| ABSTRACT: It is noted that in recent years, modern poultry industry have undergone witnessed remarkable changes in production methods over the last 50 years. Therefore, meat and eggs are important to provide safe and quality protein sources in human nutrition worldwide. Interestingly, microbiota in the intestine has evolved together with the host, where intestinal health is also highly important for good production. Therefore, when gut health is compromised, digestion and nutrient absorption are negatively affected which, in turn, can have a detrimental effect on feed conversion leading to economic loss and a greater susceptibility to diseases. Thus, the microbial communities inhabiting in GIT of chickens are essential for the gut homeostasis, the host metabolism which affects the physiological and health status. Clearly, the dynamic equilibrium, composition and diversity of microbiota can be influenced by many environmental and management factors. However,, intestinal microbiota tends to increase most during the first weeks of life, and corresponding colonization patterns seem to differ between layer and meat-type chickens. On the other hand, gut microbiota and its relationship to health and productivity in either commercial broiler or egg chickens has been difficult to establish due to high variability among flocks, which derives from plenty of environmental, nutritional and host factors that influence the load of commensal and pathogenic microbes surrounding birds during their growth cycle in the farms. In this article we will focus on the importance of microbial homeostasis in GIT and the various factors that affect this equilibrium and the outcome of these interactions on intestinal health and productivity. | ||||
