藏鸡是西藏农牧民长期饲养,人工选择程度较低的原始品种。藏鸡能适应高寒恶劣多变的气候环境,是高海拔地区禽业中的当家品种。由于藏鸡产地多为高山峡谷,地形复杂、交通不便、商业不发达的半农、半牧区,加之历史的因素,历来都是自繁自养,饲养管理方式极为原始和粗放。 相似文献

探讨不同饲养方式对藏鸡生产性能和脂肪代谢的影响,选用120只商品代健康雏鸡,按常规饲养管理规程,平均分成2组,一组笼养,另外一组放养。每个组5个重复,每个重复12只鸡。试验结果表明,饲养方式对藏鸡体重与日增重有显著影响,不论公鸡还是母鸡,笼养的体重与日增重都显著高于散养鸡(P<0.05)。笼养鸡的肌间脂肪、皮下脂肪、腹脂率、肌内脂肪含量均显著高于散养鸡(P<0.05)。 相似文献

拉萨白鸡是西藏培育的第一个良种蛋鸡品种，是以藏鸡为杂交母本，来航鸡为杂交父本进行杂交的。藏鸡血液占拉萨白鸡的1／4，来航鸡血液占拉萨白鸡的3／4，经过自繁定型，扩群提高，各项指标均达到品种群的标准。拉萨白鸡在不同的生长期，其饲养管理不同，现将拉萨白鸡不同生长期的饲养管理要点叙述如下。 相似文献

为了解低海拔饲养条件下藏鸡体尺性状和肉用性能以及它们之间的关系,笔者对泰州地区饲养的13周龄藏鸡体尺性状和屠宰性能进行了测定,并进行相关分析。13周龄藏鸡活体质量平均为891.00±89.49 g,屠体率平均为87.82±1.73%,全净膛率平均为63.32±1.71%,胸肌率平均为18.75±2.25%,腿肌率平均为26.60±2.52%。结果表明,低海拔地区饲养的藏鸡屠体率和全净膛率分别在85%和60%以上,肉用性能良好。同时,藏鸡体尺性状和屠宰性能多数呈极显著相关,可通过体斜长、胫骨长、胫围和胸宽的指标对低海拔地区藏鸡屠宰性能进行预测。 相似文献

<正>藏鸡是分布于我国西藏地区人工选择程度较低的地方特有的原始小型鸡种,属于肉蛋兼用型品种。作为我国特有的珍稀地方优良品种,藏鸡对高原气候具有良好的适应性,且抗病力强、肉质鲜美、营养价值高,是高原上开发绿色禽类食品潜在的素材。然而,藏鸡生长速度慢、开产时间晚、产蛋率低以及饲养管理不科学等因素严重制约了藏鸡产业的发展。因此,对藏鸡的种质特性、健康养殖技术进行介绍,以期为藏鸡资源的开发利用提供参考。 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

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
