This study is focused to look into the possibility of including amino acids during cryopreservation to improve the quality of frozen semen in sheep. Cauda epididymal semen was collected from 2-3 year-old Bannur crossbred rams slaughtered at the local abattoir. The semen samples were diluted in tris egg yolk glycerol diluent along with different additives and made into 7 aliquots. Aliquot 1 served as control, L-alanine was added @ 100 and 135mM in the aliquot 2 and 3, L-glutamine was added @ 20 and 25mM in the aliquot 4 and 5 and L-proline was added @ 25 and 50mM in the aliquot 6 and 7, respectively. Diluted semen was filled in 0.25 ml French straws, sealed manually and equilibrated at 4°C for 2 h, cooled in LN2 vapour before being plunged into LN2 till further evaluation. Inclusion of L-proline and L-glutamine in the diluent significantly increased the percent live sperm, total motility, lipid peroxidation and maintained higher functional membrane and acrosomal integrity than the control group. In contrast, L-alanine decreased the percentage of total motility, fast progressive spermatozoa and increased the percentage of immotile spermatozoa. It can be concluded that 20mM L-glutamine and 25mM L-proline can be used as semen additive to freeze ram epididymal semen as they prevented cryo injuries to sperm and improved the pre-freeze and post-thaw semen characteristics.
