Abstract

A comparison of intake, digestibility and nitrogen balance in spotted deer(Cervus nippon) fed forest by-product silage(FBS), arrowroot silage(ARS) and oak leaf hay(OLH) was made to examine the feeding value of forest by-product silage. Dry matter digestibility of ARS was significantly higher(p$<$0.05) than that of OLH while crude protein digestibility was significantly higher(p$<$0.05) in ARS and FBS than in OLH. The digestibility of crude fiber was highest in FBS. Dry matter intake of OLH was significantly higher(p$<$0.05) than that of ARS, and there was no significant difference with FBS. Nitrogen intake was higher in OLH and ARS than in FBS, but there was no significant difference. Fecal nitrogen was highest(p$<$0.05) in OLH and urinary nitrogen was highest(p$<$0.05) in ARS. Retained nitrogen was highest in FBS, however, there was no significant difference among treatments. In Conclusion. FBS was estimated as a useful roughage source for deer, showing high digestibility, dry matter intake and nitrogen utilization.
