DELLA ROSA, P et al. Aditivo orgánico en raciones para pacú (Piaractus mesopotamicus) en período reproductivo: Efecto sobre la recuperación de lesiones. Rev. vet. [online]. 2012, vol.23, n.2, pp.81-85. ISSN 1669-6840.

The aim of this study was to evaluate the recovery from injuries in broodstocks of pacu (Piaractus mesopotamicus) using commercial flavonoids added to the food before or after hormonal manipulations (induction of final oocyte maturation and spawning). Thirty nine adults of pacu were randomized into three groups according to the type of food offered: (G1) commercial diet, (G2) commercial diet until reproductive manipulations and then changing to commercial diet plus 2 g/kg of Flavoxin^®, and (G3) commercial diet supplemented with 2 g/kg of Flavoxin^® throughout the experimental period. The experiment lasted 69 days and during this period of time ovarian biopsies were performed to follow up gonadal maturation. Prior to hypophysation, the broodstocks showed good general condition. However, immediately after reproductive procedures, it was observed a high number of injuries in tegument and fins in all the fsh from G1 and G2, and low number of injuries in G3, which was statistically different (p^® added to the ration for P. mesopotamicus broodstocks prior to reproductive procedures allows a quick recovery from post-spawning injuries, thus improving health status.
