Analysis of vitality and biochemical parameters in freeze-thawed seminal plasma of rams
The current study aimed to examine the percentage changes of viability sperm
and the activity of the enzymes LDH, ALP, GOT / AST, GPT / ALT in the sperm
plasma of Lacaune rams, before and after cryopreservation. For this purpose,
five rams were examined, and two ejaculates were obtained from each ram.
Ejaculates are collected by the method of artificial vagina, during the
insemination campaign. All ejaculates were diluted with a 6AG extender and
frozen by the Cassou?s sequin method. Sperm viability was determined by
eosin and nigrosine smears, and enzyme activity was examined
spectrophotometrically. As a result, the percentage of vital sperm after
cryopreservation decreased by 15% (P ? 0.001). The freezing and thawing
process also reduced the activity of the enzymes LDH, ALP, GOT / AST and GPT
/ ALP. In conclusion, the observed enzymes, in relation to sperm vitality,
could be used as indicators to optimize the protocols for cryopreservation
of ram?s sperm.
