| The objective of this study was to evaluate the reproductive performance of sows artificially inseminated by the intrauterine (IAIU) technique. The experiment was arranged in a randomized complete block design, with 300 sows being distributed in five insemination techniques: control, intra-cervical (IAIC) with 3x10(9) spermatozoa/100 mL; intrauterine (IAIU) with 1x10(9) spermatozoa/100 mL; intrauterine with com 1x10(9) spermatozoa/50 mL; intrauterine with 5x10(8) spermatozoa/100 mL; and intrauterine com 5x10(8) spermatozoa/50 mL. The sows submitted to intrauterine insemination presented a farrowing rate of 90.8% and return to estrus rate of 9.2%, which did not differ from the rates obtained by the intra-cervical technique (90.0% and 10.0%, respectively).... |
