Indagine proteomica del seme bovino per la valutazione della fertilit\ue0

Abstract

Ipofertility is one of the most common problems and main cause of economic losses in dairy production. Bull infertility represent a significant component on unsuccessful pregnancy. In this study, proteomic analysis was applied to compare the sperm protein expression profile from high and low fertility bulls. It has been found that expression of several proteins (9 different 2-D spots) is related to high and low fertility bulls (p<0.05). These proteins are involved in sperm-egg interaction and cell cycle regulation. Proteomic analysis of sperm can be a valuable tool to identify protein changes related to fertility
