5月中旬,中国家禽业协会在杭州召开全国集约化鸡场鸡粪处理与加工研讨会,现将会议小结简述如下: 一、妥善处理鸡类的迫切性: 集约化大中型养鸡企业的鸡粪问题,已经到了非解决不可的时候.近10多年来,我国集约化商品家禽业有了很大发展.现在禽蛋、禽肉供应充足,价格便宜,这对改善人民生活,巩固发展安定团结的大好形势,起了十分重要的作用。但与此同时,也出现了污染环境,自家污染问题,危害人、家禽健康和农牧渔业生产。由于我国发展集约化养鸡的时间不长,开始缺乏经验,资金短缺,尤其是认识  相似文献

目前,我国养猪业已从家庭户养和分散饲养发展到今天的集约化饲养.集约化养猪场与传统的饲养方式相比具有规模大、数量多、密度高、生产工艺先进等特点.通过党的改革开放政策的不断深入,我国养猪业取得了长足的发展,据不完全统计,除西藏外全国30个省,2001年1月到6月我国生猪的饲养头数达到4.46亿头.但是各种疾病特别是猪的腹泻病也越来越严重地制约着养猪业的进一步发展,它可以造成仔猪的死亡,成猪的掉膘,饲料报酬的降低,增加人工费和药费的开支等危害.根据发病原因,猪的腹泻病主要包括病毒性的、细菌性的、寄生虫性及营养性代谢因素引起的腹泻.现就集约化猪场上述几种常见的腹泻疾病发生的特点及防制对策进行概述.……  相似文献

近年来,我国集约化猪场发展迅猛,2004年我国集约化猪场提供的出栏猪约有1亿头,可占出栏总数的15%左右;专家预测,到2015年,也就是10年后,中国将每年出栏8亿头猪,其中约有50%以上来自集约化猪场,集约化猪场将占据主导地位。然而,也应该看到目前我国集约化猪场的生产水平很低,笔者从事集约化养猪生产多年,整理了一套适合我国集约化猪场的“健康快乐”生产方法,并在许多猪场获得了成功。  相似文献

Heartworm in dogs in Canada in 1985   总被引:3,自引:3,他引:0       下载免费PDF全文
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.

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
