Effects of Ganoderma lucidum Powder on the Growth Performance, Immune Organ Weights, Cecal Microbiology, Serum Immunoglobulins, and Tibia Minerals of Broiler Chickens

Abstract

Ganoderma lucidum fungi are a rich source of several secondary metabolites, such as triterpenes, saponins, steroids, alkaloids, ganadic acid, and β-glucans. Although some Asian countries recommend their use in humans, little information existson alternatives to antibiotic growth promoters (AGP) in animals. Thus, this study aimed to demonstrate that G. lucidum powder (GLP) could positively respond to body weight gain, feed intake, and feed conversion ratio in broilers up to 32 days old. Moreover, GLP supplementation modulates intestinal microbiology by increasing the abundance of lactic acid bacteria without changing the concentrations of immunoglobulins; however, the AGP group had a decreased serum concentration of IgM. The higher level of GLP supplementation seemed to improve tibial mineralization; however, a broader mineral profile needs further investigation. These findings will contribute to the use of new natural products rich in beneficial chemical compounds as an alternative to AGPs in broiler production.
