| Descripció: | The present study was to evaluate the effect of catheter types, cervical artificial insemination (CAI) or intracervical (IC) and post-CAI or intrauterine (IU), on first calving and multiparous sows on production and reproduction variables. There was an effect (P < 0,05) of catheter type (IU or CI) over the weaned piglets (11,61 ± 0,29 and 10,85 ± 0,33, respectively) and the weaning litter weight (78, 28 ± 2.47 and 68,80 ± 2,85, respectively), in both the sows inseminated with intrauterine catheter presented higher values than the ones inseminated with intracervical catheter. In addition, an effect (P < 0,05) of calving order (multiparous or first calving) was found on piglets born alive, stillborn piglets (2,26 ± 0,32 and 1,45 ± 0,52, respectively), total of born piglets (14,34 ± 0,43 and 12,54 ± 0,68, respectively), litter weight at birth (16,11 ± 0,39 and 13,95 ± 0,62, respectively), and weaning weight (76,40 ± 2,01 and 70,68 ± 3,20, respectively). The multiparous sows showed higher values than first calving ones. There was no effect (P > 0,05) of interaction catheter type-calving order on the variables analyzed. |
