HIGH GRADE COTTONSEED MEAL. 



Cottonseed meal is a by-product from the manufacture of 

 cottonseed oil. After the cotton has been taken from the seed 

 in the cotton gin, the remaining down or "linters" and the hard 

 black seed coats or hulls are removed by machinery. What 

 remains of the seed is cooked, and the oil expressed by high 

 pressure. The resulting cottonseed cake is ground into the 

 bright yellow cottonseed meal of commerce. Such a meal carries 

 from 40 to 50 per cent or even more protein. 



Sometimes the black hulls are ground with the cake and a dark 

 colored meal of very inferior feeding value is the result. Not 

 all dark colored meal is necessarily adulterated with hulls, but 

 strictly first-class fresh cottonseed meal is always bright and 

 yellow. 



The analyses of 132 samples of 18 different brands of high 

 grade and 8 samples of low grade cottonseed meal are here 

 reported. The high grade meal was all guaranteed to carry 43 

 per cent protein and 9 per cent fat. The protein ranged from 

 39.50 to 49.75 per cent, with an average of above 45 per cent. 



LOW GRADE COTTONSEED MEAL. 



In the fall of 1902 the feed market was in an unusual condition, 

 as feeding stuffs carrying high percentages of protein were very
