Kansas Agricultural Experiment Station Research Reports

Antimicrobial metaphylaxis is an important tool used for the prevention of Bovine Respiratory Disease Complex; a disease with a large economic impact that typically affects newly-weaned beef calves that are marketed and transported a distance from their origin.

There are questions involving the potential benefit of Zelnate, a novel non-antibiotic technology designed to activate an animal’s natural immunity to fight Bovine Respiratory Disease Complex, being used either solely or in combination with metaphylaxis at the time of initial processing of high risk calves. More knowledge is also needed regarding the possible effects of repeated use of Zelnate when subsequent ...


Antioxidant Feeding Does Not Impact Incidence Or Severity Of Liver Abscesses, H. C. Muller, C. L. Van Bibber-Krueger, J. S. Drouillard Jan 2017

Antioxidant Feeding Does Not Impact Incidence Or Severity Of Liver Abscesses, H. C. Muller, C. L. Van Bibber-Krueger, J. S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Liver abscesses are a large source of economic loss in feedlot cattle. Not only do liver abscesses lead to a decrease in feedlot performance, but these livers are condemned in the abattoir and can also lead to a further decrease in carcass value due to trim loss. Tylosin phosphate is a metaphylactic macrolide drug that effectively decreases the occurrence of liver abscesses. The drug is approved by the Food and Drug Administration for over-the-counter use. However, in January 2017 the FDA will require a veterinary feed directive for medically important antibiotics (antibiotics that are used in human health) used in ...

Kansas Agricultural Experiment Station Research Reports

Defining the appropriate dimensions and type of feeding facilities for feedlot cattle fed in outdoor pens is important because the characteristics of these facilities have a significant impact on the performance, welfare, and health of cattle housed in those facilities, as well as a considerable impact on the final cost of the project. Although multiple sources can be found in the literature that provide recommendations with regard to design of facilities to be used in outdoor feeding facilities for feedlot cattle, there are no published data that describe the dimensions and type of feeding facilities currently used by the feedlot ...


Feeding Nucleotides With Corn Germ Meal Or Dried Corn Distillers Grains Does Not Promote Growth Performance Of Receiving And Growing Calves, M. L. Detray, S. P. Montgomery, E. Titgemeyer, A. E. Wertz-Lutz, Christopher Vahl, A. T. Schilling, W. R. Hollenbeck, Dale Blasi Jan 2017

Feeding Nucleotides With Corn Germ Meal Or Dried Corn Distillers Grains Does Not Promote Growth Performance Of Receiving And Growing Calves, M. L. Detray, S. P. Montgomery, E. Titgemeyer, A. E. Wertz-Lutz, Christopher Vahl, A. T. Schilling, W. R. Hollenbeck, Dale Blasi

Kansas Agricultural Experiment Station Research Reports

Corn germ meal is often used in swine and poultry diets, but very little information exists on the effects on beef cattle and on newly arrived stressed cattle. When formulating receiving and growing diets, calf health and stress are important factors to consider. Including nucleotides, an immune-boosting feed additive may aid in gastrointestinal health of an animal and furthermore improve growth performance. The objective of these experiments was to determine: 1) the effects of corn germ meal in comparison to dried corn distillers grains on growth performance and 2) the effects of nucleotides on growth performance, by receiving and growing ...


Particle Size Of Dry-Rolled Corn Affects Starch Digestibility But Not Feedlot Performance, E. F. Schwandt, J. Wagner, T. Engle, S. J. Bartle, D. U. Thomson, C. D. Reinhardt Jan 2017

Particle Size Of Dry-Rolled Corn Affects Starch Digestibility But Not Feedlot Performance, E. F. Schwandt, J. Wagner, T. Engle, S. J. Bartle, D. U. Thomson, C. D. Reinhardt

Kansas Agricultural Experiment Station Research Reports

Dry-rolling corn is a common practice in feedlots located in the Midwestern and Northern Plains regions of the United States. Optimizing total digestive tract starch utilization in diets containing dry-rolled corn is essential for maximizing efficiency. However, recommendations often suggest that grain be coarsely cracked to avoid producing an excessive amount of fine material that could potentially increase the rate of fermentation, reduce rumen pH, and cause digestive disturbances.

Wet distillers byproducts may be effectively used as a protein and energy source for feedlot finishing cattle and can replace a portion of the dry-rolled corn in the diet. The average ...


Flake Density, Roll Diameter, And Flake Moisture All Influence Starch Availability Of Steam-Flaked Corn, E. F. Schwandt, M. E. Hubbert, D. U. Thomson, Christopher Vahl, S. J. Bartle, C. D. Reinhardt Jan 2017

Flake Density, Roll Diameter, And Flake Moisture All Influence Starch Availability Of Steam-Flaked Corn, E. F. Schwandt, M. E. Hubbert, D. U. Thomson, Christopher Vahl, S. J. Bartle, C. D. Reinhardt

Kansas Agricultural Experiment Station Research Reports

Steam-flaked corn is commonly fed in feedlot finishing diets because steam-flaking improves starch availability and nutrient utilization, thus improving the overall feeding value of corn. In most operations which utilize steam-flaked corn, grain is processed to a pre-determined flake density by setting the rolls to a specific separation distance and using tension to hold rolls together. Flaked grain is most often produced to a bulk density between 24 and 32 lb/bu, with a common recommendation of 27 lb/bu for corn; however, flake density among steam-flakers within a single mill and among feedlots can vary greatly. Flaking to a ...

Lactic acid spray washes are widely used as an antimicrobial intervention in the beef industry. Sprays are typically applied to the exterior of carcasses and subprimal cuts to reduce or eliminate potential pathogenic bacteria. While the efficacy of these washes has been proven, other questions remain about their effect on color attributes of meat when applied to subprimal cuts. The objective of this study was to determine the effect of a lactic acid subprimal wash on the color stability of beef chuck rolls.

Effects Of Various Grazing Systems On Grazing And Subsequent Finishing Performance, L. W. Lomas, J. L. Moyer

Kansas Agricultural Experiment Station Research Reports

A total of 280 mixed black yearling steers were used to compare grazing and subsequent finishing performance from pastures with ‘MaxQ’ tall fescue, a wheat-bermudagrass double-crop system, or a wheat-crabgrass double-crop system in 2010, 2011, 2012, 2013, 2014, 2015, and 2016. Daily gains of steers that grazed MaxQ fescue, wheatbermudagrass, or wheat-crabgrass were similar (P > 0.05) in 2010 and 2016. Daily gains of steers that grazed wheat-bermudagrass or wheat-crabgrass were greater (P > 0.05) than those that grazed MaxQ fescue in 2011 and 2012. Daily gains of steers that grazed wheat-crabgrass were greater (P > 0.05) than those that ...

Kansas Agricultural Experiment Station Research Reports

Molecular diagnosis of porcine reproductive and respiratory syndrome virus (PRRS) and porcine circo virus (PCV) are challenging due to high genetic diversity in the viral genomes. Differentiating PRRS vaccine strains is even more challenging and is currently done by DNA sequencing, which is expensive and time-consuming. A multiplexed system (Luminex) allowing multiple detection targets in the same reaction is available. However, this system is not fully developed for common swine pathogens. Therefore, an assay was built to detect the majority of field PRRS strains by using different pairs of primers, and at the same time, to provide differentiation of the ...
