Effects of an Enterococcus faecium‐based probiotic on growth performance and resistance of Amazon ornamental fish Heros severus under short-term fasting

This study aimed to evaluate the deprivation and feeding frequency of H. severus fingerlings fed a diet supplemented with autochthonous probiotic E. faecium and challenged with the pathogen A. hydrophila. The experiment was carried out in 2 × 5 factorial, consisting of two food frequencies (two and four times a day) and four food deprivations with probiotic (P:7/0, P:6/1, P:5/2 and P:Alt) and one control (C:7/0). The deprivation factor, higher values of growth parameters were observed for fish from the treatments P:7/0 and P:6/1, as well greatest resistance of the A. hydrophila. Therefore, the use of probiotic E. faecium provided greater growth and resistance for H. severus.

Abstract

This study aimed to evaluate the deprivation and feeding frequency of H. severus fingerlings fed a diet supplemented with autochthonous probiotic E. faecium and challenged with the pathogen A. hydrophila. The experiment was carried out in 2 × 5 factorial, consisting of two food frequencies (two and four times a day) and four food deprivations with probiotic (P:7/0, P:6/1, P:5/2 and P:Alt) and one control (C:7/0). The deprivation factor, higher values of growth parameters were observed for fish from the treatments P:7/0 and P:6/1, as well greatest resistance of the A. hydrophila. Therefore, the use of probiotic E. faecium provided greater growth and resistance for H. severus.
