Feeds and Feeding. 



Having become accustomed to this feed the horses were weighed, 

 aud again when they had been on the feed for eleven days. The 

 average weight per horse was: first weighing, 1, 113 pounds; second 

 weighing, 1,114 pounds, — a gain in eleven days of one pound per 

 head. (323,868) 



489. Ruta-baga (Swede) turnip. — Boussingault fed 31 pounds 

 of Swede turnips in place of part of the hay in the ration. The 

 horses lost 52.8 pounds each in nine days, showing that the cal- 

 culated ration was too low. In another experiment with the 

 same horses where Swedes were introduced in the ratio of 400 : 100 

 of hay, the horees kept their weight at the point to which it had 

 fallen, but did not gain. 



II. Concerning Rations for Horses. 



490. Rations fed to Paris cab horses. — Tlie experiments by 

 Grandeau and Leclerc, the results of which are summarized 

 in another place, (442-8) were made with horses belonging 

 to the Paris Cab Company. The following table gives the daily 

 standard rations of the horses used by the company at the time 

 the experimental maintenance rations were fed, and the one 

 finally adopted as best for work. These horses weighed from 800 

 to 900 pounds each. The data, with description of the same, are 

 taken from Lawes and Gilbert's essay on feeding farm animals. * 



''It seems that the system of the establishment was to work the 

 horses on alternate days, and to give less hay, straw and corn, but 

 more oats and beans, though less total food, ou the days of work.
