July, 1937 INSPECTION OF FEEDING STUFFS 



NUI'IBER OP SAMPLES FAILING TO COMPLY 



WITH THE LAW 



One hundred sixty five of the 400 brands analyzed . 

 failed to comply with the law in every respect, violat- 

 ing it on 195 counts. Nearl3r all of these violations, 

 however, are negligible if considered on. the basis 

 of the valueoof the feed to the purchaser. 



Eight brands were found deficient more than one 

 per cent in the most valuable constituent, protein. 

 These deficiencies were 2,66, 2,34, 2,11, 1.72, 1,27, 

 1,19, 1,18 and 1,14 per cent. Nine brands were de- 

 ficient more than one-half per cent but less than one 

 per cent. Eleven brands were deficient less than one- 

 half per cent. The 28 brands found deficient in ■ 

 protein is equivalent to 7,0 per cent of the brands 

 analyzed. 



Thirty-six brands or 9,0 per cent were deficient 

 in fat; 12 of these were deficient less than one- 

 fourth per cent. None of the other deficiencies was 

 more than 0,70 per cent except one which was 3,58 per 

 cent. 



Forty-four brands contained an excessive amount 

 of crude fiber. Eighty-seven brands were deficient 

 in carbohydrates. In the analysis of a feeding stuff, 

 the percentage of carbohydrates is usually determined 

 indirectly. It is found by subtracting the sum of 

 the percentages of protein, fat, moisture and ash frcm 

 100, It is obvious that an excess of protein and fat 

 over the manufacturer's guarantee decreases the per- 

 centage of carbohydrates found. Nearly all of this 

 year's carbohydrates deficiencies are due to the pro- 

 tein or fat or both exceeding the guarantee. 



In the tabulation of the. analytical data, pages 

 26 to 108 deficiencies of one-half per cent or more of 

 prot^im and of one-fourth per cent or more of fat are 

 underlined . 



In Table II is shown a summajTy of deficiency 

 figures over a twelve year period.
