3G Report of the Department of x\nimal IIusbandhy of the 



Class III. Contain 14 per ct. to 20 per ct. protein and 70 

 per ct. to 75 per ct. carbohydrates : Brans and middlings from 

 wheat and rye and some proprietary mixed feeds. 



Class IV. Contain 8 per ct. to 14 per ct. protein and 75 per ct. 

 to 85 per ct. carbohydrates: Cereal grains, cerealine, hominy 

 and oat feeds, corn and oat chops, corn bran, corn germ feed and 

 chop feed in general. Hays and fodders belong here more nearly 

 than elsewhere. 



Samples of feed have been collected during the past two winters 

 and analyzed chemically, physically and often microscopically. 



Cotton-seed meal should be light yellow, a dark color usually 

 indicating inferiority. Protein may range from 42 per ct. to 

 46 per ct. or more in good samples. Of IG samples only two 

 showed evidence of adulteration, but the price did not follow 

 percentage of protein. 



Old, or pressure, process linseed meal and new, or naphtha ex- 

 traction, process meal differ m"ainly in fat, the former containing 

 three or four pounds more per hundred. Protein of new process 

 meal is perhaps less digestible because of cooking. Nineteen 

 samples were examined and all were good. One was somewhat 

 low in protein with no sign of adulteration. 



Gluten meals consist mainly of hard or flinty portions of corn 

 after bran, germ and part of the starch have been removed. They 

 should contain at least 30 per ct. of protein to be classed as meals 

 and may go to 40 per ct. Two samples analyzed were good but 

 the less nitrogenous sold for the higher price. 



The gluten feeds are a mixture of the meal with the bran and 

 germs and are less rich in protein than the meals, ranging from 

 18.8 per ct. to 28.1 per ct. This marked difference seems to be 

 quite constant between the brands, samples of Joliet and Diamond 

 brands running low. • 



Malt sprouts are the dried shoots from germinated barley. But 

 few samples were analyzed and these were found normal in com- 

 position, with from 24.66 per ct. to 30.37 per ct. of protein.
