Bloat in cattle

摘要

Abstract 1,2-dimethyl-5-nitroimidazole, given by rumen fistula, prevented bloat for six-eight days in three cows stall-fed red clover (Trifolium pratense L.). The treatment may have caused a slight, temporary reduction in food intake 24–48 hours after treatment. In a trial with grazing cows no effect on milk production was found. The protection from bloating appeared to be due to a reduction in protozoal numbers and the consequent reduction of fermentation rate in the rumen.
