Over the last few years, the good quality poor freezable semen was
not utilized effectively due to less knowledge about the
freezability of semen. There are many reasons, the sperm becomes
poor freezable and one is the lack of sufficient antioxidants in
the seminal plasma and semen extender. The antioxidant content is
reduced during the cryopreservation process and causes premature
cryocapacitation and modification of sperm membrane structure upon
thawing. So study of the pre-freezing and post thaw seminal
parameters like viability, motility, acrosomal integrity, lipid
peroxide assay, vanguard distance traveled by sperm, mitochondrial
membrane potential, velocity and motility parameters (CASA) and
field fertility trial were helped to assess the effectiveness of
the additives. The conception rate was better in reduced
glutathione than cysteine hydrochloride treated group. The
glutathione has improved the poor freezable and maintained the good
freezable semen with regards to the freezability.Thus enhanced the
field fertility rate and in turn helped to prevent wastage of good
quality germplasm and repeat breeder syndrome in cows.
