Method for increasing duck egg hatching rate

Abstract

The invention discloses a method for increasing the duck egg hatching rate. The method is characterized by comprising the steps of 1, hatching egg selection, wherein the hatching egg weight, eggshell mass, vibrating sound and storage time are screened; 2, sterilization, wherein chinaberry leaves and azadirachta indica leaves are adopted as main extraction raw materials, pulverization, cooking and concentration are performed to obtain a plant sterilizing solution, and hatching eggs are soaked with the solution to be sterilized; 3, hatching bed laying, wherein matrix components are subjected to high-temperature sterilization, then, a hatching bed is laid, and upper and lower fluorescent lamps and a lower ventilation system are arranged; 4, hatching, wherein water is added into the plant sterilizing solution for dilution, the solution is sprayed one time every day, a folic acid solution is used for performing atomization on duck eggs, and the hatching temperature is adjusted. Compared with a control group, according to hatched ducks, the hatching rate is increased by 7.74%, the morbidity rate is lowered by 2.74%, the distortion rate is lowered by 0.50%, and the growth cycle is shortened by 15 d.

Description

technical field

[0001] The invention belongs to the technical field of poultry hatching, and in particular relates to a method for improving the hatching rate of duck eggs. Background technique

[0002] Hatching technology, an important way for poultry reproduction, is divided into female hatching and artificial hatching. At present, artificial hatching has occupied the main hatching market; female hatching is to heat fresh eggs through the body of the mother during the estrus period to promote the embryonic development in the egg body , the temperature during incubation is the temperature of the mother body, and the temperature is more natural, but the incubation time is long, the temperature remains unstable, and the hatching output rate is relatively low; while the artificial incubation technology provides suitable temperature, humidity and air circulation in the incubator, etc. Conditions, so that the embryos in the eggs develop and grow, the hatching rate is high, the s...

Embodiment 1

[0016] A method for improving hatchability of duck eggs, comprising the steps of:

[0017] (1) Breeding egg selection: choose duck eggs with a weight of 62-68g. The eggshell is not too thick, too thin, or rough. Pick it up and shake it gently without sound, and keep the duck eggs within 2-4 days. The longer the storage time, the more cells The lower the activity; by limiting the weight, eggshell quality, shaking sound and storage time, the overall quality of the eggs can be improved and the hatching rate can be improved;

[0018] (2) Sterilization: Mix neem leaves: neem leaves: neem fruits in a mass ratio of 4:2:1. After crushing, add water 5.5 times the total mass, ultrasonically oscillate for 23-28 minutes, and then cook in boiling water for 1.5 hours. After filtering and concentrating to 1 / 3 of the original volume, a plant sterilizing liquid was prepared; the duck eggs were soaked in the plant sterilizing liquid for 8.5 minutes to obtain a sterilized duck egg; the azadirach...
