YEAST AND VINEGAR GRAINS. 



Only two samples of this class of feed were taken both of which were 

 equal to guarantee. This feed is sometimes confused with brewers' 

 grains and by some feed manufacturers is used in place of brewers' 

 grains when the latter is declared. In mixed feeds containing a number 

 of ingredients it is very difficult to distinguish between yeast or vinegar 

 grains and brewers' grains. The yeast and vinegar grains are inferior 

 to brewers' grains as they have less protein and considerably more fiber. 



Malt grains. 



This feed is quite similar to brewers' grains and can well be substi- 

 tuted for them in mixed rations. It was olferod for sale at an average 

 price of |5o.75 per ton. The five samples taken were in no way deficient. 



• 



GLUTEN PEED, 



Samples were drawn from eigliteen lots of gluten feed ranging in 

 l)rice from lf!'5(> to $70. Five sain{)les were below .guarantee in protein. 

 None were deficient in fat or contained an excess of crude fiber. 



HOMINY FEED. 



Eleven samples of hominy feed were taken representing the product 

 of six manufacturers. All samples conformed closely to guarantee except 

 one which was low in protein. Tliis feed retailed at prices between 

 153.50 and 160.00 per ton. 

 • 



CORN GERM MEAL. 



But six lots of corn germ meal were sampled, all the product of one 

 concern. With the exception of one sampie wliich was deficient in 

 protein, all were well above the guarantees for ]»rotein and fat. Corn 

 germ meal is the residue from corn germs after tlie corn oil has been 

 extracted. It has a feeding value about equal to wheat middlings. 

 The average price of the shipments sampled was 102 per ton. 



CORN FEED MEAL. 



The analyses of 13 samples of corn feed meal are shown in the tables. 

 Of this number three were below guarantee in both protein and fat 

 and one in fat only. The average percentage of fat found in these four 

 samples was 3.5 while the average guarantee was 7.8 per cent. Such a 

 variation between the guaranteed and fouud results indicates gross care- 

 lessness on the part of the manufacturers. The retail price varied from 

 12.30 per cwt. for a lot sampled late in the fall of 1918 to .|72.00 per ton 

 for a shipment found in June, 1919. 



ANIMAL BY-rRODITT. 



In this classification are included digester tankage of all grades, meat 

 scraps and meal and poultry bone. Four of the 27 samples collected 

 were below guarantee in protein ; practically all were above the guarantee 

 for fat and but one contained an excess of ci'ude fiber.
