FEEDING STUFF INSPECTION. 57 



The analyses of 61 samples are reported. The guaranteed 

 percentages of protein for the cottenseed meal varied from 41 per 

 cent to 43 per cent ; the fat was all guaranteed 9 per cent. 



The 61 samples carried from 40 to 49.31 per cent of protein 

 with an average of 45.52 per cent. The fat ranged from 7.70 per 

 cent to 12.91 per cent with an average of 9.73 per cent. No low 

 grade cottonseed meal was found by the inspector and none has 

 been sent by correspondents thus far during the season of 1901-2. 



GLUTEN MEALS AND FEEDS. 



Gluten meals and gluten feeds are by-products left in the 

 manufacture of starch and glucose from Indian corn. Corn con- 

 sists largely of starch. The waste product from the manufac- 

 ture of starch or sugar is relatively much richer in oil and protein 

 than corn. Most factories are removing part of the corn oil 

 from the waste, so that nearly all the gluten meals carry but little 

 oil, e. g., Chicago Gluten Meal, which three years ago carried 

 7 to 9 per cent of fat, now has from 2.50 to 4 per cent. This 

 reduction in fat is probably an advantage, as feeding corn oil to 

 dairy animals seems to have a tendency to make softer butter. 

 Gluten feeds differ from gluten meal chiefly in that they contain 

 a good deal of the corn bran and hence relatively less of protein 

 and digestible carbohydrates, and more of the indigestible woody 

 fiber. 



Chicago Gluten Meal is for the most part guaranteed to carry 

 38 per cent protein and 2 per cent fat. None of the samples 

 examined came up to the guarantee in protein. The average of 

 the samples examined was nearly 2 per cent below the guarantee. 

 The goods are not as good as last year but resemble those offered 

 in the State in the summer and fall of 1899. 



Chas. Pope Glucose Company's Cream Gluten Meal is guar- 

 anteed 34.12 per cent protein and 3.20 per cent fat. The lowest 

 sample carried 33.38 per cent and the highest 41.44 per cent pro- 

 tein, with an average of 37.82 per cent. Not only were those 

 goods for the most part above the guaranteed per cent of protein, 

 but they averaged the highest of the gluten meals examined. 



The National Starch Company's King Gluten Meal carried 



guarantees in which the protein ranged from 32.4 to 39 per cent 



and the fat from 3.2 to 4.3 per cent. The protein in the samples 



analyzed ranged from 31.63 to 38 per cent. These goods aver-
