Effects of amaranth on F1 generation mice.

The color additive, amaranth, was given in the diet to provide dietary levels of 0 (control), 0.03, 0.09 and 0.27%, from 5 weeks of age in F0 generation mice to 9 weeks of age in F1 generation mice, and some reproductive, developmental and behavioral parameters were measured. There was no effect on the parameters of litters, litter size, pup weight and litter weight. The body weight of pups during the lactation period in the treatment groups increased less significantly, and the survival index at postnatal day (PND) 21 of the amaranth 0.27% group was reduced. Developmental parameters, direction of swimming on PND 4 in male pups and olfactory orientation in each sex were significantly reduced in the treatment groups. The dose levels of amaranth in this study influenced some reproductive, developmental and behavioral parameters in mice.
