Compositional analysis of resurrection bush plant (Myrothamnus flabellifolius) and its potential mode of action in broilers
Résumé
Antibiotic feed additives are added to broiler diets at subtherapeutic dosages to boost feed conversion, accelerate growth and improve meat yield. However antibiotic growth promoters have fostered the emergence and spread of antibiotic resistant genes which has led to their ban and has raised public concern regarding the dissemination of antibiotic resistant pathogens and their implications for food safety and human health. Myrothamnus flabellifolius plant native to Southern Africa known to survive extreme desiccation has rich bioactive compounds and carbohydrate profile that can potentially affect broiler performance, health and meat quality. In this narrative review the literature search was designed to encompass parameters related to M. flabellifolius plant nutritional and phytochemical composition and how the mode of action of the compounds affects broiler growth performance, health and meat quality. M. flabellifolius contains carbohydrate trehalose, raffinose, stachyose and sucrose which act as prebiotics and energy sources when included in broiler diets as a feed additive. Phytochemical composition of resurrection bush plant, which is rich in phenolic, flavonoid and other bioactive compounds improves broiler gut health, immunity, reduces oxidative stress and improves broiler meat quality and shelf life. Understanding the preliminary chemical and phytochemical composition of M. flabellifolius and its perceived mode of action and relating that to broiler performance and meat quality is essential and form the basis for the formulation of diets that enhance broiler welfare and product safety. Future research should prioritize in vivo investigations to gain more comprehensive insights into the interactions among these dietary components and identify the optimal combinations for broiler feeding strategies.
