HOME-GROWN DAIRY FOODS FOR WINTER USE 153 



mated nutritive ratio of 1:5. The cowpea ration 

 was produced entirely on the farm, while two-thirds 

 of the protein of the feed ration was purchased. On 

 the cowpea hay ration the daily yield averaged 

 23.7 pounds of milk, containing 3.86 per cent, of fat; 

 on the feed ration it was 25.7 pounds of milk con- 

 taining 4.11 per cent, of fat. The feed ration pro- 

 duced 8.3 per cent, more milk, or 15.2 per cent, more 

 butter, than the cowpea ration. At market prices 

 for feeding stuffs the cost of producing 100 pounds 

 of milk was 39.8 cents, and of producing one pound 

 of butter 8.82 cents, when the cowpea hay ration 

 was fed. When, however, the feed ration was given 

 the cost of production was 60.5 cents per hundred 

 for milk and 12.6 cents per pound for butter. With 

 milk at $i per hundred these results indicated an 

 increased profit for a herd of 30 cows of $37.20 per 

 month from the home-grown ration over the feed 

 ration. However, it is believed that a combination 

 of coarse and fine feeds is necessary to produce the 

 best results. 



Soy bean silage and alfalfa hay. The soy bean is 

 a plant similar to the cowpea but grows a little 

 slower, has a tougher stalk, and is not quite as palat- 

 able or quite as sure a crop. However, good yields 

 are secured when conditions are favorable, and the 

 crop is worthy of mention as a home-grown food 

 and a possible substitute for expensive purchased 

 feeds.
