This research was carried out into a commercial sows farm, located on Zona da Mata of state Minas Gerais, in order to evaluate the decreasing effect of the volume and the spermatic content between the traditional (ICAI) and the intrauterine insemination (IUAI) procedure, assess the introduction of the intrauterine insemination catheter, estimate the seminal backflow and the bleeding occurrence in the inseminated females by the both techniques. In a completely design, 300 females randomly distributed into 60 females in each one of the 5 treatments: T1 (control) intracervical with 3x109 spermatozoa/100 mL; T2 intrauterine with 1x109 spermatozoa/100 mL; T3 intrauterine with 1x109 spermatozoa/50 mL; T4 intrauterine with 5x108 spermatozoa/100 mL and T5 intrauterine with 5x108 spermatozoa/50 mL. The females inseminated by the IUAI technique showed the pregnancy general media rate of 95,0%, 90,8% farrowing rate and 9,2% return to the estrus. This results revealed none significant difference in comparison to the ICAI technique (91,7%, 90,0% and 10,0% respectively). The total litter size did not differ (p>0,05) between the IUAI and ICAI, and the average rates were 11,5, 11,7, 11,4, 11,9 and 11, 4 piglets in the treatments 1, 2, 3, 4 and 5 respectively. Although 4,6% of the achieved IUAI presented a subtle difficulty in the passage by cervix, the catheter was successfully inserted in 100% of females. There was no difference in the sperm backflow occurrence between the both methods. However, the ICAI demonstrated semen backflow rate of 85,8% of the injected volume, containing about 26% of the inseminated sperm content while in the IUAI the backflow diverge from 83,0% to 90,6% of the volume presenting 11,1% - 16,4% of the spermatozoa content. The percentual of the backflow volume did not show difference (p>0,05) between the treatments, on the other hand the spermatozoa content in the ICAI backflow collected was higher than in the IUAI. There was no difference (p>0,05) about the presence of blood in the both insemination procedure. Thus, these results indicate that the two treatments, applying a reduced volume and spermatozoa content, by the IUAI technique would be adopted in the commercial farm daily routine without compromising the female swine reproductive performance.
