“…Previous studies reported that, in the mating season, several hinds were observed in large open habitats such as pastures where they could be easily found by stags and many stags chased the hinds without feeding in the pasture (Juan and Juliana 1999;Hiyama et al 2001). In addition, it was reported that the dry matter intake per metabolic body weight of group-fed sika deer was lowest during the mating season (Shiraishi et al 1996). Therefore, the decreased herbage consumption by deer in fall is taken to reflect the mating season, when deer used the pasture for breeding rather than for feeding.…”

Seasonal pasture utilization by wild sika deer (Cervus nippon) in a sown grassland

Pasture utilization by wild sika deer (Cervus nippon) was investigated in a closed communal pasture in Nagano, Japan, in terms of seasonal changes in the aboveground plant biomass, herbage consumption and animal density (estimated by fecal pellet count method). Pasture utilization by deer varied greatly with season. Herbage consumption was high before and after the major hunting months (December–January) in winter and in summer. In fall, herbage consumption was low despite high aboveground plant biomass and deer density. Both herbage consumption and deer density tended to be low in the major hunting months and spring. A significant positive correlation (r = 0.71, P = 0.01) was observed between monthly deer density and aboveground plant biomass of the pasture. The results show that pasture utilization by deer was affected mainly by plant biomass and also by the nutritive quality of herbage, deer mating season and deer hunting. It is likely that the pasture was utilized by deer as a breeding site as well as a feeding site.

“…On the other hand, it has been shown that captive sika deer exhibit to a large extent the features of wild deer living under a situation in which food availability and quality changes seasonally (Odajima et al 1992;Shiraishi et al 1996). In general, the voluntary feed intake (VFI) and growth rate of Cervidae that have evolved in temperate or boreal latitudes are seasonal, and the annual cycle for VFI and growth rate reaches a maximum in summer and a minimum in winter (Barry et al 1991).…”

To investigate seasonal variations in the digestive functions of sika deer, five female sika deer were provided with an amount of alfalfa hay cubes equivalent to voluntary food intake during winter. We measured the rate at which the food passed through the digestive tract, digestibility and rumen fermentation during the summer (August), autumn (November), winter (February) and spring (May). Total mean retention time in the digestive tract during summer and autumn was numerically longer than that in winter and spring, but the difference did not reach significance. Organic matter and fiber were less digestible in summer and autumn than in winter and spring (P < 0.05), whereas the digestibility of the dry matter tended to vary with the seasons (P < 0.1). Ruminal pH values seasonally changed (P < 0.01), and were the lowest in autumn. The concentration of ruminal ammonia‐nitrogen differed significantly among the seasons (P < 0.05), increasing in winter and decreasing during spring and summer. The numbers of protozoa changed significantly among the seasons (P < 0.05), being higher in autumn than in winter and spring, and intermediate in summer. The concentration of total volatile fatty acids was not seasonally affected, but the molar percentages of propionic acid and butyric acid significantly changed according to season (P < 0.05 and P < 0.01, respectively), and the ratio of acetic to propionic acid tended to change with the seasons (P < 0.1). The results of this study suggested that the digestive functions in sika deer, fed a commercial diet at a restricted level, differed notably among the seasons and these variations might partially be due to environmental effects.

Body weights of 21 artificially reared sika deer (Cervus nippon), including 10 males and 11 females, were measured from birth until 24-36 months of age, and the data were analyzed. The increases in body weights of the males and females from birth to 3 months of age were almost the same. However, the rate of increase in body weights of males became greater than that of females after 4 months of age, and this difference became greater with the advance of age. The rate of increase in body weights of females, but not of males, became asymptotic after 30 months of age. A significant inter-family difference was found in body weights of the deer from 4 to 12 months of age, suggesting the influence of genetic factors on growth rate. Significant differences between sexes, but not between families were found in rate of maturing, body weight at the inflection point on the logistic growth curve and growth rate. The inflection points on the logistic growth curves for males and females, which were thought to indicate the onset of puberty, were 8.5 and 7.3 months of age, respectively.
