fed oil meal and milk. Lot 11 received gronnd oats and milk, 

 the hulls of the oats having been sieved from the ground grain 

 in the second and third trials. Lot III received corn meal with 

 about 10 per cent, of ground flax seed additional. A summary 

 of the trials appears in the following table:

 meals — Iowa Station. 



Commenting on the experiments, Curtiss writes: "The results 

 of all the investigations made at this Station strongly indicate that 

 it is not only unnecessary but poor economy and poor practice in 

 feeding to use a highly nitrogenous product like oil meal in com- 

 bination with separator skim milk. The practice has neither 

 logical reason nor scientific theory for its support; and in the corn- 

 belt states, with their surplus of corn and oats, there is no neces- 

 sity for the purcliase of a high-priced nitrogenous product to be 

 used in yupplementing the skim-milk ration," (199) 



520. Gravity versus separator skim milk. — Thirty-two calves 

 less than 10 weeks old, weighing on an average 130 pounds, were 

 fed from 30 to 50 days on three Danish estates under the direction 

 of the Copenhagen (Denmark) Station. ^ The calves received 

 about 20 pounds of separator skim milk daily per head in addi- 

 tion to oats, peanut meal, corn, barley or hay, singly or combined.
