ingstuff should contain protein from several sources to insure inclusion of 

 all essential types. 



Fat is separated from the other components of a feedingstuff by ex- 

 tracting 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 ma- 

 terial which is not fat. 



Moisture is present in all feedingstuffs. The amount varies somewhat 

 with weather and storage conditions. The water content of a feedingstuff 

 should be kept as low as possible to prevent spoilage. 



Ash is the mineral residue remaining after the organic matter has been 

 completely removed by burning. It contains such essential constituents as 

 calcium, magnesium, phosphorus and sulphur, as well as some inert ma- 

 terial of no nutritive value. 



Fiber is composed of cellulose and related compounds. Since crude fiber 

 has little feeding value, the law requires that the maximum fiber be guar- 

 anteed rather than the minimum as in protein and fat. 



Nitrogen free extract includes the carbohydrates which are more readily 

 digestible, such as starch and sugars. Nitrogen free extract is not usually 

 determined directly by analysis but is found by subtracting the sum of the 

 percentages of protein, fat, fiber, moisture and ash from one hundred per 

 cent. 



HOW COST OF INSPECTION AFFECTS PRICE 



The cost of a feedingstuffs inspection includes the drawing and the 

 analysis of the samples, and the publication and mailing of the annual bulle- 

 tin. The State Legislature provides an annual appropriation to meet this 

 cost and is remunerated by the feed manufacturers from license fees col- 

 lected by the State Department of Agriculture. Since this cost is finally paid 

 by the purchaser, he is interested in the effect of these costs on the retail 

 price per ton. The 16th census of the United States Department of Commerce 

 under the heading, specified farm expenditures, 1939, reports the retail value 

 of feeds for domestic animals and poultry sold in New Hampshire in that 

 year as $7,619,245. A calculation based on this valuation and the known costs 

 of the inspection shows the cost to the purchaser is less than four cents per 

 ton of feed, a fraction of a cent per one hundred pound bag. 



SAMPLES FAILING TO COMPLY WITH THE LAW 



Of the 461 brands analyzed, 28 brands oi* 6.1 per cent, were below guar- 

 antee in protein. Twelve of these were less than one-half per cent below
