Description

A kind of mechanical hatching method of breeding eggs

technical field

The invention relates to the field of breeding, in particular to a method for mechanical hatching of breeding eggs.

Background technique

The basic conditions for hatching are to have suitable temperature, humidity, and good ventilation conditions, and to turn eggs and cool eggs at the right time during the hatching process, and pay special attention to the hygienic conditions of the hatching room. Temperature is the primary condition for egg hatching. During the whole process of embryonic development, various material metabolisms are carried out under certain temperature conditions. Suitable temperature is the key to the success or failure of hatching. Too high or too low hatching temperature will affect the development of embryos. Humidity is closely related to the evaporation of water in the egg and the metabolism of the embryo, and has a greater impact on the development of the embryo. If the humidity is too high, the water in the egg will not easily evaporate, which will affect the embryonic development; if the humidity is too low, the water in the egg will evaporate quickly, which will easily cause the fluff and eggshell membrane to stick together. In the early stage of incubation, the embryo needs to form a large amount of amniotic fluid and allantoic fluid, and the temperature in the incubator is relatively high, so the humidity needs to be higher. During the development of chicken embryos, oxygen is continuously inhaled, carbon dioxide is emitted, and gas exchange is carried out.

In the early stage of hatching, the material metabolism capacity of the embryo is low and requires less oxygen. As the age of the embryo increases, the allantois develops, and the respiratory volume gradually increases. In the last 2 days of incubation, the embryo begins to breathe with the lungs, and the oxygen inhaled and the carbon dioxide exhaled It is more than 100 times higher than that in the initial stage of incubation. In order to protect the normal development of embryos, the incubator must have good ventilation conditions to ensure sufficient fresh air. Especially in the late hatching period, the ventilation rate gradually increases, especially during the hatching period. If the ventilation is insufficient, the number of dead embryos before hatching will increase. The incubator of present design all pays great attention to ventilator, has offered air intake hole and air outlet.

The function of egg turning is to make all parts of the embryo heated evenly, avoid adhesion with the eggshell, make different parts of the egg similarly heated, and promote gas metabolism, which is beneficial to nutrient absorption and increases the hatching rate. The machine hatch has an automatic or semi-automatic egg turning system, which can turn eggs regularly according to needs. Generally, eggs can be turned 4-12 times a day and night.

The purpose of cooling eggs is to help the embryos dissipate heat, promote gas metabolism, improve blood circulation, and enhance the ability of embryos to regulate body temperature, thereby improving hatchability and chick quality. Cooling eggs is to reduce the egg temperature in a short time. During natural hatching, the hen leaves the nest to drink water, feed, and defecate every day. This is egg cooling activity; during machine hatching, egg lighting and water spraying are also egg cooling tasks, but regular egg cooling must be done every day. In the early stage of incubation, the time for cooling eggs is shorter. After the 15th day of incubation, gradually increase the time for cooling eggs. Open the door of the incubator twice a day, turn off the heat source, only turn on the fan, and pull out the egg tray from the egg tray rack by 1/ 3. Then spray warm water on the eggs. As the age of the embryo increases, extend the cooling time. You can spray water on the eggs 2 to 3 times a day. The degree of cooling the eggs every day is as mild as the eyelids touching the eggshell. After cooling the eggs, push the egg tray back into the incubator, close the incubator door, and turn on the heat source. The time for cooling eggs varies with seasons, room temperature, and embryo age, usually 20 to 30 minutes. When incubating on a push bed, cool eggs are combined with turning eggs. Transfer the normally developed eggs to the hatching tray of the hatcher and continue to hatch until the shells are hatched. This process is called dropping.

The ideal conditions for the hatching room are: the room temperature is 21-24°C, the relative humidity is 50%-60%, the indoor air is fresh, avoid direct sunlight or cold wind directly blowing the incubator, the walls, ground and utensils should be clean and hygienic, and the utensils should be placed Neat and regularly disinfected.

