麝(Moschus)是亚洲东部特有的小型反刍动物,是珍稀濒危资源动物。因麝机警灵敏,胆怯性急,耐受力差,传统的取样方法会造成不同程度的伤害,不利于保护野生种群和可持续利用麝资源。收集粪便和毛发样品是在不触及动物或低干扰动物正常活动的情况下进行的,有助于麝资源的保护。文章系统总结了麝科动物粪便和毛发的取样方法及其在麝科动物遗传多样性、疾病、应激反应、生殖生理等方面的应用研究,并对粪便和毛发取样法在麝科动物的应用前景进行展望。 相似文献

为了解原麝(Moschus moschiferus)适宜生境的空间分布及生境需求,对其栖息地管理和保护提供科学依据,以陕西宜川原麝省级自然保护区为研究区域,应用GIS结合保护区红外相机、野外实测原麝分布点数据,利用R语言对MaxEnt模型优化后建模,对保护区原麝栖息地适宜性进行评价并分析各变量因子的权重值。结果表明:模型预测结果良好,保护区内原麝适宜栖息地面积约为61.36 km 2,占保护区总面积的30.75%;次适宜栖息地面积约为100.32 km 2,占保护区总面积的50.28%;不适宜栖息地面积约为37.86 km 2,占保护区总面积的18.97%。植被类型、海拔、坡度和距河流距离是贡献率排前4的环境因子。保护区内人为因素干扰比较小,原麝在针阔混交林、海拔1 200～1 500 m和坡度20°以上的生境中出现概率较高,建议根据生境适宜性调整保护区范围(尤其是实验区范围),并在山体之间建立廊道,加强对原麝及其生境的保护。 相似文献

多年来,原麝胃肠炎是我场圈养原麝的常见病之一,1978年至1983年间原麝胃肠炎发病率占麝群发病总数的75％,死亡率占死亡总数的60％以上,6年因此病共死亡11O头,从而,极大地影响了我场原麝麝群的发展和麝香产量的提高。为了寻求治疗原麝胃肠炎的有效方法和预防措施,1982年以来,我们对原麝胃肠炎的病因进行了观察、分析。并开展了治疗试验,由于预防措施比较得力,治疗及时,初步控制了原麝胃肠炎的发病和死亡,现原麝胃肠炎的发病率已大幅度下降,治愈率也由开始的40％提高到95％以上。现对原麝胃肠炎的发病原因及其治疗、预防措施等进行以下的初步探讨。 相似文献

林麝 ( Moschus moschiferus beresovskii)被列为国家二级保护动物 ,同时又是珍稀的药用和香料动物 [1-2 ]。我国开展人工养麝 40多年来 ,麝的疾病一直是制约养麝业规模化发展的主要因素之一 ,其中以传染病及寄生虫病的发病率最高。邬捷 ( 1 983)、沙国润 ( 1 995 )先后对野生及家养林麝寄生虫种类作了调查与研究[3 -4] ,曾报道在野生林麝体表发现毛虱( Trichodects) [3 ] ,但有关家养林麝毛虱的危害情况尚未见报道。 1 998年以来 ,笔者发现四川养麝研究所都江堰养麝场家养林麝发生牛毛虱病 ,并选用杀虫药物进行了防治试验。报道如下。1 … 相似文献

In late December 1984, 1853 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1984 and 35% of them responded. Veterinarians reported that 97,794 dogs were blood-tested to check for microfilariae and 1417 dogs (1.45% of those tested) were found with heartworm. Another 34 dogs were amicrofilaremic, but were diagnosed as having heartworm disease, to give the total number diagnosed in 1984 as 1451 (1.48%). Heartworm was reported from all provinces except Prince Edward Island and Newfoundland but most (1310) of the cases were in Ontario. In Quebec, 126 cases were reported mostly from west of Montreal. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 27% of the cases were observed with clinical signs of heartworm disease and 72% had a history of not having left Canada. Southwestern Ontario continued to be the primary focus of the infection. 相似文献

