pigs on pasture than for those <>n grain alone; the average daily gains 
were nearly 29 per cent greater, and there was a saving of more than 
lOpereenl in t.he feed per LOO pounds gain for the pigs on pasture. 
I'alin of a grain ration with pasture. — The converse of the Utah 
experiments is shown by two experiments by Morrow and Bone a in 
Oklahoma. 
Two lots of -4 pigs each were placed in half-acre alfalfa Lots, one 
being given a full feed of grain and the other receiving none. Tn 
eight weeks the lot without grain had gained only 68 pounds, or 17 
pounds each, and those having grain gained 324 pounds, or 81 pounds 
each. 
A sow with a litter of o pigs was in the same lot with the grain-fed 
pigs. The sow gained 61 pounds in thirty- five days, when she was 
removed. Her 5 pigs made a total gain of 146 pounds in the first five 
weeks and 96 pounds during the succeeding period of three weeks. 
The grain fed these pigs amounted to only 221 pounds per 100 pounds 
gain. 
Pasture in addition to dairy by-products. — Four tests were made in 
Utah 6 to determine the value of pasturing pigs that are receiving a 
ration of grain, milk, and whey. One test was made with pasturing 
pigs that were receiving milk and whey, but no grain. The ratio of 
milk to grain by weight was 5 : 1 at the start and 3 : 1 at the close in the 
second and third tests. In the fourth test the grain was limited to 
one-half the quantity fed the other lots, but all the milk and whey 
was given that the pigs would take. 
The pigs that received the grain and dairy by-product ration were 
fed in pens. 
The following table shows the results for each test and the average
