The mean numbers of bacteria increased after each change in diet when increasing amounts of maize grain were substituted for maize stover. A surge in number of amylolytic bacteria always preceded an increase in lactate-utilizing bacteria, and with the final diet containing 71% grain and molasses the two groups tended to balance each other, which resulted in low lactic acid accumulation. The lactate utilizers thus played a key role in controlling the fermentation. Orderly shifts occurred among the predominating amylolytic and lactate-utilizing bacteria in response to the gradual decrease in ruminal pH as the amount of maize meal in the diet increased. Among the lactate utilizers, the succession began with acid-sensitive\n            <jats:italic>Veillonella</jats:italic>\n            and\n            <jats:italic>Selenomonas</jats:italic>\n            , which were superseded by more acid-tolerant\n            <jats:italic>Anaerovibrio</jats:italic>\n            and\n            <jats:italic>Propionibacterium</jats:italic>\n            .

The ecological succession of predominating genera was shown to be correlated significantly with ruminal pH and, more specifically, with the length of time as well as the extent to which the pH remained below a certain critical undefined value in the rumen, arbitrarily set at pH 6.00.\n          </jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381137046396281217","@type":"Researcher","foaf:name":[{"@value":"R.
