Maternal nest-building performance and fetal number in Rockland-Swiss albino mice.
A significant correlation was shown in Rockland-Swiss albino mice between the number of fetuses and maternal nest-building performance as assessed by the amount of nesting material gathered into the cage. The greater the number of fetuses, the more nesting material was gathered. A significant correlation first appeared on Day 4 and was maintained until Day 18 of gestation.