Pay attention to the site selection and technological process of the hatchery; before entering the hatchery, the staff of the hatchery must go through showers and change clothes, and disinfect them regularly; after each batch of hatching, immediately wash and disinfect the equipment, utensils and rooms; pay attention to disinfection. Instead of rinsing, disinfection is only effective after rinsing thoroughly. Rinse the floor of the hatching room with high-pressure water, wipe the inner wall of the hatcher with a rag, and then sterilize it by fumigation; wastes such as fluff, eggshells, dead chicks, and chick feces from the hatchery are put into plastic bags and sealed, and sent to a place far away from the hatchery. treatment at the site; the sewage is discharged after being disinfected and meets the discharge requirements.

Factors affecting hatching include breeder chicken factors, egg breeder factors, hatching factors, etc. To improve hatching performance, firstly, the quality of breeder flocks should be improved to prevent inbreeding; To purify the breeder flocks, the fourth is to adjust the environmental conditions of the breeder houses to a suitable level, the fifth is to keep the breeder flocks healthy, and the sixth is to pay attention to the collection of breeding eggs, and carefully remove broken eggs, dirty eggs, deformed eggs and oversized or Eggs that are too small.

Contents of the invention

The invention discloses a method for machine hatching of breeding eggs. The adopted technical solution comprises the following steps:

Step 1. Before hatching, put the eggs on the hatching tray with the big end (blunt end) facing upwards, put the eggs on the shelf of the egg rack trolley, and push them into the fumigation room for disinfection or temporary storage;

Step 2, adjust the temperature to keep the temperature in the incubator at a constant temperature of 37.8°C, set the incubation humidity, and adjust the room temperature at 29-29.4°C. After the temperature and humidity are set, the knob cannot be twisted at will. It will cause heat loss, and at the same time, the eggs and the dancing tray will also absorb heat, which will cause the temperature of the incubator to drop temporarily, and it will return to normal after 3 to 6 hours;

Step 3, batch hatching or whole batch hatching is carried out, batch hatching generally hatches a batch of breeding eggs every 3 days, 5 days or 7 days, and hatches a batch of chicks. Entire batch hatching is to fill the incubator at one time. Large-scale hatcheries mostly adopt whole batch hatching, and machine hatching usually hatches a batch within 7 days. In winter or early spring, eggs should be parked in the incubator for several hours before hatching. Pre-warm the eggs so that the eggs gradually reach room temperature before incubating. Put the eggs into the incubator to prevent condensation from directly entering the incubator (about 37.8°C) from the egg storage room (about 15°C). Affect the hatching effect. When hatching in batches, the egg trays of each batch should be placed in a staggered manner, which is conducive to the uniform heating of each batch of eggs. The best time to hatch is after 16:00, so that the hatching time of a large number of chicks can be concentrated in the daytime, which is conducive to the work;

Step 4, observe and record the temperature and humidity of the machine display and the temperature and humidity of the door surface, and perform egg-turning operations at regular intervals;

Step 5: Open more than half of the air vents of the incubator, and then open all of them after placing them on the plate. When incubating at different temperatures, gradually open the air vents;

Step 6: Carry out 3 inspections on the hatched eggs, 5 days after the hatching, conduct the first inspection (head photo), pick out the sperm-free eggs and dead embryo eggs, if the fertilization rate of the eggs is found to be low, it should be adjusted in time To improve the feeding and management of roosters and breeder chickens, conduct the second inspection (second photo) on the 10th day after hatching. If the allantoic membrane has been "closed" at the small head of the egg at this time, it indicates that the embryonic development is normal. The control of the hatching conditions is also appropriate, and the dead embryonated eggs and the missed infertile eggs are removed, and the third inspection (three photos) can be combined with the transfer;

Step 7: Transfer to the tray, hatch until the 18th to 19th day, and transfer the eggs with normal development to the hatcher to continue hatching. When transferring the tray, if the embryo development is delayed, the transfer time should be postponed. Humidity in the device and increased ventilation;

Step 8, carry out chick picking and artificial midwifery, and start hatching on the 20.5th day after hatching. At this time, the temperature and humidity in the hatcher should be kept relatively stable, and chick picking should be carried out three times;

Step 9: For cleaning and disinfection, first soak the hatching utensils with water, remove the dirt with a brush, then disinfect with a disinfectant, and finally wash it with clean water, drain it for later use, spray it with 3% creol soap solution or use Fu The incubator was sterilized by formalin fumigation.

