"Protein is furnished more cheaply by oat preparations than by those of corn or 

 wheat. The oats also supply fat 10 times as cheaply as the corn products and 5 

 times as cheaply as the wheat foods. The carbohydrates are supplied most econom- 

 ically by the corn preparations, oats ranking second. In fuel value, oats again rank 

 first. 



"If wheat flour be included in the comparison, it will be found to be the cheapest 

 source of protein and carbohydrates. With the exception of one sample of rolled 

 oats, it also leads in fuel value." 



Commercial feeding stuffs in the Connecticut market, E. H. 



Jenkins, A. L. Wixton, et al. {Connect leaf State Std. Bui. 130^ 

 fj). Ifi). — Commercial feeding stuffs and their uses are briefly dis- 

 cussed, and the anal^yses of a large number of such materials reported. 

 These were made in compliance with the Connecticut law regulating 

 the sale of these goods and include cotton-seed meal, linseed meal, 

 ground wheat, bran, middlings, mixed wheat feed, corn meal, gluten 

 meal and gluten feeds, hominy chop, ground oats, provender, corn and 

 oat feeds, oat feeds, corn, oats, and barley, rye bran and rye feed, 

 malt hulls, starch feeds. Champion Bell Fodder, H, O. dairy feed, 

 H. O. horse feed, H. O. poultry feed, American Cereal Company's 

 Quaker Dairy Feed and Poultry Food, Blatchford's Calf Meal, Pioneer 

 Clover Meal, carob bean, carob liean pods, carob beans and pods, 

 Barnes's Horse and Stock Feed, Bowker's Animal Meal, and Lederer's 

 Poultry Food, 



"No cases of actual adulteration have been found among the samples examined. 

 A considerable number of these 'feeds,' notably most of the so-called 'oat feeds,' 

 are, however, of such inferior quality that they can not be used to any profit. 



"It appears that the three most concentrated feeds, the three which, pound for 

 pound, will go farther in 'balancing' or piecing out the ration made from home- 

 grown feed, viz, cotton seed, linseed, and Atlantic gluten meal are the most costly. 

 This is as it should be. Yet of these, the one which contains the most protein, 

 'Atlantic gluten meal,' is the cheapest. It does not follow that it should be bought 

 to the exclusion of the others. Linseed meal, though a ver}' expensive feed, is greatly 

 relished by cattle, flavors the food and is generally regarded as an excellent thing to 

 keep cows 'in condition.' But evidently the wise feeder will endeavor to use the 

 cheaper forms of protein as far as possible. 



"An examination of the prices and analyses of the feeds given in the table also 

 shows that the market prices bear very little if any relation to their feeding value. 

 That is, 'feed' costs from $17 to $20 per ton at retail, whether it is concentrated, 

 rich in protein, and well suited to supplement the home-grown feed, or whether it is 

 a starchy food and of much less \'alue in compounding suitable cattle rations. In 

 this condition of the market, special care in the purchase of feeds and some knowl- 

 edge of their chemical composition will be found highly advantageous in keejiing 

 the cost of milk production down to a point which will admit of profit in the 

 business. ' ' 



Analyses of feeding stuffs, H. A. Huston and A. H. Bryan {Indi-

 okra seed, buckwheat, Rauh's stock food, distillery slop, and a num- 

 ber of samples of mangel-wurzels and sugar beets. The protein con-
