specific Embodiment approach 1

[0017] Specific implementation mode 1: In this embodiment, the artificial incubation of the great bustard is divided into four periods: the early incubation period, the middle incubation period, the late incubation period and the hatching period; the first to 11th days of incubation are the early incubation period; the 12th to 17th incubation period Days is the middle stage of hatching; from the 17th day of incubation to when the embryo enters the air chamber is the late hatching stage, and when the embryo enters the air chamber until it is completely hatched is the hatching stage; the early stage of hatching, the middle stage of incubation and the late stage of hatching are carried out in the incubator, and the temperature of the incubator is 36-37.8 ℃, humidity 50%-60%; the hatching period is carried out in the hatching box, the temperature of the hatching box is 36-37 ℃, and the humidity is 60%-65%; the eggs are turned every 2 hours in the early stage of hatching and the midd...

specific Embodiment approach 2

[0024] Embodiment 2: The difference between this embodiment and Embodiment 1 is: the great bustard embryo can make a cry when it enters the air chamber. Others are the same as the first embodiment.

[0025] In this embodiment, the sound of the bustard embryo in the air chamber changes from weak to strong with time, and the sound is loud, and the rhythm of the active shell pecking sound is strong, indicating that the embryo is well developed, which is a normal phenomenon.

specific Embodiment approach 3

[0026] Embodiment 3: The difference between this embodiment and Embodiment 1 is that artificial midwifery is required when the call or pecking sound of a great bustard chick changes from strong to weak at the hatching stage. Others are the same as the first embodiment.

Abstract

An artificial incubation and brooding method for great bustard and feed for a nestling of the great bustard relates to the artificial incubation and brooding method for bird and the feed for nestlings which solves the problems of low hatching rate, low surviving rate, hard feeding, and frequently dying at an age of 7 to 15 days of the nestling of great bustard for the current artificial feeding. The artificial incubation for the great bustard is divided into four periods of incubation prophase, incubation metaphase, incubation anaphase and hatching period. The feed for the nestling of the great bustard consists of animal feed and plant feed. During the brooding process of the great bustard, the hatching temperature for a brooding box at the first day is 36 DEG C and is reduced by 1 DEG C every day with the increasing of the day age. The nestling with an age of 12 days is arranged in a brooding bed and the temperature of the brooding bed is 24 to 28 DEG C and is brooded in the outside after two months. The hatching rate of the artificial incubation method for the great bustard of the invention is 81.81 percent and the surviving rate of the brooding method for the great bustard is 88.8 percent, thus solving the problem that the nestling of the great bustard frequently dies at an age of 7 to 15 days. The feed for the nestling of the great bustard is designed aimed at the physiological characteristics of the nestling of the great bustard and has the advantages of abundant nutrition and improving the physical constitution of the nestling.

Description

technical field [0001] The invention relates to a method for artificial hatching and brooding of birds and a feed for chicks. Background technique [0002] The great bustard (Otis tarda) is a Class I key protected animal in China. It is designated as a VU species by IUCN and is a vulnerable species. It is designated as a V class by the Red Book of Birds in China and is a globally threatened species. Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The great bustard is not only one of the endangered grassland birds, but also an ecological indicator species of the grassland. There are 11 genera, 25 species and 30 subspecies of bustards. Great bustard belongs to Cruiformes (Cruiformes) Bustard family (Otidae), which is divided into two subspecies, namely the nominated subspecies (Otis tarda tarda) and the oriental subspecies. species (also known as the common subspecies Otis tarda dybowskii), the great bustard is also...
