It will be seen that 100 pounds of low-grade cottonseed meal contained 

 about 30 per cent, less digestible organic matter than the high-grade 

 material. The addition of hulls to cottonseed meal, even in small amounts, 

 lessens its feeding value in two ways: first, it decreases its protein content; 

 second, it impairs its digestibility. Since the quahty of the meal sold in 

 Massachusetts is gradually growing poorer, consumers have a right to 

 know just where this decreasing feeding value is going to stop. Manu- 

 facturers claim that it is due largely to improved processes in the ex- 

 traction of the cottonseed oil. 



(3) Cottonseed Feed Meal. 



Cottonseed feed meal is either a mixture of cottonseed meal and crude 

 hulls or of cottonseed meal and cottonseed hull bran. When the mixture 

 consists of cottonseed meal and hulls it is usually derived from the Sea 

 Island cottonseed, to which no lint adheres, and is theoretically the entire 

 seed (both kernel and hulls) ground together after the extraction of 

 the oil. 



Cottonseed hull bran is the cotton hull from wliich the hnt has been re- 

 moved by a special process. In the preparation of cottonseed for the 

 manufacture of oil the lint is not entirely removed. A number of mills
