Resumo
The experiment compared the pregnancy rates in sheep submitted to IA, to evaluate the influence ofsperm concentration on fertility rate in sheep inseminated with frozen semen. In experiment run 37 females wereused, subject to synchronization of estrus and divided into two groups: G1 (n = 19), using artificial inseminationwith a concentration of 200 million viable spermatozoa and G2 (n = 18), using artificial insemination is at aconcentration of 100 million sperm. Pregnancy rates were 66.66% and 77.77% in sheep that were inseminatedwith the concentration 200 and 100 million sperm respectively transcervical and the sheep that have beeninseminated by laparoscopy at the same concentrations as pregnancy rates were 50% and 77.77% respectively.The concentrations used have shown - is quite effective when compared pregnancy rates in each group. Butneeds more in vivo studies.(AU)
