Turmeric nanofiber-encapsulated natural product formulation act as a phytogenic feed additiveA study in broilers on growth performance, biochemical indices of blood, and E-coli in cecum

摘要

A phytogenic feed additive (PFA) formulation was prepared with bioactive moleculescurcuminoids, gingerol, and carvacrol by encapsulating in nanofiber isolated from turmeric spent (turmeric nanofiber, TNF). This formulation was completely characterized by scanning electron microscope, ultra performance liquid chromatography, and gas chromatography and evaluated for its efficacy. PFA-encapsulated TNF (PFA@TNF) considerably increased mean body weight, decreased cholesterol level, mortality rate, and reduced Escherichia coli content of broilers than antibiotic growth promoter (AGP). The depth of crypts in the ileum of broilers was considerably reduced by the inclusion of PFA@TNF in diets compared with the AGP.
