We will present in an abridged form those that have given the best

Good and Poor Rations 



The New Jersey Experimental Station made the following test 

 between a good ration and a poor one. 



SUMMARY OF TEST 



Result of the Test 



Four cows were included in the test which continued for two months. 

 The milk from each cow was weighed daily and the per cent of butter-

SUMMARY OF TEST 



"This summary shows that 687.5 pounds or 34.1 per cent more 

 milk, and 31.47 pounds, or 38.9 per cent more fat were produced from 

 the good rations than from the poor rations, an actual gain in pro-
