查询词典 Bombay duck

In order to diagnose disease caused by muscovy duck parvovirus rapidly and accurately, and at same time, further study the taxonomic relationship between muscovy duck parivovirus and goose parvovirus, two pairs of PCR primers (LHMP1/LHMP2 and LHGP1/LHGP2) were designed respectively base on complete nucleotide sequences of Muscovy duck and Goose parvoviruses registered in the GenBank, The LHMP1 for the upper one and the LHMP2 for the lower one, corresponding to the specific nucleotides sequence 454-472 and 1173-1155 respectively in MDPV, and the LHGP1 for the the upper one and the LHGP2 for the lower one, corresponding to the specific nucleotides sequence 454-472 and 1173-1155 respectively in GPV.

为了能快速、准确地对番鸭细小病毒病进行诊断，同时为了能进一步弄清番鸭细小病毒与鹅细小病毒在分类学上是一种怎样的关系，比较GenBank中MDPV和GPV的基因序列，针对这两种病毒左阅读框编码非结构蛋白基因序列的相同区段，分别构建两对PCR引物。第一对引物LHMP1／LHMP2是根据MDPV的基因序列设计的，上游引物针对MDPV基因序列的454～472；下游引物针对基因序列的1173～1155，为19个碱基，扩增跨幅为719bp。

Pythonic编程风格，通过观查一个对象的方法或属性特征，而不是一个对象和某种类型的显式关系来决定一个对象的类型（"如果一个东西像鸭子一样走路，像鸭子一样叫，那么它一定就是鸭子。"）。

Test According to marine experts, rhino feetis a non-polluting shallow water, where the shallow tidal flats have a tremendous wealth of fish, shrimp, crabs and shellfish, algae and other micro-organisms, which reared duck grazing provides a natural high-quality food,sea duck is the duck reared with grazing produced, eggs rich in calcium, iodine, zinc, selenium, iron, magnesium, potassium and other trace elements and vitamins needed for a variety of human , amino acids and rich in lecithin, is an ideal food.

据海洋专家检测鉴定，犀牛脚三娘湾是一片无污染的浅海，那里的浅海滩涂上有着极为丰富的鱼、虾、蟹及贝类、藻类等微生物，这为放牧饲养的蛋鸭提供了天然优质的食料，三娘湾海鸭蛋就是这一带放牧饲养的蛋鸭所产，蛋中富含钙、碘、锌、硒、铁、镁、钾等多种微量元素和多种人体所需的维生素、氨基酸及丰富的卵磷脂，是理想的绿色食品。

The results showed that the average heterozygosity was higher in 9 populations,the lowest is Jinding, the highest is San sheldrake, which ranged from 0.5137~0.6055. The average heterozygosity of 9 duck populations was 0.5523, which reflected the rich diversity. Considerable breed differentiation was observed and 25.65% of the total genetic variation came from breed differences, this result affirmed each breed was of own genetic diversity. The DA genetic distances suggested the longer differentiation existed between those breeds. The domestic duck breeds in East China were clustered into four groups based on the NJ clustering, the clustering results had some relationship with the distributions and economic utilizations of these duck breeds.

结果表明：9个品种的平均杂合度都较高，最低的为金定鸭，最高的为山麻鸭，杂合度范围为0.5137～0.6055，群体平均杂合度为0.5523，反映了各鸭种的杂合度都较高，遗传多样性丰富；华东区各鸭种间存在较大的遗传分化，25.65%的遗传变异来源于品种间的差异，更进一步反映了各品种具有本品种特征特性的多样性；通过计算DA遗传距离发现各群体的遗传距离较远，分化时间较长；NJ聚类结果将华东区家鸭资源聚为4类，NJ的聚类结果分析与几个鸭品种的地域分布和经济用途有一定关系。

This duck is a cross between a wild duck and an ordinary duck.

这种鸭子是野鸭和普通鸭子的混种。
