• Low intensity exercise and varying proportions of dietary glucose and fat modify milk and mammary gland compositions and pup growth.

• Animal technicians regularly socialized with the pups inside their pens.

• The vocalizations are a by-product of the pups' physiological response to cold stress that involves non-shivering thermogenesis in brown adipose tissue.

• Birth of pups after transfer of mouse embryos derived from vitrified preantral follicles.

• A total of 22 recipients were used for embryo transfer and one became pregnant, giving birth to seven normal, live pups 20 days after transfer.

• All pups from these two litters appeared normal.

• The scalp was then sutured, the pup warmed and returned to the dam.

• The female pronucleus to some extent also has effects on progeny hair colour, which is proved by the production of 2 pups with grey hair.

• They were weaned at 21-28 d, but many of the pups with ablated thyroids were very small and were left longer with their dam.

• Ten pups from five litters born during 1998 were monitored from weaning to approximately 12 weeks of age for nematode infections.

• Furthermore, cross-fostering studies demonstrate the importance of maternal behavior as a regulator of the development of regulatory systems in their pups.

• Recipient females were allowed to deliver and raise their own pups.

• Only rats that bred at least six pups were used.

• Among the 7 pups born, 5 were black and 2 were grey.
