A study was carried out in Sirohi buck. Semen collection was made biweekly from each buck
with the help of artificial vagina. A total of 12 ejaculates were collected from two bucks (six ejaculates from each buck).
Freshly collected semen was pooled and later evaluated. The pooled semen sample was extended with standard glycerolated
egg yolk tris extender and later subjected to a process of cryopreservation. The motion and kinematic characteristics of
spermatozoa were studied during freez-thawing process.is
