Rumen acidosis
Subacute ruminal acidosis is a herd problem more than a cow problem: intake swings, milk fat drops, manure loosens and sore feet follow months later. The papers under this heading cover how low rumen pH comes about, how it is diagnosed, and how fibre, starch, buffers and bunk management are used to keep it in check.
27 papers are filed under this heading. Main sources: Western Dairy Digest, Western Canadian Dairy Seminar: Advances in Dairy Technology, Intermountain Nutrition Conference.
