Embodiment 1
[0019] (a) Provenance selection: use non-injury trapping method to capture breeding turtles in the wild, and select sexually mature individuals that can reproduce. It is required that the female turtle weighs more than 300g (this example chooses between 300~500g), and the male turtle weighs more than 400g (This embodiment selects between 400~500g), strong body, sensitive movement, bright eyes, no sickness, no deformity, tail and limbs intact, no damage to the epidermis, carapace, and abdomen, and no ulceration as species. Turtles; male and female sex identification is based on the position of the vent. When the tail is straightened outward along the midline of the plastron, the vent of the female turtle does not exceed the rear edge of the carapace, and the vent of the male turtle exceeds the rear edge of the carapace.
[0020] (b) Domestication before mating: the ratites are wild and have obvious stress reactions at the beginning of domestication. They generally refuse to eat ...

Abstract
The invention discloses an artificial pairing and breeding method of platysternon megacephalum. The method comprises the steps of: provenance selection, domestication before pairing, setting of a breeding pool, pairing and breeding, collection and incubation of eggs and the like. The method takes full account of the ecological and biological characteristics of platysternon megacephalum, including ethological characteristics, diet characteristics, habitat characteristics, breeding ecological characteristics and the like. The method can effectively solve the major problems in the current artificial pairing and breeding of platysternon megacephalum, including the problems in seed selection, pairing, selection of pairing time, sex ratio, density, bait, setting of breeding and incubation environment and the like; the occurrence of impairment and death in the breeding mating process is obviously reduced, the egg laying rate of female platysternon megacephalum and the incubation rate of eggs are obviously increased, artificial efficient breeding of platysternon megacephalum is realized, healthy platysternon megacephalum seedlings are obtained, and a technical support is provided for expanding the breeding population of platysternon megacephalum, promoting species protection and developing large-scale breeding; and the method requires little human input, has low cost, is easy to operate, and is favorable for popularizing the artificial breeding of platysternon megacephalum.
Description
Technical field: [0001] The invention belongs to the field of artificial domestication and breeding of wild animals, and in particular relates to an artificial mating breeding method for ratites. Background technique: [0002] The flat-breasted turtle (Platysternon megacephalum) is a rare economical freshwater turtle native to Asia. It is distributed in South China, East China and Southwest China, as well as Hong Kong in China. Compared with common freshwater turtles, flat-breasted turtles like cool water environments, are fierce and aggressive, and have strong territorial behavior. [0003] The meat of the flat-breasted turtle is delicious, has important food and medicinal value, and has a high market economic value. Therefore, it has been overhunted and traded for a long time, and wild resources have declined sharply, making the flat-breasted turtle an endangered species. In response to market demand, the artificial domestication and breeding of ratites can not only effec...
