美国是世界上最大的肉鸡饲养、生产和消费国之一,世界肉鸡产业的发展变化通常以美国为代表,20世纪60年代以来,新品种与新技术的采用,使美国的肉鸡生产得到很大发展,出现产品过剩、市场竞争激烈的局面,这就需要协调肉鸡产业中各部门的利益关系,如屠宰加工与肉鸡饲养者之间、饲养者与孵化场之间、孵化场与种鸡场之间,都需要在价格和利益方面进行协调、统筹,这就出现了一体化经营的肉鸡公司。1970年美国有80家这样的大公司,到1990年只有40家,据2003年统计,专门从事肉鸡生产加工一条龙企业有35家,19家火鸡大公司,还有5家生产肉鸡和火鸡两种产品的公司。2003年美国鸡肉产量1485万吨,屠宰数为86.8亿只(2002年分别为1462万吨和87.1亿只)。2003年美国火鸡产量256.3万吨,屠宰2.684L只,稍低于2002年水平(分别为259.1万吨和2.71万只),  相似文献

肉鸡生产是美国乔治亚州的一项大产业。据乔治亚州农业部门的统计资料报道 ,1 998年本州共出栏肉鸡 1 2 1亿只 ,比 1 997年的 1 1 8亿只增长了 3 % ,创造了连续 1 5年来的最高纪录。乔治亚州肉鸡产量占全国的 1 5 %以上 ,在 1 998年的全国排行榜上雄居第一位。乔治亚州的肉鸡生产目前主要集中于北部地区 ,其出栏量约占全州的 70 %以上。该区的肉鸡产量仍将持续 ,但就发展前景来说 ,本州肉鸡产业增长点将主要集中于中部和南部地区 ,这是因为这些地区可供利用的土地较多、城市化进程较慢、农民们需要发展新的产业以及该地区为减少热应激而采…  相似文献

1美国肉鸡业美国养鸡的历史非常短促,根据有关的资料记载,美国最初的鸡是由西班牙探险家于1500年左右带到了美洲。到了十九世纪初期,随着市场需求的需要逐渐引进了一些中国和印度等国优秀的亚洲鸡种。在二十世纪美国开始采用大规模现代化商业式的养鸡以前,美国肉鸡业同样经过了从农民家庭养鸡、专业化养鸡到肉鸡产业一体化的过程。目前,美国的养鸡产业在世界上占领先地位,每周屠宰约1.2亿只肉鸡,这些肉鸡都是在由大公司控制的、像工厂一样的厂棚中,用现代自动化的方法饲养。全美国每年屠宰的约53亿肉鸡中,其中一半由8家大公司掌控。2马立克…  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.

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
