Kansas Agricultural Experiment Station Research Reports

Optimizing growth rate is an important contributor to overall profitability for stocker cattle grazing native Flint Hills pasture. Disease challenges from pinkeye and foot rot have traditionally been problems that compromise health and productivity of stocker cattle in this grazing region. Use of medicinal feed additives as a part of a supplementation program may prevent health problems and improve overall productivity during a spring/summer grazing season.


Feed-Based Metaphylaxis Programs Did Not Affect Health Or Performance Of High-Risk Calves Mass Medicated With Draxxin On Arrival, M.P. Epp, R. Derstein, Dale A. Blasi 2010 Kansas State University Libraries

Feed-Based Metaphylaxis Programs Did Not Affect Health Or Performance Of High-Risk Calves Mass Medicated With Draxxin On Arrival, M.P. Epp, R. Derstein, Dale A. Blasi

Kansas Agricultural Experiment Station Research Reports

Bovine respiratory disease continues to be the most costly disease affecting productivity and profitability in the stocker segment. Despite their high cost, longer-acting, injectable therapeutic antimicrobials such as Draxxin (Tulathromycin; Pfizer Animal Health, New York, NY) can extend the window of treatment duration, thereby reducing the incidence and severity of bovine respiratory disease. Use of feed-based metaphylaxis programs, such as therapeutic administration of multiple 5-day pulses of Aureomycin (αrma, Inc., Bridgewater, NJ), in conjunction with an injectable metaphylaxis program may be a cost-effective way to improve bovine respiratory disease therapy without having to physically handle and stress cattle.


Round Bale Alfalfa Processing Method Affects Heifer Growth But Does Not Influence Wastage Or Eating Preference, S.Q. Jones, T.T. Marston, T.J. Kraus, Joel M. DeRouchey, Justin W. Waggoner, Ryan M. Breiner 2010 Kansas State University Libraries

Round Bale Alfalfa Processing Method Affects Heifer Growth But Does Not Influence Wastage Or Eating Preference, S.Q. Jones, T.T. Marston, T.J. Kraus, Joel M. Derouchey, Justin W. Waggoner, Ryan M. Breiner

Kansas Agricultural Experiment Station Research Reports

Many factors affect forage quality, including moisture level at baling, compaction, bulk density, and maturity at harvest. Losses of dry matter and nutrient value occur during field curing. Hay baled at or above 18% moisture should have less nutrient loss in the field. However, hay baled at these moisture levels has the potential to heat during storage, causing dry matter loss and nutrient degradation. Also, as particle length of forage decreases, packing ability of forage and bulk density of bales increase. Although particle length is reduced by grinding baled forage, this can result in nutrient losses. Also, when cattle are ...

Botanical Composition Of Diets Grazed By Beef Cows In The Kansas Flint Hills During Winter, G.J. Eckerle, K. C. Olson, Walter H. Fick, L.A. Pacheco, John R. Jaeger

Kansas Agricultural Experiment Station Research Reports

Analysis of microscopic plant fragments recovered from the gut of wild herbivores (i.e., microhistological analysis) has been used to estimate diet composition, but there is debate as to whether microhistological analysis of fecal samples is an appropriate method for characterizing diets of grazing beef cattle. Therefore, our goal was to determine whether this approach could effectively quantify the botanical composition of diets grazed by mature beef cows in the Kansas Flint Hills during winter.


Effects Of Smartlic Hi-Pro 40 Block Supplements On Ruminal Microbes In Cattle Fed Low-Quality Forages, K.D. Derstein, James S. Drouillard 2010 Kansas State University Libraries

Effects Of Smartlic Hi-Pro 40 Block Supplements On Ruminal Microbes In Cattle Fed Low-Quality Forages, K.D. Derstein, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Dormant pastures and native grass hays often are deficient in protein and other nutrients needed to support optimum performance of beef cattle. These nutrients are essential for maintaining viable populations of symbiotic rumen microorganisms that digest the fiber in forages. When nutrient deficiencies occur, microbial populations in the rumen decrease, thereby limiting digestion of low-quality forages. This study was conducted to evaluate changes in rumen microbial populations and digestive activity when cattle consuming low-protein native grass hay are given access to high-protein, free-choice block supplements.

Kansas Agricultural Experiment Station Research Reports

Ractopamine hydrochloride (Elanco, Greenfield, IN) and Zilmax (zilpaterol hydrochloride; Intervet/Schering-Plough, Millsboro, DE) are β-adrenergic agonists approved in the United States and several other countries to increase growth rate, improve efficiency of feed utilization, and increase carcass meat yield. Zilmax has been shown to improve feed efficiency by 26% and increase hot carcass weight, longissimus muscle area, and meat yield. However, a few studies have shown that Zilmax significantly increased Warner-Bratzler shear force values (decreased tenderness). The objectives of our research were to determine the effects of supplementing feedlot diets of steers and heifers with Zilmax for 0, 20, 30 ...


