Extract

Low level feeding during lactations of greater than thirty five days duration has been shown to result in an extended weaning to remating interval and a reduction in subsequent litter size. The aim of this experiment was to examine whether this effect was a consequence of a reduction in ovulation rate and/or increased embryo mortality following such treatment.
