Horn Fly Control And Growth Implants Are Effective Strategies For Heifers Grazing Flint Hills Pasture, S. S. Trehal, J. L. Talley, K. D. Sherrill, T. Spore, R. N. Wahl, W. R. Hollenbeck, Dale Blasi

Kansas Agricultural Experiment Station Research Reports

Horn flies (Haematobia irritans(L.)) are considered the most important external parasite that negatively affects pasture-based beef systems with losses estimated to exceed $1 billion annually to the U.S. beef industry. Control strategies have relied heavily on insecticide applications to control horn flies and are implemented when the economic threshold of 200 flies/animal have been exceeded. When horn fly populations are maintained below 200 flies/animal by treating them with insecticides then the level of stress annoyance behaviors such as leg stomping, head throwing, and skin twitching decreases while grazing increases. While most stocker operators utilize some type of fly …

Kansas Agricultural Experiment Station Research Reports

Distillers grains are an excellent energy and protein feed source for beef cattle. Corn distillers grains have been fed to beef cattle for many years, but sorghum distillers grains are becoming more popular and may be more cost effective than corn. Sorghum is very comparable to corn in terms of energy, but has a higher crude protein value. All distillers grains are available in a wet and dry form. The moist texture of wet distillers grains can help to reduce sorting at the bunk and appears to improve intake in young calves. The objective of this study was to evaluate …

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 similar density …

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.

Angus Ground Beef Has Higher Overall Consumer Acceptability Than Grass-Fed Ground Beef, F. Najar, E. A. Boyle, T. G. O'Quinn, R. Danler, S. Stroda, L. N. Drey, K. R. Vierck, G. D. Mccoy

Kansas Agricultural Experiment Station Research Reports

Ground beef is considered one of the major sources of animal protein in the U.S., accounting for approximately 40% of beef consumption per capita (USDA, 2011). Consumers’ concern about animal welfare, sustainable production, and low fat products has influenced purchasing decisions, resulting in an increased demand for grass-fed ground beef (U.S. Department of Agriculture, Agricultural Marketing Service, 2007). Grass-fed cattle are fed natural based forages or grass-hay, thus resulting in a higher deposition of omega-3 fatty acids in meat. Meat from grain-fed cattle has a lower omega-3 content due to the saturated and monounsaturated fatty acid profile found in a …

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.

Cleaning Reduces Mycotoxin Contamination In Corn, A. Yoder, M. D. Tokach, J. M. Derouchey, C. B. Paulk, C. R. Stark, C. K. Jones

Kansas Agricultural Experiment Station Research Reports

A single load of corn naturally contaminated with aflatoxin (1,074 ppb), fumonisin (8.3 ppm), and ochratoxin A (206 ppb) was procured from central Oklahoma to evaluate the role of cleaning to remove mycotoxin contamination in corn. Corn was divided into twenty 333-lb lots, which were then cleaned using an EBM Gentle Roll corn cleaner to remove overs (material>1/2 inches) and unders (material<3/16 inches). The resultant 4 treatments included: 1) uncleaned corn; 2) overs from cleaned corn; 3) cleaned corn; and 4) unders from cleaned corn. Samples of each fraction were analyzed for mycotoxin content using multiclass liquid chromatography tandem mass spectrometry.

Cleaning generated approximately 6% screenings (unders + overs), and reduced (P<0.05) aflatoxin by an average of 26%. Cleaning also reduced (P<0.05) fumonisin by 45%, but did not impact ochratoxin A. Unders had nearly 4 times the aflatoxin and 7.5 times the fumonisin as the uncleaned corn. In conclusion, cleaning corn may substantially reduce mycotoxin contamination, but the resultant screenings should be used cautiously.
