Identificação de proteínas do plasma seminal de touros da raça Gir

It was studied the seminal plasma total protein (TP) and heparin binding protein (PLH) profiles of Gyr bulls and their associations with andrological parameters and in vitro fertility. Total protein concentration varied between 4,1 a 167,9 mg/ml and heparin binding protein 0,02096 to 0,19025 (%). Chromatographic profile of TP presented nine peaks. PLH presented five affinity peaks. Associations were for: total proteins x blastocysts rate, peak 1 heparin binding proteins x blastocysts rate, peak 5 heparin binding protein x cleavage rate and blastocysts rate. However no protein showed association with andrological parameters.
