effect of rumex sc on ruminal fermentation, blood metabolites and performance of lactating dairy cow

this study investigated the effect of rumex sc (commercial product which includes of saccharomyces cervisiae, saponin and essential oils) on rumen fermentation, blood glucose, urea, milk yield and milk composition. animals were offered a basal diet containing alfalfa hay (15.5%), corn silage (24%), beet pulp (7%) and concentrate (53.5%). additionally, rumex sc was included in the experimental diet at a rate of 5 g/day/cow. sampling of milk, ruminal liquid and blood was conducted for determination of milk composition, fermentation parameters and blood metabolites. milk yield was significantly increased for the experimental group when compared to the control group (p
