Summary

The rumen was found to be the main site of metabolism of biuret in sheep adapted to this compound. Some of the biuret which passed into the lower gut could be broken down there but this could account for the breakdown of less than 1 g/day when 15 g was fed. Biuret injected into the jugular vein or entering the bloodstream from the rumen or intestine was excreted unchanged in the urine. Sheep excreted 9–21% of biuret fed in a solid form and 37–39% when it was dosed as an aqueous solution. Sheep not adapted to biuret failed to retain any introduced into the rumen, duodenum or jugular vein.
