Potential and challenge assessment of tannin extracts from black tea in male rabbits fed contaminated diet by Mycotoxins

Abstract The focus of this research was to investigate how tannin extract from black tea influenced the hematological and histopathological evaluations of male rabbits fed a mycotoxin-contaminated feed, including 17 ppb aflatoxin, 5 ppb ochratoxin and 2 ppb fumonisin. A total of 28 local male rabbits were allocated into four groups, the first of which was a control group. The second was fed a Mycotoxin-contaminated meal. The third was given a Mycotoxin feeding with tannin extracts (125mg/mL per head) administered orally, while the fourth was fed a Mycotoxin contaminated diet with tannin extracts (250 mg/mL per head) given orally. The findings revealed that tannin extracts seemed to have a significant positive impact on haematological results, particularly RBCs and WBCs, throughout the period; however, the 250 mg/mL dose showed no significant differences in Hb levels. Nonetheless, as compared to the Mycotoxin group, the histopathological sections of tannin extract demonstrated a reduction in the toxicity of the Mycotoxin diet on the liver and kidney tissues; conversely, the tissue sections of the control animals showed no abnormalities. In male rabbits fed contaminated Mycotoxin diets, tannin extract from black tea was found to have a favourable impact on hematological activities and vital organs such as the liver and kidney.
