2nd. "It required 1.04 pounds of alfalfa hay to re- 

 place 1 pound of grain. 



3rd. "The feeding of alfalfa afforded an excellent 

 means of getting the sows to take more exercise than 

 they do when fed grain alone. 



4th. "No trouble at all was experienced by any of 

 the sows in farrowing. 



5th. "The sows fed alfalfa hay farrowed just as large,

 receiving it. 



6th. "The sows fed alfalfa appeared to milk better 

 and nurse their pigs a little better than did those not 

 receiving hay. 



7th. "The results obtained in this trial indicate that 

 it is practical and advisable to feed as much alfalfa hay 

 to brood sows in winter as they will eat, regulating the 

 additional grain ration so as to keep the sows in the 

 proper condition." 



Methods of balancing corn for pregnant gilts. 



In Table VII are reported results of further investi- 

 gations by Evvard of the Iowa Experiment Station. In 

 this experiment a study was made of the relation of the 

 rations fed pregnant gilts during the winter to the weight, 

 vigor, and condition of the pigs produced.^ 



The corn fed in each ration was ear corn with the ex- 

 ception of the lot receiving cut clover, when it was shelled 

 to facilitate mixing. The meat-meal fed was the best 

 grade, containing 60 per cent protein and 14 per cent 

 mineral matter. The quantity of corn fed was estimated 

 on the shelled basis. The clover was of only fair quality,
