The time and period of the day during which several ruminant species dedicate to different activities (time budget) varies along the year. Pampas deer (Ozotoceros bezoarticus, Linnaeus, 1758) is an endangered species that lives in the southern cone of South America. Our aim was to describe seasonal variations of pampas deer female time budget under semi-captivity conditions. The study was performed at the Estación de Cría de Fauna Autóctona Cerro Pan de Azúcar (Uruguay), with 31 females pampas deer housed in 6 breeding groups composed by 1 stag, 3-6 hinds and fawns. The behavior of each deer was recorded using instantaneous scan sampling every 15 m for approximately 8 h per day. On summer they spent more time lying and less time grazing (P < 0.0001); on winter, more time standing and eating ration (P < 0.0001), and on spring the time that they spent ruminating was maximum (P < 0.0001). At least in the conditions of this study, pampas deer females' time budget was strongly influenced by season.

半圈养潘帕斯鹿 (Ozotoceros bezoarticus) 雌性的时间预算季节性变化

几种反刍动物从事不同活动的时间和时段（时间预算）随一年而变化。潘帕斯鹿 (Ozotoceros bezoarticus, Linnaeus, 1758) 是一种生活在南美洲南锥体的濒危物种。我们的目的是描述半圈养条件下潘帕斯鹿雌性时间预算的季节性变化。该研究是在 Estación de Cría de Fauna Autóctona Cerro Pan de Azúcar（乌拉圭）进行的，将 31 只雌性潘帕斯鹿饲养在 6 个繁殖组中，由 1 只雄鹿、3-6 只母鹿和小鹿组成。每天大约 8 小时，每 15 m 使用瞬时扫描采样记录每只鹿的行为。夏季，它们躺着的时间更多，放牧的时间更少（P < 0.0001）；在冬季，更多的时间站立和进食（P < 0.0001），而在春季，它们花在反刍上的时间最长（P < 0.0001）。至少在本研究的条件下，潘帕斯鹿雌性的时间预算受到季节的强烈影响。
