  • Effects of exposure to boars and other gilts on the estrous response after synchronization with altrenogest
    Davis, D.L.; Stevenson, J.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1984)
    Estrus was synchronized in gilts by feeding altrenogest for 18 days. All gilts were penned in gestation stalls. Beginning the day before the last altrenogest treatment and continuing until 3 days after treatment, gilts ...
  • Litter size in gilts after altrenogest and flushing
    Davis, D.L.; Stevenson, J.S.; Pollmann, D.S.; Allee, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1984)
    Effects of estrous synchronization and flushing on litter size in gilts were compared on two farms. Estrus in gilts was synchronized with altrenogest for 14 days or estrous cycles were left unaltered (control group). ...
  • Successful induction of estrus during lactation for sows separated from their litters
