EVALUACIÓN DE TRES DILUTORES EN LA CRIOPRESERVACIÓN DE SEMEN DE ALPACA ( Vicugna pacos ) EN PELETS

The objective of this study was to evaluate three dilutors: AndroMed®, Triladyl® and Tris base in the cryopreservation of alpaca semen in pellets, it’s was electroejaculation collected. 15 ejaculates from 7 male alpacas were used; cryopreservation was evaluated by motility and sperm motility patterns (VCL, ALH); highly significant differences (p <0,01) in total sperm motility were found in cooled semen, Tris base and Triladyl® were higher. sperm curvilinear velocity (VCL) in Triladyl® was higher relative to other diluters. In the thawed semen statistical differences (p <0,05) was found in the VCL, being superior to others Triladyl®. The thawed sperm motility of the pellets is still low, lack refine protocols that allow us to have similar sperm parameters that are taken into cooling.
