FEED AND MANAGEMENT. 59 



valuable experiment to show the effect of ex- 

 posure on milch cows. I clip the following 

 from that station's "Bulletin No. 47": 



The following points of importance are brought out in the 

 bulletin: 



1. That cows exposed during the day to the inclemency of 

 winter weather ate more food than those given the shelter 

 of a comfortable barn. 



2. That cows thus exposed gave on an average less milk 

 per day than those not so exposed, and much less milk as a 

 total, during the experiment, which extended over forty- 

 eight days in January, February, and March. 



3. That the cows which were exposed to the weather dur- 

 ing this experiment lost in weight, while those given barn 

 shelter gained in weight. 



4. That there is a difference of $12.79 in favor of shelter 

 for cows in winter. 



Some of the interesting details of this experi- 

 ment are herewith quoted: 



Grouped by lots each lot ate the following amount of food: 



Lot Ilbs. Lot IIlbs. 



Clover hay eaten 1996.2 1483.8 



Corn-meal 1239.0 1627.0 



Bran.. ..1168.5 1536.7 



Total 4403.7 4647.5 



Lot II, the exposed one., ate 243.8 Ibs. more food than lot 

 I, but less hay and much more grain, consuming 388 Ibs. 

 more of corn-meal and 368.2 Ibs. more of bran. The differ- 

 ence in the cost of the total amounts of food eaten has an 

 important bearing on the relationship of expense and in- 

 come. 



The cost of the food eaten is based on current market 

 prices in Lafayette at the time of the experiment. Clover 

 hay is quoted at $8 per ton, corn-meal at $1 per 100 Ibs., 

 and bran at 65 cents per 100 Ibs. The cost of labor was 

 no greater for lot I than for lot II, if it was as great, and is 

 not included in the discussion of the experiment.
