the other lots Bhowed a marked advantage from pasture might be 
explained by the skim milk in the ration. Ii isperhapsa safe propo- 
sition that in feeding pigs bho besl results will followthe use of dairy 
by-products, roots, or pasture, in connection with grain, but thai it 
is superfluous to combine two of these supplementary feeds, as their 
action on the digestive system seems to be similar. When attempts 
are being made to prevent disease, however, the advantage of ample 
exercise must not be overlooked. 
Corn compared with wheat on alfalfa pasture. — At the Nebraska 
Station/' Burnett and Smith placed three lots of 6 pigs each on alfalfa 
pasture lots one-fourth acre in area. The pigs were Tamworth- 
Duroc Jersey crossbreds. Lot I was fed ground corn; Lot II, a ration 
composed of 95 per cent ground corn and o per cent dried blood, and 
Lot III received ground wheat. In addition to the pasture, all the 
pigs had one week on rape. The experiment lasted forty-two days. 
The results follow :

a Expense of pasture and labor considered. 
The cost of feed in this experiment was, for corn, $1 per hundred- 
weight; wheat, 81.10 per hundredweight, and dried blood, $2.50 per 
hundredweight. The results are so close together that a slight 
change in the prices of feed would change the relative rank of these 
rations. The value of pasture is apparent when these results are 
compared with those of the experiment at this station with wheat and 
other grains. (See p. 98.) 
Maintaining pigs on pasture alone. — At the Utah Station Foster 
and Merrill 6 conducted two tests to observe the effect of maintaining 
pigs on pasture alone. 
According to Henry/ no station has shown that pigs can be success- 
fulty maintained on pasture alone if the test reported from the Utah 
Station is excepted. The further investigations at this station on this 
line are therefore of much interest. 
In 1898 a comparison was made of mixed pasture and alfalfa pas- 
ture. The pigs were about five months old at the beginning of the test, 
had been fed grain and milk, and were in a very thrifty condition. 
Both lots had access to running water.
