Heat production (HP) of male and female mouse deer during eating, standing
and sitting was determined using the open circuit respiration chamber (RC).
The time taken for similar activities was also determined in an outdoor en
closure (OD). The animals were fed kangkong (Ipomoea aquatica), sweet potat
o (Ipomoea batatas) and rabbit pellet ad libitum. Male mouse deer consumed
more dry matter (DM), organic matter (OM) and gross energy (GE) than female
. The time for each activity of male and female mouse deer kept in RC and O
D was similar. The average time spent in RC and OD for both male and female
, respectively, for sitting (956 and 896 min/day) was significantly (P < 0.
01) longer than standing (463 and 520 min/day) and eating (21 and 24 min/da
y). Heat production for male and female mouse deer, respectively, during ea
ting was the highest (0.4.4 and 0.43 kJ/kg W-0.75/min) followed by standing
(0.37 and 0.33 kJ/kg W-0.75/min) and sitting (0.26 and 0.26 kJ/kg W-0.75/m
in). The difference in HP per min during standing between male and female w
as significant (P < 0.05). The HP for 08.00-14.00 h and 14.00-20.00 h perio
ds were higher than 20.00-02.00 h and 02.00-08.00 h periods. The overall HP
for males during 08.00-14.00 h and 14.00-20.00 h periods were significantl
y (P < 0.05) higher (114.8 and 119.2 kJ/kg W-0.75) than female (107.5 and 1
10.4 kJ/kg W-0.75), respectively. (C) 2001 Elsevier Science Inc. All rights
