Control of Aflatoxin Residues in Broiler Chicken Using Saccharomyces cerevisiae Fortified Ration

Abstract

The current research was designed to examine the protective effect of probiotic-fortified ration against aflatoxin B1 (AFB1) toxicity and its residual level in broilers' edible tissues. Sensitive high-performance liquid chromatography coupled with a fluorescence detector (HPLC-FLD) was used for measuring the toxin. Ninety, one-day-old Cobb chicks were allocated into three equal groups (n=30) with three replicates per group. The first control group (G1) was fed a balanced basal diet only and the second group (G2) received AFB1 (2 mg/kg basal diet), while the third group (G3) received a combination of AFB1 (2 mg/kg basal diet) with Saccharomyces cerevisiae (SC; 1.5 g/Kg basal diet). Experimental birds were monitored for 6 weeks, their growth performance was then compared. AFB1 residue was assessed in the meat and liver sample. AFB1 resulted in a significant (P<0.05) reduction of growth performance parameters such as body weight and carcass yield in comparison to the control and SC supplemented groups. Moreover, AFB1 residue significantly (P<0.05) diminished in SC fortified group when compared with the AFB1 group. In conclusion, probiotics such as Saccharomyces cerevisiae could be considered as a potential feed additive and a growth promoter. Besides, its role in controlling AFB1 residue in the edible tissues of boiler chicken.
