Acidosis is one of the more important maladies afflicting cattle fed significant amounts of grain and has enormous economic impact for feedlots, dairies, and producers of seed stock. The highest incidence of acidosis occurs when animals are being transitioned from high-roughage diets to diets containing high levels of concentrates. When grain-based diets are consumed in excess, consumed too quickly, or fed without proper adaptation, digestive end products (organic acids) can accumulate within the rumen, resulting in acidosis. Lactic acid is one of the key organic compounds that accumulates under these conditions. Coupled with the animal's limited ability to metabolize lactate, …
Effects Of Crude Glycerin On Ruminal Metabolism And Diet Digestibility Of Flaked-Corn Finishing Diets, G.L. Parsons, James S. Drouillard

Expansion of the biodiesel industry has increased supplies of crude glycerin available for livestock feeding. Catalyzed reactions between methanol and triglycerides from vegetable oils, such as soybean oil, yield biodiesel and a coproduct, crude glycerin. Approximately 10% of the weight of soybean oil used to produce biodiesel becomes glycerin. Limited work has been conducted to understand metabolism of glycerin in ruminant livestock. In previous studies at Kansas State University, feeding crude glycerin at 8% or less of the diet improved cattle performance. Subsequent laboratory experiments indicated that low levels of glycerin may improve ruminal fermentation. This study was conducted to …
Increased Concentrations Of Bovine Intestinal Mucus Encourage Growth Of Escherichia Coli O157:H7, J. Heidenreich, C. Aperce, James S. Drouillard

Cattle have been implicated as carriers of the human pathogen Escherichia coli O157:H7. Contamination of the beef supply by E. coli O157 can occur during harvest and processing, causing costly recalls or human illness. Many interventions have been applied in attempts to prevent contamination of carcasses in processing plants, such as development of HACCP procedures, carcass washes, and steam pasteurization, but contaminations still occur. Mechanisms that allow E. coli O157:H7 to thrive in cattle at sporadic times and in such large numbers are poorly understood. Understanding factors that stimulate E. coli O157 growth in cattle will aid in identifying effective …

Bovine respiratory disease continues to be the most costly disease affecting productivity and profitability in the stocker segment. Long-acting injectable antimicrobials are presently used to reduce the incidence and severity of bovine respiratory disease. However, future use of antimicrobial treatment may be significantly curtailed in light of an increasing negative perception of antibiotic usage in food animals by consumers and governmental agencies. Consequently, preconditioning and enhanced nutrition programs that may include nutraceuticals could become more prevalent. MorindaMax (Morinda International, Provo, UT) is a natural product manufactured from the Morinda citrifolia fruit (i.e., Noni). Published literature suggests this plant extract has …
Packaging Systems And Storage Times Serve As Post-Lethality Treatments For Listeria Monocytogenes On Kippered Beef Steaks, A. Lobaton-Sulabo, K. Uppal, Kelly J.K. Getty, Elizabeth A.E. Boyle, N. Harper, B. Barry, James J. Higgins

Following several outbreaks involving Listeria monocytogenes in ready-to-eat meat and poultry products, the United States Department of Agriculture Food Safety and Inspection Service required that processors of these products implement post-processing intervention strategies for controlling L. monocytogenes. The USDA defines a postlethality treatment as a process that reduces L. monocytogenes by at least 1 log. Research has shown that packaging can generate a 1 log L. monocytogenes reduction following 1 or more weeks of storage at room temperature. The objective of our study was to determine the effect of packaging system and storage time on reducing L. monocytogenes in shelf-stable …
