Abstract

Polioencephalomalacia (PEM) in ruminants has traditionally been attributed to a thiamin deficiency. Recent studies have demonstrated that PEM lesions may result from excess total sulfur intake and the resulting ruminal H2S generation. The objectives of this trial were to examine the effect of varying water sulfate (SO4) concentrations on the patterns and magnitudes of hydrogen sulfide (H2S) generation and health of feedlot cattle.
