以广州动物园人工饲养的10只环尾狐猴（雄性5只，雌性5只）为研究对象，根据广州地区多雨潮湿的气候条件，以400m。草地作为饲养场地，配置栖枝、凉亭和恒温保暖箱，采取逐只投喂的办法进行饲养。在广州地区的气候条件下，环尾狐猴2岁即可进行繁殖交配，发情期为8～9月，妊娠期为5个月，育幼主要由母猴来完成，雄猴可参与育幼，母猴有明显的护食行为。当气温低于15℃时，狐猴进入恒温保暖箱活动。在华南地区的气候条件下，环尾狐猴的饲养管理需做好防雨、防晒工作，冬季气温低于15℃时需开启恒温保暖设施。在繁殖育幼期，需添加面包虫等食物，并合理搭配成年雌雄性狐猴比例，防止动物打斗而出现伤亡。本文主要阐述环尾狐猴在广州地区的饲养繁殖、防寒保暖、环境丰容等方面的技术要点，为在华南地区环尾狐猴的保育及进一步研究奠定基础。 相似文献

血液生理指标的测定可以为动物的饲养繁殖及健康状况提供一定的科学依据。空腹采集上海动物园圈养健康环尾狐猴(Lemur catta)的血液样本,分别用人工镜检法和全自动血液分析仪测定7项血液生理参数,对检验结果进行分析,并得出这些常规指标的变动范围和最佳的检测方法,以实现对环尾狐猴血常规的快速准确分析。结果显示,两种检验方法获得的结果中白细胞计数、中性粒细胞比率、淋巴细胞比率差异不显著(P0.05),红细胞计数、单核细胞比率、嗜碱性粒细胞比率、嗜酸性粒细胞比率差异显著(P0.05);白细胞计数(r=0.971)、单核细胞比率(r=0.887)、淋巴细胞比率(r=0.967)、中性粒细胞比率(r=0.879)应用两种方法获得的结果相关性较好;红细胞计数(r=0.493)、嗜酸性粒细胞比率(r=0.256)的相关系数都较低,且P值接近或大于0.05,呈弱相关或极弱相关。针对环尾狐猴的血液生理指标检测,仪器检验在某些方面具有稳定、快速的特点,但考虑野生动物细胞的特殊性,应与人工镜检结合,以提高检验结果的准确性。 相似文献

2017年3—6月,在上海动物园笼养环尾狐猴展区布设定时饲喂器,探讨其对环尾狐猴(Lemur catta)行为的影响。采用瞬时扫描法记录环尾狐猴行为,分析环尾狐猴的行为变化及其对定时饲喂器的认知。开展定时饲喂器丰容后,环尾狐猴的休息行为显著减少,移动和取食行为显著增加(Mann-Whitney U,P<0.05),对展区空间利用发生了显著变化(chi-square test,P<0.05)。环尾狐猴通过学习,适应了定时投喂器的工作模式,并形成了相应的行为模式。本次丰容在短时间内效果较好,但在后期,动物的反应速度减慢。 相似文献

In September 2008, two ring-tailed lemurs (Lemur catta), comprising a mother-daughter pair, at the Greenville Zoo, Greenville, South Carolina, USA, were diagnosed with cuterebrid myiasis (Diptera: Oestridae) subsequent to sudden death of the adult lemur. On necropsy, a single bot warble was discovered in the subcutis of the axillary region. Histopathology revealed a severe eosinophilic bronchopneumonia. The juvenile lemur was inspected and found to have warbles on three separate dates in late September. One representative bot fly larva was identified as a Cuterebra sp. that normally infests lagomorphs in the southeastern United States. Cuterebrid myiasis is rarely reported in lemurs and has not been previously associated with pneumonia or death in these animals. 相似文献

A female ring-tailed lemur (Lemur catta) and her two cubs held in a zoo in Chile exhibited signs of severe hepatic insufficiency. In spite of supportive treatment, the three animals died a few days after the onset of signs. Postmortem examination revealed ascites and fibrotic lesions in the liver of all the individuals. Histologically, the liver of two of them showed a severe parasitic ova infection and lipidosis, the morphologic characteristics of the parasitic ovas were consistent with Capillaria hepatica (syn. Calodium hepatica) eggs. To the authors' knowledge, this is the first clinical case report of hepatic capillariasis in prosimians, and its implications are discussed. 相似文献

A 13-yr-old ring-tailed lemur (Lemur catta) was evaluated for depression, anorexia, polyuria, and polydipsia. The lemur was in poor body condition and was anemic, hypoalbuminemic, and hyponatremic. Cytologic examination of aspirates of the spleen, liver, and bone marrow and histopathologic examination of liver and bone marrow biopsies revealed a disseminated round cell tumor. After euthanasia, necropsy revealed hepatomegaly, splenomegaly, and mesenteric lymphadenomegaly. Neoplastic cells were present within the spleen, liver, kidneys, multiple lymph nodes, bone marrow, lung, small intestine, pancreas, and testicle and were composed of large anaplastic round cells in a background of small well-differentiated lymphocytes. Immunohistochemical analysis revealed that the small well-differentiated lymphocytes labeled for the anti-human T-cell marker, CD3, and the large anaplastic round cells labeled with the anti-human B-cell marker, CD79a. On the basis of the immunohistochemical staining results and morphologic appearance, a diagnosis of a T-cell-rich B-cell lymphoma was made. 相似文献

