In this series of experiments the data show conflicting results. All 

 the cows gave more milk when fed the turnip ration, and they also ate 

 that ration much more readily than they did the entire dry-roughage 

 one. The two cows that were fed the ration in the order wet-dry-wet 

 gave milk of a higher fat content on the wet ration, while those fed 

 in the dry-wet-dry order gave the higher percentage of fat when the 

 dry ration alone was fed. None of the other constituents of the milk 

 were appreciably affected, and in the case of the fat content the data 

 are so conflicting that they seem to have been caused by some factor 

 other than the ration. 



DRY VERSUS WET BEET PULP 



Two cows were used in this trial, one being fed wet, dry, and wet beet 

 pulp in successive periods, with a transition period after each change in 

 ration, and the ration of the second cow being just the reverse. While 

 being fed dry beet pulp each cow received 10 pounds daily. The wet 

 ration consisted of 40 pounds of the wet beet pulp, or 10 pounds of the
