Determinación de la eficiencia de dos técnicas de inseminación artificial en cerdas: Intracervical e intrauterina en la granja Buenos Aires, Santa Elena.

Abstract

The present research objective was to determine the efficiency for artificial insemination techniques both intracervical and intrauterine in adult female pigs at the “Buenos Aires' ' farm in Santa Elena. The sample was made of 60 adult female pigs (between 3 and 4 deliveries) of line PIC 337, an average weight of 200,0 kilograms. A completely random model was applied with a combination of factors arrangement, where Factor A corresponded to the insemination technique and Factor B corresponded to the number of deliveries. The size of each experimental unit was of one adult female pig, with 15 others with the same treatment. The female pigs inseminated with both techniques (intracervical and intrauterine) at the “Buenos Aires' ' farm in Santa Elena, presented the following reproductive responses. It total, the number of piglets born as a result of the intracervical insemination were 14,73 and for the intrauterine 13,73; in relation to the number of piglets born alive 13, 67 and 13,50 for the intracervical and intrauterine respectively; the average of piglets born dead 0,67 for the intracervical technique and 0,03 for the intrauterine. It was concluded that the female pigs inseminated with both intracervical and intrauterine techniques had the following reproductive results: average length of gestation 116,50 days and 116,27 days for the corresponding described techniques. Besides, 100.0% of the inseminated pigs were successfully conceived. The use of intrauterine technique was recommended at the “Buenos Aires' ' farm in the Santa Elena province, because it resulted in higher economic profitability in comparison to the cervical technique.
