Abstract:
BACKGROUND: The cryopreservation protocol that has been developed exclusively for the preservation of the sperm of the species different.
Objective:
this study was to evaluate the effect of the association of 10% DMSO with trehalose, raffinose, sucrose and lactose concentrations on the sperm cells of Piaractus mesopotamicus.
Materials And Methods:
Sperms were collected from the animals through abdominal massage. The samples were diluted in the Beltsville Thawing Solution without different concentrations of other sugars (test conditions). Sixty days after the cryopreservation, cell movement analysis was performed using CASA.
Results:
The results revealed that the parameters for total motility and motility period were superior when 100mM raffinose (P <0.05). The lateral displacement of the head was observed to be improved was 100mM lactose, 150mM sucrose and 150mM raffinose (P <0.05) as compared to treatment wherein lactose (0mM) was omitted.
Conclusion:
the results of our study indicated that the ideal parameters for cryopreservation, were obtained when the cryopreservation fluid contained 100mM raffinose in association with DMSO.
