Genetical Studies on Animal Resources in Vietnam

本研究对越南的动物资源进行了遗传分析，以比较印度尼西亚、斯里兰卡、孟加拉国、尼泊尔、泰国、菲律宾和中国的结果。调查动物和样本数量()如下：牛(101)：水牛(102)：山羊(83)：绵羊(34)：鸭(219)：土鸡(81)：麝鼠(28)：老鼠(1)。结果1)改良品种对越南本地动物的影响。与辛迪、昂戈勒的杂交组合数量增加。纯种本地山羊只在山区饲养，在平坦地区饲养改良品种而不是本地品种。小型野鸡非常罕见，在我们的调查中，我们识别的鸡不到15只。2)形态、电泳位点数和血型(部分结果)。在地方鸡的电泳谱分析中，AKP、AKP-2、Tf、Pa和Es 5个座位是多态的，其余4个座位是单态的。在血型上，越南山羊的B系统与我们引进的其他亚洲国家的鸡具有很高的多态性。越南山羊TfB和C基因的频率很高，可能属于印度山羊的一个类型。越南绵羊的TfC和Hba基因的频率很高。

Present study was carried out for genetical analysis on Vietnamise animal resources to compare those results in Indonesia, Sri Lanka, Bangladesh, Nepal, Thailand, Philippin and China.1. Surveying animals and sample numbers () are follow :Cattle (101) : Water Buffalo (102) : Goat (83) : Sheep (34) : Duck (219) : Native chicken (81) : Musk shrew (28) : Mouse (1)2. Results1) Effects of improved breeds on native animals in Vietnam.Numbers of pure native cattle (Vietnam Yellow) was rapidly decresed in all areas surveyed. And numbers of crossbreds with Sindy or Ongole were increased. Pure native goat raised only in the mountain areas, and improved breed was raised instead of native breeds in the flat areas. Small type of game chicken was very rare and we recongnized less than 15 chickens during our survey. Mouse was not found in south Vietnam at all.2) Morphological and electrophoretic loci and blood groups (from a part of results).In electrophoretic analysis of native chicken, five loci, Akp, Akp-2, Tf, Pa and Es, were polymorphic, though other four loci were monomorphic. In blood groups, the B sytem were very polymorphic as same as the chickens which we investegated in other Asian countries.Vietnamise goats have high frequencies of TfB and C genes, and they may belong to a type of Indian goats.TfC and HbA genes of Vietnamise sheep were high in their frequency.
