July 15,1921 Effects of Some Cucurbita Seeds on Animal Metabolism 529 
dams in one of the main hog lots where field corn was grown. They 
were weaned about three weeks prior to the experiment. 1 The males 
were castrated about two weeks previous to experimentation. The 18 
pigs selected were divided into three lots, each consisting of 6 pigs, 3 
barrows and 3 sows. The pens in which the pigs were confined were 
similar in every respect. Previous to experimental feeding the pigs 
received standard wheat middlings as a thin, wet mash, and whole corn, 
hand-fed. 
On October 26 the animals were ear-tagged for identification and dipped 
in about a 3 per cent creolin solution against vermin. Four days were 
allowed for the animals to adapt themselves to the new conditions. 
On October 30 their initial weights were taken (Table IX). Each self- 
feeder of each pen was filled with known amounts of yellow dent corn 
kernels, digester tankage, and standard wheat middlings. The “can¬ 
nery” seeds used in this experiment were purchased from a canning 
factory where pumkpins and squashes were packed. The pumpkins 
fed to the animals were the ordinary sugar pumpkin (Cucurbita pepo) 
chopped up fine (about 1 ee. in size). On November 1 the animals were 
dewormed by administering internally through the mouth 32 drops of 
worm-seed oil to 1 fluid ounce of castor oil to each pig.
