Description
Changes in immune response to several rumen bacterial species were investigated in grazing cattle. The results revealed immune response variation in cattle from the first and second grazing seasons. Agglutination titers in sera to Streptococcus bovis and Butyrivibrio fibrisolvens increased after 30 days of grazing. Those of S. bovis remained at a higt level until grazing was competed, while titers of B. fibrisolvens were maximum after 45 days and gradually decreased. Changes in agglutinating titers to both bacterial species varied greatly in cattle of the first grazing season. Titers of Ruminococcus albus were similar to the above two species, whereas those of Succinivibrio dextrinosolvens were relatively stable. Thus changes in agglutinating antibodies after grazing seem to reflect changes in the number of rumen microflora and, to a lesser degree, the feed available during grazing.
