that the feed delivered must comply with the New Hampshire Commercial 

 Feed Law. If the feed is not registered ; if the protein, fat, and crude fiber 

 are not guaranteed; and if the ingredients of which the feed is composed 

 are not plainly stated on the bag or on a tag attached thereto, the purchaser 

 is not protected by the law. He has no recourse under the commercial feed 

 law if the feed he purchases is of inferior quality. If the buyer fails to 

 assure himself that the legal requirements have been met, he accepts the 

 feedingstuffs at his own risk. 



The cost of a feedingstuffs inspection includes the drawing and 

 analysis of samples, and the publication and distribution of the annual 

 bulletin. The funds from which these costs are paid are accumulated from 

 the license fee which the manufacturer is required to pay annually on each 

 brand registered for sale in the state. A calculation based on the known 

 costs of the inspection and the estimated retail value of the feedingstuffs 

 sold annually, shows that the cost of the inspection is only a fraction of a 

 cent per 100-pound bag. 



TERMS USED IN REPORTING ANALYSIS 



The terms used in reporting the chemical analysis of a feedingstuff 

 as required by law, are briefly defined as follows : PROTEIN is a collective 

 term for a considerable group of compounds, all of which contain nitrogen. 

 Ingredients high in protein are usually more expensive than the other in- 

 gredients, therefore, protein is one of the most important nutrients de- 

 termining the commercial value of a feedingstuflf. The nutritional value of 

 the proteins varies widely; therefore, a feedingstuff should contain protein 

 from several sources to insure inclusion of all essential types. FAT is 

 separated from the other components of a feedingstuff by extracting the 

 moisture-free sample with anhydrous ether. In such ingredients as the 

 cereals, the seed-meals, and animal products, the extract is nearly pure fat. 

 A few ingredients such as alfalfa meal contain some other soluble material 

 which is not fat. When sulphur is present, the "ether extract" or "fat 

 found" is much too high, since sulphur is soluble in anhydrous ether. 

 CRUDE FIBER is composed of cellulose and related compounds. Since 

 crude fibre has little feeding value, the law requires that the maximum 

 fiber be guaranteed rather than the minimum, as in protein and fat. 



There are times when it is desirable to determine the moisture or water 

 present in a feed. Any material in contact with the air will absorb or re- 

 lease some moisture depending upon the humidity and the kind of material. 

 Since feeds are in contact with the air and since the moisture content 

 varies somewhat with the moisture of the surroundings, it is the usual 

 custom to report the analysis of a feed on the basis as it is used, rather 

 than on a perfectly dry basis. The ash or total mineral matter content is 

 of value at times and is obtained by burning a sample of the feed until all 

 of the carbon is removed and only the minerals remain. The nitrogen-free 

 extract contains the more soluble carbohydrates such as sugars and cer- 

 tain simple cellulose materials. The term carbohydrates includes the nitro- 

 gen-free extract plus the crude fiber. The nitrogen-free extract and 

 carbohydrate content of a feed is determined by calculation after the 

 analysis for certain other constituents. The usual analysis of a feed may
