禽

About the size of a goldfinch, the bird had an alula, or bastard wing, that would have helped it stay aloft at slow speeds.

大小约一goldfinch ，禽流了阿卢拉，或王八翼，这将有助于它留在高举速度变慢。

Avian leukosis virus subgroup J was first isolated in 1989 and identified as a new subgroup of avian leukosis virus.

J亚群禽白血病病毒是1989年被分离、鉴定出的一个新的禽白血病病毒亚群，与其它ALV亚群比较，该亚群病毒的一个显著特点是其env基因非常独特。

The present study was undertaken to observe experimental myeloid leukosis induced with IMC_(10200) strain ALV-J which was isolated originally from a normal broiler breeder.

对分离自肉种鸡群亚临床感染的J亚群禽白血病病毒IMC10 2 0 0 株进行了实验感染诱发禽骨髓性白血病的病理学研究。

Avian Leukosis Virus Subgroup J is a new kind of retrovirus which infects meat-type chickens, ALV-J was first reported as a new subgroup of ALV by Payne in 1991. It seriously influnenced the development of broilers industry.

J亚群禽白血病病毒(Subgroup J of Avian Leukosis Virus，ALV-J)是上世纪80年代末从肉用型鸡中分离鉴定出来的禽白血病病毒(Avian Leukosis Virus， ALV)新的亚群，严重影响了肉鸡业的健康发展。

To determine the extent of avian leukosis virus infection in China in 2009, 178 suspected ALV samples were collected from 39 chicken farms in eight provinces and examined by polymerase chain reaction with ALV-A, ALV-B and ALV-J gene specific primers.

为了解自2009年年初以来国内一些地区禽白血病流行情况及流行毒株的分子特征，我们从湖北、黑龙江、山东、辽宁、吉林、广东、宁夏、安徽8个省区39个鸡场采集疑似禽白血病病料样品178份，用ALV-A、ALV-B和ALV-J特异性引物，通过PCR方法进行检测。

College of Animal Science and Veterinary Medicine,Shandong Agricultural University, Taian,Shandong , 271018, China Abstract:Avian leukosis virus Subgroup J is a retrovirus that infects meat-type chickens.

J亚群禽白血病病毒（Subgroup J of Avian leukosis virus，ALV-J）是90年代初由英国鉴定出来的禽白血病病毒新的亚群，主要引起肉鸡的骨髓瘤白血病。

An subgroup J avian leukosis virus,designated as SCAU-0901,was isolated and identified by histopathological observation,DF-1 cell culture,ELISA test,PCR and immunofluorescence assay specific to ALV-J from Mahuang broiler breeder suspected with ALV infection.

在组织病理学观察的基础上，经接种DF-1细胞系、ELISA抗原检测、聚合酶链式反应以及亚群特异性免疫荧光试验，从送检的疑似禽白血病感染的麻黄肉种鸡中分离并鉴定出1株J亚群禽白血病病毒，命名为SCAU-0901。

In Veneto, where flock density was highest, infection-control was also accomplished by means of depopulation of susceptible flocks through a ban on restocking and pre-emptive slaughter of flocks that were in the vicinities of or that had dangerous contacts with IPs.

在禽群密度最高的Veneto地区，规定凡属疫点附近或与疫点有密切往来的场所均严禁屯养活禽，所有交易禽类必须在出栏前宰杀。

It uses a methane station as the energy transfer center to promote clean production and resources recycling — the grains and straws are processed and turned into fodders for stock and poultry, whose manures are sent to make methane for village residents; the residue of the methane will be used as good organic fertilizers.

具体做法是：种植业生产的粮食和秸秆加工饲料，饲料供养殖业喂养蓄禽，蓄禽的粪便输送到沼气站发酵沼气，沼气供给农户使用，沼渣和沼液做为优质的有机肥再循环到种植业，通过这样的良性循环，形成了各行各业、相互依存、相互促进的有机生态链。

With the rapid development of poultry husbandry, a lot of poultry manure has become thesource of environment pollution and prohibited the stable development of poultry raise.

随着集约化养禽业迅猛的发展，大量的禽粪便造成环境污染，并成为阻碍禽养殖业持续稳定发展的重要因素。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
