Total Yield of Milk Products — Concluded. 



Hay -\-Grain {Average, Periods I. and III.). 



The yield of milk was substantially the same on each ration. The total 

 solids showed an increase as a result of feeding the pumpkins, and this 

 was due evidently to an increase in the percentage of fat in the milk. 

 Attention has been called to the fact that the pumpkin seeds are rich in 

 fat. By referring to the average daily rations consumed (page 69) it may 

 be seen that the ration without pumpkins contained .68 pound daily of 

 digestible crude fat, and with the pumpkins 1.12 pounds, the excess of .44 

 pound of pure fat being derived from the pumpkin seeds. This additional 

 food fat evidently temporarily increased the fat in the milk. 



In so far as the results of a single experiment with two cows are concerned 

 it appears that 6 pounds of pumpkins fuUy replaced 1 pound of hay. On 

 the basis of digestible nutrients our calculations show that 4| pounds 

 of pumpkins with 84.8 per cent, of water replaced 1 pound of hay with 

 11.34 per cent, of water. It is quite possible that 25 pounds of pump- 

 kins would have replaced 5 pounds of hay with equal results. Because of 

 the rather wide variations in the moisture content of the fruit, one could 

 say only on the basis of results secured, that from 5 to 6 pounds of pump- 

 kins were equivalent to 1 pound of first-class cow hay.
