  • Kuhl, Gerry L.; Goehring, T.; Ritter, B.; Laudert, S.; McCully, W. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-12-03)
    Several spaying and ovarian autografting methods were tested in three field trials with 658 grazing heifers. None of the techniques examined were found to have a beneficial effect on heifer gains compared to intact ...
  • Eck, T.P.; Corah, L.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-10-14)
    Feedlot performance of steers implanted with Compudose®, Implus-S®, or Synovex-S® was very similar. No statistical differences were detected among treatments. However, implanted steers gained an average of 4% faster ...
  • Thompson, L.K.; Schneider, C.; Parsons, G.; Miller, K.; Reinhardt, Christopher D.; Drouillard, James S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2011-03-30)
    Using a growth promotant at the correct time of finishing is critical for maximizing profit potential. Previous studies have shown that zilpaterol-HCl (Zilmax; Intervet/ Schering-Plough Animal Health, Millsboro, DE) ...
  • Smith, J.M.; Corah, L.R.; Lamb, G.C.; Spell, A.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-10)
    The objective of this project was to study the effects on pregnancy rates of inseminating estrus-synchronize d heifers either at observed estrus or at a fixed time. In April, 1994, 574 yearling crossbred heifers, located ...
  • Hoffman, D.P.; Krehbiel, C.L.; McKee, R.M.; Stevenson, Jeffrey S.; Nichols, David A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-09-10)
    One disadvantage of most estrous synchronization programs is their inability to induce cycling in prepubertal heifers and anestrous suckled beef cows. Suckled cows and virgin heifers were treated with PG F2", norgestomet, and ...
  • Bolze, R.P.; Peters, C.W. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-10-05)
    Injectable estradiol (estradiol benzoate) was evaluated for its effect on the reproductive performance of yearling beef heifers whose estrous cycles were synchronized using the melengestrol acetate/prostaglandin F 2 α ...
  • Jones, S.Q.; Marston, T.T.; Kraus, T.J.; DeRouchey, Joel M.; Waggoner, Justin W.; Breiner, Ryan M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2011-03-30)
    Many factors affect forage quality, including moisture level at baling, compaction, bulk density, and maturity at harvest. Losses of dry matter and nutrient value occur during field curing. Hay baled at or above 18% ...
  • Corah, L.R.; Yaeger, J.R.; Whittier, J.C.; Meiske, J.C.; Patterson, D.J.; Olson, K. C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-10-14)
    We evaluated the estrous response and fertility of yearling beef heifers after treatment with melengestrol acetate (MGA) and prostaglandin F2" (PG). The 304 heifers, at three locations, were allotted to two ...
