Introduction: Short-chain fructooligosaccharides (scFOS) are oligosaccharides composed of fructose units with a terminal glucose, featuring ß linkages that are resistant to animal hydrolysis, resulting in their availability as selective substrates for the intestinal microbiota. scFOS have become highly valuable biotechnological compounds for the animal nutrition industry, aiming to modulate intestinal microbial populations to enhance intestinal health and productivity. Objective. Evaluate the use of increasing doses of scFOS supplementation on the productivity and morphological development of the intestine in broiler chickens. Methods: Two hundred one-day-old Ross AP chickens were homogenized and randomized following a completely random design with five repetitions of five treatments: D1: basal diet (BD) without scFOS inclusion, D2: BD + 700 g/ton of scFOS, D3: BD + 1050 g/ton of scFOS, D4: BD + 1400 g/ton of scFOS, and D5: BD + 1750 g/ton of scFOS. The experimental period lasted for 42 days, during which the animals received the treatments consistently. At the end of the experimental period, productive parameters were evaluated, and jejunal samples were taken to assess morphometric variables. Statistical analysis was conducted using generalized linear models and ANOVA with Tukey's mean comparison in the Rstudio program. Results and Discussion: Productive variables such as live weight and productivity index showed a significant linear effect (P<0.05) of the scFOS dose. The 1400 g/ton dose (D4) presenting the best productivity results. Regarding jejunal morphological development, treatment D5 significantly (P<0.05) exhibited the longest intestinal villi, while the villus-to-crypt ratio was mostly increased (P<0.05) by the 1050 g/ton dose (D3) of scFOS. Conclusion: The inclusion of scFOS in broiler chicken feed at doses ranging from 700 to 1750 g/ton improves productivity and morphological development, with a greater beneficial impact on productive outcomes at the 1400 g/ton dose.
