In poultry nutrition, most attention is given to protein products, due to the importance of protein as a
major constituent of the biologically active compounds in the body. It also assists in the synthesis of body
tissue, for that renovation and growth of the body. Furthermore, protein exists in form of enzymes and
hormones which play important roles in the physiology of any living organism. Broilers have high dietary
protein requirements, so identification of the optimum protein concentration in broiler diets, for either
maximizing broiler performance or profit, requires more knowledge about birds' requirements for
protein and amino acids and their effects on the birds' growth performance and development. It also
requires knowledge about the protein sources available that can be used in poultry diets. The broad aim
of this review is to highlight the importance of some of the available high-quality specialized protein
products of both animal and plant origins which can be explored for feeding broiler chickens. Minimization
of the concentration of anti-nutritional factors (ANFs) and supplementation with immunologically
active compounds are the main focus of gut health-promoting broiler diets. These diet characteristics are
influenced by feed ingredient composition and feed processing. The general hypothesis is that these
protein products are highly digestible and devoid of or contain less ANFs. Feeding these products to
broiler chicks, especially at an earlier age, can assist early gut development and digestive physiology, and
improve broiler growth performance and immunity.
