Dietary proteins exert a wide range of nutritional and biological functions. Apart from their nutritional roles as the source of amino acids for protein synthesis, they take part mainly in the regulation of food intake, blood pressure, bone metabolism, glucose and lipid metabolism, and immune functions. The interaction of dietary proteins with the gastrointestinal (GI) tract plays a chief role in determining the physiological properties of proteins. The enzymes protease and peptidase hydrolyze dietary protein to generate dipeptides, tripeptides, and amino acids in the lumen of the gastrointestinal tract. These products digested from dietary proteins are utilized in the small intestine by microbes. Moreover, the microbes also convert the macro and micronutrients from the diet into an enormous number of compounds that may have either beneficial or adverse effects on human health. The present review discusses the various impacts caused by both dietary plant and animal protein sources on microbiota in the GI tract.Keywords: Animal protein; Plant protein; Dietary proteins; Gut microbiota; Human health.

Phytic acid is the main storage form of P in grains and seeds. Cereals and grain legumes that are commonly used as poultry feed ingredients have similar phytate levels, approximating 0.25 percent of dry matter (Ravindran et al., 1995). There is not enough phytase activity in the digestive tract of chickens to digest phytate (Maenz and Classen, 1998). Phytate contributes to environmental pollution by reducing mineral and N bioavailability. The capacity of phytic acid to bind minerals reduces the utilization of P, Ca, Zn, Fe and N from plant ingredients by chickens (Sell et al., 2000). Phytate may form complexes with proteases, such as trypsin and pepsin in the gastrointestinal tract (Singh and Kricorian, 1982). These complexes may reduce the activity of digestive enzymes with a subsequent decrease in the digestibility of dietary proteins. It has been reported that microbial phytase improves the utilization of amino acids (Ravindran et al., 1999) and minerals in broiler chicks. The objective of the present study was to evaluate the effect of microbial phytase on the apparent digestibility of amino acids (AA) and some minerals in the diet of female broiler chickens.
