Limits to sustained energy intake XXIV: impact of suckling behaviour on the body temperatures of lactating female mice.


ABSTRACT: The objective of this study was to investigate the potential causes of high body temperature (Tb) during lactation in mice as a putative limit on energy intake. In particular we explored whether or not offspring contributed to heat retention in mothers while suckling. Tb and physical activity were monitored in 26 female MF1 mice using intraperitoneally implanted transmitters. In addition, maternal behaviour was scored each minute for 8?h d(-1) throughout lactation. Mothers that raised larger litters tended to have higher Tb while nursing inside nests (P?
