GENETICAL STUDIES ON ANIMAL RESOURCES IN LAOS

(1) 1997年12月8日至1998年1月8日对老挝本土家畜及其相关野生动物进行了形态和遗传学调查。调查重点收集了本地家畜及其相关野生动物的血液、头骨、毛发和其他组织样本，如牛(野牛)、猪(野猪)、山羊、鸡(红原鸡)、鸭、小鼠、 （2）可从万象（含本市）、川圹、波里坎塞、占巴塞四个省采集血液和组织样本。样品数量总计如下：本土牛：138头，水牛：55头，本土猪：78头，野猪：头骨2个和组织1份，本土山羊：50头，小鼠：13头，大鼠：15头，本土鸡：112头（鸡蛋：49头），红原鸡：8头，本土鸭：56头。（3）大部分血液和组织样本，特别是在老挝对山羊、猪、牛和水牛进行了分析，通过电泳的方法检测遗传变异，并用血细胞样本提取DNA。（4）已经编制了本地牛、水牛和山羊的身体测量数据。（5）还编制了外部可检测性状的遗传变异数据，例如毛色、羽毛颜色、角的形状、耳朵、乳头。

(1) Morphological and genetical survey was conducted with native domestic and their related wild animals in Laos from December 8 in 1997 to January 8 in 1998. The survey was done with special interest on collection of samples of blood, skull bones, hairs, and other tissues of native domestic animals and their related wild forms, such as cattle (gaurs), pigs (wild boars), goats, chickens (red jungle fowls), ducks, mice, etc.(2) Blood and tissue samples could be collected from four provinces, that is, Vientine (included the city), Xiengkhoang, Borikhamsai and Champasak. Numbers of sammples were totally as follows ; native cattle : 138, water buffaloes : 55, native pigs : 78, wild boars : skull 2 and tissue 1, native goats : 50, mice : 13, rat : 15, native chickens : 112 (eggs : 49), red jungle fowl : 8, native ducks : 56.(3) Most of blood and tissue samples, especially goats, pigs, cattle and water bufffaloes, were analized in Laos in order to detect genetic variants by the method of electrophoresis, and the blood cell samples were used to extract DNAs from them.(4) Data of body-measurements were already compiled for the native cattle, water bufaloes and goats.(5) Data of genetic variations in externally detectable characters, such as coat-color, feather color, shape of horns, ears, teats were also compiled.
