114 HATCH EXPERIMEXT STATION. [Jan. 



corn meal or corn and cob meal, served as the two grain 

 rations ; bran acted as a diluter of the heavy concentrates in 

 one case, and corn silage in the other. 



2. In the first experiment the results were slightly favor- 

 able to the bran ration, Avhile in the second experiment the 

 conditions were reversed. The diflerences were so trilling 

 that it may be said that for practical purposes both rations 

 produced equally satisfactory results. 



3. As a practical deduction, the ^vriter would suggest that 

 farmers who keep comparatively small herds, and who per- 

 sonally look after the feeding, may reduce the quantity of 

 2)?n'chased grain to 3 or 4 pounds daily per head, and sub- 

 stitute home-grown corn in place of wheat bran. Five to 7 

 pounds of grain daily is the usual allowance for cows pro- 

 ducing about 10 (juarts of milk of average quality. This 

 grain mixture may consist of \y-2 })ounds of cotton-seed 

 meal, 2 pounds of flour middlings and 2^/^ to 3 pounds of 

 corn or corn and cob meal daily ; or 11.'2 pounds of cotton- 

 seed meal, 2 pounds of oat middlings or rye feed and 21/^ to 

 3 pounds of corn meal. Malt sprouts may be substituted for 

 the wheat, oat or rye middlings. The several grains after 

 being mixed should be distributed throug-h the silao^e or cut 

 hay with the aid of a fork. This method of feeding will 

 enable the farmer to get along with a minimum cash outlay 

 for grain (4l/'2 cents daily), and at the same time he will be 

 supplying a Avell-balanced ration, rich in elements of fertil- 

 ity. The method will be more particularly suited to farmers 

 not having easy transportation facilities, and who sell their 

 dairy products to the creamery. 



4. Farmers and dairymen who cannot closely supervise 

 the feeding, and who desire to feed more than 5 to 7 pounds 

 of grain daily, will probably find it advisable to use one- 

 third to one-half wheat bran in compounding the grain mix- 

 ture. Distillers' grains and malt sprouts have also been 

 shown to be quite satisfactory distributers of the heavj^ con- 

 centrates.^
