Methods of Feeding on Forage 



213 



number of pounds of grain required to produce a unit 

 of gain is greater for pigs fed in the dry lot and at 

 heavier weights than for pigs on forage and of Ughter 

 weights, it is necessary to feed the different lots to the 

 same market weight before a reliable comparison can 

 be made. 



A study of the results of three series of experiments 

 recently made at the Iowa, Illinois, and Indiana stations,^ 

 together with the results of experiments covering the 

 forage period only, indicate that we may expect results 

 under the average of good farm conditions closely approxi- 

 mating those shown in Table LXXVIII.
