    A multi-location study was conducted using suckled beef cows in Minnesota and Kansas to test the benefit of adding a source of progestin to the Cosynch ovulation synchronization protocol (injections of GnRH, 7 days ...
  • Short-term feeding of MGA to postpartum cows prior to the breeding season
    Gleghorn, J.F.; Marston, T.T.; Wanket, L.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    A protocol to make anestrous cows more likely to cycle prior to estrous synchronization would greatly enhance reproductive efficiency. Ease of application, availability, and low cost make feeding melengestrol acetate ...
  • Timed-insemination of beef heifers using Cosynch with or without MGA
    Grieger, D.M.; Wickersham, T.A.; Cochran, R.C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    Our purpose was to determine if feeding melengesterol acetate (MGA) for 1 week in combination with gonadotropin-releasing hormone (GnRH) and prostaglandin-F2" (PGF) would better synchronize heifers for timed artificial ...
