Introduction
The use of antibiotics as growth promoter have several sides effects:
Chemical residues in the food chain
Development of resistant strain of pathogenic bacteria
Gut Health is important for the expression of the zootechnical performance of broilers.
The intestinal flora plays a key role in maintaining gut health.(Chahine and Bahna, 2010)

Discussion
• Increase in feed intake.• Increase in final body masse.• Improvement of feed conversion rate.• Decrease in mortality.
The effect of NSAB® Supplementation was more pronounce in case of use of economic feed.
