244 The Feeding of Animals 



turing process has been so improved that from forty 

 to forty -five gallons of oil are now obtained from a 

 ton of seed, giving a correspondingly smaller amount 

 of cake. Chemists are well aware that cottonseed 

 meal at the present time is less rich in oil than was 

 the case a few years ago. 



When we learn that no less than 1,500,000 tons of 

 cottonseed are worked annually at oil mills, which in- 

 volves the production of about 600,000 tons of meal, 

 we realize the importance of this by-product feeding 

 stuff, and the future possibilities are seen in the fact 

 that only about one -third of the seed now grown finds 

 its way to the oil mills. The composition of the cotton 

 oil by-products may properly be stated in this con-

These figures represent the composition of the several 

 materials when the separations are fairly complete. 

 Cottonseed products are sometimes sold, however, in 

 a more or less mixed condition. There has been found 

 in the market undecorticated cottonseed meal, or the 

 meal with all the hulls ground in without removal 

 from the seed. Practically all the meal found in the 

 markets now is the decorticated, or that free from 

 hull. This should be light yellow in color and have a 

 slightly nutty flavor. It should show few or no black
