Abstract
We applied the in situ hybridization technique to the Hokkaido sika deer (C ervus nippon yesoensis) caudal glands using probes designed from the red de er (Cervus elaphus) prolactin receptor cDNA. Prolactin receptor mRNA expres sion was consistently detected in the secretory epithelial cells collected from fawns and lactating hinds. This suggests that the presence of develope d caudal glands during late pregnancy and lactation may be caused by increa sed blood levels of prolactin. During late pregnancy and lacation, visual r ange is limited for deer in forests and grasslands because of the flourishi ng leaves and sprigs. Therefore, we suggest that the scent emitted from the caudal gland in a particular season coordinates with and reinforces the vi sual alarm effect of the rump patch and tail.