Effect Of Nitrogen Supplementation And Zilpaterol-Hcl On Urea Recycling In Steers Consuming Corn-Based Diets, D.W. Brake, M.L. Jones, Evan C. Titgemeyer 2010 Kansas State University Libraries

Effect Of Nitrogen Supplementation And Zilpaterol-Hcl On Urea Recycling In Steers Consuming Corn-Based Diets, D.W. Brake, M.L. Jones, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Cattle have the innate ability to recycle nitrogen absorbed post-ruminally back to the rumen as endogenously synthesized urea. Urea returning to the rumen provides an additional opportunity for ruminal microbes to benefit from nitrogen absorbed postruminally. Urea recycling may provide a significant benefit to cattle when protein requirements of ruminal microbes are high or when large amounts of the dietary protein escape ruminal degradation.


Increased Concentrations Of Bovine Intestinal Mucus Encourage Growth Of Escherichia Coli O157:H7, J. Heidenreich, C. Aperce, James S. Drouillard 2010 Kansas State University Libraries

Increased Concentrations Of Bovine Intestinal Mucus Encourage Growth Of Escherichia Coli O157:H7, J. Heidenreich, C. Aperce, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

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 ...

Effects Of Supplemental Protein And Energy On Digestion And Urea Kinetics In Beef Cattle, E.A. Bailey, D.W. Brake, David E. Anderson, M.L. Jones, Evan C. Titgemeyer, K. C. Olson

Kansas Agricultural Experiment Station Research Reports

Previous research at Kansas State University has shown that providing supplemental energy when protein is deficient will cause a decrease in digestion of low-quality forage. Our project examined the effects of supplemental glucose on low-quality forage intake and digestion. Urea recycling is a mechanism by which cattle preserve nitrogen when faced with a deficiency. Young, growing cattle receiving sufficient protein recycle large amounts of nitrogen to the rumen. Our goal was to explore the effects of providing supplemental energy and protein to cattle that are on the downward side of their growth curve. Specifically, we measured intake, digestion, and urea ...

Kansas Agricultural Experiment Station Research Reports

Expansion of the renewable fuels industries has increased availability of by-products that are well suited for use as cattle feed. Glycerin is among the principal by-products of biodiesel production, comprising approximately 10% (by weight) of the soybean oil that is used to manufacture soy-based diesel fuel. Our previous research evaluated effects of including between 0% and 16% glycerin in flaked-corn finishing diets and revealed that optimal growth performance was achieved with 2% glycerin addition. Our laboratory experiments have suggested that even lower levels of glycerin may be effective at stimulating digestion. Therefore, the objective of this study was to evaluate ...

Needle-Free Injection Enhancement Of Beef Strip Loins With Phosphate And Salt Has Potential To Improve Yield, Tenderness, And Juiciness But Harm Texture And Flavor, B.A. Crow, Michael E. Dikeman, A.N. Ray, Terry A. Houser, J.P. Grobbel, Larry C. Hollis, Randall K. Phebus

Kansas Agricultural Experiment Station Research Reports

Meat tenderness is the most important palatability attribute affecting consumers' overall eating experience. Injection enhancement and blade tenderization have long been used to improve this important trait. Injection enhancement has been shown to improve tenderness, juiciness, color stability, and cooking yield, but not all solutions have been adequately evaluated. Thus, there is a need to conduct research on the effectiveness of common enhancement solutions. We published results from an extensive study comparing a solution of phosphate, salt, and rosemary with a solution of calcium lactate and rosemary injected by using traditional needle injection. There were no differences in Warner-Bratzler shear ...

Packaging Systems And Storage Times Serve As Post-Lethality Treatments For Listeria Monocytogenes On Whole Muscle Beef Jerky, A. Lobaton-Sulabo, T. Axman, Kelly J.K. Getty, Elizabeth A.E. Boyle, N. Harper, K. Uppal, B. Barry, James J. Higgins

Kansas Agricultural Experiment Station Research Reports

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 on shelf-stable ...

Effects Of Wet Corn Gluten Feed And Dietary Particle Size On Ruminal Fermentation And Milk Production, M.L. Sullivan, Barry J. Bradford

Kansas Agricultural Experiment Station Research Reports

Wet corn gluten feed (WCGF) was included in 4 diets at 0, 11, 23, and 34% of diet dry matter. Alfalfa hay was used to maintain at least 10% of particles ≥0.71 inches in length (the top screen of the Penn State Particle Separator) in all diets. Ruminal probes were placed in the rumens of 7 ruminally cannulated lactating Holstein dairy cows to measure ruminal pH. As WCGF increased in the diet, dry matter intake and milk production increased quadratically with 23% WCGF supporting the highest feed intake and milk yield. Ruminal pH and milk fat content were similar ...
