AVALIAÇÃO DO DESEMPENHO REPRODUTIVO EM SUÍNOS ENTRE AS TÉCNICAS DE INSEMINAÇÃO ARTIFICIAL PÓS-CERVICAL E INTRACERVICAL

Abstract

The aim of this study was to evaluate the reproductive performance in swine using two artificial insemination techniques. Were used 60 animals overall, the breed was DB 90 (DanBred) the average of the age was 22 months than weight 210 kg. The experimental delimitation was divided into two groups, which one containing 30 animals, randomly. The first group the animal were inseminated with post-cervical artificial insemination technique, with 1.5 billons of spermatozoa in 50 ml, and in the second group was executed the intracervical artificial insemination technique, with 3 billons of spermatozoa in 80 ml. The statistic was not parametric analyze (Kruskal-Wallis) and test of de averages by Student-Newman-Keuls (p< 0.05). The number of return to estrus was 2 in both groups (postcervical artificial insemination vs intracervical artificial insemination), the number of abortions (0 vs 2), the number of farrow (28 vs 26), the farrowing rate (93.33% vs 86.68%), and the litter size (14.07 vs 14.10), respectively. The post-cervical artificial insemination, showed similar results comparing with the intracervical artificial insemination. We conclude that the postcervical technique has several possible advantages for the producer, being possible the reduction of 40% to 45% of reproducers on the squad.
