Indices for nutritional condition and thresholds for winter survival in sika deer in Hokkaido, Japan.
We derived fat indices for sika deer (Cervus nippon yesoensis) in eastern Hokkaido, Japan, and estimated the probability of over-winter survival with a logistic regression model using fat indices. Kidney fat mass (KFM) appears to be an adequate index of wide range of physical conditions before the onset of severe nutritional stress. When KFM values fell below 20 g, femur (FMF) and mandible cavi...
متن کاملFetal age estimation of Hokkaido sika deer (Cervus nippon yesoensis) using ultrasonography during early pregnancy.
In sika deer, the normal method of estimating fetal age, based on fetal weight, is not applicable during the early pregnancy period. The objective of the present study was to describe the growth and development of sika deer fetuses and to establish a method for fetal age estimation during early pregnancy using ultrasonography. Five captive female Hokkaido sika deer (Cervus nippon yesoensis) wer...

Serum samples from 8 of 83 (9.6%) cattle reacted with Rickettsia helvetica antigens in an IFA test, with titers ranging from 1:160 to 1:640, while serum samples from 15 of 22 (68.2%) deer were positive for R. helvetica, with titers ranging from ...
متن کاملHistological differences of skin among three body regions in male and female Hokkaido sika deer (Cervus nippon yesoensis).
The Hokkaido sika deer (Cervus Nippon yesoensis), the largest and most abundant of the sika deer subspecies in Japan, has recently attracted new attention as a target for leather production, in addition to its meat value. To provide fundamental data for facilitating the effective use of skin for leather, the histological properties of skin at the shoulder, back and abdominal regions of male and...
متن کاملOverabundance of sika deer and immunocontraception
The impact of deer overabundance is a worldwide problem. Along with habitat expansion and population increase, damage by sika deer to the forest ecosystem and agriculture has become a serious issue in Japan. Deer also transmit a number of diseases and parasites to humans and livestock. The overabundance of deer is a result of their strong fecundity, and therefore the present situation should, i...
