ites when cost of keep is not a prime requisite. In 1844 the great 

 French chemist and farmer, Boussingault, conducted the most ex- 

 tensive studies of roots for horse feeding ever carried on. His find- 

 ings 1 may be summarized as follows: 



That 280 Ibs. of cooked potatoes mixed with cut straw are equal to 100 

 jbs. of meadow hay. 



That 350 Ibs. of carrots cannot quite replace 100 Ibs. of good meadow hay. 



That artichokes were greedily eaten by horses, which thrived on them, 

 30 Ibs. of sliced tubers taking the place of 11 Ibs. of meadow hay. 



That 400 Ibs. of rutabaga turnips (swedes) are about equal to 100 Ibs. of 

 meadow hay. 



445. Stock food. Grisdale of the Ottawa Experimental Farms 2 

 gave 1 horse in each of 5 work teams the amount of International 

 Stock Food indicated in the directions accompanying the package, 

 the other horse in each team receiving no condimental food. All 

 received 14 Ibs. a day of an oats-and-bran mixture for concentrates. 

 The horses getting the stock food made an average total gain of 

 12 Ibs. each in 42 days, while those getting no stock food made an 

 average gain of 13 Ibs. each. Grisdale reports that in appearance 

 and spirit the horses getting no stock food were the equal of their 

 mates fed stock food. (343) 



446. Fleshing horses for market. With three expert horse deal- 

 ers for counsel, Obrecht of the Illinois Station 3 studied the cost of 

 fleshing horses for the market. Thirteen Eastern chunks were divided 

 into 3 groups and fed the rations given below for 84 days :
