Comparing the first and eighth periods, in which food 

 and conditions were alike, we find an increase in the cost 

 per quart of 3-10 of 1 cent and a decrease in quantity of 

 10 per cent. In the 80 days of the test, the daily yield 

 of milk decreased 10 per cent. How much of this natu- 

 ral decrease took place in each feeding period, we cannot 

 say, being an unknown factor I have left it out, neverthe- 

 less, its influence has been felt, and in considering the 

 above figures a small allowance should be made in favor 

 of the second ration, and this allowance should be in- 

 creased for each of the following periods until in the 

 eighth it amounts to 10 per cent. We did not have, nor 

 could we get, any corn fodder fit to use, at the time we 

 made the above tests. If we could have got it, we should 

 have used it. To determine the exact relative value of 

 the different foods as compared with English hay, it 

 would be necessary to limit the ration during one period 

 to nothing but hay and then with the results of that 

 period, as a basis, compare other foods. This we did not 

 care to do, as the cows in the test, being used to grain, 

 would have fallen off in their milk to a point, from which 

 it would be hard work to get them back. In the table 

 and in the computations which follow, we have used but 

 one and two decimal places to save time, and the results 

 while not mathematically exact, are relatively correct. 

 The cows came out of the test in good condition. 



From the foregoing, it is safe to assert that when good 

 English hay is worth $20.00 per ton, that mowed oats are 

 worth "S^IS.OO, and meadow hay 'flO.OO also that mangels 

 at 16 cents per bushel can be fed profitably, and that the 

 average cow when fed fair rations of grain, will not use 

 over 16 lbs. of hay per day to the best advantage.