In late December 1983, 2 800 veterinarians across Canada were sent a questionnaire in order to assess the status of heartworm disease in Canada in 1983 and 26% of them responded. Veterinarians reported that 59 504 dogs were blood-tested to check for microfilariae and 771 dogs (1.30% of those tested) were found with Dirofilaria immitis. Heartworm disease was diagnosed in all provinces except New Brunswick and Newfoundland but most (733) of the cases were in Ontario. Heartworm disease was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 31% of the cases were observed with clinical signs of heartworm disease and 64% had a history of not having left Canada. Southwestern Ontario continues to be the focus of the infection and most of the dogs there had not left the province previously. 相似文献

In late November 1991, 1883 clinics in Canada were sent a questionnaire to assess the status of Dirofilaria immitis in dogs in 1991 and there was a 60.0% response. There were 344,031 dogs tested for heart-worm (HW), 627 were found infected and the prevalence of HW infection was 0.18%. There were 417 dogs with HW in Ontario, 116 in Manitoba, 38 in Quebec, 53 in British Columbia, three in Alberta, and one in Nova Scotia. In British Columbia, all of the infected dogs but one were from the Okanagan valley which, as from 1991, is a new focus of infection in Canada. Most dogs with HW had not been on preventive medication in 1990, and the prevalence among dogs tested and unprotected was 0.59%. That prevalence was considerably higher in endemic areas. Companion dogs, over three years of age and maintained primarily outdoors in rural areas, were most frequently infected. One cat was diagnosed with D. immitis and 33 dogs had Dipetalonema reconditium. 相似文献

In late December 1985, 1485 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1985 and 44% of them responded. Veterinarians reported that 137,300 dogs were blood-tested to check for microfilariae and 1210 dogs were found with heartworm. Another 36 dogs were amicrofilaremic but diagnosed with heartworm disease to give the total number diagnosed in 1985 as 1247 (0.91%). Heartworm was reported from all provinces except Prince Edward Island, Newfoundland and Saskatchewan but most (1126) of the cases were in Ontario. Southwestern Ontario continued to be the primary focus of the infection in Canada. From Quebec, 91 cases were reported mostly from and around Montreal. From Manitoba, 19 cases were reported from Winnipeg and surrounding areas. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 28% of the cases were observed with clinical signs of heartworm disease and 78% had a history of not having left Canada. 相似文献

In late November 1989, 1732 clinics and institutional veterinarians were sent a questionnaire to assess the status of Dirofilaria immitis, and 51.7% responded. Of 247,716 dogs tested, 394 had D. immitis microfilariae and 51 were amicrofilaremic for a total of 445 cases and heartworm prevalence of 0.17%. Most (408) of these dogs had no preventive medication and the prevalence among dogs tested and unprotected was 1.01%. That prevalence was considerably higher in endemic areas. Thirty-seven dogs with heartworm had preventive medication. Heartworm was most frequent in companion dogs over three years of age maintained outdoors in rural areas. About 75% of the cases had never left Canada, 26% had clinical signs and 125 were not treated. Heartworm was reported from British Columbia, Manitoba, Ontario, Quebec, Nova Scotia and Newfoundland, but 383 cases were in Ontario. South-western Ontario was the primary focus of infection. There were 33 cases in Quebec and 24 in Manitoba, mainly found in and around Metropolitan Montreal and Winnipeg respectively. 相似文献

In late December 1986, 1224 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1986; 46% of them responded. Veterinarians reported that 150,989 dogs were blood-tested for microfilariae and 869 dogs were found with heartworm. Another 65 dogs were amicrofilaremic but diagnosed with heartworm disease and one was found with heartworm at necropsy to give the total number diagnosed in 1986 as 935 (0.62%). Heartworm was reported from Manitoba, New Brunswick, Ontario and Quebec, but most (810) of the cases were from Ontario. South-western Ontario continued to be the primary focus of the infection in Canada. There were 103 cases reported from Quebec, mostly from and around Montreal, and 21 cases from Manitoba, from Winnipeg and surrounding areas. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 33% of the cases were observed with clinical signs of heartworm disease and 81% had a history of not having left Canada. 相似文献
