ROWTH rate and efficiency of feed utilization are two of the most economically important
characters in the production of meat animals. In these days of world shortage of both plant …

The efficiency of food utilization, the digestibility of foodstuffs, energy metabolism, and body
activity have been studied in three lines of mice, one selected for large, another for small …

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 …

Selection for feed conversion substantially influenced growth and gross feed efficiency of
mice. Realized heritabilities and genie correlation for increased gain on fixed feed intake …

An examination was carried out of the feed intake, feed efficiency and body composition of
selected and unselected mice. It was demonstrated that selected mice utilised food more …

Chemical composition of whole carcasses of mice from three replicate lines selected for
rapid growth rate and from an unselected control line was determined each generation for …

Weekly food intake and body weight were measured from 3 to 17 weeks of age on mice
selected 14 generations for increased and decreased values of one of three criteria: appetite …

Four lines of mice were created from F2's of highly inbred lines. One of the lines was
maintained as a control line; in the other three lines an initial nine generations of mass …

Mice were selected for one of three criteria: appetite (A), measured as 4-to 6-week food
intake, adjusted by phenotypic regression to minimize change in 4-week body weight, fat …

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 …
