Abstract:There are 5 species of snow cocks in the world and 3 species in Xinjiang, i. e., Tetraogallus tibetanus, Tetraogallus himalayrnsis and Tetraogallus altainens. Tetraogallus himalayrnsis inhabits extensively in the Tianshan Mountain, and belongs to the protected birds in class B in Chin. At present, the reports about the successful domestication, raising and reproduction of snow cocks are less. In order to domesticate, raise and reproduce the snow cocks for bringing benefit to mankind, some scientists of Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences have carried out 2 research projects about snow cocks since 1993. A preliminary success about raising and reproducing the snow cocks has been achieved after the experiments of the artificial domestication, reproduction and incubation, which provides a basis for raising snow cocks in large scale in the future. The preliminary research results about the artificial raising and reproduction of Tetraogallus himalayrnsis are reported in the paper. The main results are as follows: (1) The Tetraogallus himalayrnsis inhabits in the snow-covered mountainous zones, meadow zones and alpine grasslands in an elevation range of 25006000 m, and can be raised in the regions in an elevation range of 15002000 m after they are artificially domesticated. (2) The reproduction period of the Tetraogallus himalayrnsis is for 3 months, and each Tetraogallus himalayrnsis can lay 3040 eggs. Under the fine raising and management conditions, each Tetraogallus himalayrnsis can lay 4060 gees. (3) After the domestication experiment, it is found that the incubation temperature of the breeding eggs of Tetraogallus himalayrnsis is 12℃ lower than that of the domestic fowls, and the eggs can be incubated under the constant temperature. The temperature of the egg surface can be increased to 30℃ when the eggs are cool, then the power supply can be cut off for a short time, and the temperature of the egg shells should be maintained at about 25℃. The suitable incubation humidity is 58%, and it can be increased to 70% when the egg shells are broken in a short time. (4) The practice reveals that the chicks of Tetraogallus himalayrnsis can grow rapidly under the fine artificial raising and management conditions and the suitable environment, the average daily increasing weight of the chicks in ages of 48 weeks can be up to 1015g at Bogda Tetraogallus himalayrnsis Farm, and the weight of 6-month-aged Tetraogallus himalayrnsis can be over 2.7 kg.
