Abstract   

The study was designed to evaluate the effects of probiotics (Bacillus subtilis) to enhance immunity, antioxidation, digestive enzymes activity and hematological profile of Shaoxing duck. A population of 200 laying ducks (160 days old) was divided into two groups each further divided in five replications. The control (G1) were fed on basal diet and (G2) with B. subtilis 1×108 cfu/kg in addition of basal diet for thirty five days. The results showed that, ducks were treated with probiotics (B. subtilis), their serum IL-2 increased and IL-10 decreased (P<0.05). The concentrations of IgG, IgA and sIgA were observed significantly higher in (G2) as compared to (G1). Treatment group (G2), showed significantly improvement in (SOD), T-AOC and ASAFR activity in serum and liver. However, digestive enzymes amylase and trypsin activity also improved (P<0.05) in (G2). The blood chemistry analysis showed significant decrease in FT3 and no other significant change observed in hematological profile as compared to (G1). In conclusion, application of B. subtilis (1×108 cfu/kg) may be beneficial to improve antioxidation response, supportive in innate immunity and digestibility of fowls (Shaoxing duck).
