LOT 3. FED GRAIN AND SKIM MILK (I TO 8). 
Three pigs weighing on an average 25 pounds at the begin- 
ning, gained 110 pounds in 86 days. ‘The average daily gain 
was 1:28 pounds. ‘The feed required for 100 pounds of gain 
was 1,341 pounds of skim milk and 168 pounds of grain and 
cost $4.36. 
LOT 4. FED GRAIN ONLY. 
Three pigs weighing on an average of 25.3 pounds at the 
beginning gained 4o pounds in 86 days. ‘The average daily 
gain was 0.47 pound. The feed required for 100 pounds of 
gain was 445 pounds and the cost $4.45. 
In this trial the largest and most economical gains were made 
by those lots receiving milk and grain in combination. The 
least gains were made by the lot receiving grain only. At the 
arbitrary prices assumed for feed, the lot receiving skim milk 
only made gains at the greatest cost. 
While skim milk is easily digestible, it is too bulky in 
character. Or, to state it in another way, the capacity of the 
pig to digest and assimilate is greater than its capacity to con- 
sume this watery food. ‘The smaller gains made by the lot 
receiving shorts only may be attributed to the extra energy 
required to digest this food.

On the assumption that 100 pounds of skim milk will con- 
tain 8% pounds of solids and that they are all digestible, and 
that shorts contain 66 pounds of digestible nutrients, then the 
amount of digestible nutrients for 100 pounds of gain was lot 
I, 232.8; lot 2,232.2; lot 3,224.8, and-lot 4,294 pounds
