Protective effects of dietary Kefir against aflatoxin B1-induced hepatotoxicity in Nile tilapia fish, .

The effect of dietary Kefir supplementation on the biometric, biochemical, and histological parameters of Nile tilapia () exposed to aflatoxin B1 (AFB1, 200 µg/kg diet) contamination was studied. The yeasts were dominant in Kefir followed by lactic and acetic acid bacteria. The Kefir showed relatively interesting antioxidant potential in the DPPH• (IC = 0.
