A.S. Series 67-19
Several sources of nonorotein nitrogen, including urea and nitrate, are known to be utilized by rumen microbes for protein synthesis after conversion to a common intermediate, ammonia. This has led to the speculation that the presence of urea may result in a decrease in the utilization of nitrate or its reduction products, thereby increasing the apparent toxicity of nitrate.
The experiments reported herein were ccnducted to determine if measurable urea-nitrate interrelationahios exist in sheep under feedlot conditions, and the extent of nitrogen utilization from urea and nitrate by sheep fed rations containing otherwise suboptimum quantities of crude protein.
