2021年肉鸡产业发展形势及2022年展望

2021年我国鸡肉生产继续保持增长,鸡肉产量仅次于美国,位居世界第二位.随着生猪产能恢复,猪肉价格回落到正常水平,鸡肉消费对猪肉消费的替代效应减弱,导致鸡肉消费增速放缓,产能仍然过剩,产业总体收益偏低.根据肉鸡生产监测数据测算,2021年全国肉鸡出栏118.3亿只,同比增长7.4％;鸡肉产量1989.1万吨,同比增长7...

2020年肉牛产业发展形势与2021年展望

2020年,肉牛产业发展总体平稳,养殖户扩产积极性较高,牛肉产量稳定增长,消费增长较快,拉动牛肉进口大幅增加,国内供需总体呈偏紧态势。国家统计局数据显示,2020年牛肉产量672万吨,同比增长0.8%。海关总署数据显示,牛肉进口增长27.7%。据农业农村部肉牛生产监测,2020年12月底,肉牛存栏同比增长7.2%,能繁母牛存栏同比增长8.2%;全国牛肉市场价格同比上涨14.9%,养殖保持较好收益。预计2021年,肉牛存栏稳中有增,牛肉产量保持稳定增长,牛肉价格继续高位运行。     

当前山东省肉鸡养殖行情分析和产业发展建议

正新冠肺炎疫情爆发前,山东省肉鸡产业正处于年度高点回落之后的盘整阶段。据国家统计局山东调查总队数据,2020年一季度我省家禽存栏7.9亿只,同比增长2.2%;禽肉产量91.2万吨,同比增长9.9%;其中肉鸡存栏3.8亿只,同比增加1.2%;鸡肉总产量为65.6万吨,同比增长17.2%。一季度活鸡出栏均价为9.28元/kg,同比减少9.29%,环比降低30.86%。     

新形势下肉鸡产业如何实现绿色发展

<正>近年来，我国肉鸡产业在曲折中不断发展壮大。2012年以后，由于速生鸡事件、H7N9流感疫情等因素影响，肉鸡产量一度下滑，到2017年我国肉鸡产量为1 160万吨，降幅为16.3%。但随着国家推行H7N9流感强制免疫，再加上2018年下半年国内“非洲猪瘟”疫情原因，生猪养殖规模大幅下降，致使鸡肉的需求增加，肉鸡养殖再度逆势增长，产业规模持续扩增。2021年全国肉鸡出栏118.3亿只，同比增长7.4%；鸡肉产量1 989.1万吨，同比增长7.9%。肉鸡产业呈现出新的特点：一是规模化养殖趋势显现。2011—2019年，     

2011年上半年我国肉鸡市场形势分析及展望

2011年上半年我国肉鸡生产保持稳定,肉鸡产品价格上涨,农户收益增加,肉鸡进口减少、出口增加,继续保持贸易顺差。国际市场美国鸡肉价格有涨有跌,出口减少。预计下半年我国肉鸡价格将稳中趋升;全球鸡肉产量、贸易量均增加。     

2013年世界鸡肉产量预测

一世界家禽生产增速大幅放缓据FAO预测,2013年世界禽肉产量预计达到1．064亿吨,但自2010年以来肉鸡生产增速大幅放缓,已从年增量4．5％降至今年的1．溉。其中,鸡肉产量占世界禽肉产量约88％。2013年世界鸡肉（包括肉鸡、散养鸡和屠宰的蛋鸡）总产量可能超过9300万吨。而据美国农业部估计,2013年单纯的肉鸡肉产量将达8460万吨左右,比2012年的8280万吨增长了2．2％（见表1）。     

我国优质鸡育种技术现状与创新方向探讨

我国人民素有“黄鸡”消费习惯。从20世纪90年代始,因经济水平的提高带动了消费的巨大增长,我国优质鸡生产进入了旺盛发展时期。1990年我国的肉鸡产量为258万吨,2000年增长为1159.2万吨;1990年共出栏优质肉鸡6亿只,2000年出栏达18亿只,每年优质鸡生产量以20%的速度递增。据FAO统计,2005年我国禽肉产量居世界第二,达1468.9万吨,占世界总产量8101.4万吨的18.13%;我国禽肉中鸡肉产量占69.09%,而优质肉鸡的生产数量已占白羽肉鸡生产数量60%左右。以江苏为例,1996年全省生产优质鸡0.5亿只,2005年全省优质鸡的生产已达4亿只左右。我国优质鸡产业迅猛发展的原因一方面是由于广阔的市场空间,另一方面则更得益于在育种方法、饲养技术等方面的长足进步,特别是近年来,优质鸡产业化生产格局已在一些地区初步形成。下面就我国优质鸡育种发展历史、水平、存在问题进行分析,并对未来的优质鸡育种技术创新方向进行探讨。

Heartworm in dogs in Canada in 1984

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.