As a preferred technical solution of the present invention, in the step 4, turn the egg once every 2 to 4 hours, first press the button of the rotary switch, and then turn the rotary switch to one side after it stops automatically at 45° To the "automatic" position, the eggs will be turned automatically once an hour thereafter, and the above operations must be repeated when the power is cut off.

As a preferred technical solution of the present invention, in the step 4, observe once every half an hour, and record once every two hours.

As a preferred technical solution of the present invention, the egg shells need to be picked out each time the chicks are picked in the step 8.

As a preferred technical solution of the present invention, keep the hatching box dark during hatching in the step 8, and after picking the chicks for the second time, put the remaining embryonated eggs in a place with a slightly higher temperature, When picking chicks, pay attention to helping those embryonated eggs that are difficult to hatch by themselves. If the embryonated eggs have been pecked, perform manual cracking; if the membrane under the shell is still white, do not manually crack the shell. Peel off the egg shell about 1 cm, pull out the head and neck of the chick and put it back into the hatch box to continue hatching until hatching.

As a preferred technical solution of the present invention, the hatching chamber and hatching utensils should be overhauled, cleaned and disinfected before the incubator, and the hatching chamber and hatching utensils should be inspected and maintained before hatching to ensure normal operation. Thoroughly clean and disinfect the hatching room and hatching utensils. The steps are: cleaning→cleaning→spraying alcohol and disinfectant→seal fumigation. Second, make a hatching plan. According to the sales contract or the number of chicks, time and egg supply required by the farm Make hatching plans according to the situation, and arrange the hatching time and hatching quantity reasonably; the third is to prepare auxiliary supplies, such as egg lamps, thermometers, hygrometers, disinfection supplies, anti-epidemic syringes, motor belts, record forms and some low-value items. Consumables should be prepared one week before hatching.

As a preferred technical solution of the present invention, the fourth item to be prepared before hatching is to fully check whether the incubator's power supply temperature, instrument temperature measurement, automatic temperature control, egg turning and ventilation systems can be used normally before starting the hatch. Determine whether the temperature in the incubator is uniform, and be familiar with and master the performance and status of the incubator. After 1 to 2 days of trial operation, it is normal and then start to hatch eggs. In order to prevent the occurrence of temporary power outage accidents, there should be special power generation equipment or backup power supply, and voltage stabilizers should be installed in places where the voltage is unstable. The pre-hatch disinfection method is the formaldehyde fumigation method, that is, 30 ml of formalin and 15 grams of potassium permanganate are used for each cubic meter of space in the incubator, and the fumigation time is 20 minutes. Then turn on the exhaust fan to exhaust the formaldehyde gas.

Normal egg head photo shows obvious vascular network, air chamber boundary is obvious, embryo is moving, and the egg rotates and the embryo also rotates, and black eyespots can be seen, and the black eyes of the embryo can be seen during autopsy. There are vascular network distribution, live embryos are black and red, and thick blood vessels and embryo activities can be seen. The shadow of the yolk is seen, and the rest is transparent. When the egg is rotated, the flat yolk can be seen floating, and the fast rotation speed indicates that the egg is sterile; irregular blood rings or several blood vessels are attached to the eggshell, forming blood circles, blood arcs, and blood vessels. Spots or broken blood vessel remnants, and those without radioactive blood vessels are dead embryo eggs. When the eggs are illuminated on the 10th to 11th day after hatching, the boundary of the air cell is blurred, and the embryo is in the shape of a black mass. Sometimes the air cell and the lower part of the egg body can be seen. Bright, no blood vessels, or residual blood streaks or shadows of dead embryos are dead embryo eggs, and the small head of the three photos is bright, it is a dead embryo egg; the edges of the yellow air cells are neat, the blood vessels are red, and the air cells are much smaller It is an embryonic egg that develops slowly.

