2010年11月—2013年2月,以上海动物园繁殖场内的10只赤斑羚(Naemorhedus cranbrooki)为研究对象,分别进行了2次环境丰容和食物丰容,分析了丰容前后对圈养赤斑羚活动时间分配的影响。结果表明:在加入丰容设施后,赤斑羚的卧息和刻板行为明显减少,摄食、移动和修饰行为明显增加,与预期结果一致;进一步增加丰容设施的复杂性后,卧息行为明显减少,移动和修饰行为明显增加,但其他几种行为变化不明显,未达到预期效果。在食物丰容阶段,卧息和其他行为有所减少,站立行为有所增加,但以上3种行为变化都不明显,未达到预期效果。在对丰容设施的利用上,进行食物丰容和增加丰容设施的复杂性有效地促进了赤斑羚对丰容设施的利用,分别使赤斑羚在丰容设施上活动的时间百分比由2.07%和1.44%提高到12.17%和10.83%。首次加入丰容设施后,赤斑羚在丰容设施上主要以站立行为为主;进一步增加环境复杂度后,赤斑羚在此设施上主要行为变为卧息行为。食物丰容前,赤斑羚在丰容设施上主要行为是站立行为;在食物丰容阶段,赤斑羚主要的行为变成了摄食行为。 相似文献

Stereotypic behavior is exhibited by a wide range of captive animals. Its association with hormones, especially elevated cortisol level and lack of naturalistic stimuli in the environment, has been little studied. This study hypothesizes that stereotypic behavior is caused by stress due to lack of appropriate, naturalistic stimuli in the environment. Using four adult pandas (Ailuropoda melanoleuca) in the Beijing Zoo from March–July in 2003, we tested the following predictions: 1) stereotypic behavior and fecal cortisol level will not change associated with the progress of reproductive state; 2) there is a positive correlation between the occurrence of stereotypic behavior and fecal cortisol level; and 3) environmental enrichment by adding a naturalistic stimulus will reduce both stereotypic behavior and fecal cortisol level. We did not find any significant differences in the occurrence of stereotypic behavior and fecal cortisol level but did find a significant difference in the total time engaged in displaying the stereotypic behavior among the three estrous periods. The level of stereotypic behavior was correlated with elevated fecal cortisol level. Enrichment simply by adding a naturalistic stimulus did not show significant effects on stereotypic behavior, or on fecal cortisol level. Our results supported the second prediction, but did not completely support the first and the third ones perhaps because of the small sample size. Additionally, our results showed that stereotypic behavior might be a response to a heightened level of cortisol. Zoo Biol 0:1–15, 2006. © 2006 Wiley‐Liss, Inc. 相似文献

This meta‐analysis reports the effect enrichment has on the occurrence of stereotypic behavior exhibited by captive zoo mammals. The analysis also identifies which types of enrichment are most effective, which groups of animals benefit the most, and which types of stereotypes are most affected by environmental enrichment. The analysis included 54 studies that yielded 63 effect size statistics. Fifty‐seven of sixty‐three effect sizes went in the predicted direction (90%), with the animals participating in less stereotypic behavior during the enrichment condition than in the baseline condition. The mean effect size (correlation coefficient r) was 0.46. The combined P‐value using both fixed and random effects methods was reveled to be <0.0000001. A file drawer N‐value was calculated to identify the number of unretrieved studies (with a combined effect size of zero) that would be needed to nullify the results of this analysis. The file drawer N‐value was 1,726, suggesting that it is highly unlikely that the significant results reported in this analysis are nullified by studies that remain in file drawers. Based on these results it was concluded that enrichment substantially reduces the frequency of stereotypic behavior exhibited by mammals living in zoo environments.

