Grain Screenings. 



gains at the lowest cost, and proved buckwheat screenings to be 

 worth about the same as the meal mixture. It is seen that 866 

 pounds of meal gave the same gains as 852 pounds of buckwheat 

 screenings plus 32 pounds of roots plus 135 pounds of skim-milk. 

 At the above valuations of meal, roots, and skim-milk, buckwheat 

 screenings thus have a valuation of $27 . 60. 



(9) Comparing lots 1 and 5, it is seen that much smaller gains 

 were made where the complete elevator screenings and feed flour 

 constituted the total grain ration. Nevertheless, the low valuation 

 of the screenings shows that cheaper gains can be made, for a short 

 period, than with the meal mixture. It is seen that 866 pounds of 

 meal gave the same gains as 740 pounds of screenings, 250 pounds 

 of feed flour, 325 pounds of roots, and 1,350 pounds of skim-milk. 

 At the above valuations for meal, roots, and skim-milk, a mixture 

 of elevator screenings, 3 parts; and feed flour, 1 part, is worth $18.40 

 per ton. 



Finishing Period. — Owing to the limited quantities of elevator 

 (Screenings and by-products, the experimental period was only con- 

 ducted for forty-two days. At the end of this time all six lots were 

 placed on a finishing period preparatory to marketing. All the 

 lots were given the standard meal mixture, similar to that given to 

 lot 1 of the experimental period. All the lots were given roots and 

 skim-milk except lot 6
