[ Objective] In order to study incubation conditions of Tibetan chickens in low altitude areas. [ Method] Eggs of Tibetan chicken were transported to low altitude areas in highland areas for artificial hatching. [ Results] The results showed that the average hatching rate of fertilized eggs was 85.33% ; the average healthy chick rate was 91.77 % ; the average primary body mass was 31.2l g. Hatching rate of eggs in group 2 was the highest, which reached 90.52%, the aver- age egg mass was 43.25 g and the average egg shape index was 1.32. Hatching rate of eggs in group 2 was 13.11% and 2.47% higher than that in group 1 and group 3 respectively, which was 5.19% higher than the average value. Hatching rate and healthy chick rate of eggs in group 2 also showed the same trend. [ Conclusion] High hatching effect could be obtained under the better hatching condition in low altitude areas in highland areas. 展开更多