Age class differences in feeding behavior of primates are affected by many factors, including feeding competition, foraging skills, habitat type, food abundance and distribution, body mass, and food types. Two captive groups of Japanese macaques (Macaca fuscata), one housed in a forested enclosure and the other in a nonvegetated enclosure, were studied to examine the effect of environmental enrichment on age class differences in feeding behavior. Although there was no significant age class difference in time spent feeding on provisioned foods in either enclosure, the feeding rate (intake of unit food/minute) of adults consuming provisioned monkey chow was significantly higher than that of immatures in both enclosures, and was faster for both age groups in the nonvegetated than in the forested enclosure. Overall, feeding time was greatly extended for individuals of both age classes in the forested enclosure compared with their counterparts in the nonvegetated enclosure. Immatures in the forested enclosure utilized a significantly greater number of plant species and food items, exploiting many food items available among the terminal branches, and spent significantly more time feeding than adults. Perhaps constrained by larger body size, adults fed more often on the ground or middle height of the trees, likely reducing competition over plant food resources between adults and immatures. The natural vegetation played an important role in extending feeding time and segregating substrate use during feeding by adults and immatures. This study revealed the benefits concerning environmental enrichment of a naturally forested enclosure, which provides captive primates the opportunity to exhibit age class and species-typical feeding behaviors of importance for their dietary maintenance and general health. 相似文献

Captive small felids frequently pace repetitively and/or spend large amounts of time inactive. Presenting a fishing cat with live-fish resulted in more activity (60% less sleeping), increased behavioral diversity, including previously unobserved hunting behaviors, and greater enclosure utilization. Effects persisted for at least 48 h after presentation of live fish, and up to 8 days. In a second study, four leopard cats were fed: (1) once per day, (2) four times per day and, (3) four times per day with food hidden in small piles of brush. Multiple feedings of hidden food increased daily exploratory behavior from 5.5% to over 14%, and increased the diversity of behaviors observed. It also reduced the total duration, and bout length of stereotyped pacing. These studies suggest that providing food to small cats in a way that minimizes predictability of food availability, while maximizing the functional consequences of foraging behavior, can be an effective enrichment technique. These results are discussed in relation to two models of behavioral motivation, one that focuses on the issue of behavioral needs, and the other that emphasizes the importance of information acquisition. © 1993 Wiley-Liss, Inc. 相似文献

Environmental enrichment has been widely used to improve conditions for nonhuman animals in captivity. However, there is no consensus about the best way to evaluate the success of enrichments. This study evaluated whether the proportion of time spent interacting with enrichments indicated the proportion of overall behavioral changes. Six environmental enrichments were introduced in succession to 16 captive macaws, and interaction of the animals with them as well as the behaviors of the group were recorded before and during the enrichments. All of the enrichments affected the proportions of time spent in different behaviors. Macaws interacted more with certain items (hibiscus and food tree) than with others (a toy or swings and stairs), but introduction of the enrichments that invoked the least interaction caused as many behavioral changes as those that invoked the most. Moreover, feeding behavior was only affected by the enrichment that invoked the least interaction, a change not detected by a general analysis of enrichment effects. In conclusion, little interaction with enrichment does not mean little change in behavior, and the effects of enrichments are more complex than previously considered. 相似文献

Individuals adapt to changes in their environment, such as food availability and temperature, by adjusting the amount of time spent in different behavioral activities. These adjustments in behavior should vary across age-sex class according to specific physiological and social needs. We studied the activity budgets of three social Japanese macaque groups inhabiting either vegetated or nonvegetated enclosures in order to compare the effects of access with vegetation, as both food and substrate on resting, feeding, grooming and moving activities over a 12-month period. Daily access to natural foods for monkeys in the vegetated enclosure seems to be largely responsible for the differences in daily time budgets of these three groups. Resting time in all three groups was longer than the time devoted to other activities. Resting and moving time in the two nonvegetated enclosures was significantly longer than in the vegetated enclosure. In contrast, feeding and grooming time was significantly longer in the vegetated enclosure. Seasonal variation in time spent feeding, resting and grooming was significantly effected by enclosure type. In all three enclosures, immatures, particularly females, spent more time feeding and moving, whereas adults spent more time resting. Significant monthly variation in time spent by age-sex class was noted only for feeding and resting. Interestingly, in the vegetated enclosure, time spent feeding on natural vegetation was equal to the amount of time spent feeding on provisioned food. This suggests that factors other than energetic and nutritional needs may be important determinants of the activity budget of the species. These results have important implications for the enrichment of captive primates and our understanding of the maintenance of activity patterns by primates in the wild. 相似文献
