摘要
黑琴鸡 Lyrurus tetrix baicalensis(Lorenz)是重要的狩猎鸟类之一;雄鸟体几纯黑。并带有蓝绿色金属光泽。尾羽呈古琴状,形态奇丽,故又有观尝价值,为国家二类保护动物。关于它的生态习性问题。国内、外曾有过观察和报导。如等(1952),(1960),,郑作新等(1963、1978),白逎擅等(1965)及高中信(1975)等。但某些环节的资料不足或尚缺,又鉴于该种经济鸟类。由于其栖息地屡遭破坏,加上乱捕滥猎,其数量日趋减少。为进一步摸清它的分布数量现状,给今后对其保护、利用和进行人工饲养等提供理论依据,同时也为填补国内。
The present paper consists of the following items: 1.The black grouse(Lyrurus tetrix baicalensis)distributes at about 43—5o N,and 120—126 E..The average of population den- sity of the grouse is 0.5/1 ha in the breeding period,at Hungh- uaerji region. 2.Proposal display starts in early April at Hunghuaerji region,and it is lasts about two monthes.The nests were located on the ground in a thick grass under Scotch Pine.Only one clu- tch is laid every year.Egg number of clutch averages 9(8—10) eggs.Laying one egg lasts for 45—50 minutes.The grouse has a habit of replenishing egg.After last egg is laid,the female st- arts to incubate at once.It lasts for 26—27 days.24 th day of the incubation,the female stayed in its nest whole day.Young grouse have to spend 4—6 hours for hatching.The percentage of hatching (3broods)is 100%.Breeding force is 4.5 each individual per year. 3.The content of egg-white protein accounts for 13.6%; The rude fat content is 28.3gms/100gms;Cholesterol is 15.26mg/ 100mg;Lecithin content is 12.6gms/100gms in the yolk.The pol- yacrylamide gel electrophretic pattern of the egg protein of the grouse consists of ovomacroglobulin,conalbumin,globulin,evo- mucoid,avvalbumin and prealbumin.The egg-white protein con- sists of 16 kinds of amino acid,and the content of Glu,Asp,Leu, Lysand Set of them is more than the others.
