摘要
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 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.

这项研究的目的是评估母猪的子宫内（IAIU）技术，人工授精的繁殖性能。该实验被安排在一个随机完全区组设计，用300母猪被分布在5授精技术：控制，内颈（IAIC）与3×10 SUP 9 / SUP精子/ 100mL的;宫内（IAIU）与1×10 SUP 9 / SUP精子/ 100mL的;宫内有COM 1×10 SUP 9 / SUP精子/ 50mL的;宫内有5×10 SUP 8 / SUP精子/ 100mL的;宫内COM 5×10 SUP 8 / SUP精子/ 50mL的。提交到宫腔内人工授精的母猪提出了90产仔率。8％，回归到发情率9.2％，而没有从由帧内宫颈技术（分别为90.0％和10.0％），得到的速率不同。总产仔数没有技术之间的差异，用的手段，从11.4到11.9仔猪处于产仔。尽管4。提交宫内人工授精的母猪6％有困难吸管插入子宫颈，其中100％的受精。在评估精液倒流，无差异的内颈及宫腔内人工授精技术之间找到。但是，总的精液倒流在提交给跨宫颈人工授精的母猪高。没有差异，在血液评价这两种方法之间的存在。因此，任何的子宫内授精技术可以替代跨宫颈人工授精而不破坏动物的繁殖性能。
