Utilização de extrato hidroalcoolico de casca de jabuticaba na alimentação de fêmeas betas azuis

Abstract

The inclusion of jaboticaba extract in the diet of female Bettas splendens was evaluated in the performance of the color and enzymatic parameters. Fifty ornamental fish with an average initial weight of 1.49 ± 0.546 g were used, being distributed in a completely randomized design, with five treatments. The levels of addition of jabuticaba hydroalcoholic extract (EHJ) were: 0.00; 12.5; 25; 50 and 100% ml. The fish were fed five times during 21 days at the respective times: 08:00; 10:00 am; 12:00 pm; 14:00; 16:00 hours. There was a significant difference in relation to feed conversion, however in the growth indices, being they weight gain, length gain, height gain and consumption did not present any significant difference. There was no increase in intensity in relation to luminosity, chromaticity a * (shades of green and red) and chromaticity b * (shades of blue and yellow). The biochemical parameters of CAT, ALT, AST and alkaline phosphatase did not differ with the inclusion of EHJ. However, regarding non-specific protease activity, amylase, lipase and SOD showed a difference with the variation of the diet. It is concluded that the inclusion of the hydroalcoholic extract of the jabuticaba extract is not efficient for the use of nutritional additive for blue female Bettas splendens.
