The study was conducted to investigate the effect of dietary inclusion of cassava yeast as a probiotic source on growth performance, ileum morphology and carcass characteristic. Two hundred and forty 1-day old broiler chicks of both sexes were used for 42-days. The chicks were randomly allocated to 24 pens containing 10 chicks each with 6 replicates and assigned to receive one of 4 dietary treatments (1. Control, 2. S. cerevisae 1x10(6) organisms/kg, 3. S. cerevisiae 1x10(7) organisms/kg, 4. S. cerevisiae 1x10(8) organisms/kg) in a completely randomized design. There was no significant difference in the feed intake starter period, feed conversion ratio, average daily gain and dressing percentage. Significant differences were observed in feed intake finisher period, tight percentage and villus height. The results of the present experiment showed that dietary inclusion of cassava yeast as a probiotic to broiler seems to have minimal influence on broiler performance. Also, further research is required to determine the dose and form of the probiotic used.
