Differences in the metabolic resource situation between non-reproductive male and female
mice of a line selected for high litter size at birth (average of 22 born per litter) and a non …

Culling alternatives based upon number of litters, age of parents and interval between litters
were evaluated in 27 crosses from three random-mating, unselected strains of mice (S, J, P) …

The metabolizable energy intake (MEI) required for maintenance and the efficiency of
utilization of metabolizable energy available for gain (MEA) were determined for a line of …

MATERIALS AND METHODS The base population was a cross of four inbred lines
(C57BL/6JJ, AKR/J, C3H/J, DBA/2J). Details of the formation of the stock and of the …

Correlated responses in growth, body composition and efficiency were evaluated in lines of
mice selected in the following ways: W+ T io, increased six-week body weight (WT6); W° T …

Mass selection for increased body weight gain from 21 to 42 days of age was practiced for
12 generations in four replicate lines of ICR-albino mice. Response to selection averaged …

Breeding pairs of mice which had been selected over seventeen generations for large and
small 6-week body-weight (L and S mice), together with breeding pairs of the original …

MATERIALS AND METHODS The mice used in the present study came from the LCA and
LCB lines which had been se-lected for short tails and high body weight and vice versa …

Replicated within full-sib family single-trait selection was conducted for 10 generations in
mice for (1) high or low 12-week epididymal fat pad percentage (100 x epididymal fat pad …

Previous research in this laboratory demonstrated the existence of a major gene (hg),
expressed as a homozygous recessive, which increases postweaning growth by 60% in …
