| Popis: | The post-cervical artificial insemination (PCAI) in sows increases semen performance compared to cervical artificial insemination (CAI). In Argentina the use of the PCAI is restricted to multiparous while it is not applied to nulliparous. The aim of this study was to compare porcine CAI and PCAI in nulliparous and multiparous. Pregnancy rates and number of live pups with CAI and PCAI in nulliparous and multiparous, assessing advantages and disadvantages of each method were compared. This is a small-scale work (4 CAI and 7 PCAI in nulliparous, 3 CAI and 3 PCAI in multiparous) in a small field productive site in the Province of Buenos Aires. Here the boar was omitted for heat detection and to stimulate the sow during AI. Pregnancy rates and the number of pups born alive per pregnant sow were similar with the two techniques and two categories. The PCAI is a good practice in nulliparous and multiparous because this technique increases semen performance compared to CAI and it is omitted the presence of the boar. |
