feeds, cotton seed meals and oil meals and a relative 

 decrease in the number of mixed dairy feeds. The quality 

 of the feeding-stuffs shows a marked improvement and 

 the deficiencies in guaranteed analysis are less frequent this 

 year. The largest percentage of deficiencies in analysis are 

 found among the compounded feeds, oil meals, calf meals 

 and poultry feeds. Last year over five per cent, of the 

 samples analyzed were deficient in both protein and fat 

 while this year only three per cent, show such deficiencies. 

 A larger number than last year of the higher analysis and 

 better quality cotton seed meals were found. 



SLIDING SCALE OR DOUBLE GUARANTEE. 



The law definitely provides that the manufacturer shall 

 state only the minimum percentage of protein, fat and 

 carbohydrates upon the guarantee. The object of this is to 

 prevent the purchaser from being misled by a double 

 guarantee. For example without this provision in the law 

 when a guarantee shows 30 per cent, to 45 per cent, protein 

 an analysis of 30 per cent, is all that is necessary to meet 

 the guarantee, although the guarantee may lead the pur- 

 chaser to believe that he may get close to 45 per cent., when 

 as a matter of fact he is more apt to get 30 per cent, or 

 even less. The last year has shown some improvement in 

 this regard. In 1921 out of 246 samples analyzed 10 sam- 

 ples or 4 per cent, had a double guarantee while in 1922 

 out of 360 samples only 10 or less than 3 per cent, had a 

 double guarantee. In publishing the guaranteed analysis 

 the maximum figures have been used. 



CLASSIFICATION OF FEEDING-STUFFS 

 ANALYZED. 



In classifying the feeding-stuffs the class names under 

 which they have been sold have been used. Table Number 

 1 shows the number of feeding-stuffs in each class, the
