steers in the five groups, showing the growth during tho various stages and 

 the feed requirements found neces.sary to convert a calf into a 1,200-lb. steer, 

 loady for marlvet, in approximately two years : 



Average iceights and gains per steer, feed consumed and total cost of feed 

 consumed per steer, and cost per pound of gain. 



Data on two of the groups turned out to pasture as yearlings are given. 

 Their weight as yearlings averaged 601.9 lbs. The steers were returned at the 

 proper time, weighing an average of 707.6 lbs., and after a week's preliminary 

 feeding were started on a feeding experiment. They were kept in an open 

 runway, but twice a day were confined to stanchions while they were taking their 

 morning and evening rations. The following table shows the average gains 

 made and feed consumed :

The average feed cost per steer for the first year was $30.4S and for the 

 second year after returning from pasture, $35.84. 



The difference in cost of production between the steers on continuous stall- 

 feeding and those turned to pasture the second year affords data on the benefits
