The study investigated the effect of fermented purple sweet potato flour (PSPF) on intestinal and physiological health of broilers. A 189-day-old broiler chicks were divided into T0 (diet based on corn and soybean meal), T1 (diet containing 15% unfermented PSPF), and T2 (diet containing 15% fermented PSPF). Samples collection and measurement were conducted at day 35. The T2 chicks had greater (p < 0.05) weight gain than T1, but did not differ from T0. Feed conversion ratio (FCR) was better (p < 0.05) in T2 than in T1. The mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) were higher (P < 0.05) in T2 than in T0 and T1 groups. Haemoglobin tended (p = 0.08) to be lower in in T2 than in T0 and T1 groups. Heterophils were higher (p = 0.05) in T2 than in T0 and T1 groups. Total cholesterol and high-density lipoprotein (HDL) were higher (p < 0.05) in T0 than in T1. Low-density lipoprotein (LDL) tended (p = 0.06) to be lower in T1 than that in T0. Total protein and globulin were higher (p < 0.05) in T0 than that in T1 and T2. Lactic acid bacteria (LAB) to coliform ratio in the ileum was higher (p < 0.05) in T2 than in T0. LAB counts tended (p = 0.08) to be greater in T2 than in other chickens. T1 tended (p = 0.09) to have a smaller number of lactose negative Enterobacteriaceae (LNE) in caecum as compared to that of T0 chicks. T2 tended (p = 0.09) to have a lower crypt depth than T0. In conclusion, feeding fermented purple sweet potato flour contributes for the better growth, feed conversion, immune defence, bacterial population and morphology of the small intestine.
