various ]\y-products obtained in the manufacture of their breakfast 

 foods and similar products. These feeding stuffs vary in value, but 

 maj^ g-enerall}^ be said to represent the branny portion of the grains 

 from which they are derived. 



A comparison Avas made by E. B. and L. A. Voorhees" of dried 

 brewers' grains when substituted for oats, pound for pound, at the 

 New Jersey stations, eight horses heavily worked during the summer 

 being used. As shown by weight and general condition of the animals, 

 the brewers' grains were fully equal to the oats, pound for pound, 

 while their cost was considerably less. In a second trial, dried 

 brewers' grains were compared with a mixture of wheat bran and 

 linseed meal 5:1.5 when fed in addition to timothy hay and corn. The 

 uniformity in the amount of feed consumed and the weight of the 

 animals, taken in connection with the work performed, indicates that 

 there was no material difference in the value of the two rations. 

 According to calculations made (timothy hay at the time being worth 

 $18, wheat bran $17.50, corn meal $22, dried brewers' grain $17, and 

 linseed meal $29 per ton), a farm horse weighing 1,000 pounds can be 

 fed for $30.81 during the six months of the year when the most work is 

 performed if dried brewers' grain furnishes the bulk of the necessary 

 protein, and for $33.49 if wheat bran and linseed meal are the chief 

 sources of this nutrient. If the fertilizing value of the feeding stuff's 

 is taken into account the difference in favor of the brewers' grains is 

 less marked. 



In tests made by Emery ^ at the North Carolina Station horses were 

 satisfactoril}^ fed 2 pounds of cotton-seed meal per head daily as part 

 of the mixed ration. When the amount was increased to 3.5 pounds 

 the results were not as favorable. It is stated that neither of the 

 horses used in the test showed any symptoms which indicated that 

 cotton-seed meal disagreed with them. It is also stated that at the 

 Biltmore estate 2 pounds of cotton-seed meal per head daily were fed 

 to the horses and mules with 13 to 15 pounds of cut hay and finely cut 

 corn feed, 4 pounds of wheat bran, and 6 pounds of corn meal. On 

 Sunda3\s the ration was made up of whole corn and oats and uncut hay. 

 According to later information the feeding of cotton-seed meal has not 

 been found satisfactory at Biltmore. In the tests with mixed rations, 

 carried on at the New Hampshire Station (p. 18), the cotton-seed mix- 

 ture was least satisfactory. 



In the opinion of Director Stubbs, ^ of the Louisiana stations, cotton- 

 seed meal ma}" be fed with satisfactory results to horses and mules. 

 At the Louisiana stations 1 or 2 pounds per mule per day have been 

 fed with success. Six pounds is regarded as the maximum quantity
