Effects of various degrees of undernutrition of mice on pregnancy and conceptus
Maternal intake of drastically (1/2 of control) and substantially (1/2 of control) reduced feeding was studied in pregnant mice during gestation and embryonic development. Resorptions, fetal mortality rate and fetal weight were significantly affected by maternal undernutrition during the treatment period. The number of fetuses with intrauterine weight retardation was also significant.
