Egg hatching sieve

Abstract

The invention relates to an egg hatching sieve, which belongs to the technical field of the livestock raising. The egg hatching sieve comprises a sieve bottom and a fence on the periphery of the sieve bottom. The other periphery of the sieve bottom is provided with a ventilation sieve fence. The ventilation sieve fence takes a shape of grid. The invention has the advantages that the ventilation fence is additionally arranged on the sieve bottom and the width between every two grids of the fence is enlarged, thus, the egg hatching sieve has good ventilation, the temperature and the humidity are uniform and the transmission of oxygen is guaranteed; for the chicks hatched by using the egg hatching sieve, the hatching rate is improved over 2 percent and the health chick rate is improved over 3 percent; no phenomenon of weak chicks caused by oxygen-poor occurs; the survival rate reaches over 98 percent; the weight increment is improved over 8 percent; and the economic benefit is increased.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, in particular to a brooding egg hatching screen used for hatching poultry. technical background [0002] At present, the hatching sieves used in hatching places are usually rectangular frames, and there are holes in the fence and the bottom of the hatching sieves, and the hatching sieves are arranged in layers. It has the following defects: there is no ventilation channel between two adjacent layers of sieves, and the sieve holes at the fence and the bottom are small. When eggs are hatched, especially when eggs are hatched with a high fertilization rate, the space inside the sieve is narrower due to the presence of eggshells, chicks and unhatched eggs in the chick sieve, and the chicks are crowded, resulting in poor ventilation, temperature, and humidity. Unevenness, lack of oxygen in the hatching sieve, poor breathing, weak constitution, increased number of weak chicks, severely reduce...

Problems solved by technology

It has the following defects: there is no ventilation channel between two adjacent layers of screens, and the screen holes at the fence and the bottom are small

When eggs hatch, especially when eggs are hatched with a high fertilization rate, because there are eggshells, chicks and unhatched eggs in the chick sieve, the space in the sieve will be narrower, and the chicks will be crowded, resulting in poor ventilation, temperature, and humidity. Unevenness, lack of oxygen in the hatching sieve, poor breathing, weak constitution, increased number of weak chicks, severely reduced survival rate, affecting hatching quality, and increasing economic losses
