EXPERIMENT STATION BULLETINS. 359 



middlings and the remainder were "Standard" middlings or "Shorts." 

 In the majority of cases the samples were properly labelled although in a 

 few cases screenings were identified where the fact was not indicated 

 on the label. 



The percentage of protein found varied from 12.0 to 18.1 per cent and 

 the fat from 2.7 to G.5 per cent while the retail prices ranged from |22.50 

 to $35.00 per ton. 



WHEAT MIXED FEED. 



Eleven samples of wheat mixed feed were collected, 2 of which were 

 deficient in protein and five in fat. The percentage of protein was found 

 to vary from 13.1 to 1G.3 per cent and the fat from 3.7 to 5.4 per cent. 

 The retail prices quoted ranged from |24.00 to |31.00 per ton. The 

 feeds under this class are mixtures of wheat bran and middlings with 

 screenings and in many cases floor sweepings. All feeds under this 

 classification should be licensed before being placed on sale. 



WHEAT AND RYE MIDDLINGS. 



Two samples were collected, one of which was below guarantee in fat. 

 Both samples contained the same amount of fat while the protein 

 varied from 15.7 to 16.5 per cent. The retail prices quoted ranged from 

 $1.50 to 12.00 per cwt. 



RYE MIDDLINGS. 



Three samples of rye middlings were collected, only one of which was 

 guaranteed. The results show a wide variation in protein from 10.3 to 

 15.4 per cent and in fat from 1.5 to 3.1 per cent. The retail prices quoted 

 ranged from |14.50 to $28.00 per ton and it is interesting to note that 

 the sample having the lowest selling price contains the largest per- 

 centages of protein and fat. 



OAT MIDDLINGS. 



One sample of coarse oat middlings and two samples of fine oat 

 middlings were collected, all of which were manufactured by the same 

 company. The results found agree very well with an average analysis 

 for these products. 



BARLEY BRAN. 



Two samples of this class of feed were collected, both of which were 

 above guarantee, the result for protein being more than 100 per cent 

 above guarantee. The results as found agree very well with those given 

 in Henri's "Feeds and Feeding" for barley bran. 



CEREAL FOOD BY-PRODUCTS. 



Under this classification are included the by-products from the manu- 

 facture of breakfast foods. Twenty-five samples were collected, eighteen 

 of which were licensed and guaranteed. Five samples were below guaran- 

 tee in fat. As the feeds included in this class vary so widely in charac- 

 ter no comparison of the composition and retail prices can be made but 

 intending purchasers would do well to study the results given in the 

 following pages:
