Is a high lactic acid content in the silage a problem?

Lactic acid per se is not a problem but silages with particularly high lactic acid levels may have undergone an extended fermentation leading to high levels of total acids in the silage and a high buffering capacity.  It is the buffering capacity and the total acid content that should be considered, not the lactic acid content alone.  Silages with a higher proportion of lactic acid in the total acids tend to have a lower buffering capacity.

Recognising the type of fermentation that has occurred and balancing the diet properly will prevent any problems with these silages.
