	abstract = {The fate of mineral solutions when drenched was assessed in cows  
slaughtered after drenching using a dye visible in gut contents.  Seven 
groups of 10 cows were drenched with water or solutions of magnesium oxide,  
magnesium chloride, magnesium sulphate, sodium chloride, sodium  
bicarbonate or zinc oxide in Trial 1.  Frequency of closure was higher (P<0.05)  
for sodium bicarbonate (60\%) than for magnesium oxide or magnesium  
chloride (10 to 20\%).  Five cows drenched with water alone showed bypass of  
the rumen.  In Trial 2 four groups of 6 or 7 cows were drenched with water or  
solutions containing selenium.  Hydromin or copper sulphate.  Frequency of  
closure was higher (P<0.05) for copper sulphate (70\%) than for water or  
selenium (0\%).  The results suggest that bypass of the rumen in response to  
drenching may contribute to apparent failures of bloat drenches, particularly  
when certain minerals are added to the drench.
