Methionine levels impacted embryonic implantation and pregnancy outcomes. A, The methionine‐free diet significantly decreased AFDI/BW, maternal weight gain and the number of implantation sites in rats. B, The methionine‐free diet significantly decreased litter size, live litter size and live litter weight and increased the coefficient of variance (CV) of the birthweight of rat pups born alive. C, The diet containing 1.0% methionine significantly increased the number of implantation sites. D, Litter size, live litter size and live litter weight were increased in 1.0% methionine group. n = 30
