Lead (Pb) is one of the most common environmental pollutants commonly used in industrial areas and is toxic to humans and animals. The aim of this study was to investigate the effects of beta-glucan supplementation on the diet of Japanese quails exposed to Pb toxicity on digestibility, total coliform, and total lactic acid bacteria counts. In the study, 112 Japanese quails at the age of 5 weeks were randomly divided into 4 groups of 7 quails each with 4 replicates. The quails were fed with feeds containing 1) control, 2) 100 mg/kg Pb, 3) 100 mg/kg beta-glucan, 4) 100 mg/kg Pb and 100 mg/kg beta-glucan. While the Pb supplementation statistically significantly reduced the numbers of coliform bacteria (P<0.01), the effect of beta-glucan was found statistically insignificant (P>0.05). The supplementation of beta-glucan to the diet, dry matter and ether extract digestibility and cecum lactic acid bacteria count did not significantly change in quails with lead toxicity (P>0.05). While crude protein digestibility did not change in the control and beta-glucan groups (P>0.05), a decrease was observed in the Pb group (P<0.001). In conclusion, no negative effects of beta-glucan supplementation on nutrient digestibility and lactic acid bacteria were observed. Lead decreased the numbers of coliform bacteria and crude protein digestibility. Beta-glucan supplementation was not found to have an effect on lead toxicity in terms of parameters examined.
