It will be s<M*n from these data that there is a distinct difference 

 between the foreign-grnxMi oatfi and t In >se gn >\\ n in the United States. 

 The f. ireign-gro\\n oats, such as the miscellaneous samples reported 

 by Kr.nig. the Mandard used hy Kelluer. and the 54 samples of 

 _:n>\\n nats analv/.cd in the present investigation, show these 

 diil'erenees plainly. Thi^ variation in coni|)()sition may be stated as 

 f..ll.t\\>: Oats grown in the Tinted States are characterized, as a 

 rule. l>y hiirher pr-.tein. |.\\er carhohydrate, lower fat, and higher 

 crude lil.er. These diflVrences in composition affect the production 

 value and the nutritive ratio, often making the former lower in the 

 oatfi LT<>\\n in the Tinted State-* and the latter narrower. The dif- 

 ferences in the production values are not great, however; the maxi- 

 mum dill'd'ence in poumU ..f llesh gained between the domestic- 

 S\\t-di>h Select oat (17.68 pounds) and the miscellaneous 

 oatfl analy/.ed in this bulletin (18.35 pounds) being only 0.67 

 pound, while the minimum difference between the highest domestic 

 oat and the lo\\e-i f.. reign oat was only 0.06 pound of flesh gained 

 per hundred pounds of oats fed. The results obtained in the pres- 

 ent studv afford a direct comparison of the foreign oat and the same 

 oat L r ro\\n in the Tnited States, since in most cases the domestic- 

 grown oat was obtained from the same seed as the sample from which 

 the anal\ -i- of the foreign oat was made.
