This study was conducted to show the effect of Aspergillus awamori (AA), fructooligosaccharide (FOS), and combined Aspergillus
awamori and fructooligosaccharide (AA+ FOS) on growth, digestibility, blood parameters, and expression of some growth-related
genes. A total of 60 broiler chicks at the age of 15 d were divided into a control group (𝑛 = 15) and 3 treatment groups.The control
group was fed a basal diet, and the treatment groups were fed basal diets supplemented with 0.05% AA, 0.05% FOS, and combined
of 0.05% AA and 0.05% FOS. Results from measurement of growth performance and digestibility revealed a significant increase
in the body weight gain with improved feed conversion rate in the experimental groups. Interestingly, dry matter digestibility
(DMD) and crude protein utilization (CPU) were improved. In addition, plasma total cholesterol and low density lipoproteincholesterol
(LDL-C)were decreased,while plasma high density lipoprotein-cholesterol (HDL-C) was increased by feeding AA, FOS,
andAA+ FOS. Expressions of growth hormone secretagogue receptor (GHSR), insulin-like growth factor 1 (IGF-1), and insulin-like
growth factor 1 receptor (IGF1R) were increased in experimental groups. In conclusion, the supplementation of either Aspergillus
awamori or fructooligosaccharide or both improves digestibility and growth performance probably by promoting skeletal muscle
protein metabolism.
