  • Altered insemination timing improves pregnancy rates after a CO-Synch + CIDR protocol
    Dobbins, C.A.; Tenhouse, D.E.; Eborn, D.R.; Johnson, S.K.; Harmoney, K.R.; Stevenson, J.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    Our objective was to determine the optimal time to inseminate lactating beef cows after applying the CO-Synch + CIDR protocol [injection of GnRH given seven days before and 48 to 72 hr after an injection of prostaglandin ...
  • Components of a progressive reproductive management program
    Stevenson, J. S. (Kansas Agricultural Experiment Station, 1993)
    These are somewhat exciting times for dairy producers because of the new arsenal of hormones available for controlling estrous cycles and improving fertility. Using Bovilene® seems to assist cows in releasing a retained ...
  • GnRH removal in the 7-11 CO-Synch for timed insemination of beef heifers
    Eborn, D.R.; Grieger, D.M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    The use of artificial insemination can improve genetics, shorten the calving season, and increase weaning weights by having more calves born earlier in the breeding season. Reasons that this technology has not been used ...
  • Use of milk progesterone and PGF[subscript]2alpha in a scheduled insemination program
    Stevenson, J. S.; Pursley, J. R. (Kansas Agricultural Experiment Station, 1993)
    Holstein cows milked twice daily were assigned to be inseminated at their first detected estrus (control) after 42 days in milk or received PGFza (PG) after 42 days, if they had a high milk progesterone (P4) test on ...
