One hundred and forty-four Avin broilers (1 d of age) were randomly divided into six groups with three replicates of eight birds each to study on the effects of different oligosaccharides on performance and availability of nutrients in broilers. The control group (Group I)was fed with corn-soybean meal as basal diet and the trial groups (Group II, III, IV, V and VI) were fed with basal diet plus 0.1% Manoligosaccharides(MOS), 0.3% Soybean-Oligosaccha-rides(SBOS), 0.3% Fructo-oligosaccharides(FOS), 0.3% α-Glucooligosaccharides(α -GOS) and 50 mg centre dot L~(-1) Chlortetracy-cline(CTC) respectively. The results showed that the supplementation of oligosaccharides slightly improved daily gain and feed intake. SBOS suppiementation improved but MOS andα-GOS significantly decreased availability of energy Oligosaccharides supplementation improved availability of energy phosphorus calcium magnesium and iron and significantly increased cholesterol content of fecal and did not affect on availability of protein and cholesterol contents in serum and muscle. Availability of phosphorus of broilers fed with FOS was much higher than that with α-GOS SBOS supplementation remarkably increased availability of iron.
