Kansas Agricultural Experiment Station Research Reports

Ambulatory electrocardiogram monitoring, in the form of Holter monitoring, has been used in human and veterinary medicine for decades as an aid in the diagnosis and determination of appropriate therapy of heart rhythm disturbances. Within veterinary medicine, Holter monitors have been primarily used in companion animal species, yet little attention has been given to food animal species. Moreover, the heart rhythm in clinically normal cattle fed high concentrate diets and housed outdoors in confined drylot facilities has not been previously reported. In order to properly identify pathologic arrhythmias in cattle, the normal rhythm and arrhythmia prevalence in healthy cattle should ...

Differences In Efficacy Between Gamithromycin, Tilmicosin, And Tulathromycin As Metaphylactic Treatments In High Risk Calves For Bovine Respiratory Disease, T. Miller, M. E. Hubbert, E. F. Schwandt, D. U. Thomson, C. D. Reinhardt Jan 2017

Differences In Efficacy Between Gamithromycin, Tilmicosin, And Tulathromycin As Metaphylactic Treatments In High Risk Calves For Bovine Respiratory Disease, T. Miller, M. E. Hubbert, E. F. Schwandt, D. U. Thomson, C. D. Reinhardt

Kansas Agricultural Experiment Station Research Reports

The cost of Bovine Respiratory Disease to the beef industry due to death, poorer conversions, and therapy is estimated to cost more than $3 billion per year. Identifying and mitigating Bovine Respiratory Disease in cattle can be difficult due to the increased susceptibility for Bovine Respiratory Disease in high risk cattle. One management option to minimize an outbreak of respiratory disease is the use of metaphylaxis, the mass treatment of a group of calves to reduce the incidence and adverse effects of respiratory disease on high risk animals. Criteria used to determine the necessity of metaphylactic treatment against Bovine Respiratory ...


Prevalence Of Horns In A Pen Does Not Affect Incidence Of Carcass Bruising In Feedlot Cattle, M. E. Youngers, E. F. Schwandt, D. U. Thomson, J. C. Simroth, S. J. Bartle, M Siemens, C. D. Reinhardt Jan 2017

Prevalence Of Horns In A Pen Does Not Affect Incidence Of Carcass Bruising In Feedlot Cattle, M. E. Youngers, E. F. Schwandt, D. U. Thomson, J. C. Simroth, S. J. Bartle, M Siemens, C. D. Reinhardt

Kansas Agricultural Experiment Station Research Reports

Disbudding and dehorning are two common practices done to remove horns from cattle to prevent injury to handlers and other cattle and to reduce bruising of carcasses. Bruised carcasses result in substantial reduction in profit due to trim loss, increased sanitation risk, and loss in time on the rail during processing. Previous research has indicated that cattle with horns increased hide damage of cohorts and caused injury to handlers. Cattle with horns cause circular shaped bruises that lead to trim loss due to bruising. Cattle with tipped horns do not have a lower bruising rate than cattle with intact horns ...


Liver Abscess Severity At Slaughter Does Not Affect Meat Tenderness And Sensory Attributes In Commercially Finished Beef Cattle Fed Without Tylosin Phosphate, E. J. Mccoy, T. G. O'Quinn, E. F. Schwandt, C. D. Reinhardt, D. U. Thomson Jan 2017

Liver Abscess Severity At Slaughter Does Not Affect Meat Tenderness And Sensory Attributes In Commercially Finished Beef Cattle Fed Without Tylosin Phosphate, E. J. Mccoy, T. G. O'Quinn, E. F. Schwandt, C. D. Reinhardt, D. U. Thomson

Kansas Agricultural Experiment Station Research Reports

Liver abscesses are a significant problem in the United States’ cattle feeding industry, costing the industry an estimated $15.9 million annually in liver condemnation, trim losses, and reduced carcass weights and quality grades. Recent reported incidence rates of liver abscesses at slaughter range from 10 to 20%. Liver abscess incidence may be influenced by a number of factors including: breed, gender, diet, days on feed, cattle type, season, and geographical location. Liver abscesses typically occur secondary to rumen insults caused by acidosis or rumenitis. It has been proposed that pathogens associated with liver abscess formation enter the blood stream ...
