Abstract

The invention discloses a method for hatching baby chick under variable temperature within 21 days. The method comprises the following specific steps of selecting eggs; from the first day to the seventh day, in a hatching machine, controlling the temperature to be 38.0 DEG C, and controlling the humidity to be 54 to 55 percent; from the eighth day to the fourteenth day, in the hatching machine, controlling the temperature to be 37.8 DEG C, and controlling the humidity to be 50 to 52 percent; from the fifteenth day to the eighteenth day, in the hatching machine, controlling the temperature to be 37.6 DEG C, and controlling the humidity to be 50 to 52 percent; from the ninth day to the twentieth day, moving all the hatching eggs in the hatching machine into a baby chick growing machine, in the baby chick growing machine, controlling the temperature to be 37.3 to 37.5 DEG C, and controlling the humidity to be 60 to 66 percent; at the twenty first day, in the baby chick growing machine, controlling the temperature to be 37.0 to 37.2 DEG C, and controlling the humidity to be 66 to 67 percent, so that the baby chick break shells and hatching for the baby chick is finished. The method has the advantages of high hatching rate, high survival rate and the like.

Description

The method of a kind of 21 days Hatchability baby chicks

Technical field

The present invention relates to a kind of method of hatching baby chick, specifically relate to the method for a kind of 21 days Hatchability baby chicks.

Background technology

Due to chicken and egg liking deeply by China people, therefore many in poultry enterprise of China.

In poultry industry, often need to hatch baby chick, at present, the method generally adopted directly is placed on inside incubation equipment by kind of egg to hatch, but control this block in temperature and humidity, what adopt is constant temperature and constant humidity scheme, but in the process of hatching, embryo self can produce metabolic heat, and the fluid loss in embryo's each stage self is also different, remain that constant temperature and constant humidity scheme carries out baby chick hatching, the defect that incubation rate and survival rate are all lower can be caused, therefore need correctly to adopt according to chick embryo development rule " to see that temperature executed by tire, execute wet " technology.

Summary of the invention

For solving the defect of prior art, the invention discloses the method for 21 days Hatchability baby chicks that a kind of incubation rate is high, survival rate is high.

The invention discloses the method for a kind of 21 days Hatchability baby chicks, concrete steps are as follows:

Step one: seed selection egg: will be placed in 150# incubator tray without deformity, fissureless kind of egg, and then the incubator tray piling kind of egg will be placed on egg car, egg car is moved integrally in hatch machine;

Step 2: 1-7 days: the temperature of hatch machine inside controls at 38.0 DEG C, and humid control is at 54%-55%;

Step 3: 8-14 days: the temperature of hatch machine inside controls at 37.8 DEG C, and humid control is at 50%-52%;

Step 4: 15-18 days: the temperature of hatch machine inside controls at 37.6 DEG C, and humid control is at 50%-52%;

Step 5: 19-20 days: transfer in young-generating machine by all kind eggs in hatch machine, the temperature of young-generating machine inside controls at 37.3 DEG C-37.5 DEG C, and humid control is at 60%-66%;

Step 6: 21 days: the temperature in young-generating machine controls at 37.0 DEG C-37.2 DEG C, humid control is at 66%-67%, and baby chick broken shell, chicken has hatched.

Because embryo self can produce metabolic heat, and along with embryo age increase and increase, therefore, the method of 21 days of the present invention Hatchability baby chicks is higher in hatching temperature in early stage. along with the carrying out of hatching, temperature reduces gradually, and in addition, the method for 21 days of the present invention Hatchability baby chicks can adjust humidity according to the difference of each stage fluid loss of embryo, therefore compare the hatching being beneficial to baby chick, incubation rate, the rate of being good for out and survival rate significantly improve.

Embodiment

The invention discloses the method for a kind of 21 days Hatchability baby chicks, concrete steps are as follows:

Step one: seed selection egg: will be placed in 150# incubator tray without deformity, fissureless kind of egg, and then the incubator tray piling kind of egg will be placed on egg car, egg car is moved integrally in hatch machine;

Step 2: 1-7 days: the temperature of hatch machine inside controls at 38.0 DEG C, and humid control is at 54%-55%;

Step 3: 8-14 days: the temperature of hatch machine inside controls at 37.8 DEG C, and humid control is at 50%-52%;

Step 4: 15-18 days: the temperature of hatch machine inside controls at 37.6 DEG C, and humid control is at 50%-52%;

Step 5: 19-20 days: transfer in young-generating machine by all kind eggs in hatch machine, the temperature of young-generating machine inside controls at 37.3 DEG C-37.5 DEG C, and humid control is at 60%-66%;

Step 6: 21 days: the temperature in young-generating machine controls at 37.0 DEG C-37.2 DEG C, humid control is at 66%-67%, and baby chick broken shell, chicken has hatched.

During 1-7 days, the temperature of embryo self is at 37 DEG C, and the fluid loss of embryo self is larger, therefore in step 2, the temperature of hatch machine inside controls at 38.0 DEG C, humid control is at 54%-55%, during 8-14 days, the own temperature of embryo is at 37.3 DEG C, the fluid loss of embryo self tails off, therefore in step 3, the temperature of hatch machine inside controls at 37.8 DEG C, humid control is at 50%-52%, and 37.8 DEG C are beneficial to the growth of chicken feather and closing up of embryo, the own temperature of 15-18 days embryos is at 38.2 DEG C, the fluid loss of embryo self becomes again large gradually, therefore in step 4, the temperature of hatch machine inside controls at 37.6 DEG C, humid control is at 50%-52%, and during 19-20 days, embryo breathes and transfers pulmonary respiration to, the temperature of embryo is at 38.5 DEG C, and the fluid loss of embryo and lung increases further, therefore in step 5, the temperature of young-generating machine inside controls at 37.3 DEG C-37.5 DEG C, humid control is at 60%-66%, now temperature controls to be beneficial to kind of an eggshell at 37.3 DEG C-37.5 DEG C and becomes fragile, be beneficial to broken shell, the condition that shell provides more favourable is gone out for step 6 chicken.
