alfalfa is not as satisfactory for fattening hogs as a ration of corn alone, or a ration 

 containing a larger proportion of corn and a smaller proportion of alfalfa. 



(4) Alfalfa meal proved more satisfactory than chopped alfalfa when the 

 ration consisted of one part of alfalfa to three parts of corn. 



(5) In three tests with 90 pigs, a ration containing 9 parts of corn to 1 part 

 of alfalfa proved more profitable than corn alone, 



(6) When the alfalfa comprised only one-tenth of the ration, chopped alfalfa 

 and alfalfa meal gave almost the same gains, but the chopped alfalfa proved more 

 profitable owing to its lower cost. 



(7) In three tests with 90 hogs, the feeding of corn with alfalfa hay in a rack 

 gave very similar returns to feeding 9 parts of corn mixed with 1 part of chopped 

 alfalfa, with the difference in favor of rack feeding. 



(8) The results of 5 years' indicate that for fattening hogs the way to feed 

 alfalfa most satisfactorily is to feed it without grinding or chopping. 



(9) In these tests, 50 pounds of hay were worth more in the ration than a 

 bushel of corn. 



(10) The rations used in these tests are ranked in order of merit as follows: 



1st. Corn and alfalfa hay in a rack. 



2nd. 9 parts corn and 1 part chopped alfalfa. 



3rd. 9 parts corn and 1 part alfalfa meal. 



4th. Corn alone. 



5th. 3 parts com and 1 part alfalfa meal. 



6th. 3 parts corn and 1 part chopped alfalfa. 



7th. 1 part corn and 1 part chopped alfalfa. 



8th. 1 part corn and 1 part alfalfa meal. 



(11) It is recommended to feed the finest and brightest hay possible. Hogs 

 will not eat the coarse stems.

Roots. — In Henry's "Feeds and Feeding" there is an excellent summary 

 of Danish experiments with roots for swine. The meal equivalent of roots was 

 found to vary in a marked degree in different trials, and 100 pounds of barley 

 ^vere found to he equivalent to 600 to 800 pounds of mangels and 400 to 800 

 pounds of stock beets. In the United States and Canada, wide variations in 

 the meal equivalent of roots have also occurred in various tests. The following 

 table gives an idea of the range of values found at several stations : 



Meal Eqcivatent of Roots. 



Central Experimental Farm 100 pounds meal = 786 pounds roots 



Ohio Experiment Station 100 pounds meal = 642.5 pounds roots 



Montana Experiment Station 100 pounds meal = 529 pounds roots 



Utah Experiment Station 100 pounds meal = 455 pounds roots- 

 Ontario Agricultural College 100 pounds meal = 441.5 pounds roots 



Average 100 pounds meal = 570.8 pounds roots 



The variations in these trials are similar to the variations in the Danish 

 experiments. Ontario obtained a remarkably high meal equivalent for roots, and
