A Nutritional Study of Yeso Sika Deer (Cervus Nippon Yesoensis) under Farming - Review -
T. Masuko, Y. Ishijima
Abstract
Yeso sika deer (Cervus nippon yesoensis) grazed on various types of plants, and the fiber content in these plants was low. The tastes of yeso sika deer for existing feeds for ruminant livestock resembled those of sheep. Though the digestibility of these feeds in yeso sika deer was slightly lower than that in sheep, the nutritive values of DCP and TDN were similar between the two species, suggesting that feed for sheep can be utilized. Therefore, in small-scale farming of yeso sika deer, the feeding amount in feeding planning can be determined using the feeding standards for sheep. However, when concentrates are fed, correction of TDN is necessary. In large-scale pasturage, the nutritional intake in summer is adequate because yeso sika deer graze on various types of wild plants. In winter, they mainly graze on sasa (Sasa senanensis), and supplementary food may be necessary to supply TDN. Thus, since yeso sika deer graze on many types of wild plants, existing feeds for ruminant livestock can be used. In addition, plant biomasses except concentrates that do not cause competition with existing livestock may be effectively utilized in yeso sika deer, suggesting their importance as animal resources. The data on the intake and nutritive values of Sasa senanensis can be parameters for estimating the appropriate inhabitant number of wild yeso sika deer in wintering areas.
