Ground Oats 



The variation from normal in the ground oat samples analyzed indicates in 

 general the use of a No. 3 or No. 4 oat, and sometimes an even lower grade. 

 The fat content of barley is much lower than that of oats, consequently the 

 presence of barley in any considerable amount will lower the fat content of the 

 mixture. Normal oats contain between 4 and 5 per cent of fat, a figure seldom 

 reached in the ground oats found on the market. Sixteen and one-half per cent 

 of protein in the Delaware Mills sample could indicate the addition of cereal by- 

 products of higher protein content than that carried by the cereals themselves. 



Of especial interest are the samples manufactured by the Northwest Distribut- 

 ing Co., the Flambeau Milling Co., and two unidentified samples sent by the 

 Northampton State Hospital. All of these samples carried an ash content much 

 in excess of normal. Analysis of several of these samples indicated the presence 

 of lime or calcium carbonate. One sample from the Flambeau Milling Co. had 

 a calcium content equivalent to 5.5 per cent calcium carbonate; another, 5.8 

 per cent; a sample from the Northwest Distributing Co., a calcium carbonate 

 content of 2.4 per cent. An unidentified sample from the Northampton State 

 , Hospital contained calcium equivalent to 4.29 per cent calcium carbonate. A 

 microscopic examination of the sample showed it to contain ground oats, wheat, 

 and barley, together with a large amount of oat hulls, stems, and weed seeds. 

 It could be considered as nothing more than oat screenings. 



These inferior samples were collected when freight embargoes were in force. 

 Any kind of feed was welcome and prosecution was not attempted. The in- 

 formation has been filed for further reference should their sale continue.
