The outstanding importance of the vast member of microorganisms in the rumen to the nutritional physiology of the ruminant makes it imperative that the factors influencing the numbers and types of these organism be thoroughly understood. A knowledge of when these ruminal fluctuations occur and their causes, whether it be due to external environment or dietary change, would be of significant value in the preparation of rations which could stimulate the ruminal flora to their maximum efficiency and in turn receive maximum feed efficiency from the animal. The specific objectives of this project are as follows: to make periodic checks of the in vitro rumen temperature, to make periodic determination of in vitro rumen, to graphically illustrate how these determinations were affected by any of the various factors, to attempt to grow culturally, rumen microorganisms to determine any periodic concentration change which may occur.
