Abstract

The search for new technologies to improve sheep production has become very important, especially in reproduction. Taking into account the stud and its importance for a good reproductive success within a flock, new ways of evaluating semen quality are being developed. The two-dimensional electrophoresis in polyacrylamide gel has been used to describe and characterize proteins in seminal plasma of several species. Some of these proteins are related to motility, viability and fertility of spermatozoa. This work was carried out with 10 players race Dooper, semen was collected by artificial vagina and this sampled to test the physical, morphological and SDS-PAGE. Due to several factors, it was not possible to identify proteins in seminal plasma, and thus not possible to establish a correlation with the morphology of sperm. But several morphological problems, particularly the tail strongly folded, disqualify animals as breeding second seminal patterns for the species. Objective - to work on the following analyze the protein profile of seminal plasma of sheep and their relationship with sperm morphology
