are usually more expensive than the other ingredients, making pro- 

 tein the most important nutrient for consideration in determining 

 the commercial value of a feedingstuff. The nutritional value of the 

 proteins varies widely; therefore, a feedingstuff should contain pro- 

 tein 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 ether-soluble material which is not fat. When 

 urea is present the figure for the percentage of fat found may be 

 high as much as two-tenths per cent, due to the slight solubility of 

 urea in anhydrous ether. When sulphur is present, the percentage 

 of fat found is much too high, since sulphur is readily soluble in 

 anhydrous ether. 



Fiber is composed of cellulose and related compounds. Since 

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

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



This bulletin is concerned with the enforcement of the feeding- 

 stuffs law. It is not within its scope to make recommendations re- 

 garding the use of commercial feedingstuffs. The Department of 

 Dairy Husbandry and the Department of Poultry Husbandry are 

 continuously studying feeding problems. The following publications 

 of these departments are free to residents of New Hampshire. Ad- 

 dress your request to Mail Service, University of New Hampshire,

HOW COST OF INSPECTION AFFECTS PRICE 



The cost of a feedingstuff inspection includes the drawing and 

 the analysis of the samples, and the publication and mailing of the 

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