COMMEKCIAL FEEDING STUFFS. 



CORN AND OAT FEEDS. 



Under this heading have been classified not only the products 

 labeled "corn and oat feed" but also chop feed, provender, feeds 

 bearing names that would indicate that they were composed of corn 

 and oats, and feeds which a microscopical examination has shown 

 to be composed chiefly of corn and oats. 



The average composition of corn and oats, and of ground corn and 

 oat feeds, as they appear on the market, is given in the following 

 table:" 



TABLE 18. Average percentage composition of corn and oat feeds. 

 [Compiled.] 



On the whole it may be said that a large number of the corn and 

 oat feeds and the samples labeled ground corn and oats reported in 

 Table 19 are unsatisfactory in their composition, adulteration with 

 hulls being indicated in many cases by the high ash, crude fiber, and 

 pentosan content and the small amount of starch present. Even 

 when no adulteration with hulls is indicated a number of the samples 

 show by their low protein and fat content that they are made up of 

 inferior grades of corn and oats. In some cases a wheat product, 

 such as bran, middlings, or red-dog flour, has been added, probably 

 for the purpose of raising the protein content. 



It is unnecessary to mention all the individual cases of apparent 

 adulteration in Table 19. A comparison of the analyses with the 

 average given in Table 18 and an inspection of the microscopical 

 examination show at once what samples are to be rejected. 



The "chop feeds" and "provenders" are open to the same criti- 

 cism as the "corn and oat feeds," but perhaps to a somewhat less 

 extent. Some evidently contain an excess of hulls, while others 

 are made from cereals of poor quality. Only a very few of them 

 are entirely above suspicion. From the amount of weed seed found 

 in some of these samples it is evident that screenings were used in 

 their preparation or that they were made from very inferior grains. 



Samples Nos. 1604, 1933, and 1958 have just about the composi- 

 tion that would be expected in a mixture of corn and oats without 

 an excess of hulls.
