July 9,1917 Rate of Passage of Food Residues through Steers 63 



(4) Finer particles of feeds and finer ground feeds pass through the 

 animal more rapidly than the coarser ones. 



(5) An increase in the quantity of feed consumed causes an increase in 

 the rate of passage of feed residue. 



(6) The greater the capacity of the alimentary tract of the animal the 

 longer the time required for the passage of feed residues. 



(7) The determination of the rate of passage of feed residues through 

 steers by means of feces markers or color indicators is not feasible. 



(8) Doses of calcium carbonate and magnesium sulphate in quantities 

 of 60 or 120 gm. per steer daily exerted no appreciable influence on 

 digestive coefficients. 



(9) The average specific time required for the passage of the feed 

 residues on a normal ration probably varies between 72 and 84 hours, 



(10) The rate of passage of feed residue is influenced largely by the 

 nature of the ration and by the quantity, the importance of the two 

 influencing factors being in the order named.
