| 英文摘要: |
| With the rapid retreat of habitat, the species of green peafowl (Pavo muticus) has a sharply
declining and the negative population trends are projected to continue. As a supplementary measure for
in-situ conservation of the green peafowl, the establishment of artificial populations for reintroduction (or
release) through captive breeding has gradually gained recognition. Artificial hatching by machines is an
important way to establish artificial population of the green peafowl. Due to lack of genetic diversity, reproductive
fitness is affected, and the reproductive capacity and egg hatching ability of the green peafowl
are weak, resulting in low hatching rates. Based on this reality, in order to quickly establish and expand
the artificial population, the strategy of artificial hatching for the green peafowl was mainly explored, including
timely collection and processing of eggs, timely hatching, and fully flipping eggs. While fully utilizing
the current precious germplasm resources and exploring the optimal hatching temperature and humidity,
additional losses caused by improper operations during the artificial hatching process should be avoided
as much as possible to improve the hatching rate. |
