specific Embodiment approach 1

[0021] The specific embodiment one, is used for the screening method of goose seedling, it comprises the following steps:

[0022] Step 1. Using a constant temperature incubator to hatch N breeding eggs into N goose seedlings; N is a positive integer;

[0023] Step 2. Screen out the unhatched eggs in step 1, and then perform step 3;

[0024] Step 3. Place all goose chicks hatched in step 1 in the weightlessness simulation device and simulate the weightlessness state in the weightlessness simulation device. The simulation time is t1, and then perform step 4;

[0025] Step 4: Stand still for t0, and then execute Step 5;

[0026] Step 5. After the time t0 of step 4, judge whether any goose seedlings have fallen or fainted. If the judgment result is yes, then the fallen or fainted goose seedlings are regarded as inferior goose seedlings, and step 12 is performed; If the judgment result is no, then perform step six;

[0027] Step 6. Use all goose chicks that have not fallen or f...

Abstract

The invention discloses a gosling screening method in a goose breeding process, relates to a waterfowl breeding technology, and aims to solve the problem of breeding resource waste caused by low gosling screening efficiency and poor screening accuracy in the current goose breeding process. According to the multi-stage progressive gosling screening method, the weightlessness and overweight states are simulated through early intervention, then the corresponding response of goslings is judged to serve as the screening condition, the screening efficiency is high, the screening accuracy is high, and therefore a large number of breeding resources are saved.

Description

technical field [0001] The invention relates to waterfowl breeding technology, in particular to the goose seedling screening technology. Background technique [0002] Goose belongs to poultry and is very popular among consumers in the market because of its delicious taste, firm meat and rich nutrition, and there are many kinds of derivative foods of goose. For example, it is very popular among people; [0003] According to the macro-classification, geese belong to the order of waterfowl, which are birds with water as their living environment. [0004] Like other waterfowl animals, geese reproduce by hatching eggs. The goslings after hatching are called goose seedlings. In the actual breeding process, due to some congenitally deficient goose seedlings, in order to ensure market demand, the gosling After the eggs are hatched, the goose seedlings obtained by the team should be screened. At present, the screening of goose seedlings is limited to the visual inspection and experi...
