amount of crude fiber, are made. An extensive study of low 

 grade compared with high grade cottonseed meal has been made, 

 and is reported on pages 71-76 beyond. !More and more the 

 jobbers of feeding stuffs are looking to the Station for its 

 opinion on new feeds, and the result has been that during the 

 past year an increasing number of samples have come from the 

 large handlers of feeding stuffs, who wished to learn the chem- 

 ical analysis of new goods before deciding whether they would 

 handle them or not. In this way the consumer is getting a pro- 

 tection that a fev\" years ago would have seemed impossible. 



COTTONSEED MEAL (ANALYSES PAGES 55 AND 56.) 



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 machinen.-. 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 protein. 



The shippers of cottonseed meal for the m.ost part guarantee 

 43 per cent protein and 9 per cent fat. According to the classifi- 

 cation of the Cotton Seed Crushers' Association, "■prime" cotton- 

 seed meal from the Gulf States must carry not less than 7^ per 

 cent ammonia. As 8 per cent ammonia is equivalent to only 

 41 . 19 per cent protein, it is evident that the minimiim guarantee 

 is placed higher by the shippers than the association calls for in 

 prime meal. Hence a meal that carries 41 per cent protein is 

 "prime" in the trade sense, but is below the guarantee usually 

 placed upon cottonseed meal sold in ]\Iaine. 



The Xational Cotton Seed Products Company are putting a 

 guarantee of 41 per cent protein and 8.50 per cent fat on their 

 Indian brand cottonseed meal and F. W. Erode are at least 

 occasionally putting a guarantee of 41 per cent protein and 7 per 

 cent fat on their Owl brand. Both of these m.eals are on the 

 average as good as any sold in the State and it would probably 

 be much better if the other companies doing business in the State 

 were to lower guarantees for protein to the standard of the 

 Cotton Seed Crushers' Association.
