Problems solved by technology

But limited to the current hatching technology, the hatching cycle of gray geese is usually more than 30 days. The long hatching cycle reduces the economic benefits of hatching, and the hatching rate is also low, only about 80%. Shortening the hatching cycle and increasing the hatching rate are the key to improving An important means of artificial breeding benefits, and it is also a problem that needs to be solved urgently

Embodiment 1

[0030] A high-quality hatching method for gray geese, comprising the steps of:

[0031] (1) Egg treatment:

[0032] a. Soak gray goose eggs in an aqueous sodium hypochlorite solution with a concentration of 2-4% by mass for 15-25 minutes, then take them out and rinse them with clean water;

[0033] b. Put the washed eggs into a container filled with nutrient solution, control the pressure in the container to 1.2~1.4MPa, take it out after soaking for 10~15min, rinse with water and dry it for later use; the nutrient solution consists of the following parts by weight: Material composition: 1~2 parts of electrolytic multidimensional, 2~3 parts of compound amino acids, 0.5~1 parts of potassium iodide, 0.3~0.8 parts of sodium chloride, 0.3~0.8 parts of calcium chloride, 0.4~0.6 parts of amino acid chelated iron, 0.1 ~0.3 parts of amino acid chelated manganese, 25~30 parts of water;

[0034] (2) Preparation of incubation medium:

[0035] a. Weigh the following substances by wei...

Abstract

The invention discloses a high-quality hatching method for greylag. The high-quality hatching method is characterized by comprising the first step of hatching egg processing, the second step of hatching medium preparing, the third step of hatching egg hatching and the hatching egg hatching out. According to the high-quality hatching method, scientific and reasonable fine management is carried out on hatching conditions of hatching eggs and conforms to the hatching egg hatching rule of the greylag, the hatching period is remarkably shortened, young greylag can be hatched out within 21-23 days, the hatchability is increased well and stabilized to be 95% or above, and the hatched young greylag has the advantages of being strong in physique, large in size and full of animal spirits.

Description

technical field [0001] The invention belongs to the field of breeding, and in particular relates to a method for hatching gray geese with high quality. Background technique [0002] Gray goose (scientific name: Anser anser): body length 70-90 cm, wingspan 147-182 cm, weight 2.5-4 kg, life span 17 years. Large and fat. The mouth and feet are flesh-colored, the upper body is taupe, and the lower body is white. When flying, the wings flap vigorously, and the frequency of wing flapping is high. The neck is longer. The legs are at the central fulcrum of the body for free walking. Has a flat beak with serrated edges to help filter food. It has the habit of migrating, and the migrating distance is also relatively long. It likes to live in groups, and forms an orderly queue when flying, with a glyph, herringbone, etc. It mainly inhabits freshwater waters in different habitats, often coming in and out of lakes, reservoirs, estuaries, flooded plains, wet grasslands, swamps and g...
