12014-2019年广东省蛋鸡市场发展情况2013年“H7N9”事件的冲击,使2014年全国范围的产蛋鸡存栏下降。年初受疫情影响“,市场谈禽色变”,蛋价一路狂跌。疫情影响退却后,蛋鸡养殖行情“面目全非”,蛋鸡存栏一度降低至往年的近7成,鸡蛋产量下降5%左右,供应的持续偏紧,导致鸡蛋价格大幅上涨并维持在历史高位水平。和2013年相比,2014全年蛋鸡产业生产效益良好,商品蛋鸡养殖利润超过30元/只,并且鸡蛋和淘汰鸡价格处于历史高水平,蛋鸡市场扭亏为盈,创近3年新高,蛋鸡业成为畜牧行业中效益最好的一个产业。  相似文献

2014年我国蛋鸡产业状况及发展趋势   总被引:2,自引:0,他引:2  
我国蛋鸡产业养殖规模和鸡蛋产量长期稳居世界第一,但小规模养殖占主体的生产方式使鸡蛋价格频繁出现波动,对生产和消费造成一定冲击。2014年我国蛋鸡存栏下降,鸡蛋供求处于紧平衡状态,导致鸡蛋价格大幅上涨。本文从生产、市场、成本、收益4个方面深入分析了这一热点问题,探讨了影响鸡蛋价格的主要因素。预计2015年蛋鸡存栏量将处于增长期,鸡蛋价格会走低,养殖效益低于2014年。最后,为继续推动我国蛋鸡产业发展,笔者提出了6点发展建议。  相似文献

<正>我国作为世界鸡蛋生产和消费大国,鸡蛋产量长期处于世界首位。然而,蛋鸡养殖仍然以小群体大规模的生产模式为主,饲养条件较简陋,生产水平普遍不高,环境污染和传染病威胁严重。面对我国蛋鸡生产技术水平总体不高的现状,为解决我国蛋鸡产  相似文献

正河北省曲周县是养鸡大县,2013年蛋鸡存栏达799.3万只,鸡蛋产量为10.29万吨,蛋鸡存栏和鸡蛋产量位居邯郸市第三,但是与省内一些蛋鸡养殖先进市县相比,养殖和管理水平亟待提高。一、河北省曲周县蛋鸡养殖业中存在的问题1.规模化程度低,养殖设施设备落后虽然曲周县是养鸡大县,蛋鸡存栏和鸡蛋产量位居邯郸市第三,但养鸡规模化程度低,生产水平低,70%的农户存栏在500~2000只,5000只以上的农户不足20%,万只以上的规模养鸡场仅为1%左右。由于经济条件的限制,只有少数养殖  相似文献

2008年,我国的蛋鸡生产可以说是在高成本低效益下运行的。山东的蛋鸡生产也是如此。2008年山东的蛋鸡生产,上半年价格低,6月末价格上涨,养殖效益好转。10月份受“三聚氰胺”事件影响,鸡蛋价格下跌,蛋鸡饲养处在盈亏平衡状态。  相似文献

近几年来,鸡蛋价格持续下跌,养鸡效益低下,部分养殖户悲观失望,认为蛋鸡养殖没“戏”了,纷纷退出了这一行业。确实,由于市场调节,目前,我国蛋鸡养殖已由暴利时期转向微利经营,在处于低谷时,养殖户甚至赔本饲养,养殖积极性大大降,氐。蛋鸡养殖是否还有利可赚?笔队为答案是肯定的。只要在养殖过程中大力挖掘生产潜力,就一定能够提高经济效益,蛋鸡养殖肯定有“戏”。  相似文献

2005年1~8月份,国内蛋鸡市场总体波动仍呈现“后禽流感”时期特点,“节日效应”明显。主产区鸡蛋价格波动与去年同期相似。河北、山东、河南、江苏四大鸡蛋主产省1~7月份平均蛋价5.63元/千克。较去年同期的5.14元/千克上涨0.49元/千克。1~8月份主产区养殖户盈利在11.13元/只左右,远高于去年同期的3.61元/只左右,养殖效益处于正常略高水平,养殖户补栏积极性较高,对生产有利。1~8月份国际鸡蛋价格持续下跌,与国内鸡蛋主产区之间的价差逐渐缩小,1~8月份平均价差为9.67元/千克,出口潜力巨大。  相似文献

Heartworm in dogs in Canada in 1983   总被引:6,自引:6,他引:0       下载免费PDF全文
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.

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
