近年来,随着我国养殖业产业结构的调整,水禽养殖不仅在南方得到稳定发展,在中原地区也取得了快速的发展,为促进农村养殖业的多元化、丰富市场产品供应和农民就业与致富发挥了重要作用。但是,以往我国水禽业主要在南方水资源丰富的地区发展,其它地区则相对较少,而且主要采用以农 相似文献

记者：你对中国肉鸭产业在水禽产业中的地位有什么评价？王志跃：我国养鸭历史悠久，肉鸭产业发展迅速，20世纪80年代以来，饲养量以年均5％以上的速度增长。肉鸭养殖量大，是水禽中饲养量最多的，2008年肉鸭出栏超过30亿只，占世界的70％。国内消费量大，在出栏的肉鸭中，出口量极小。我国肉鸭的品种特色明显，北京鸭可称为世界肉鸭之父， 相似文献

目前肉禽配合饲料占工业饲料比例 30％左右， 2000年工业饲料总量 7 200万 t比 1999年增长 8％，主要原因是由于鸭、鹅等工业饲料的快速增长。目前水禽养殖比例占肉禽养殖数量 18％左右，并逐年递增； 2000年水禽肉增长超过 12％；水禽养殖数量增长超过 6％；水禽肉消费地区也从南方沿海向北方扩展，分析认为，由于 2000年新建水禽深加工企业，必然大力发展水禽养殖， 2001年水禽配合饲料增长将大于 10％，原因如下：
1、南方沿海地区农户 2000年水禽获利稳定，深加工带动养殖水禽数量增长迅速。如正大在南京建立肉鸭加工场；上海赢赢肉鸭出口利润稳定； 2000年广西合浦建立最大肥鹅肝加工基地；四川鸭肉产量稳定增长 8％，居全国之首；带动了全国养殖水禽数量的发展。
2、目前工业水禽配合饲料占目前饲喂总饲料比例不足 35％，大部分养殖户自行配比水禽料，技术含量等远低于养鸡的水平，水禽工业饲料发展空间很大。
3、目前水禽配合饲料没有专业龙头企业，包括正大集团等大部分企业只是将肉鸡饲料场转产水禽饲料，专业化和技术水平等不高，研究技术和投入相对不足。
4、由于饲料玉米、小麦等原料上涨，猪、鸡等养殖获利减少；以及水禽主产区政府引导大力推广节粮畜牧业，促使农户发展鹅、牛、羊等节粮禽畜。
5、水禽养殖特点是杂食为主，能消化部分牧草以及水草等粗纤维。节约部分粮食，疫病少，便于农户管理等。
水禽主产区：上海、江苏、浙江、江西、安徽、福建、湖南、湖北、广东、四川等 10个省区，产量占全国 85％左右，年出栏 15亿只水禽产品。 相似文献

养鸭作为我国的特色产业和农村发展的支柱产业已有很悠久的历史,早在公元前500年,我国就有大群养鸭、食用鸭肉和鸭蛋的记载。进入20世纪80年代,养鸭业迅速发展,饲养量平均每年以5％～8％的速度递增。随着肉鸭产业快速发展,养鸭企业正向规模化、集约化转变,并逐步向生态型养殖小区建设过渡,小群体大规模,公司加农户的生产模式迅速扩大,大公司不断出现,产业化程度迅速提高,养鸭成功企业的先进规模化生产的饲养模式,正逐渐得以推广并应用,提升水禽养殖档次。 相似文献

我国水禽养殖历史悠久。近年来．规模化水禽养殖业的产生．使我国水禽业生产迅猛发展．成为世界上最大的水禽生产国。水禽的饲养量、产肉量、产蛋量和产绒量居世界第一位。规模化水禽养殖业的发展在解决了水禽产品供给和带动农村经济发展的同时．也带来了日益严重的污染问题。减少水禽养殖过程中产生的污染．是一个刻不容缓的大问题。各养殖场、户应着重从以下几个方面做起： 相似文献

随着我国市场经济的发展,养殖业生产企业的经济效益已经随市场供求关系发生了明显的变化.畜产品必须以流通为前提,只有存在消费市场,养殖业才可持续发展,我国南方的养鸭业也是如此.鸭子养殖生产的增长速度,走上了一条自主经营、自负盈亏的道路.在买方市场形成的今天,如何进一步开拓鸭子的消费市场,是亟待解决的问题. 相似文献

我省集约化水禽养殖业始于20世纪80年代,由于水禽的抗病能力强,发病率低,水禽产品的营养学上低脂肪、低胆固醇、高蛋白特性,符合了广大消费者的需要,加之我省水禽业的得天独厚的品种资源、劳动力资源及一定水平的家禽生产和技术优势,使我省水禽养殖业在近年得到了迅速发展,尤其是集约化、规模化的水禽养殖企业不断增多,水禽养殖的效益不断提高。但是,与此同时,水禽疾病也开始逐渐增多,由于水禽疾病所造成的损失也逐渐增大,水禽疾病逐渐成为水禽养殖业发展的障碍。为了有效地控制疾病的流行,保障水禽养殖业的健康发展,我们对我省的水禽疾病的… 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 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 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 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
