Abstract

A litter of five meadow voles (Microtus pennsylvanicus) was cross-fostered on a white-footed mouse (Peromyscus leucopus). All Microtus pups survived through weaning. Daily weight gain was 0.30 gm before weaning and 0.96 gm after weaning. When weaned, the Microtus pups were approximately 1/3 normal size for that stage of development. The timing of post-natal physiological events was not affected by cross-fostering.
