No. 6. DEPARTMENT OF AGRICULTURE. 481 



The ivory nut meal, referred to, is an interestin<? product as it is 

 the ground cuttings from the ivory nut from which buttons are made. 

 This material has a bony, liard structure, but when i)ulverize<l and 

 ground into a fine meal, it possesses some feeding value and a portion 

 of it is digestible. It has the following composition: l*rotein 4.50%, 

 fat 0.85%, and fiber 8.30%. The law does not prohibit the sale of 

 this particular material, and, therefore, we can make no objection to 

 its use although in every feed on which it is used as an ingredient, 

 it must be stated on the sacks or on the tags that it forms a part 

 of the feed. 



The cocoa shell ftieal has been used for about a year as an ingredient 

 in mixed feeds and is the ground shells left from the bean from which 

 cocoa is made. This product has the following average analysis: 

 Protein 16%, fat 3.50%, fiber 12-14%. A study is now being made 

 of the value as a feed of garbage tankage, and this may be placed 

 on the market as an ingredient for mixed feeds later, although the 

 process of manufacture has not developed far enough to warrant its 

 being offered for sale. Other by-products of interest which some peo- 

 ple are ti'ying to mix in feeding stuffs is peat, which is sometimes 

 called humus. This material contains a large proportion of sand and 

 insoluble matter and the Department has refused to permit the sale 

 of any feed in the State which contains this product as an ingredi- 

 ent. 



The Department has received splendid support and co-operation in 

 the work being done along this line, from the dealers and feed manu- 

 facturers of the State, and also of the United States. A few years ago 

 an organization was formed, called the Association of Feed Control 

 OflScials of the United States, made up of the officials of each State 

 which were in charge of the enforcement of the feeding stuffs laws. 

 Our Department has been represented at these meetings by the Secre- 

 'tary of Agriculture, the Chief Chemist and the writer. Much valu- 

 able information has been secured as a result of these meetings, as 

 special attention is paid to the study and discussion of the various 

 by-products being used and definitions have been adopted for prac- 

 tically every product known to the trade. The definitions which, up 

 to date, have been adopted are as follows and will be included in the 

 report, but I will not take up your time in reading them now. 



MEAL is the clean, sound, ground product of the entire grain cereal 

 or seed which it purports to represent. 



CHOP. is a ground or chopped feed composed of one or more dif- 

 ferent cereals or by-products thereof. If it bears a name descriptive 

 of the kind of cereals, it must be made exclusively of the entire grains 

 of those cereals. 



SCREENINGS are the smaller imperfect grains, weed seeds and 

 other foreign majterial having feeding value, separated in cleaning 

 the grain.
