A sex determination method using DNA extracted from feces has been developed for sika deer (Cervus nippon). We determined a partial sequence of the amelogenin gene of sika deer, which exists on both X and Y chromosomes with a deletion region on the Y chromosome. Based on the sexually dimorphic sequences, we designed a pair of primers which could amplify DNA fragments the lengths of which are different between males and females. PCR products were detected in 34 out of 37 fecal samples collected from captured deer and the sexes estimated by the present method were perfectly matched with the actual sexes.
