鼠鹿或雪豹是有蹄目动物和反刍动物中最小的。它们的一些特征被认为是偶蹄目的多形性特征。这项研究的目的是检查较小的老鼠-鹿的睡眠，它是这一组中最小的老鼠-鹿(体质量和体重2.2公斤)。在越南卜家地图国家公园，使用遥测系统记录了四只成年老鼠-鹿的脑电、颈项肌电、眼电和身体加速度。鼠鹿在非快速眼动睡眠(NREM)中的平均睡眠时间为49.7±3.0%。REM睡眠占总睡眠时间的3.2±0.5%，占总睡眠时间的1.7±0.3%。REM睡眠平均持续时间为2.0±0.2min，最长为5.1±1.1min，最长持续时间为8min。NREM睡眠发生在胸骨卧位，头高出地面，而64.7±6.4%的REM睡眠发生在头着地。在NREM睡眠的大部分时间里，眼睛都是睁着的。鼠鹿表现出多相睡眠和黄昏活动高峰(04：00-06：00和18：00-19：00)。上午(06：00-09：00)NREM量最大，黄昏前(04：00-06：00)NREM量最小。REM睡眠发生在大部分白天时间(08：00-16：00)和上半夜(19：00-02：00)。我们认为，小鼠-鹿的睡眠模式和时间适合于生活在热带森林灌木丛中的一种小型草食动物的生存，这种动物容易被捕食，生活在高温环境中。
The mouse-deer or chevrotains are the smallest of the ungulates and ruminants. They are characterized by a number of traits which are considered plesiomorphic for the Artiodactyla order. The objective of this study was to examine sleep in the lesser mouse-deer (Tragulus kanchil), which is the smallest in this group (body mass < 2.2 kg). Electroencephalogram, nuchal electromyogram, electrooculogram, and body acceleration were recorded in four adult mouse-deer females using a telemetry system in Bu Gia Map National Park in Vietnam. The mouse-deer spent on average 49.7 ± 3.0% of 24 h in non-rapid eye movement (NREM) sleep. REM sleep occupied 1.7 ± 0.3% of 24 h or 3.2 ± 0.5% of total sleep time. The average duration of REM sleep episodes was 2.0 ± 0.2 min, the average maximum was 5.1 ± 1.1 min, and the longest episodes lasted 8 min. NREM sleep occurred in sternal recumbency with the head held above the ground while 64.7 ± 6.4% of REM sleep occurred with the head resting on the ground. The eyes were open throughout most of the NREM sleep period. The mouse-deer displayed polyphasic sleep and crepuscular peaks in activity (04:00–06:00 and 18:00–19:00). The largest amounts of NREM occurred in the morning (06:00–09:00) and the smallest before dusk (04:00–06:00). REM sleep occurred throughout most of the daylight hours (08:00–16:00) and in the first half of the night (19:00–02:00). We suggest that the pattern and timing of sleep in the lesser mouse-deer is adapted to the survival of a small herbivorous animal, subject to predation, living in high environmental temperatures in the tropical forest undergrowth.
