Abstract:

By simulating the natural incubation environment of the Common Moorhen（Gallinula chloropus）， including the regulation of temperature and humidity，and providing appropriate rearing and care of the hatchlings， this study aimed to explore artificial incubation and chick-rearing methods for the species. The results demonstrated that the artificial incubation period of the Common Moorhen ranged from 18 to 20 days，with the majority hatching at 19 days. The average weight and dimensions of Common Moorhen eggs were（18.33±1.00）g，（42.14±0.79）mm × （29.24±0.64）mm respectively，with an egg shape index of（1.45±0.03）. Under+incubation conditions of 37.8℃ temperature and 55% relative humidity，the hatching rate reached 88.89% . Fertilized Common Moorhen eggs exhibited varying degrees of weight loss during incubation，which exhibited a linear relationship with incubation days， as described by the linear regression equation y=- 0.1133x + 18.339（R²=0.998）. The growth and development of Common Moorhen chicks conforms to the Logistic，Gomertz，and Von Bertalanffy growth curve models，with the curve fitting degrees R² being 0.981，0.963，and 0.955，respectively. Among these，the Logistic model exhibited the highest fitting degree. The Logistic equation is y=172.68（/ 1+21.587e-0.132609t）with a curve fit of R²=0.981. The inflection point mass A/2 was 86.34 g，and the inflection point age lnB/k was 23.16 days. These findings provide important theoretical foundation and practical insights for guiding the artificial incubation and chick rearing management of Common Moorhens，thus offering practical technical support for improving their breeding efficiency.
