A Comparison Of Flavor And Tenderness Between Dry-Aged And Vacuum-Aged Beef Strip Loins, K. Warren, Curtis L. Kastner Jan 1989

A Comparison Of Flavor And Tenderness Between Dry-Aged And Vacuum-Aged Beef Strip Loins, K. Warren, Curtis L. Kastner

Kansas Agricultural Experiment Station Research Reports

Starting 3 days postmortem, sections from eight USDA Choice or better, yield grade 4, strip loins were dry-aged (aged unpackaged) or vacuum-aged (aged in vacuum bags) for an additional 11 days. The dry-aged loins lost more (P<.05) weight during aging than vacuum-aged loins, and cooked faster, with less (P<.05) cooking loss than the unaged loins. Vacuum-and dry-aged samples were similar (P>.05) in tenderness, and both were more tender (P<.05) than unaged counterparts. A trained taste panel found no differences in subcutaneous fat flavor. However, lean from the vacuum-aged samples had a more intense sour flavor note and more intense bloody/serumy flavor and metallic notes than either of the other treatments. The lean of dry-aged samples was beefier and had more brown/roasted flavor than vacuum-aged or unaged counterparts.


Performance, Carcass, And Meat Palatability Traits Of Open And 30-Month Old Heifers That Produced One Calf, A.W. Waggoner, J.R. Brethour, Michael E. Dikeman Jan 1989

Performance, Carcass, And Meat Palatability Traits Of Open And 30-Month Old Heifers That Produced One Calf, A.W. Waggoner, J.R. Brethour, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Eighty-seven 3/8 Simmental x 5/8 Hereford heifers calved at 2 years of age and were designated as Single-Calf-Heifers (SCH). Twenty-six heifer mates that did not calve were designated as 2-year-old open heifers (2-OH), and 22, 1 year-old open heifers (1-OH) from the same source served as controls. All heifer groups were fed a high-grain diet for 112 to 137 days before slaughter. The SCH were started on feed about 1 month after calving, and their calves were weaned early about 5 weeks prior to slaughter. Thirty-three of the SCH were implanted with Synovex-H® after calving. Carcass data were ...


Liver Fluke Infestation In Kansas Fed Slaughter Cattle, S.B. Laudert Jan 1989

Liver Fluke Infestation In Kansas Fed Slaughter Cattle, S.B. Laudert

Kansas Agricultural Experiment Station Research Reports

Feedlot cattle from 1,687 pens totaling 290,183 head were evaluated at slaughter for the presence of liver flukes. Overall, 4.92% of the cattle were found to be infected. Only 15.2% of all pens of cattle were found to be completely free of flukes. However, only 5.3% of the pens had greater than 15% of the cattle infested. Beef steers had a higher level of infestation (5.2%) than beef heifers (4.4%). Holstein steers had an overall infestation rate of 4.4%.


Fecal Thiaminase In Feedlot Cattle, T.D. Hays, B.E. Brent Jan 1989

Fecal Thiaminase In Feedlot Cattle, T.D. Hays, B.E. Brent

Kansas Agricultural Experiment Station Research Reports

Fecal thiaminase was measured on 152 feedlot cattle at three locations and on a variety of rations. No animals showed signs of polioencephalomalacia. Thiaminase activities ranged from 0.6 to 430 µmol thiamin destroyed per minute per liter of feces (µmol/min/l). Eighty-two percent of the thiaminase activities were below 20 µmol/min/l, and only 3 percent were less than 2 µmol/min/l. High levels of fecal thiaminase were apparently not related to ration. Thiaminase was detected in all animals studied, but one location had only minimal levels. When high levels of thiaminase were found, the samples ...


Managing Fast- Vs. Slow-Growth Genotypes To Optimize Quality And Yield Grades, R.R. Schalles, K.O. Zoellner, Michael E. Dikeman Jan 1989

Managing Fast- Vs. Slow-Growth Genotypes To Optimize Quality And Yield Grades, R.R. Schalles, K.O. Zoellner, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Fast-growth genotype steers placed on a high energy ration a month after weaning were compared to a slow-growth genotype on a growing ration for 155 days, followed by a finishing ration for 62 days. The fast-growth genotype produced heavier, higher quality carcasses in less time than the slow-growth genotype, with similar energy conversion. Using contemporary prices. the fast-growth genotype cattle broke even, and the slow-growth genotype lost $124 per head.


Effects Of Finapux® In Combination With Ralgro® And Synovex® On Performance And Carcass Characteristics Of Steers And Heifers, Gerry L. Kuhl, D. Simms, R. Ritter, P. Houghton, Paul D. Hartman Jan 1989

Effects Of Finapux® In Combination With Ralgro® And Synovex® On Performance And Carcass Characteristics Of Steers And Heifers, Gerry L. Kuhl, D. Simms, R. Ritter, P. Houghton, Paul D. Hartman

Kansas Agricultural Experiment Station Research Reports

Five field trials were conducted with 762 steers and heifers to evaluate Finaplix® in combination with Ralgro® or Synovex® for growing and finishing programs. Effects on cattle performance and carcass characteristics were inconsistent across trials. However, in general, implanting cattle with Finaplix and either Ralgro or Synovex tended to result in increased gain, final weight, and carcass weight, with little effect on backfat, loin eye area or kidney, heart, and pelvic fat. Marbling score and the percentage of cattle grading choice tended to be reduced slightly, although this was not usually significant.
