The experiment was performed with 210 weaned pigs to evaluate the effects of fructooligosacharides (FOS) and olaquindox supplementation to the diet on their performance from 21 to 63 days of age. Feed program was pre-starter, starter I and starter II diets, 0 to16, 17 to 30 and 31 to 42 days, respectively. The experimental design was a randomized blocks with six treatments and seven repetitions of five each: T1 - without FOS; T2 - with 0.1% FOS; T3 - with 0.2% FOS; T4 - with 0.3% FOS; T5 - with 0.5% FOS and T6 - without FOS and 25 ppm olaquindox. Fructooligosacarides supplementation to the diet did not affect the daily consumption and daily weight gain in any of the different periods tested. However, improved performance was observed in pigs treated with olaquindox in comparison to FOS treated pigs. In conclusion, FOS supplementation was inefficient in improving pigs performance, contrasting with results for aloquindox supplementation.
