Oral administration of Gum Arabic: effects on haematological parameters and oxidative stress markers in Mugil cephalus

The aim of this research was to investigate the effects of the oral administration of Gum Arabic on haematological and some oxidative stress markers in Mugil cephalus. For this purpose ۶۰ mullet caught in Faro Lake (Italy), were acclimatized and fed with commercial diet for ۲۰ days prior to the start of experiment, which lasted ۱۵ days. After acclimatization, fish were randomly divided into two equal groups: control group was fed with commercial pellets. Haematological profile on whole blood and sera was assessed, reactive oxygen metabolites (d-ROMs), antioxidant barrier (OXY-ads) and thiol-antioxidant barrier (SHp) were immediately assessed by means of a UV spectrophotometer. Two-way repeated data analysis (ANOVA) showed significant changes only on Thrombocyte Count (TC). In the experimental group an increase in OXY-ads and SHp levels and a significant decrease of d-ROMs were observed after administration of GA.
