148 THE BUSINESS OF DAIRYING 



composition, cost, and ease with which it is grown. 

 It may be seeded at the rate of 12 to 15 pounds per 

 acre in corn at the last cultivation, or after a crop 

 of potatoes, without interfering with regular rota- 

 tions. The yield of hay will range from one to three 

 tons per acre. The method of curing should be 

 similar to that described for alfalfa. 



A feeding experiment.* This experiment was 

 conducted with four cows and continued 30 days. The 

 "crimson clover ration" contained 16.4 pounds of 

 crimson clover hay and 30 pounds of corn silage. 

 This was used in comparison with a "purchased feed 

 ration" composed of 30 pounds corn silage, 5 pounds 

 mixed hay, 6 pounds wheat bran, and 5 pounds dried 

 brewers' grains. The two rations supplied practically, 

 the same amount of dry matter and protein and car- 

 bohydrates, while the fat was somewhat greater in 

 the feed ration. The nutritive ratio for the crimson 

 clover hay ration was 1 15.7 and for the feed ration 

 1 :6.i. The crimson clover and silage were produced 

 entirely upon the farm, while over two-thirds of the 

 most expensive nutrient protein in the feed ration 

 was purchased. The home-grown ration proved a 

 practical one from the feeder's standpoint. There 

 was a saving of 18.3 cents per hundred in the cost 

 of the production of milk, and 3.73 cents per pound 

 in the cost of producing butter by feeding the home- 

 grown ration. Stated in another form, the gain 

 from feeding this home-grown ration over the pur- 

 chased feed ration amounted to $1.10 per cow per 

 month. On the basis of this experiment, when
