Ruminants establish a symbiotic relationship with rumen microorganisms by which the animal provides nutrients and optimum environmental conditions for the fermentation of feeds, and microorganisms degrade fiber and synthesize microbial protein as an energy and protein supply for animal. Ruminal proteins degradation is affected by pH and predominant species of microbial population. A strong positive correlation was observed between dry matter intake (DMI) and microbial growth. The more carbohydrate digestion the more microbial protein synthesis occur. Fermentation energy is inversely related to microbial growth. Essential oil has domestic anti- microbial activity. Nitrogen compound or crude protein contain (CP) of many practical diets may be greater than the 11% required to support optimal microbial growth. Forage concentrate mixing preparation increase the efficiency of microbial protein synthesis than only forage preparation. The efficiency of microbial protein synthesis greater in forages containing saponin and tannins which reduce ruminal N degradability. As ruminant out flow rate increase microbial protein synthesis, it is supposed that the efficiency of microbial protein synthesis can be increased by about 20% if rumen outflow rate is increased from 0.02 to 0.08 /h. Microbial protein production will be a function of the availability of vitamins, microminerals and protein level in the diet of digestible organic matter. Microbial protein synthesis is dependent upon suitable N and carbohydrate sources. Even though trace minerals and vitamins are adequate for maximal microbial protein synthesis in many feeding conditions, inadequate trace minerals and vitamins, in some cases, could limit microbial protein synthesis
