The reproductive planning a squad, using natural breeding (MN), can be carried out to the maximumuse of animals (Campos, 2008). However there are practical to provide improvements in the system, such asartificial insemination (AI). twelve were used sows with an average age of two years. Pregnancy diagnosis wasperformed 30 days after the procedure. The arrays were divided into two groups, six were subjected to the IA-six(MN). The pregnancy rate was 66.67% and the rate of return to estrus was 33.33% for both treatments (P>0.05), with no significant difference. The AI in pigs shows satisfactory results in the northeast of Pará, whichprovides the producer, recognize that the method is the most profitable because it reduces the number of animalsin the herd, reducing environmental impacts and risks of transmission of sexually transmitted diseases.(AU)
