随着当前国家畜禽业的蓬勃发展,特别是规模化养殖的不断进步,畜禽养殖业的污染问题日益突出,环境保护已成为新时期畜禽养殖业发展不得不面对的问题。而传统畜禽养殖业不仅容易引起水源污染、大气污染、土地污染,还会因人畜共患病的污染带来巨大的社会问题。鉴于此,本文总结分析了畜禽养殖业带来的主要污染源、产生污染的原因,并针对治理畜禽养殖业带来的污染提出相应对策,以期有效解决环境污染问题,推动畜禽养殖业的可持续发展。  相似文献

近年来,随着国家政策对畜禽养殖业扶持力度不断加大,畜禽规模化、标准化的养殖场规模不断扩大,畜禽养殖业得到了较快发展,畜禽养殖业已成为农村经济新的增长点和支柱性产业之一.然而,在畜禽养殖业不断壮大的同时,畜禽的粪便及污水排放量也随之增加,部分规模化畜禽饲养产生的大量粪尿随处堆积、污水任意排放,养殖废弃物未能得到及时处理和综合利用,严重影响了人们的生产生活环境,养殖污染已引起了社会的广泛关注.养殖污染治理日益突出问题亟待解决,综合治理养殖污染,对于改善农村环境卫生,实现畜禽养殖可持续发展具有重要意义.  相似文献

Heartworm in dogs in Canada in 1984   总被引:4,自引:4,他引:0       下载免费PDF全文
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.

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.

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
