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...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the existing problems: sterilization treatment, adopting formaldehyde or formalin solution to sterilize fresh duck eggs, all of which have strong toxicity and teratogenicity, and will have a greater impact on the development of embryos; The selection of breeding eggs usually only recognizes the appearance, but does not identify the weight and storage period. The quality of the breeding eggs is poor, the hatching rate is low, the immunity of the ducklings is poor, and the survival rate is low; The meeting caused abnormal hatching, and the heat generated by fluorescent lamps and eggs during hatching, the higher the temperature in the later stage of hatching, without cooling and heat dissipation treatment, it will cause bad hatching embryos or even death
