This study was to determine the response of young guinea pigs to
stilbestrol added to the basic ration of ground oats, tankage, bonemeal,
ground alfalfa hay, and freshly-cut, green alfalfa. Eight litters of
guinea pigs, each consisting of two pigs of the same sex were used.
These pigs ranged from 3 to 5 weeks of age and the initial weights
ranged from 220.7 to 368.6 grams. Four of the litters were males and
four were females. One male from each of the male litters was placed
in the control cage and the other pig from each litter was placed in
the treatment cage. The female litters were divided in a similar manner
and an effort was made to equalize the initial weights in the control
and treatment cages for each sex.
