Alfalfa saponins isolated by ethanol extraction and partial acid hydrolysis were intraruminally administered to sheep to investigate the biological activities and nutritional implications in ruminants. Mature wethers fitted with ruminal, duodenal and ileal cannulas were fed a concentrate or roughage diet formulated to be isonitrogenous and isoenergetic. Microbial fermentation and nutrient degradation in the rumen were reduced by saponins. Total protozoal count in the rumen was reduced 34 and 66… CONTINUE READING
