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 …

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 …

After seven generations of selection, a line of mice selected for post-weaning (21–42 days)
weight gain on full feeding (SF) showed significant increases of 49% in weight gain, 31% in …

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 …

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 …

Selection was practised for improved feed efficiency (gain/feed intake) of mice on two
alternative feeding regimes. In one set of lines animals were fed ad libitum, in the other set …

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 …

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 …

Genetic and phenotypic variation in post-weaning growth, food intake, efficiency and body
composition of mice post weaning and at maturity, were examined to determine whether …

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 …
