  • Cvetkovic, B.; Shirley, John E.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Twenty-four lactating Holstein cows were used to determine the production response to the inclusion of brown seaweed in the basal diet during summer heat stress. Cows were blocked by lactation number, days in milk, and ...
  • Armstrong, D.V.; Smith, J.F.; Wuthironarith, V,; Harner, Joseph P.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Ten multiparous lactating Holstein cows were arranged in a replicated 5 × 5 Latin Square design to evaluate the effect of soaking frequency and volume of water per soaking on lactating cows housed in a tunnel-ventilated and ...
  • Phatak, A.P.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    A controlled field study examined conception rates after two timed-AI (TAI) breeding protocols conducted on two commercial dairy farms. Estrous cycles in postpartum lactating cows were presynchronized with two ...
  • Hollis, Larry C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Johne’s disease was characterized as a significant disease in cattle before the start of the 20th century. The disease causes a chronic wasting away and non-responsive diarrhea, coupled with a long incubation period ...
  • Titgemeyer, Evan C.; Johnson, B.J.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    We evaluated the effect of supplementing typical dairy diets with yeast and fibrolytic enzymes on dairy cow performance. Twentyfour Holstein cows were used to evaluate the effects of yeast (Procreatin-7, a live culture ...
  • 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, 2004)
    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 ...
  • Meyer, M. J.; Everett, R.W.; Van Amburgh, M.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    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 ...
  • Harner, Joseph P.; Smith, J.F.; Miller, W.F.; Cvetkovic, B.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    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 ...
  • Harner, Joseph P.; Smith, J.F.; Miller, W.F.; Cvetkovic, B.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    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 ...
  • Tiffany, S.M.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    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 ...
  • Francis, L.L; Kong, S.H.; Chambers, Delores H.; Jeon, I.J.; Simmons, S.R.; Schmidt, Karen A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    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 ...
