 found a ready sale in our market. 



So far as known cocoanut meal is sold only by one dealer in 

 Massachusetts and at a price which renders it an economical 

 concentrate. It contains slightly less protein and decidedly more 

 fat than gluten feed and should equal it in feeding value. 



The two brands of peanut cake meal reported are of excep- 

 tionally high quality and are without doubt obtained from the 

 " peanut kernel alone after the extraction of the oil. As agriculture 

 becomes more diversified in the South, the peanut will become 

 more of a staple crop and greater quantities of peanut cake will 

 find their way into the market. The more common practice, 

 however, will probably be to crush the shell together with the nut; 

 the resulting mixture will contain more fiber and have less feeding 

 value than the samples reported. 



Only one brand of gluten meal, the Diamond, 

 Gluten Meal. manufactured by the Corn Products Refining 

 Page 9 Co., was found. All of the samples collected 



exceeded their protein guarantee of 40 per cent. 

 At the price asked and on account of its high protein and low 

 fiber content, it can be considered a most excellent source of pro- 

 tein in the dairy ration.

All of the samples of gluten feed collected were

 Page 10 guarantees. Gluten feed "as put out by most 



manufacturers at the present time differs ma- 

 terially from the product as originally sold in that the material 

 dissolved out of the corn by soaking in the first step of preparing 

 the grain for the separation of starch, is now recovered by evap- 

 orating the solution in vacuum evaporators and the resulting 

 solid residue added to the feed. This condensed steep water 

 increases the apparent acidity of the feed as well as its protein 

 content. The increase in protein is believed to be due largely 

 to soluble protein-like substances which have been dissolved out 

 of the seed by the steep water and not to true protein. 



Gluten feed usually sells at a price which makes it an economi- 

 cal protein concentrate for dairy purposes. Tt is best u.«;ed as a
