Comparisons of ad libitum and restricted feeding of mice selected and unselected for postweaning gain. I. Growth, feed consumption and feed efficiency

MATERIALS AND METHODS The mice used in this study were obtained from 9th generation
selection and random control populations developed from a foundation ICR strain obtained
from the Institute of Cancer Research, Philadelphia, Pa. The selected line subsequently
designated High (H) was selected for

MATERIALS AND METHODS Progeny were from a line selected for nine generations for
high postweaning weight gain from 21 to 42 days of age and a random control line
originating from the same base population. Selected and unselected lines, hereafter referred
to as High and Control, respectively, were fed either ad libitum or restricted from weaning
(21 days) to 57 days of age. The litters were paired within sex on the basis of body weight at
weaning to form 27 blocks, each block consisting of 2
