Abstract

SUMMARY: Assays using N and acetylene reduction showed that bacteria in the sheep rumen can fix atmospheric nitrogen. These bacteria are ingested when sheep are at pasture or provided with fresh, non-sterile, food. A permanent nitrogen-fixing microflora does not develop in the rumen. The addition of nitrogen-fixing bacteria to sheep rumina coupled with additional carbohydrate (10% molasses) in the feed increased the nitrogen-fixing capacity from 30 mg N to 800 mg N fixed/rumen/day.
