Aflatoxins, particularly aflatoxin B1 (AFB1), are potent mycotoxins adversely affecting poultry performance, health, and product quality. Mitigation strategies are critical for poultry productivity. This study assessed the efficacy of Prosopis farcta biochar and Lactobacillus fermentum in mitigating AFB1-induced toxicity in quails, with a focus on performance, antioxidant status, and product quality. Two experiments were conducted with quails during growing (7–35 days) and laying (70–98 days) periods under five dietary treatments: Negative Control (basal diet), Positive Control (AFB1-contaminated diet), and AFB1 diets supplemented with Mycofix Plus, biochar, or biochar combined with L. fermentum. Growth performance, antioxidant status, meat and egg quality, and liver enzyme activity were evaluated. AFB1 significantly impaired performance, reduced meat and egg quality, and elevated oxidative stress and liver enzymes (P < 0.01). Supplementation with biochar, particularly in combination with L. fermentum, significantly alleviated these effects, improving body weight, glutathione peroxidase activity, and reducing malondialdehyde and liver enzyme levels (P < 0.01). Biochar and its combination with L. fermentum effectively mitigated aflatoxicosis in quails, enhancing health and productivity metrics. Integrating biochar and L. fermentum in poultry diets is a promising approach to managing mycotoxin challenges, improving economic and product quality outcomes in poultry systems.
