  • Ovarian responses and conception rates in response to gNrh, Hcg, and progesterone
    Stevenson, J.S.; Portaluppi, M.A.; Tenhouse, D.E.; Lloyd, A.; Eborn, D.R.; Kacuba, S.; DeJarnette, J.M (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 ...
  • Relationships between live animal ultrasound predicted intramuscular fat and shear force in fed cattle
    Keenan, L.D.; Moser, D.W.; Eborn, D.R.; Marston, T.T. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)
    Approximately 280 Simmental- and Hereford- sired feedlot steers were ultrasonically evaluated for intramuscular fat deposition using CPEC and Critical Vision, Inc. (CVI) ultrasound systems. Warner-Bratzler shear force ...
  • Short-term progestin estrus synchronization with timed insemination for beef heifers: CIDR vs. MGA
    Thompson, A.W.; Eborn, D.R.; Keenan, L.D.; Grieger, D.M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Recently, a new product, Eazi-Breed CIDR (a vaginal insert containing progesterone), was approved for estrus synchronization in beef heifers. In previous studies the CIDR has produced excellent estrus synchrony, but it ...
  • Timed artificial insemination in yearling beef heifers: 7-11 Cosynch VS. Cosynch
    Thompson, A.W.; Holladay, C.D.; Eborn, D.R.; Grieger, D.M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)
    Previous research demonstrated that an estrus-synchronization program using a short period of melengestrol acetate (MGA) feeding in conjunction with a Cosynch protocol was effective in synchronizing estrus in postpartum ...
  • Timed-insemination of beef heifers using Cosynch with one or two initial injections of GnRH
    Grieger, D.M.; Holladay, C.D.; Eborn, D.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    Our purpose was to determine if giving an additional injection of GnRH to beef heifers synchronized with the Cosynch protocol would increase pregnancy rate to timed A.I. Eighty yearling beef heifers received an injection ...
