SEMEN QUALITY OF PIRACANJUBA FISH (<i>BRYCON ORBIGNYANUS</i>) AFTER CRYOPRESERVATION
Abstract
One experiment was conducted in Environment Center of Energy Company of Minas Gerais-Brazil and in the Physiology and Pharmacology Laboratory of Veterinary Medicine Department of Lavras University (UFLA) in order to evaluate the effect of two extenders (Glucose 5% and Coconut water) in the freezing semen of Piracanjuba (Brycon orbignyanus). In the present study were used Sodium bicarbonate 0.5 and 1,0% and destilated water to activate sperm motility. An factorial 2 X 3 was used for test the effect of two extenders for freezing semen and three sperm motility activator in post-freezing semen. The sperm motility post-freezing was 60% in Coconut water and was observed significative effect (P<0.01) for the motility activators used. The duration of sperm motility there was no significative difference (P>0.01) in the two extenders used but was higher when Sodium bicarbonate activator was used. The Coconut water used as extender of freezing semen and Sodium bicarbonate used as sperm motility activator post-freezing semen increase and extend, respectively the sperm motility in Piracanjuba freezing semen.Downloads
