Variation in Numbers and Mass of Ciliate Protozoa in the Rumens of Sheep Fed Chaffed Alfalfa (Medicago sativa)

摘要

Masses and numbers of rumen ciliate protozoa were markedly different in individual sheep fed chaffed alfalfa hay under different feeding regimens. Studies on the ciliate contribution to specific aspects of rumen fermentation should take into account the size of members of each genus in individual animals as well as the numbers present.
