Resumo
Flaxseed oil is recognized as the plant source richest in α-linolenic acid, whereas clove leaf essential oil has a strong antioxidant capacity.The objective of this study was to determine the in vitro antioxidant capacity of diets containing a combination of flaxseed oil (FO) and clove leaf essential oil (CLEO), as well as to use zebrafish (Danio rerio) to assess theireffect on the animalsgrowth. Fifty days after hatching, a total of 420 male specimens (0.29 ± 0.04 g)weredivided into seven groups for each diet and fed for 55 daysto be used, with the diets being: control, absent FO and CLEO; 3% FO + 0.5% CLEO; 3% FO + 1% CLEO; 6% FO + 0.5% CLEO; 6% FO + 1% CLEO; 9% FO + 0.5% CLEO and 9% FO + 1% CLEO. Antioxidant activity was determined through DPPH (2,2-diphenyl-1-picrylhydrazyl) tests, showing interaction effect between factors (FO x CLEO, p <0.05); the diets containing 1% combined with 3, 6 or 9%of FOpresented meanshigher than those of the0.5%diets. No mortality was observed during the experiment. For final weight and weight gain, there was no interaction effect (p> 0.05), only isolated effect for FO, with the fish fed 6 and 9% diets having the best results. Final total length and specific growth rates showed interaction effect (p <0.05). As for specific growth rates, the best response was that of the diet with 6% FO and 0.5% CLEO. Final length showed increase with FO levels, even when there was association with0.5 or 1% of CLEO. Therefore, combined use of9% of FL with 0.5% of CLEO is recommended for zebrafish.(AU)
