. Soper Soper, Walter H. Schacht, Terry Klopfenstein, Stephanie K. Pruitt

Nebraska Beef Cattle Reports

Ongoing research has found body weight (BW) gains of steers supplemented with corn dried distillers grains plus solubles (DDGS) on unfertilized smooth bromegrass pasture (SUPP) to be greater than unsupplemented steers on N fertilized (FERT) and unfertilized, control (CONT) smooth bromegrass pasture. In the seventh year of the study, annual weeds increased to 20%, 9%, and 2% of relative cover within CONT, SUPP, and FERT pastures, respectively. Supplementation of DDGS on unfertilized pastures improves steer BW gains and reduces N inputs while providing intermediate resistance to annual weed invasion. AnnualN fertilization maximizes forage yield and minimizes annual weeds in pasture.

Replacing Steam-Flaked Corn And Dry Rolled Corn With Condensed Distillers Solubles In Finishing Diets, Alex H. Titlow, Adam L. Shreck, Stephanie A. Furman Furman, Karla Jenkins, Matt K. Luebbe, Galen E. Erickson

Nebraska Beef Cattle Reports

The interaction between corn processing method and condensed distillers solubles (CDS) was evaluated using either steam-flaked corn (SFC) or dry rolled corn (DRC). As CDS replaced corn at either 15 or 30% of the diet DM, DMI intake decreased quadratically for both SFC and DRC. Within DRC- based diets, ADG increased quadratically with 15% CDS being greatest and F:G improved quadratically with 30% inclusion being best. When SFC was used as the grain source, ADG increased linearly and F:G improved quadratically with increasing levels of CDS. A greater performance response was observed with SFC compared to DRC when feeding increased …

The Effect Of Lameness On Average Daily Gain In Feedlot Steers, Giselle T. Kruse, Richard R. Randle, Douglas E. Hostetler Hostetler, Gary K. Tibbetts, Dicky D. Griffin, Kathryn J. Hanford, Terry Klopfenstein, Galen E. Erickson, Brandon L. Nuttelman, David R. Smith

Nebraska Beef Cattle Reports

The objective of this study was to test the effects of lameness on average daily gain (ADG) of feedlot steers. We evaluated two feedlot health data sets: 1) 14,798 steers from a 14-year period (1993 to 2006) at the Meat Animal Research Center (USDA MARC) near Clay Center, Neb.; and 2) 16,766 steers from an 8-year period (2002 to 2009) at the University of Nebraska Agricultural Research and Development Center (ARDC) near Mead, Neb. The ADG for USDA MARC steers with lameness late in the feeding period (≥ 60 days) was 0.04 lb./day less than steers without lameness. The ADG …

Including Next Enhance® Essential Oils In Finishing Diets On Performance With Or Without Rumensin® And Tylan®, Curtis J. Bittner, Galen E. Erickson, Karla Jenkins Jenkins, Matt K. Luebbe, Troy Wistuba

Nebraska Beef Cattle Reports

Finishing cattle performance was evaluated using NEXT ENHANCE essential oils in finishing diets. Treatments consisted of 1) control (CON), 2) NEXT ENHANCE at 300 mg/day (NE), 3) Rumensin and Tylan at 360 and 90 mg/day, respectively (RT), or 4) NEXT ENHANCE plus Rumensin and Tylan (NERT). No NEXT ENHANCE by Rumensin/Tylan interaction was observed. Steers fed Rumensin/Tylan had decreased F:G and increased live final BW and marbling score. The prevalence of liver abscesses decreased 46% when steers were fed Rumensin/Tylan. Including NEXT ENHANCE in finishing diets did not impact performance or carcass characteristics.

Nebraska Beef Cattle Reports

Two identically designed trials were conducted in separate years at the University of Nebraska Haskell Agricultural Laboratory, Concord, Neb., using 192 crossbred heifers (96/trial). Within a trial, heifers were assigned randomly to 2 groups (3 pens/group): 1) treatment (TRT) animals were administered synthetic hormones via subcutaneous implants (Ralgro and Revalor-H) and fed Melengesterol Acetate (MGA), or 2) control (CON) animals with no synthetic hormone provided.

Gains and feed conversions were 18.8 and 7.5% better, respectively, for TRT, while CON had 16.7% greater choice and prime carcasses. In runoff samples, progesterone was greater for CON. With the exception of androsterone, average …

Anaerobic Digestion Of Finishing Cattle Manure, Andrea K. Watson, Galen E. Erickson, Terry Klopfenstein Klopfenstein, Samodha C. Fernando, Jana L. Harding

Nebraska Beef Cattle Reports

Utilizing manure from cattle fed distillers grains in anaerobic digesters improved methane production and DM degradation of manure compared to manure from cattle fed no distillers grains. Manure from cattle fed in open lot pens had soil contamination which decreased OM content and led to decreased total methane production (L/day), but not when expressed as methane/g OM. If ash buildup is avoided, open lot manure can be used as anaerobic digester feedstock.

