Título em português: Progestágeno intravaginal para controle do estro e do parto em fêmeas suínas.  aThe objective of this work was to evaluate the use of intravaginal devices (IVD) for the control of reproductive events in swine. Sows at 112 days of pregnancy received an injection of PGF2á (control, n = 15) or PGF2á plus an IVD containing medroxyprogesterone acetate (IVD group, n = 14) for 48 hours. Sows initiated labor 27.7±1.6 and 82.3±3.8 h after PGF2á aplicaction, in control and treated groups, respectively. Regarding control of estrus cycle, ten sows received IVD for 12 days starting immediately after weaning, and estrus was confirmed 17.25±0.17 days after weaning, in comparison to 4.00±0.25 days for the control group. Intravaginal devices with progestagen can be applied for the control of reproduction in swine.  aLabor  aProgestational hormones  aParto  aDispositivo intravaginal  aGestágenos  aIntravaginal device  aReprodução de suíno  aSwine reproduction1 aFRELING, G.
