Management, follow-up and monitoring of TMR in dairy and fattening cattle enterprises affect the health and production of animals significantly. The procedure and formulation applied during the preparation of TMR can either affect the production and health of the animal favorably or the mistakes made during the preparation of TMR can cause metabolic disorders in animals and thus these disorders can lead to production losses.

TMR Audit is based on analyzing and reporting critical control points such as mixing time, forage/concentrate ratio, compatibility of the mixer used, particle size of the forage, distribution of coarse and fine particles inside TMR and distribution time of the TMR formulation which is prepared in the dairy or fattening enterprises with "Penn State Shaker Box" which consists of 5 different sieves with different sieve pore radii.