Effect Of Development System On Heifer Performance And Primiparous Heifer Grazing Behavior, Adam F. Summers, T. L. Meyer, Jacqueline Musgrave Musgrave, Stetson P. Weber, Rick N. Funston

Nebraska Beef Cattle Reports

The effect of heifer development system on primiparous heifer performance grazing corn residue during late gestation was investigated. Weaned heifers grazing corn residue tended to have reduced final BW after corn residue grazing compared to heifers grazing winter range. However reproductive performance for the two treatments was similar. When grazing corn residue as pregnant heifers during late gestation, heifers developed on corn residue had improved ADG compared to drylot-developed heifers and tended to have increased ADG compared to winter range-developed heifers. Adaptation to corn residue grazing as a developing heifer improves primiparous heifer performance grazing corn residue during late gestation.

Evaluation Of A New Chemistry For Rangeland Grasshopper Control, Jeffrey Bradshaw, Karla Jenkins, Sean Doyle Whipple Whipple, Rick Patrick

Nebraska Beef Cattle Reports

A grasshopper control study was conducted to evaluate the effectiveness of a new class of systemic chemical. The new pesticide Prevathon^® (high and low levels) was compared to Coragen^®, Dimilin^®, and a nontreated check. Grasshoppers were numerically reduced the most by Coragen and Prevathon, though not significant. The highest level of Prevathon did not numerically impact beneficial insects in general. Biomass and forage quality were not significantly impacted by chemical treatment. However, forage biomass was numericallygreatest for the highest level of Prevathon. Prevathon appears to be an acceptable systemic pesticide for grasshopper control with minimal …

In the present article, the case of a crossbred female spayed cat, at the age of 2 years, was presented with hyperelasticity of the skin, alopecia, and an ulcerative wound on the left hind leg. The animal's dorsum was hyperextensible, smooth to the touch, and could be easily torn with minor traumas. To the best of the authors' knowledge, the present report is the first documented feline case of cutaneous asthenia in Turkey.

Current Therapeutic Approaches To Equine Protozoal Myeloencephalitis, L. Dirikolu, Jonathan H. Foreman, Thomas Tobin

Maxwell H. Gluck Equine Research Center Faculty Publications

Equine protozoal myeloencephalitis is the most important infectious neurologic disease of horses in the Western Hemisphere. Equine protozoal myeloencephalitis can interfere with a horse's ability to race, work, and perform; untreated, EPM can be lethal. Antemortem diagnosis of EPM is challenging, requiring careful evaluation of the animal's history, clinical signs, and laboratory data, with rigorous exclusion of other causes.

Therapeutic approaches to EPM are evolving. First-generation therapeutic approaches for EPM were based on the classic anti–Toxoplasma gondii pyrimethamine–sulfonamide combinations; treatment is prolonged and can be associated with a considerable relapse rate, which may be associated with the difficulty in …

Turkish Journal of Veterinary & Animal Sciences

Sixty-five rats (Rattus norvegicus) and 5 mice (Mus musculus) were trapped from 8 outdoor farms and the presence of Shiga toxin-producing Escherichia coli was not detected in any individual. Nevertheless, using the microscopic agglutination test, it was found that 20% (13/65) of rat serum samples were positive for anti-Leptospira antibodies, and DNA of pathogenic leptospires was detected in 3.07% (2/65) of the rat kidneys by real-time polymerase chain reaction. The most common infecting serovar was Castellonis (7.69%), followed by Canicola (6.15%) and Mangus (6.15%). According to these results, rats from outdoor farms may be considered a reservoir host for Leptospira …

Development Of A Subunit Vaccine Against Bovine Diarrhea Caused By K99 Enterotoxigenic Escherichia Coli And Bovine Viral Diarrhea Virus, Emad Hashish

Electronic Theses and Dissertations

Bovine diarrhea is economically one of the most important problems in cattle industry. Enterotoxigenic Escherichia coli (ETEC), particularly strains expressing K99 (F5) fimbriae and heat-stable type I (STa) enterotoxin is the predominant bacterial cause of diarrhea in calves; whereas bovine viral diarrhea virus (BVDV) causes diarrhea and other illness to cattle at all ages. A vaccine that prevents against both K99 fimbrial ETEC and BVDV could benefit greatly to cattle producers worldwide. We hypothesized that a novel multivalent vaccine composed of K99, STa and BVDV E2 antigens could induce immunity for broad protection against bovine diarrhea. In this study we …

Cytotoxicity Of Nickel Ions For Human Osteoblasts In The Context Of Orthodontic Treatment In Humans And Animals, Marcin Mikulewicz, Katarzyna Chojnacka, Iwona Kochanowska, Agnieszka Dziewicka, Maciej Janeczek, Jerzy Cieplik, Aleksander Chrószcz

Turkish Journal of Veterinary & Animal Sciences

In the present work, the biocompatibility of orthodontic devices was tested by the propagation of human osteoblasts. A different methodological approach was applied. Since the materials used in human and veterinary orthodontics (not in implantology) had been tested, osteoblasts were not implanted on the surface of the biomaterial, but have been cultured in the medium containing the products of corrosion. In the present work, osteoblasts were propagated in the medium spiked with Ni(II) salt versus the control. Osteoblast cells (live, dead, and total) were counted under light microscope. The statistical significance of the differences between the experimental and control groups …
