  • Portaluppi, M.A.; Tenhouse, D.E.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    Our objective was to determine whether delaying the PGF2α injection by 24 or 48 hr after the first GnRH injection in an Ovsynch protocol (from a standard 7 days) altered ovar-ian characteristics in lactating dairy cows. ...
  • Awawdeh, M.S.; Titgemeyer, Evan C.; Drouillard, James S.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    Thirty-two multiparous Holstein cows (152 days in milk, producing 90 lb/day of milk at the beginning of the study) were used in a 4 × 4 Latin square design with 28-day periods to investigate cow responsiveness to supple-mental ...
  • Harner, M.J.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    Efficient utilization of nutrients is a must on modern dairies. Most of the phosphorus arriving at the dairy will either be found in purchased feedstuffs or commercial fertilizer used to raise grain and forage for the ...
  • Smith, J.F.; VanBaale, M.; Jamison, C.; Rodriguez, R.; Harner, Joseph P.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    A project to evaluate the degree of heat stress in individual dairies was carried out in the summer of 2005. The object of this project was to develop a method to evaluate or audit how effective an individual dairy is in ...
  • Awawdeh, M.S.; Titgemeyer, Evan C.; Drouillard, James S.; Beyer, R. Scott (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    Evaluations of four soybean meal (SBM) products were conducted. The products were: solvent SBM (SSBM), expeller SBM (ESBM), lignosulfonate-treated SBM (LSBM), and SSBM treated with 0.05% Baker’s yeast and toasted at 212ºF ...
  • Harner, Joseph P.; Smith, J.F.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    A model was developed to evaluate the impact of facilities on cow time budgets. The model suggests that in inadequate facilities overcrowding of the facility by 25% or more resulted because occupancy rate exceeded 100%. ...
  • Julstron, L.F.; Schmidt, Karen A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    Packaged, reduced-fat milk was subjected to a 20 min/day temperature cycle during a 7-day refrigeration period to determine the ef-fect on milk quality. Temperature cycling did not affect the compositional or microbial ...
  • Portaluppi, M.A.; Tenhouse, D.E.; Lloyd, A.; Eborn, D.R.; Kacuba, S.; DeJarnette, J.M; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    We hypothesized that increasing concentrations of progesterone after artificial insemination (AI) would increase fertility. Our objective was to assess changes in ovarian structures, incidence of ovulation, and change in ...
  • Buttrey, B.S.; Burns, M.G.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    Experiments have shown human chorionic gonadotropin (hCG) to be more effective than GnRH as a means to induce ovulation of folli-cles. Dosages used, however, have differed greatly among experiments. A study was per-formed ...
  • Smith, J.F.; Grigsby, K.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    Forty lactating Holstein cows were allocated into groups of 5 cows each and assigned to 8 pens containing 10 freestalls each. Each group contained 3 heifers and 2 multiparous cows. Groups were balanced by milk production ...
  • Portaluppi, M.A.; Tenhouse, D.E.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    Our objectives were to determine various factors influencing upfront single and multiple ovulation in response to GnRH in a timed arti-ficial insemination (TAI) protocol and subse-quent fertility after altering timing of ...
