Feed utilisation for fasting metabolism and for fat and protein deposition was evaluated in
rats selected for 14 generations for rapid (LG) or for efficient (LE) postweaning lean growth …

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 …

Net income in meat animal enterprises is a function of the value and quantity of the product
marketed and its cost of production. Since feed accounts for a major share of production …

Full-sib family selection for rate (WP) or efficiency (WP/F) of protein gain in rats from 3 to 9
weeks of age was applied for five generations. Three rats per litter were killed to estimate …

Two lines of mice were selected for growth rate from 3 to 6 wk of age, line SF under ad lib.
feeding and line SR under restricted feeding (82% of ad lib.). Each treatment had a separate …

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 …

Full-sib family selection for rate (LG) and for efficiency (LE) of protein gain was based on 3 to
8-or 9-week protein gain with bulk-feeder (B) cages for the LG line and on protein gain per …

Effects on components of net life-cycle input costs/gram of lean tissue output were modelled
for responses from 14 generations of family selection for rate (LG) or for efficiency (LE) of …

Mice selected for high (H 6) and low (L 6) 6-week body weight and a randombred control
population (C 1) were characterized for rate, composition and efficiency of growth. Individual …

Correlated responses in feed efficiency, feed consumption and body composition were
investigated after nine generations of selection for weight gain in two age intervals, 28 to 38 …
