Ochratoxin A (OTA) is a mycotoxin notably produced by Aspergillus and Penicillium spp. Bacillus subtilis fermentation extract (BSFE) contains specific enzymes which hydrolyse OTA. This study evaluated the efficiency of BSFE in ameliorating the immunotoxic and nephrotoxic effects of OTA in broiler chickens.

Multi-class and multi-residue analyses are very complex procedures because of the physico-chemical properties of veterinary drug residues and other contaminants. The purpose of the study was to develop an analytical method for the sensitive determination of 69 analytes in bovine milk by liquid chromatography electrospray ionisation–tandem mass spectrometry.

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.
