This paper summarizes factors which can affect the pH, volatile fatty acid concentration and proportions of the individual acids in the rumen liquor of dairy cattle. These factors are discussed in relation to experimental techniques.

New Zealand data on the proportions of the volatile fatty acids in the rumen liquor of sheep and cattle fed pasture are presented and discussed in relation to milk composition and the efficiency of milk secretion with dairy cattle.
