Feeding Experiments. 



23 



Deductions— Aa will, be seen the above results do not indicate 

 any particular increase in the palatability of the meal ration due 

 to the addition of molasses meal. One hundred pounds of the mix- 

 ture were removed from the cows and credited to them. Even with 

 the lower production in Period 2, and after having valued molasses 

 meal at $34.50, the cost to produce with the screenings ration is 

 appreciably lower. 



Keeping in view the limitations of this test, the following deduct- 

 ion is possible: A mixture of equal parts of Caldwell's molasses 

 meal and pulverized complete screenings replaced about the same 

 quantity of the regular meal mixture for milk production, and is 

 worth about $25 per ton. 



Comparing these results with those of Experiment No. 4, it 

 would appear that in spite of the unpalatability of screenings, due 

 to* the presence of black seeds, the complete screenings fed as above 

 acquire a value of $27.50 per ton.
