Response to selection for up (U) and (D) 3-to 9-wk gain in rats on average daily gain (ADG),
average daily feed intake (ADD, gain/feed (G/F), body composition (BC), fasting metabolic …

Average daily feed consumption (ADFC) and feed efficiency (FE, gain/feed) from 21 to 42
days of age were measured in three groups of mice during generations 11 through 14 of a …

Growth to 6 wk of age and food conversion efficiency between 21 and 42 days were
determined for mice from 3 types of selection lines after 11 generations of selection. The …

A replicated eight-generation selection experiment for increased early post-weaning gain
(G21–42)(line 1) and increased ratio (R) of early post-weaning gain to total post-weaning …

Reproductive performance was evaluated on lines of rats selected 34 generations for up (U)
and down (D) 3-to 9-wk weight gain and from a control (C). Direct response to 3-to 9-wk …

MATERIALS AND METHODS In forming the foundation stock for the selection experiment,
an effort was made to obtain a stock that was genetically diverse. Four highly inbred lines of …

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 …

Abstract Effects from 34 generations of selection, either up (U) or down (D), for 3-to 9-wk
weight gain on genetic direct and postnatal maternal effects, dam size and maternal …

Selection for post-weaning weight gain in mice from 21 to 42 days, on either a full or
restricted feeding level during this period was carried out for seven generations. Control …

Direct and correlated responses were evaluated for nine generations of full-sib family
selection for postweaning rate (LG) and efficiency (LE) of protein deposition in rats …
