Aloe vera na criopreservação do sêmen de tambaqui (Colossoma macropomum)
This study aimed to evaluate the extract of Aloe vera (AV) associated or not with 10% Dimethylsulfoxide (DMSO) in cryopreservation of tambaqui semen. For the formation of the pools (n= 14), 30 males were hormonally induced twice. Each pool had the objective motility, curvilinear velocity, straight-line velocity, average path velocity and morphology analyzed before and after cryopreservation of semen. The means for cryopreservation were constituted of Powder Coconut Water-104 diluent added DMSO and/or AV (5 or 10%). After cryopreservation, motility, velocities and morphology were reduced significantly when compared to fresh semen. For sperm motility the best treatment was that using only DMSO (20,86±8,31) and DMSO + 5% AV (15.71±9.77). For the velocities, the worse treatment was DMSO+10% AV. Treatment with only the addition of DMSO had a significantly higher effect than others on percentage of morphologically normal sperm. The mean correlation found was between motilityand the rate of morphologically normal sperm (r = 0.687). In conclusion, the addition of AV does not provide greater protection for spermatozoa during cryopreservation.
