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)
