Efeito do tempo pós-abate na viabilidade dos espermatozóides recuperados do epidídimo em Bodes

Abstract

Sperm retrieval from the epididymal tail is a technique used to preserve the genetic material of animals of great zootechnical value, especially in situations of sudden death. The objective of this study was to evaluate the effect of time after slaughter on the quality of sperm recovered from the epididymal tail of goats. Ten pairs of testes were used along with epididymis obtained from goats acquired in the informal market of "Xiquelene", immediately after slaughter and sent to the Reproduction Laboratory at the Faculty of Veterinary Medicine in a styrofoam box with ice. In the laboratory, they were subjected to different semen retrieval time intervals of one, three, five and seven hours. The semen was retrieved by the incision method, and the following parameters were evaluated: mass, individual and supravital motility. The results obtained in this study revealed that sperm cells remain viable for up to 5 hours. This study is of great importance, as it can contribute to genetic conservation strategies in assisted reproduction programs in goats(TRADUÇÃO NOSSA)
