    Many people seem to prefer to drink milk when it is cold. Research describing flavor and aftertaste of milk, and then correlating these traits with their chemical composition, has not previously been done. The ...
  • Fox, John A.; Hanawa Peterson, Hikaru (2008-09-24)
    BSE has not been found in the US* but current detection efforts provide little assurance that it does not exist at a low level. The US has taken precautionary measures to reduce the risk of importing the disease and the ...
  • Tiffany, S.M.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-01)
    We compared outcomes of two protocols used to resynchronize estrus and ovulation in dairy females after found open at pregnancy checks. Replacement heifers and lactating cows in which AI occurred 41 ± 1 day earlier ...
  • Harner, Joseph P.; Smith, John F., 1962-; Miller, W.F.; Cvetkovic, B.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-01)
    Lactating dairy cattle were used to evaluate three different cooling systems. Eight cows were arranged in a replicated Latinsquare design and assigned to each of four treatments. Treatments were control, lowpressure soaking ...
  • Harner, Joseph P.; Smith, John F., 1962-; Miller, W.F.; Cvetkovic, B.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-01)
    Seven heat-stressed, lactating Holstein cows were exposed to six different cooling systems to evaluate the effects of air velocity and direction of airflow. Cows were arranged in a 7 × 7 Latin-square design. Six ...
  • Stephens, J.W.; Obuz, E.; Grobbel, J.P.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-08-04)
    In a previous study, eighteen strip loins from USDA Select and premium Choice carcasses were cooked on a Magikitch’n® belt grill to determine tenderness at nine different endpoint temperatures. That study revealed that ...
  • Grobbel, J.P.; Dikeman, Michael E.; Milliken, George A.; Yancey, E.J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-08-04)
    The objective of our study was to evaluate the relationships among total iron content, myoglobin/total iron ratio, hemoglobin/total iron ratio, and flavor attributes in beef top sirloin, shoulder clod, and tenderloin ...
  • Meyer, M. J.; Everett, R.W.; Van Amburgh, M.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-01)
    The primary advantages of reducing age at first calving (AFC) include reducing rearing costs as well as reducing time in which the heifer is only a capital drain on farm resources. The primary disadvantage of reducing AFC ...
  • Francis, L.L.; Lee, J.; Chambers, Delores H.; Jeon, I.J.; Simmons, S.R.; Schmidt, Karen A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-01)
    Various chemical compounds contribute to the naturally pleasant flavor of milk. Over time, however, and with unwanted chemical reactions, loss of flavor is inevitable. This study was conducted to identify and quantify ...
  • Montgomery, Sean P.; Sindt, J.J.; Greenquist, M.A.; Miller, W.F.; Pike, J.N.; Good, E.J.; Loe, E.R.; Sulpizio, M.J.; Kessen, T.J.; Drouillard, James S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-08-03)
    Six hundred sixty-five crossbred beef heifers initially weighing 495 lb were used to evaluate rectal temperature and plasma glucose, lactate, and urea nitrogen at initial processing as indicators of health status of newly ...
  • Titgemeyer, Evan C.; Johnson, B.J.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-01)
