This work was conducted to evaluate the effect of probiotic (BIOMIN) ® on lead acetate absorption and it is toxic action on certain physiological and biochemical parameters: body weight gain, Hb concentration, PCV%, serum total protein and serum lead level in chicks. One-day-old forty Ross broiler chicks were used. The probiotic was used in recommended dose (1.5g/kg diet). Lead acetate was used in two doses; full dose of 320 mg/kg diet and half dose of 160 mg/kg diet. The results show that probiotic significantly (P≤0.05) decreased serum lead level, enhanced body weight gain, while it has no direct significant effect on serum total protein, Hb concentration, and PCV%. On the other hand, lead acetate alone (in both doses) was caused sever anemia, depression in the level of both Hb concentration and PCV%, while half dose (160 mg) of lead acetate was caused no effect on both body weight gain and serum total protein, but death of some chicks, and decreased serum total protein were occurred with full dose of lead acetate.
