Mushroom Supplementation in Promoting Health and Performance of Poultry: Review

Abstract

This review paper aims to update and discuss the latest data available with respect to the effects of mushrooms in promoting the health and performance of broiler and layer chickens. Most studies proved that different preparations of mushrooms from diverse mushroom species improved feed utilization efficiency, growth rate, egg production, and quality traits. Mushroom supplementation decreased the count of pathogenic bacteria ( Clostridium spp., Coliforms, and E.coli and increased that of beneficial ones ( Lactobacillus spp. and Bifidobacterium) in both broiler and layer chickens. Inclusion of different preparations (powders, extracts, leftovers, etc.) of mushrooms resulted in lower cholesterol and other lipid metabolites in poultry meat and eggs. Some studies reported no significant effect of mushroom on the performance of broiler and layer chickens, however, it is concluded that mushrooms, in various forms, could be included in poultry diets without any harmful effect on their health. Further research works are also suggested to investigate the opportunities for making mushrooms part of the compound poultry feed ingredients in countries like Ethiopia.

Benefits of Mushroom-Based Supplements on Growth Performance, Immunocompetence, and Meat Quality in Poultry

“…The combinations of Shiitake, reishi, and cordyceps improved broilers’ body weight and boosted their immune response [ 15 , 16 ]. Shiitake inclusion in the layers’ diet was reported to improve egg production by reducing egg yolk cholesterol [ 17 ]. Likewise, the immunomodulatory effect of Cordyceps militaris was reported by Cheng et al [ 18 ].…”
