REVIEW OF THE ANALYTICAL WORK. 



To economize space and save expense, the preceding tables simply give the 

 average analyses of samples collected and not the analyses of individual 

 samples, as formerly. The statement of certified ingredients is also omitted. 

 Data omitted are on file at the experiment station and will be furnished, upon 

 application, to those interested. 



Cottonseed Meal. — The greater part of the cottonseed meal sold was 

 guaranteed to contain only 36 per cent, protein, and the average analysis of 

 all samples collected showed less protein and fat and more fiber than for the 

 preceding year. It is hoped that when conditions again become normal 

 cottonseed crushers will see the wisdom of mixing fewer hulls with the meal. 

 Formerly cottonseed meal contained 43 or more per cent, protein and about 

 7 per cent, fiber, while now the fiber content varies between 10 and 15 per 

 cent., — a condition which decreases the feeding value of the meal. 



Cottonseed Feed. — Twenty samples of this product were collected. 

 Cottonseed feed is the mill-run hulls and meal ground together, or a mixture 

 of cottonseed meal and delinted hulls (erroneously called cottonseed bran) 

 mixed together in about the proportion of mill run, while in cottonseed meal 

 a considerable proportion of the hulls has been removed. The addition of 

 all of the hulls seriously decreases the feeding value of the mixture. 



Linseed Oil Meal. — During the past season linseed meal sold at a price 

 which compared favorably with cottonseed meal. Linseed meal, while con- 

 taining slightly less total protein, is fully equal in feeding value to the cotton- 

 seed meal now being sold. One sample manufactured by the American 

 Milling Company contained screenings and was so guaranteed. 



Miscellaneous Oil Cakes. — Corn germ oil cake meal is the ground corn 

 germ cake from which the oil has been partially extracted. A considerable 

 difference will be noted in the analyses of the different brands, probably due 

 to a greater admixture of the starchy part of the corn kernel in the samples 

 containing the smaller amount of protein. The corn germ meal may be de- 

 rived from either cornstarch factories or hominy mills. It has a high feeding 

 value. 



Cocoanut oil cake meal is derived from the meat of the cocoanut after partial 

 extraction of the oil, and approximates gluten feed in feeding value. Cocoa- 

 nut meal has the reputation of easily turning rancid. If it does not contain 

 an excessive amount of water and is stored in a cool dry place, there will 

 probably be no diflSculty in keeping the product for a reasonable time.
