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学和遗传学调查。这项调查特别关注采集本地家畜及其相关野生形式的血液、头骨、毛发和其他组织样本，如牛（高卢人）、猪（野猪）、山羊、鸡（红原鸡）、鸭、小鼠等。(2)血液和组织样本可从四个省收集，即万象（包括该市）、川宽、博里坎赛和占巴塞。共采集标本138份，水牛55份，猪78份，野猪头骨2份，组织1份，山羊50份，小鼠13份，大鼠15份，鸡112份（蛋49枚），红原鸡8份，鸭56份。(3)老挝对山羊、猪、牛和水牛等动物的血液和组织样本进行了电泳分析，并提取了血细胞DNA。(4)已经编制了本地牛、水牛和山羊的身体测量数据。(5)对毛色、羽色、角形、耳形、乳头等外部可检测性状的遗传变异进行了统计分析。

(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.
