BULLETIN 488, U. S. DEPARTMENT OF AGRICULTURE. 
produced 1,488 pounds of gain. "Where 7.657 pounds of corn was fed 
the gain was 3.006 pounds: where 7.236 pounds of ground barley was 
fed the gain was 2.776 pounds, and where 12.760 pounds of corn sup- 
plemented the alfalfa pasture, the gain was 4,354 pounds per acre 
of pasture. With this information the farmer can apply prices 
that suit his own particular condition and determine the most eco- 
nomical quantity of grain to feed.

Two years' results show that more pasture is required when no 
grain is fed and that as the grain ration is increased the area of pas- 
ture required is decreased. The areas required when no grain. 1 per 
cent grain. 2 per cent grain, and 3 per cent grain were fed were ap- 
proximately as 5. 4. 3. and 2. respectively. 
For every 100 pounds of grain fed. lot 2 made 47.4 pounds of gain; 
lot 3. 38 pounds: lot 4, 38.3 pounds: and lot 5. 34.1 pounds. The 
higher the grain ration the lower the gains per unit of grain fed. 
Also, the lower the grain ration the more pasture was required for 
100 pounds of gain. 
With the prices here used, the two-year average net return per 
acre of alfalfa pasture were as follows: No-grain lot. $45.08; 1 per 
cent corn lot. 870.20: 2 per cent corn lot. 8125.49: 2 per cent ground 
barley lot. 8121.96: and the 3 per cent corn lot. 8168.25. The average 
daily net return per acre for 154 days ranged from 29 cents, where 
no grain was fed. to 81. OS. when a 3 per cent ration of corn was fed. 
The two-year average net return per acre of alfalfa pasture from 
lots 3 and 4 show the sum of 86.43 in favor of corn over ground 
barley. It will also be seen from Table V that the corn lot was fed 
a little more grain than the barley lot. Higher returns would, there- 
fore, be expected from the corn-fed lot. as the results have shown that 
the net returns for pasture increase with the grain ration. The dif- 
ference in net returns, therefore, is not enough to warrant the state-
