Abstract:
Based on the plant biomass availability and the animal nutritional requirement for winter maintenance, the nutritional carrying capacity of winter range for moose (Alces aloes) was estimated during 1999~2000 in Shengshan forest farm in Heihe, Heilongjiang. Availa blc plant biomass supplied by environment was estimated based on the main food availability in moose winter habitat. According to the field investigation, moose main food in this area includes poplar, willow, birch and filbert. The nutritional requirements of moose for winter maintenance were determined based on the conventional digestion-metabolism trails of a captive moose. Finally, it is concluded that the nutritional requirements of the moose {or main tenance during winter, dry matter (DM), metabolizable energy (ME) and nitrogen (N) are: 4.73 kg/d, 7 5 558 kJ/d and 37.67 g/d respectively (the average weight of moose was estimated as 290 kg). The metabolizable energy is selected to reasonably estimate the moose winter nutritional carrying capacity, with the final results as: 76 (0. 005 4 moose/hm2) in 1999 and 109(0. 007 8 moose/hm2) in 2000.