The prevention of calculus accumulation in exotic animals is a relatively unexplored topic. A 6-mo study in ring-tailed lemurs (Lemur catta) and collared lemurs (Eulemur fulvus collaris) and two studies in baboons (Papio cynocephalus) (7.5 wks and 6.5 mo) tested the benefits of a primate diet coated with 0.6% sodium hexametaphosphate (HMP) in controlling calculus in these species using a sequential crossover design. The control regimen was an identical, but non-HMP-coated, dry primate chow. At study initiation, the primates were given a thorough dental prophylaxis and provided with the control diet or experimental diet. At the conclusion of the test period, the animals were anesthetized and examined for clinical calculus independently by two examiners. The animals were then given another dental prophylaxis, provided the alternate ration, and the foregoing procedures were repeated. When the animals were provided the HMP-coated diet, significant reductions in calculus formation of 48-62% were observed in the lemurs and the baboons. No clinically significant changes were observed in body weights or in blood chemistry values as a result of ingestion of the HMP-coated regimen. 相似文献

In the current study, we determined the seroprevalence of Toxoplasma gondii, Sarcocystis neurona, and Encephalitozoon cuniculi in three species of lemurs from St. Catherines Island, Georgia. Serum samples were tested from 52 ring-tailed lemurs (Lemur catta), six blue-eyed black lemurs (Eulemur macaco flavifrons), and four black and white ruffed lemurs (Varecia variegata variegata) using an agglutination assay. Three ring-tailed lemurs (5.8%) were positive for T. gondii (titer of 1:50); one ring-tailed lemur (1.9%) and one black and white ruffed lemur (25%) were positive for S. neurona (titers of 1:1000); and one ring-tailed lemur (1.9%) was positive for E. cuniculi (titer of 1:400). All blue-eyed black lemurs were negative for antibodies to T. gondii, S. neurona, and E. cuniculi. This is the first detection of antibodies to T. gondii in ring-tailed lemurs and antibodies to S. neurona and E. cuniculi in any species of prosimian. 相似文献

Complete health assessments were performed on 20 adult ring-tailed lemurs (Lemur catta), 10 males and 10 females, free ranging within the Tsimanampetsotsa Strict Nature Reserve in southwest Madagascar. Each animal was anesthetized using tiletamine and zolazepam, weighed, and given a thorough physical examination. Blood was collected for hematology, determination of plasma total protein concentration, serum chemistry, determination of fat-soluble vitamin and trace mineral concentrations, assessment of iron metabolism, toxoplasmosis and viral serologies, and examination for parasites. Feces were collected for bacterial culture and parasite examination, and representative numbers of ectoparasites were collected. Blood values differed significantly in a number of ways from values in captive lemurs, possibly associated with recent food consumption, hydration, and diet. There was no evidence of serious infectious disease and no hemoparasites. The enteric flora appeared unremarkable, although results may have been skewed toward cold-tolerant bacteria. The fecal parasite burden was low, but there were large numbers of ectoparasites (mites) present. Our study demonstrated that a substantial amount of data can be collected from free-ranging populations, information that is invaluable in the management of captive populations, particularly with regard to disease, and in assessing risks associated with reintroduction programs. 相似文献

OBJECTIVE: To assess serum iron and ferritin concentrations, total iron-binding capacity, and transferrin saturation as indicators of iron metabolic status in 3 genera of lemurs and determine whether these variables are useful for screening for iron overload. DESIGN: Cross-sectional study. ANIMALS: 11 ring-tailed lemurs (Lemur catta), 11 black lemurs (Eulemur macaco macaco), and 11 red-ruffed lemurs (Varecia rubra). PROCEDURES: Blood samples were collected weekly for 3 weeks and assayed for serum iron and ferritin concentrations and total iron-binding capacity. Liver biopsy specimens were evaluated histologically and assayed for total iron, nonheme iron, and trace mineral concentrations. Deposition of iron was scored on Prussian blue-stained slides. RESULTS: Hepatic iron content ranged from 497 to 12,800 Pg/g dry weight (median, 2,165 Pg/g). Differences were seen in mean hepatic iron content across genera, with ruffed lemurs having the highest concentrations and ring-tailed lemurs having the lowest. Iron accumulation in the liver was mild, and cellular pathologic changes associated with iron storage disease were not detected in any lemur. Ferritin concentration was the only variable that correlated significantly with hepatic iron content in all 3 genera of lemurs; however, both transferrin saturation and serum iron concentration were correlated with hepatic iron concentration in ring-tailed and ruffed lemurs. CONCLUSIONS AND CLINICAL RELEVANCE: Serum ferritin concentration was the only variable that was consistently correlated with hepatic iron content in all 3 genera. Mean hepatic iron content varied across genera, suggesting that the propensity for lemurs to develop iron overload in captivity may vary across taxa. 相似文献
