麻鸭

By using the Neighbor-joining method, a dendrogram was obtained based on genetic distances. The bootstrap values were evaluated for each crunode of the dendrogram by means of bootstrap test. The results showed that the mean heterozygosity of the whole native egg-typing duck breeds population was lower than those of native chicken breeds and goose breeds, suggesting that the genetic diversity in those duck breeds population is relativly rare and should be strengthened. The rank of the heterozygosity was consistent with that of the polymorphism information content. The results of the genetic distances between them indicated that the differentiation occurred long time ago. In the dendrogram, Weishan pocked, Youxian pocked, Huainan pocked, Guangxi pocked and Jingjiang pocked were classified into one goup, Chaohuand Enshi pocked were the second group, Liancheng white, Putian black, Jinding, Shanma, Sansui and Shaoxing were the flnra grong.

结果表明：我国所有蛋鸭品种全部群体的平均杂合度较低，其遗传多样性相对贫乏，各保种场要加强多样性的保护；各品种的平均多态信息含量的高低与群体平均杂合度的顺序完全一致；遗传距离的计算说明了13个品种的遗传距离较远，分化时间较长；13个地方蛋鸭品种被聚类为3个类，微山麻鸭、攸县麻鸭、淮南麻鸭、广西小麻鸭、荆江麻鸭聚为一类；巢湖鸭和恩施麻鸭聚为一类；福建省的鸭种连城白鸭、莆田黑鸭、金定鸭、山麻鸭与三穗鸭、绍兴鸭聚为一类。

The molecular basis for the virulence of this virus is still poorly understood. We characterized two H5N1 subtype viruses, A/mallard/Huadong/Y/2003 is nonpathogenic to mallard whereas A/mallard/Huadong/S/2005 is highly pathogenic to mallard.

我们对从野鸭分离到的H5N1 亚型禽流感病毒的生物学特性进行鉴定，其中A/mallard/Huadong/Y/2003是对麻鸭无致病性病毒，而 A/mallard/Huadong/S/2005是对麻鸭高致病性病毒。

The most important species over the period 1978-83 were Pintail (17% of the total W European population), Teal (12%), Shelduck (7%) and Wigeon (2%).

在1978年至1983年期间最重要的物种是针尾鸭（针尾鸭，占欧洲人口总数的17％），绿翅鸭（绿翅鸭12％），翘鼻麻鸭（赤赤，7％）和赤颈鸭（赤颈鸭，2％）。

By using microsatellite markers, the genetic structure of 9 domestic duck populations in East china, including Weishan sheldrake, Chaohu sheldrake, Shaoxing, Gaoyou, Dayu, Jinding, Liancheng white, Putian black and San sheldrake, was analyzed in this experiment.

本实验通过微卫星标记技术对我国华东地区9个家鸭资源群体（微山麻鸭、巢湖麻鸭、绍兴鸭、高邮鸭、大余鸭、金定鸭、连城白鸭、莆田黑鸭、山麻鸭）的遗传结构进行了评估。

The results show that : pig species include Large White, Landrace, Duroc pigs and swine; cattle varieties of Simmental, Shorthorn and Brahman cattle, of Jersey cattle; sheep varieties Boer goats; duck, duck varieties, Cherry Valley Duck, Shaoxing Duck; Chicken varieties are emerging sanhuang, Guangxi top soil chicken, Ma top emerging chicken, black plume bamboo silk chickens and other species.

研究结果表明：（1）猪的品种主要包括大白猪、长白猪、杜洛克猪和香猪；牛的品种有西门塔尔牛、短角牛、婆罗门牛、娟姗牛；羊的品种有波尔山羊；鸭的品种有北京鸭、樱桃谷肉鸭、绍兴麻鸭；鸡的品种有新兴三黄鸡、广西土顶鸡、新兴麻顶鸡、黑羽竹丝鸡等品种。

Duck IFN-γ gene was amplified from total RNA extracted directionally from ma duck splenocyte by reverse transcription-polymerase chain reaction, then was cloned and sequenced.

应用RT-PCR技术，直接从成年麻鸭脾淋巴细胞提取的总RNA中扩增出麻鸭γ-干扰素基因，并克隆、测序。

The single nucleotide polymorphism of growth hormone gene was investigated in various breeds of duck, including Beijing ducks, Xihu mallards, Jinding ducks, Shan Partridge ducks, Jingjiang ducks and Shaoxing ducks. The primers for intron 2 and 3 in GH gene were designed based on the database of duck genomic sequence and the SNPs were detected by PCR-SSCP method.

根据鸭生长激素基因内含子2、3的序列设计5对引物，利用PCR-SSCP方法对北京鸭、西湖野鸭、金定鸭、山麻鸭、荆江鸭、绍兴鸭等6个鸭品种进行了单核苷酸多态性分析，并检测其多态性。

So prohibiting human disturbance and stopping shallow water areas and grassland habitat destruction as well as recovering the original habitat are important measures to mitigate the conflicts between Ruddy Shelducks and local people.

取食的时候，雌性赤麻鸭的警戒水平随捉到其雄性配偶的距离的增加而显著增长，而雄性赤麻鸭的警戒水平并未随着到其雌性配偶的距离的改变而发生变化。

Ruddy shelducks are monogamous. They form and maintain the pair bond at wintering ground; individuals that form and maintain pair bond at this most stressful time might be thought to accrue some advantage that would be adaptive.

通过扫描取样在拉市海越冬的配对赤麻鸭（2000年1月到3月）的活动时间预算，我们发现在此越冬的配对赤麻鸭主要有5种类型的行为活动，即，取食、休息、理羽、饮水、和警戒。
