Efeito do núcleo homeopático homeopatila 100® na eficiência produtiva em alevinos revertidos de tilápia do nilo (Oreochromis niloticus) Effect of core homeopathic homeopatila 100® in productive efficiency of fingerlings reverted from nile tilapia (Oreochromis niloticus)

It was researched the effect of Core Homeopathic Homeopatila 100® on the integrity branchial histological, weight, final length, survival, feed conversion and apparent index hepatossomatic in fingerlings from Nile tilapia ( Oreochromis niloticus). We used in the control treatment (T1) with 20mL/ kg water-alcohol solution (alcohol 30 GL) and three treatments with 20mL/kg (T2), 40mL/kg (T3) e 60mL/kg (T4) of core homeopathic Homeopatila 100® in fingerlings male reversed, with initial weight and initial length the 1,05 ± 0,32g and 4,15 ± 0,42cm respectively. It was distributed a total of 832 fingerlings in 16 polyethylene water tanks with individual capacity of 2000 liters, contends 1000 liters each one, where they ha remained during 61 days. At the end of experiment, was not observed statistic difference between the different treatments in histological changes examined in gills: epithelial lifting, hyperplasia, telangectasy and lamellar fusion. The fingerlings which received 40mL/kg of Homeopatila 100® (T3) showed a higher rate of survival and also lower rate than the other hepatossomatic the fingerlings in control group (T1).
