Abstract
SILAGE-MAKING is becoming more and more general in many countries, and it is necessary to pay more attention to its quality because the quality of milk and milk products suffers from a bad silage. The quality control of silage is therefore important. The simplest and quickest method of control is the determination of pH. In general, it can be said that when the pH of silage is between 3 and 4 (the AIV method) the decomposition processes (formation of carbon dioxide, ammonia and volatile acids) are slight in the silage and its quality is good. When the pH rises, the quality of the silage is lowered. Formation of butyric acid is then common, and ammonia is formed freely. Determination of these substances is of first importance in the control laboratories.
