Biuretolytic Activity of Rumen Microorganisms as Influenced by the Levels of Dietary Biuret, Urea or Soybean Meal^{1, 2,}

Oklahoma Agricultural Experiment Station⁶ Stillwater 74074

Abstract

Studies were made to determine if the biuretolytic activity of rumen microorganisms was influenced by urea or soybean meal when either of these supplemental nitrogen sources were fed in combination with a biuret containing supplement. Neither supplemental nitrogen source significantly influenced the rate of biuret adaptation or the extent of in vitro hydrolysis. When biuret supplied 25% of the supplemental nitrogen, the biuretolytic activity was significantly less than that observed with the higher levels of biuret feeding.
