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.

本研究对越南动物资源进行遗传分析，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。调查动物及样本数为：牛（101只）、水牛（102只）、山羊（83只）、绵羊（34只）、鸭（219只）、土鸡（81只）、麝鼠（28只）、小鼠（1只）。结果（1）改良品种对越南本地动物的影响：在所有调查地区，纯本地牛（越南黄牛）的数量迅速减少。与Sindy或Ongole杂交的数量增加。山区只饲养纯土种山羊，平原地区以改良品种代替土种山羊。小型斗鸡是非常罕见的，我们在我们的调查中认识到不到15只鸡。2）形态学和电泳位点及血型分析（部分结果）在对本地鸡的电泳分析中，Akp、Akp-2、Tf、Pa和Es 5个位点表现出多态性，其余4个位点表现为单态性。在血型上，越南山羊的B系统与我们在亚洲其它国家调查的鸡一样具有很高的多态性，越南山羊的Tf B和C基因频率较高，可能属于印度山羊的一个类型，越南绵羊的Tf C和HbA基因频率较高。
