Effect Of Information And Information Source On Consumer Preference For Food Irradiation, John A. Fox, Michael A. Boland, W. Grady Jan 2003

Effect Of Information And Information Source On Consumer Preference For Food Irradiation, John A. Fox, Michael A. Boland, W. Grady

Kansas Agricultural Experiment Station Research Reports

The effect of consumer information about food irradiation and the source of the information was studied through a survey mailed to 400 residents each of Manhattan and Topeka, Kansas. Two-thirds of the surveys contained a brochure providing answers to frequently asked questions about irradiation, one-third did not. Half of the informational brochures were altered to suggest they were from industry, half from the government. The survey questioned consumer choice between irradiated and non-irradiated ground beef patties, with price differentials from 10 cents/lb to 40 cents/lb costlier for irradiated patties. A greater price differential resulted in less preference for irradiated beef …

Evaluation Of Consumer Reheating Methods For Destruction Of Listeria Monocytogenes In Frankfurters, M.T. Ortega, H. Thippareddi, Randall K. Phebus, James L. Marsden, Curtis L. Kastner

Kansas Agricultural Experiment Station Research Reports

The USDA Food Safety and Inspection Service has issued a "zero tolerance" for Listeria monocytogenes in ready-to-eat meat and poultry products. The Food Safety and Inspection Service recommends that consumers "Reheat [hotdogs] until steaming" to reduce the risk of listeriosis. We evaluated L. monocytogenes survival on inoculated frankfurters after reheating using common, in-home consumer practices. Frankfurters were inoculated with a six-strain mixture of L. monocytogenes to an initial level of approximately 107 colony forming units (CFU)/gram. Eight inoculated franks for each treatment were cooked using boiling water, a conventional electric oven, or a microwave oven. L. monocytogenes recovery was calculated …

Genetic Relationships Of Body Condition Score With Carcass Traits In Limousin Cattle (2003), D.R. Eborn, Daniel W. Moser Jan 2003

Genetic Relationships Of Body Condition Score With Carcass Traits In Limousin Cattle (2003), D.R. Eborn, Daniel W. Moser

Kansas Agricultural Experiment Station Research Reports

Field data from the North American Limousin Federation was used to determine the heritability and genetic correlations of body condition score (BCS) with carcass traits. Carcass traits included carcass weight, ribeye area, fat thickness, intramuscular fat, and % kidney, pelvic, and heart fat, and all were estimated to be lowly to moderately heritable (0.14 to 0.34). Heritability of BCS was 0.19. Favorable correlations existed between ribeye area and carcass weight (0.50), ribeye area and BCS (0.60), and carcass weight and BCS (0.28). Unfavorable correlations existed among ribeye area and intramuscular fat (-0.40), carcass weight and intramuscular fat (-0.23), and intramuscular …

Relationships Between Live Animal Ultrasound Predicted Intramuscular Fat And Shear Force In Fed Cattle (2003), L.D. Keenan, Daniel W. Moser, D.R. Eborn, T.T. Marston

Kansas Agricultural Experiment Station Research Reports

Approximately 280 Simmental- and Hereford- sired feedlot steers were ultrasonically evaluated for intramuscular fat deposition using CPEC and Critical Vision, Inc. (CVI) ultrasound systems. Warner-Bratzler shear force measurements were taken on steaks from the 13th rib region. Differences between CPEC and CVI ultrasound and actual marbling measurements were corrected for bias and identified as CPEC deviation and CVI deviation. Correlation coefficients and linear models were used to determine if shear force values were associated with amount of intramuscular fat predicted by the ultrasound systems. Correlation coefficients of CPEC deviation and CVI deviation with shear force were 0.18 and 0.15, respectively. …

Rate Of Bloom Of Beef Longissimus Lumborum: Effects Of Muscle Temperature, Age, And Oxygen Exposure Time (2003), C.M. Trater, Melvin C. Hunt Jan 2003

Rate Of Bloom Of Beef Longissimus Lumborum: Effects Of Muscle Temperature, Age, And Oxygen Exposure Time (2003), C.M. Trater, Melvin C. Hunt

