MISCELLANEOUS FEEDING STUFES. 

 I. ROOTS AND TUBERS. 



266. Yield of root crops. The Cornell Station 1 secured the fol- 

 lowing yields of fresh and dry matter per acre with various root 

 crops during three years of field trials. Potatoes are added for 

 comparison : 



Yield, water, and dry matter per acre in various root crops. 



267. Sugar beet, Beta vulgaris, var. This root has been marvel- 

 ously developed for the single purpose of producing sugar. Because 

 it sets deep in the ground the sugar beet is more expensive to culti- 

 vate and harvest than most other roots. If liberally fed, this root is 

 liable to produce scouring because of its high sugar content. Farm- 

 ers patronizing sugar factories should utilize cull beets as well as 

 the tops. (656, 757, 873) 



268. The mangel, Beta vulgaris, var. Tho the most watery of all 

 roots except the white turnip, the mangel has a high total dry mat- 

 ter content because of its enormous yield. As the large roots stand 

 well out of the ground, the mangel is easily cultivated and har- 

 vested. Tho it yields less dry matter per acre than the sugar beet, 

 only half the labor is required to harvest the mangel, and further- 

 more this root keeps better than the sugar beet. The mangel is use- 

 ful for all kinds of farm stock except possibly the horse. Day of 

 the Ontario College 2 found that equal weights of pulped mangels 

 and grain caused pigs to fatten faster and on less dry matter than
