Steak Location Within The Semitendinosus Muscle Impacts Metmyoglobin Accumulation On Steaks During Retail Display, K. J. Phelps, T. G. O'Quinn, T. A. Houser, J. M. Gonzalez

Kansas Agricultural Experiment Station Research Reports

Beef color is a major attribute consumers utilize to make purchasing decisions. It is estimated poor color shelf-life of beef steaks costs the meat industry more than $1 billion annually. Shelf-life color is influenced by a balance of two biochemical processes within steaks: metmyoglobin reducing ability and oxygen consumption. Steaks that exhibit a greater metmyoglobin reducing and a reduced oxygen consumption are typically characterized as more color stable. Characteristics of the muscle fiber or muscle cell are what determine the properties of a steak. Commonly, muscles with more oxidative fibers have an elevated oxygen consumption and reduced metmyoglobin reducing ability ...

Coarse Marbled Beef Is Juicier And More Flavorful Than Fine Or Medium Marbled Beef, K. R. Vierck, J. M. Gonzalez, T. A. Houser, E. A. Boyle, T. G. O'Quinn

Kansas Agricultural Experiment Station Research Reports

Beef palatability and eating experience is driven primarily by U.S. Department of Agriculture quality grade and marbling levels. Beef USDA quality grade consists of both marbling levels and maturity. Conventionally, marbling texture has not been a consideration of quality grades. Currently, only one study has assessed the effects of marbling texture on beef palatability. Despite this, preferences for fine or medium marbling exist with both packers and retailers, as approximately 75% of branded beef programs under the supervision of USDA-AMS require fine or medium textured marbling, which equates to losses of premiums for packers and producers (USDA, 2016). The ...

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 ...

Evaluation Of Trace Mineral Sources On Newly Arrived Stocker Cattle, C. S. Weibert, W. R. Hollenbeck, S. B. Laudert, J. D. Kubick, Dale Blasi

Kansas Agricultural Experiment Station Research Reports

Light weight stocker calves experience variable degrees of physiological and psychological stressors as they are assembled from various marketing points and transported to their destination. Susceptibility to disease in young, long hauled calves is greatly enhanced and the consequence of sickness is a major cause for poor production outcomes. Enhanced nutritional trace mineral programs that contain zinc, copper, and manganese from organic or hydroxy sources may be more efficacious as a means of minimizing disease or realizing improved performance than the sulfate form of these respective trace minerals.

Route Of Mannheimia Haemolytica And Pasteurella Multocida Vaccine Administration Does Not Affect Health Or Performance Of Receiving Heifers, T. Spore, M. E. Corrigan, T. R. Parks, C. S. Weibert, M. L. Detray, W. R. Hollenbeck, R. N. Wahl, Dale Blasi

Kansas Agricultural Experiment Station Research Reports

Light weight stocker calves often experience health problems shortly after arrival to feeding facilities. Preventative health programs are routinely administered to calves upon arrival to reduce the incidence of Bovine Respiratory Disease. The major route of vaccine administration in cattle is via injection through either intramuscular or subcutaneous routes. Several products have been introduced that utilize the intranasal route of vaccine administration. There are several reasons why intranasal vaccine administration may be more beneficial: 1) Intranasal vaccine administration alleviates concerns that injections pose for Beef Quality Assurance programs. 2) Intranasal vaccine administration may be less stressful on the animal. 3 ...

Kansas Agricultural Experiment Station Research Reports

Optaflexx is a beta-adrenergic agonist, and is fed to cattle during the final 28 to 42 days on feed to improve growth rate and feed efficiency. Beta-adrenergic agonists are repartitioning agents that stimulate muscle deposition at the expense of fat deposition. Zinc is a trace mineral element that functions as an important component of many enzyme systems, including those associated with nucleic acid synthesis and metabolism of proteins and carbohydrates, thus making it an essential nutrient for growth. The purpose of this study was to evaluate growth, carcass characteristics, and plasma urea nitrogen concentrations in finishing heifers supplemented with Optaflexx ...


Tenderness, Juiciness, And Flavor Contribute To The Overall Consumer Beef Eating Experience, L. N. Drey, T. G. O'Quinn Jan 2017

Tenderness, Juiciness, And Flavor Contribute To The Overall Consumer Beef Eating Experience, L. N. Drey, T. G. O'Quinn

Kansas Agricultural Experiment Station Research Reports

Overall beef palatability can be attributed to three primary traits, tenderness, juiciness, and flavor, as well as the interaction among these traits (Smith and Carpenter, 1974). Multiple authors have worked to identify which of these palatability traits contributes the most to overall eating satisfaction and have historically identified tenderness as the most important palatability trait (Savell et al., 1987; Miller et al., 1995a; Savell et al., 1999; Egan et al., 2001). Overall eating quality of beef steaks may excel at one or even two of these traits, yet fail to meet consumer eating expectations due to the unsatisfactory level of ...

Effects Of Growing-Season Prescribed Burning On Vigor Of Sericea Lespedeza In The Kansas Flint Hills: Ii. Plant-Species Composition, J. A. Alexander, W. H. Fick, J. Lemmon, G. A. Gatson, G. W. Preedy, K C. Olson

Kansas Agricultural Experiment Station Research Reports

Fire has, for centuries, been a key force for sustainability of native ecosystems in the Kansas Flint Hills. Prior to the arrival of European settlers, prescribed and wild fires occurred at less than 3-year intervals in the tallgrass prairie region. As a result, native tallgrass plant communities adapted to fire at regular intervals and plant-species composition became stable on a geologic time scale.
Currently, prescribed fire is used in the Kansas Flint Hills as a treatment for control of woody-stemmed invasive species such as eastern red cedar, honey locust, and roughleaf dogwood. These fires are generally applied in March and ...

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 ...

Kansas Agricultural Experiment Station Research Reports

Water is an essential part of livestock and human diets and is often thought of as an inexpensive, readily available renewable natural resource. However, the amount of competition between humans, wildlife, feed production, and livestock for high-quality water is increasing, not only from the effects of drought but from the pressure of a growing global population (Nardone et al., 2010). With limited resources available for production agriculture, there is a need to identify and select for efficient animals that can produce more product with fewer inputs. Although some work has been done in dairy cattle, very little data is available ...
