A review is presented of the genetic and physiological aspects of growth, body composition
and feed efficiency in mice. The genetic parameters considered are: nature and extent of …

We conducted a two-way selection experiment in a composite rabbit population to
investigate the responses to selection for postweaning ADG and feed conversion (FC). Two …

Changes in the pattern of food intake, food conversion efficiency and growth from weaning
to maturity, were examined in 35 rams and ewes from flocks of Merino sheep selected for …

An experiment was carried out with New Zealand White rabbits to study the effect of four
generations of selection on body weight at an age of 112 days. The response given as …

A single generation divergent selection study, replicated four times (1983, 1984, 1985, and
1986), was conducted to assess genetic differences between progeny of high and low feed …

Bidirectional restricted index selection was conducted for 10 generations in mice. The goal
was to maximize genetic change in postweaning weight gain from 3 to 6 weeks of age, while …

Two Nellore herds were compared, one selected for greater postweaning weight and the
other, control, selected for average postweaning weight, to evaluate the effects of 29 years of …

This study aimed to test the hypothesis that if animals were fed the same amount over the
same time period, selection of the fastest growers would result in a change in the partitioning …

An automated method was used to record the temporal pattern of feeding of lines of mice
selected over 15 generations for high and low body weight (L-mice and S-mice …

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 …
