Two lots of low grade cottonseed meal were found which sold for 

 substantially the same price as the high grade product. While these 

 meals were properly guaranteed as to their content of protein and 

 fat, their feeding value is not much over one-half that of choice meal. 

 This inferiority is due to a liberal admixture of hulls which seriously 

 decreases digestibility as well as protein and fat content. 



Because of the exceptionally high prices now prevailing for cotton- 

 seed meal, buyers cannot be too careful in purchasing. They should 

 carefully scrutinize the guarantee and make sure that 41 per cent 

 protein is guaranteed for choice, 38.5 per cent for prime and 36 per 

 cent for good meal. It is safer, when purchasing in car lots, to ask 

 that a sample be submitted to the experiment station as a check on 

 the guarantee. (For special instructions for sampling cottonseed 

 meal see circular 25 issued by the station.) 



The linseed meals analyzed were all of good quality. The demand 

 for this product is evidently so great that the manufacturers are able 

 to secure a price somewhat above that secured for other high grade 

 concentrates. It is an excellent source of protein for the dairy 

 ration and it is to be regretted that its cost prevents its general use 

 by Massachusetts dairymen. 



* It should be borne in mind that this is an average figure for the year just past and 

 that at present cottonseed meal is bringing a mucli higher price.
