红河州建水县地处低纬度、高海拔的喀斯特地区,是国家“十三五”可持续发展实验区之一。近年来,以种草、养羊为模式的畜牧业迅速发展,成为农户增收的有效途径,但在发展过程中,土地利用率低、养殖效益低下等问题也日益凸显,因此,为了提高效益,促进生态畜牧业的发展,在建水县面甸镇五里冲建设了奶山羊种草养殖现代高效农业示范园区,该园区的建设模式对于缓解当地的能源问题、保护生态环境具有重大而深远的意义,并为今后推广种草养畜技术提供技术和理论指导。 相似文献

中国鹅养殖业历史悠久,鹅品种资源丰富,近年来,养鹅业发展迅速,我国的鹅肉制品产量、养鹅数量、羽绒制品产量在我国畜牧业经济中占重要地位,在世界也排名首列。鹅饲养管理技术、品种不断改进,推动规模化养殖,集约化程度不断提升,推动了养鹅经济的迅速发展。鹅是草食性家禽,食性比较杂,种草养鹅是一种节粮型畜牧养殖项目,降低了养殖成本,增加了养殖户的经济效益。并且种草养鹅的鹅肉产品无药物残留,无污染,符合绿色消费需求,顺应我国环保经济的发展趋势。本文研究对比全精料饲养模式、传统放牧饲养模式以及最新种草养鹅模式下的人工牧草配比精饲料的不同模式饲养效果,结果显示,人工种草配比精饲料养殖鹅75日龄体重3.35kg/只,95日龄出栏体重3.97kg。相比全精料饲养模式、传统养殖模式,人工种草配比精饲料养殖的存活率高,养殖成本低,经济效益更高。 相似文献

在国内首创稻田养殖的江苏农民,根据市场需求的变化不断调整创新出一些新的种养模式。 传统的“稻田养鱼”逐步发展为“稻田养虾蟹”、“种草养殖”乃至“提水养殖”。养殖品种扩大到罗氏沼虾、牛蛙、甲鱼、龙虾、黑鱼等10多个。特别是该省粮食市场全面放开后,许多农民不再拘泥于单纯的种稻,而是自主创新,在稻田里种植水生经济作物如慈姑、藕、茭白等,形成了各种立体种养模式。 在单纯种粮比较效益低下的情况下,集种植、养殖 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

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.

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
