dc.descriptionThe 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 3x109 spermatozoa/100 mL; intrauterine (IAIU) with 1x109 spermatozoa/100 mL; intrauterine with com 1x109 spermatozoa/50 mL; intrauterine with 5x108 spermatozoa/100 mL; and intrauterine com 5x108 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). Total litter size did not differ between the techniques, with the means being from 11.4 to 11.9 piglets at farrowing. Although 4.6% of the sows submitted to intrauterine artificial insemination had difficulty with pipette insertion into the cervix, 100% of them were inseminated. When evaluating semen backflow, no difference was found between the intra-cervical and intrauterine insemination techniques. However, total semen backflow was higher in sows submitted to inter-cervical insemination. No difference was found in the presence of blood between the two methods evaluated. Hence, any of the intrauterine insemination techniques can substitute inter-cervical artificial insemination without damaging the reproductive performance of the animals.
dc.descriptionUm experimento foi realizado com o objetivo de avaliar o desempenho reprodutivo de matrizes suínas inseminadas pela técnica intrauterina (IAIU). Em um delineamento inteiramente casualizado, 300 fêmeas foram distribuídas em cinco técnicas de inseminação: controle - intracervical (IAIC) com 3x109 espermatozoides/100 mL; intrauterina (IAIU) com 1x109 espermatozoides/100 mL; intrauterina com 1x109 espermatozoides/50 mL; intrauterina com 5x108 espermatozoides/100 mL; e intrauterina com 5x108 espermatozoides/50 mL. As fêmeas inseminadas pela técnica intrauterina apresentaram taxa de parto de 90,8% e taxa de repetição de estro de 9,2%, que não diferiram das taxas obtidas pela técnica intracervical (90,0% e 10,0%, respectivamente). O total de leitões nascidos não diferiu entre as técnicas, com média geral de 11,4 a 11,9 leitões por parto. Apesar da dificuldade na passagem da pipeta em 4,6% das fêmeas submetidas à inseminação artificial intrauterina, 100% das fêmeas foram inseminadas. Na avaliação da ocorrência de refluxo de sêmen, não houve diferença entre as técnicas de inseminação intracervical e intrauterina. Entretanto, o total de espermatozoides refluídos foi maior nas fêmeas submetidas à inseminação intracervical. A ocorrência de sangramento não diferiu entre as técnicas estudadas. Portanto, qualquer uma das técnicas de inseminação intrauterina pode substituir a inseminação artificial intracervical, pois não comprometem o desempenho reprodutivo dos animais.
