Abstract

Abstract Two separate lots of 12 lambs were randomly assigned to 3 treatment groups of 4 sheep each. Groups received rations of grain alone, grain + methionine hydroxy analog or grain + hay with either urea or soybean oil meal as the primary nitrogen source. After a ration adjustment period of 3 weeks, rumen samples were obtained on 3 successive weeks. Protozoa concentration was significantly higher in the grain + methionine hydroxy analog-fed sheep (P<0.01) over the grain-alone group, but significantly lower than the grain + hay-fed sheep (urea P<0.05-SBOM P<0.01).
