RESUMO
Addition of 2.5 mM vitamin C or 40 mM of glucose to washed buffalo spermatozoan suspensions in Ca2(+)-free Kreb's Ringer Hanseliet saline buffer (pH 7.0) resulted in significant lower malonaldehyde concentration and higher spermatozoan motility and liver spermatozoa compared to control levels after 45 min of aerobic incubation at 37 degrees C or pre-incubation levels.

Vitamin E significantly (P less than 0.01), inhibited lipid peroxidation as indicated by malonaldehyde (MDA) production and improved significantly (P less than 0.01) motility and percent live spermatazoa of B. bubalis semen. Bulls with higher MDA formation had lower sperm motility and percent live count. Variance due to bulls for all the three parameters were significant (P less than 0.05).
