Abstract

Data were compiled from 4,143 cattle on byproduct feeding experiments. Incidence of polioencephalomalacia was small (0.14%) in diets containing 0.46% or less sulfur (S). Incidences of polioencephalomalacia increased when cattle were fed diets above 0.46% S and especially above 0.56%. Phosphoric acid successfully replaced sulfuric acid in ethanol fermentation, but the amount and cost of phosphoric acid likely limit the economic feasibility of its use.
