Effect of exposure to 1.65G during different developmental periods on litter size, mortality, cannibalism, and neonatal body mass at birth (mean ± S.E.M.). Litter size was most strongly affected by combined exposure during pregnancy and nursing (group E; p=0.0067); greatest mortality (p=0.0002) and cannibalism (p=0.053) of neonates was observed among pups exposed to 1.65G immediately after birth (group C); neonatal body mass was most affected by exposure during the 2^nd trimester of pregnancy (group A; p<0.0001).
