Effect of Glass Wool and Sephadex Sperm Separation Techniques on Improving the Poor Quality Semen of Iraqi Buffalo Bulls

Abstract

Abstract This study investigated the effect of glass wool and Sephadex separation techniques on improving the poor semen quality of buffalo bulls. Semen had divided into four groups. The first and second groups used good (G1, positive control) and poor-quality semen (G2, negative control). Glass wool (G3) and Sephadex (G4) techniques had used to separate the poor semen quality in the 3rd-4th groups, respectively. The sperm concentration and total abnormalities were lower in the G3 and G4 groups than in the G2 group. Motility increased in the G4 group compared to the G2 group. Live sperm, normal morphology, plasma membrane, and acrosome integrity were higher in groups G4 and G3 than in the G2 group. In conclusion, after separation, there was a decrease in sperm concentration compared to non-separation. This decrease had compensated by a proportionate increase in other semen characteristics, which may improve the conception rate via artificial insemination with filtered semen.