Emergency measures for power outages during incubation: cut off the power supply and increase the room temperature to 27-30°C; if there are eggs within 10 days, the air inlet and outlet holes should be closed to facilitate heat preservation; Turn the eggs once every 20 minutes, open the half door every hour and turn on the exhaust fan for 2-3 minutes to discharge the accumulated heat in the machine; if there are 17-day-old embryonic eggs, they should be placed on the plate in advance, and the temperature of the embryonic eggs should be closely observed Changes.

The hatchery is relatively independent, keeping a certain distance from other farms, maintaining correct airflow distribution in the hatchery at all times, and separating clean and dirty areas. Positive pressure should be maintained in the breeding egg storage room, hatching room, and chick storage room; negative pressure should be maintained in the hatching room, washing room, etc., especially the hair suction pipe in the hatching room must be sealed, all sucked into the fluff box, and flushed in time after hatching. Do a good job in the disinfection work of the hatchery, formulate disinfection procedures and disinfection systems, conduct regular microbial inspections, and understand and master the disinfection effect. In particular, it is necessary to strengthen the disinfection of incoming utensils, articles, personnel and breeding eggs, strengthen the cleaning and disinfection of all links in the incubation process, reduce the invasion of pathogenic microorganisms, and control the reproduction and spread of pathogenic microorganisms. The hatching room should be sprayed with disinfectant 2 to 3 times a week, cleaned up once a week, and thoroughly rinsed and disinfected with a high-pressure water gun after each hatching. Hatch trays, egg trolleys, and egg trays are all sterilized with disinfectant one by one before use. The ventilation equipment on the roof is cleaned once a week, and personnel entering the workshop must change their clothes.

Incubation conditions directly affect hatchability and chick quality. High temperature can easily cause abnormalities in the cardiovascular system, nervous system, kidney and embryonic membranes, as well as sticky shells, abnormal feathers, poor healing of the umbilicus, and frailty; low temperature can cause cardiovascular system disorders, slowed growth of fetal membranes, malabsorption of nutrients, Liver dysfunction, delayed hatching, dull fluff of chicks, etc. The level of hatching temperature is affected by factors such as hatching season, type of incubator, breed, age of the chicken, temperature of the hatching room, etc. It is necessary to master the technology of "watching the embryo and applying temperature", and adjust the hatching temperature appropriately according to the development of the embryo, so as to provide the best conditions for embryo development. moderate temperature. Ventilation can make the air in the incubation room and incubator fresh, reduce the carbon dioxide content, supplement oxygen, adjust the temperature and humidity, and is conducive to the normal development of the embryo. The method of ventilation is: close the damper on 1 to 2 days, open 1/3 of the damper on 3 to 12 days, open 2/3 of the damper on 13 to 17 days, and open it to the maximum after 18 days. important. Embryonic eggs are easily contaminated by pathogens, which seriously affect the quality of chicks hatching and chicks. Therefore, it is necessary to do a good job of disinfecting eggs before hatching, during hatching and during hatching to reduce the contamination of embryonated eggs.

Soak the hatching eggs on the sixth day of incubation with 3% complex vitamin B for 1 to 2 minutes to reduce the number of weak chicks and increase the rate of healthy chicks; when 1/3 of the embryonic eggs are pecked, the hatching performance can be improved; vertical laser irradiation Breed eggs for 20 minutes, the embryonic eggs develop well, and the hatching rate is high; for embryonated eggs that have been hatched for 18 to 24 hours, irradiate them with 30 watts of ultraviolet light for 10 to 20 minutes, which can increase the hatching rate by 6% to 10%, and the chicks are healthy; Do not fumigate with formalin after treatment, otherwise it will easily cause damage to the mucous membrane of the chicks and reduce the quality of the chicks.

Beneficial effects of the present invention: the present invention puts the eggs to be hatched on the shelf of the egg rack trolley and then pushes them into the fumigation room for disinfection, adjusts the temperature and humidity to set a suitable incubation temperature and humidity, and hatches the eggs in batches or as a whole , Observing and recording the temperature and humidity of the machine display, the temperature and humidity of the door surface, three inspections of the hatched eggs, moving the tray, picking up the chicks and artificial midwifery, cleaning and disinfecting the hatching utensils, can make the hatching performance better, The quality of the chicks is better and the work efficiency is improved.
