Dried Corn Germ In Natural Finishing Programs Reduces Incidence Of Liver Abscess, J.O. Wallace, James S. Drouillard, Christopher D. Reinhardt Jan 2009

Dried Corn Germ In Natural Finishing Programs Reduces Incidence Of Liver Abscess, J.O. Wallace, James S. Drouillard, Christopher D. Reinhardt

Kansas Agricultural Experiment Station Research Reports

Changes in consumer preference for beef produced without growth promotants, ionophores, or antibiotics and consumers' willingness to pay price premiums for such products have led some producers to begin raising beef under "natural" feeding regimens. Some natural programs prohibit use of injectable antibiotics, feed additive drugs, or growth promoting implants throughout the life of the animal. This creates challenges for maintaining efficient growth and preventing disease or metabolic disorders. A key problem facing producers who feed cattle under a natural regimen, without use of antibiotics such as tylosin and ionophores, is ruminal acidosis, which is commonly linked with liver abscesses. …

Kansas Agricultural Experiment Station Research Reports

An experiment was conducted to determine the digestibility of amino acids (AA) and energy in high-protein sorghum dried distillers grain with solubles (DDGS). Six growing barrows (initially 50 lb) surgically fitted with T-cannulas were randomly assigned to 1 of 2 dietary treatments in a 2-period crossover design. The treatments were a diet with the high-protein sorghum DDGS (50% of the diet) as the only protein source and an N-free diet for determining basal endogenous AA loss. Both diets contained 0.25% chromic oxide as an indigestible marker. Fecal and ileal digesta samples were collected during each period for energy and AA …

Needle-Free Injection Enhancement Of Beef Improves Tenderness But Slightly Increases Microbial Translocation, A. Sutterfield, B.A. Crow, J.P. Grobbel, Randall K. Phebus, Michael E. Dikeman, Larry C. Hollis Jan 2009

Needle-Free Injection Enhancement Of Beef Improves Tenderness But Slightly Increases Microbial Translocation, A. Sutterfield, B.A. Crow, J.P. Grobbel, Randall K. Phebus, Michael E. Dikeman, Larry C. Hollis

Kansas Agricultural Experiment Station Research Reports

Blade tenderization has been used for decades to increase tenderness in beef cuts that are highly variable in tenderness or predicted to be "tough." Injection enhancement also is commonly used in industry to increase tenderness, juiciness, and flavor of some beef muscles. These processes have the potential to translocate microbial organisms on the exterior to interior portions of whole muscles. One research study reported that 3 to 4% of surface bacteria are transferred into the interior of muscles but only penetrate an average of ¼ inch deep into the surface. Even though the frequency of subprimal surfaces being contaminated with …

Thermal Process With Additional Drying Provides Proper Lethality For Controlling Pathogens During Jerky Production, Kelly J.K. Getty, N.M. Harper, Elizabeth A.E. Boyle Jan 2009

Thermal Process With Additional Drying Provides Proper Lethality For Controlling Pathogens During Jerky Production, Kelly J.K. Getty, N.M. Harper, Elizabeth A.E. Boyle

Kansas Agricultural Experiment Station Research Reports

The New Mexico Department of Health linked salmonellosis to beef jerky in 2003 after 26 individuals became ill; this prompted a recall of nearly 21,600 lb of product. Following this incident, the USDA's Food Safety and Inspection Service instituted the Compliance Guideline for Meat and Poultry Jerky Produced by Small and Very Small Plants in 2004 and updated this document in 2007 with the Quick Guide on Jerky Processing. The Quick Guide states that water activity for jerky products should be ≤ 0.85 for safety and a moisture-to-protein ratio (MPR) must be ≤ 0.75:1 for product to be labeled as …

Influences Of Heat Stress On Serological Response And Performance Of Dairy Calves (2009), Larry C. Hollis, Michael J. Brouk

Kansas Agricultural Experiment Station Research Reports

Objectives of this study were to investigate the possible effects of heat stress on calf growth and the development of active immunity. Eighteen heifer calves born between July 21 and August 24, 2008, were housed in individual hutches, and half of the calves were provided supplemental shade from birth to 8 weeks of age. During this time, milk replacer intake, dry feed intake, and fecal scores were recorded daily. Calf weight and hip and shoulder heights were measured and recorded weekly. The bovine viral diarrhea portion of the vaccine given at 5 weeks of age was used as an indicator …

Effect Of Acidulant Addition On Yogurt Fermentation (2009), Karen A. Schmidt Jan 2009

Effect Of Acidulant Addition On Yogurt Fermentation (2009), Karen A. Schmidt

Kansas Agricultural Experiment Station Research Reports

Yogurt was manufactured by pre-acidifying the yogurt mix with citric acid, lactic acid, or concentrated lemon juice either before or after pasteurization to a target pH of 6.2, and then the traditional manufacturing process was continued. Adding citric acid or lemon juice to the yogurt mix after pasteurization resulted in a 13% reduction in fermentation time compared with the control. This reduction in fermentation time may result in greater efficiency for yogurt manufacturers, allowing for a more sustainable manufacturing process.; Dairy Day, 2009, Kansas State University, Manhattan, KS, 2009; Dairy Research, 2009 is known as Dairy Day, 2009

Differences Among High, Medium, And Low Profitdairy Operations: An Analysis Of 2004-2008 Kansasfarm Management Association Dairy Enterprises (2009), K.M. Schulte, Kevin C. Dhuyvetter

Kansas Agricultural Experiment Station Research Reports

The financial bottom line, or net income, is a key factor in determining how successful a dairy has been historically as well as an indicator of the financial ease or struggles the dairy might have in the future. What causes net income to vary from one operation to another is a key question for dairy farmers. For example, does milk price received, feed cost, total cost, or milk production have the greatest impact on net return variability? In this study, we evaluated Kansas Farm Management Dairy Enterprise data from the past 5 years to determine correlation of revenue, production, and …

Kansas Agricultural Experiment Station Research Reports

There is increasing consumer demand for leaner and healthier pork products. Improvements in genetics, new technologies, and increased understanding of nutrition have become instrumental in helping producers meet this demand. Continued research also has led to the development of products that can be included in swine diets as carcass modifiers. A dietary carcass modifier is broadly defined as any component of the diet that alters the resulting carcass composition of pigs. Generally, the mechanism of action of carcass modifiers is aimed at increasing protein and muscle deposition while reducing fat deposition. These products vary in the mechanisms by which they …
