GENETICAL STUDIES ON ANIMAL RESOURCES IN LAOS

(1)1997年12月8日至1998年1月8日，对老挝本地家畜及其近缘野生动物进行了形态和遗传学调查。本次调查特别关注当地家畜及其相关野生动物，如牛(Gaur)、猪(野猪)、山羊、鸡(红色丛林家禽)、鸭子、老鼠等的血液、头骨、毛发和其他组织样本的采集。样本数完全如下；当地牛138头，水牛55头，本地猪78头，野猪头骨2头和组织1头，本地山羊50头，小鼠13只，大鼠15只，本地鸡112只(蛋49只)，红色丛林鸡8只，本地鸭子56只。(3)老挝对大部分血液和组织样本，特别是山羊、猪、牛和水牛进行了分析，用电泳法检测遗传变异，并用血细胞样本提取DNA。(4)已编制了当地牛的身体测量数据，编制了毛色、羽色、角形、耳朵、乳头等外部可检测性状的遗传变异数据。

(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.
