New York AGRICULTURAL EXPERIMENT STATION. 107 
both experiments increase in weight was less regular and there 
were much wider fluctuations in the individual weekly gains under 
the wet food ration. 
CORN OR CORN MEAL.! 
A limited experiment was made comparing corn on the cob with 
an equivalent amount of corn meal for pig feeding. There was not 
much difference in the amount of food consumed under the two 
rations, although it was slightly less under the ration with corn meal, 
but during both of the periods of feeding increase in weight was 
much faster under the corn meal ration. 
Over 30 per ct. less dry matter in the food per pound gain in 
weight was required during both periods by the pigs fed corn meal 
and the cost per pound gain was from 16 to 18 per ct. less than when 
corn on the cob was fed. 
FEEDING EXPERIMENTS WITH YOUNG PIGS.” 
Feeding experiments were made to get data as to the relative rate 
and cost of growth made by pigs fed with and partly by the sow, 
and when fed separately, and of those kept with the mother for 
longer and shorter periods. Detailed data were published from 30 
feeding trials in this connection in which pigs of six pure breeds 
and pigs of seven first crosses were fed. - The pigs were fed with 
the dam until from four to nine weeks old, usually until the age of 
six weeks, weekly records being kept. 
Practically without exception much less food (on the basis of 
dry matter) was required per pound total live weight fed when 
young pigs were fed alone than while fed with the sow. With very 
few exceptions, and these during severe weather, the increase in 
weight made by the pigs after removal from the sow cost much less 
‘per pound than during the period just before separation or ever 
during the first few weeks with the mother. By considering the 
cost of restoring the weight lost by the sow while giving milk the 
difference was much greater. In several feeding trials made to de- 
termine the cost of bringing back the weight lost by the sow (and 
this weight was very rapidly restored), it was found that the cost 
per pound was much greater than the cost of increase with pigs, not 
far from twice as great as the average with young pigs about twa 
months old.
