乌鸡(Gallus gall usodomesticus)是我国特有的家禽品种,已有数百年的培育历史。由于其具有药用、食用和观赏用等价值,已为古今中外所重视,其经济价值要比普通鸡高出2～3倍以上。但由于其就巢性特别强,每产7～8枚卵即出现“就巢”行为,停止产卵,严重地影响乌鸡生产力。关于“通过克服就巢性来提高鸡的产卵力”问题,各地曾有过多种试验,但效果都不太理想。我们在进行乌鸡的引种、驯化和繁育研究过程中,分别在长春郊区福利大队乌鸡场(1982)和南京市药材公司乌鸡场(1984)先后用8种药物进行了“醒巢”试验,现报道于下。
Gallus gallus usodomesticus is a unique breed of poultry in China and has been cultivated for hundreds of years. Because of its value of medicinal, edible and ornamental use, it has been valued by ancient and modern Chinese and foreign countries, and its economic value is 2 to 3 times higher than that of ordinary chickens. However, due to its particularly strong nesting, each egg produces 7 to 8 eggs, which means that the “nesting” behavior will stop the spawning and seriously affect the productivity of the black-bone chicken. Regarding the issue of “raising the chicken’s egg production capacity by overcoming the nesting nature”, various experiments have been conducted in various places, but the results have been less than satisfactory. During the study of introduction, domestication, and breeding of black-bone chickens, we used the “awake nest” test with eight drugs in Wuchang Farm (1982) in the Welfare Brigade of Changchun Suburbs (1982) and Wuji Farm (1984) in Nanjing Medical Materials Company respectively.
