Abstract
This study was conducted to examine the effects of green tea polyphenols (GTP) and fructo-oligosaccharides (FOS) supplement on performance, counts of caecal microflora and its metabolites production. In female broiler chickens fed on semi-purified diets from 28 to 42 d of age, dietary green tea polyphenols (GTP) and fructo-oligosaccharides (FOS) significantly reduced mortality (p<0.05). Dietary GTP significantly decreased the total count of caecal microflora, each colonic population count and caecal flora metabolites contents when compared to other groups (p<0.05). Dietary FOS did not influence the total count of caecal flora but it selectively increased Bifidobacteri and Eubacteria counts (p<0.05) and decreased the count of other microflora and concentrations of caecal phenols and indole (p<0.0.5). These results suggest that GTP and FOS in semi-purified diets can decrease mortality and change the caecal colonic flora population, but GTP shows antibiotic-like effects of non-selectively decreasing all colonic flora and then metabolites, and FOS acts selectively by increasing profitable microflora and decreasing production of caecal microflora metabolites besides volatile fatty acids.

Summary
Would have a role in reducing environmental pollution and in improving the quality of animal products. Improvements in the quality of animal products by reduction of antibiotic residues and relief of environmental pollution by reduction of stink substance excretion have close relation with intestinal microflora. The purpose of our experiments is to investigate the effects of GTP and FOS supplementation on performance and counts and metabolites of caecal microflora in female broiler chickens fed on semi-purified diets. With an average body weight of 1,152±15 g 4,500 female commercial broilers (Arbor Acre) were selected at 28 d of age from 10,000 birds fed on commercial feed The selected birds were assigned randomly to control, GTP and FOS groups were housed in same semiopen henhouse which was disinfected adequately for a concrete floor, and supplied with wood shaving and an automatic feeder and water lines.
