COMMERCIAL FEEDING STUFFS. 



OAT FEEDS. 



The average composition of ground whole oats, oat hulls, and oat 

 straw, as given by Winton and Jenkins, is as follows : 



TABLE 16. Average percentage composition of ground whole oats, oat hulls, and oat 



straw. 



[Compiled.] 



Considering the samples of oat feeds reported in Table 17 as a whole 

 it is at once evident that most of them are composed largely of oat 

 hulls, and consequently have a low feeding value. Samples Nos. 1494, 

 1962, 1505, 1705, 1499, 1518, 1914, 1934, and 1941, from their high ash 

 content (with the exception of No. 1518), their low protein, starch, 

 and fat content, the very high crude fiber and pentosan content, and 

 the microscopical examination, show that they are composed very 

 largely of hulls, while sample No. 1631, labeled as "ground oats/' 

 evidently contains hulls in considerable excess. Sample No. 1838 is 

 labeled " oat feed," and in chemical composition corresponds quite 

 closely to ground whole oats, but a microscopical examination shows 

 it to be a mixture of oats and corn with a small amount of some other 

 cereal, probably barley. Sample No. 1888, both from its chemical 

 composition and the microscopical examination, would appear to be 

 composed of ground oats.