Kansas Agricultural Experiment Station Research Reports

Steaks from 12 loins were used to determine the best time and temperature combinations for blooming (development of a bright-red color) of the longissimus muscle at 2, 14, and 26 days postmortem. The lowest temperature (28°F) provided the fastest rate of bloom when the muscle was 2 days postmortem, and 30 minutes were needed to achieve 75% of final bloom color. For meat 14 days old, greater bloom occurred at 35 and 40°F than at 28°F. For meat 26 days old, rate of bloom was equal at all three temperatures. Thus, packers should bloom carcasses one-half hour at 28°F before …

Consumer Valuation Of Steaks With Different Quality Attributes, T. Feldkamp, J. Lusk, Ted C. Schroeder Jan 2003

Consumer Valuation Of Steaks With Different Quality Attributes, T. Feldkamp, J. Lusk, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

Determining needs and wants of consumers is important for the beef industry to reverse the downward trend in beef demand during the last two decades. This study used experimental auctions in conjunction with a survey to determine consumer preferences for beef steaks. Four experimental auctions were used to elicit consumers' maximum willingness to pay for five steak types: generic, guaranteed tender, "natural", USDA Choice, and Certified Angus Beef (CAB). Consumers indicated flavor and tenderness were the most important factors when eating steaks, but they believed there was only about a 50% chance a generic steak would adequately meet these criteria. …

Effect Of Feeding Conventional Or High-Moisture, Steam-Flaked Corn To Finishing Heifers, J.J. Sindt, T.J. Kessen, M.J. Sulpizio, E.R. Loe, Sean P. Montgomery, James S. Drouillard Jan 2003

Effect Of Feeding Conventional Or High-Moisture, Steam-Flaked Corn To Finishing Heifers, J.J. Sindt, T.J. Kessen, M.J. Sulpizio, E.R. Loe, Sean P. Montgomery, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Finishing heifers were fed diets containing either conventional (18% moisture) or high-moisture (36% moisture) steam-flaked corn. Increasing moisture concentration in flakes increased starch availability (P<0.01), but feeding heifers high-moisture flakes decreased (P<0.05) dry matter intake and average daily gain compared to heifers fed conventional flakes. Feeding heifers high-moisture flakes also numerically reduced hot carcass weight and ribeye area, but caused (P<0.01) heifers to deposit more fat over their 12th rib. Extreme levels of moisture in flaked corn improve starch availability but do not appear to increase heifer performance or carcass value. The interaction between moisture and flake density needs further evaluation.

Particle Size Of Corn In Lactation Diets For Mixed-Parity Sows (2003), E C. Baudon, Joe D. Hancock, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

A total of 107 mixed-parity sows (parities one to four) was used to determine the effects of particle size of corn in lactation diets on sow and litter performance. The sows were fed corn-soybean meal-based diets with targeted corn particle sizes of 1,500, 900, and 600 μm (actual means particle sizes of corn during the experiment were 1,600, 824 and 619 μm). Reducing mean particle size of the corn in lactation diets from 1,500 to 600 microns resulted in greater ADFI and water usage (linear effects, P<0.02), fewer days for return to estrus after weaning (linear effect, P<0.04), and less backfat loss (quadratic effect, P<0.03) for the sows. Although the trends in pigs weaned per litter, piglet survivability, litter weaning weight, and litter weight gain were in the same direction as those for feed intake and water usage in the sows, the difference in measurements of litter performance was not statistically important among treatments (P = 0.15 or greater). Intakes of DM, N, and GE by the sows were increased by 9, 4, and 7% and apparent digestibilities of DM, N, and GE were increased by 6, 5, and 7%, respectively, as particle size of corn was decreased from 1,500 to 600 μm (linear effects, P<0.001). Finally, excretion of DM and N in the feces was decreased (linear effect, P<0.002) by 178 g/d and 5 g/d, respectively, as particle size of the corn on the sow diets was reduced. In conclusion, reducing particle size of corn did not affect litter performance but increased feed intake and digestibility of nutrients and reduced nutrient excretion in sows.; Swine Day, 2003, Kansas State University, Manhattan, KS, 2003
