An update review on the use of agro-industrial byproducts on carcass and meat quality of broiler chickens

The use of agro-industrial byproducts as feed ingredients or supplements has become increasingly common in recent years. This is beneficial not only because it can reduce broiler chickens’ reliance on conventional feed ingredients or synthetic supplements, but it can also help the environment. The dietary inclusion of agro-industrial byproducts may also help to increase carcass yield and reduce the abdominal fat content of broiler chickens. Furthermore, agro-industrial byproducts can help improve the physical, chemical, and sensory properties of broiler breast and thigh meats. The use of agro-industrial byproducts is frequently associated with improved protein digestibility in chickens, which has an impact on increasing protein accretion and carcass yield. Some bioactive compounds found in agro-industrial byproducts, such as oligosaccharides and phenolic compounds, appear to be responsible for the improvement in physical, chemical, and sensory properties of broiler chicken meat. However, nutrient content may vary in agro-industrial byproducts, so broiler farmers must be cautious when using them as feed ingredients in broiler chicken feed. Moreover, some conditions (such as high crude fibre content, poor protein quality, and the presence of anti-nutritional factors) may restrict the use of agro-industrial byproducts in broiler chicken diets because they may reduce nutrient digestibility and availability, disrupt amino acid balance, impair antioxidant status, lower muscle protein deposition and carcass yield, and reduce protein content in broiler meats. This review article provides an updated overview of the use of agro-industrial byproducts as feed ingredients or supplements, as well as their effects on the carcass and meat quality of broiler chickens.
