Factors that affect chick quality and survival rate

In the chick management process, it should be clear that the factors affecting the quality and survival rate of chicks are: feeding and management of breeding chickens, hatching of hatching eggs, and feeding and management of chicks. Moreover, there is a complementary relationship between these three parties. In order to get the best production performance.

1, breeder respect

The health of breeders is important. Chickens should be protected against horizontally transmitted diseases; they should be fully vaccinated according to immunization procedures and ensure that high maternal antibody levels are passed on to offspring to prevent vertical transmission of the disease.

2, eggs

2.1 Collection of Eggs If artificial nests are used, litter should be protected from contamination by Aspergillus. Microbiology testing of litter and egg banks in the nests should be conducted periodically to determine the presence of Aspergillus and other pathogenic bacteria. . And do regular replacement. Eggs are regularly collected 3-4 times a day and collected in time to prevent contact with air, ash or other carriers.

2.2. Disinfect the eggs After the eggs are collected, they should be washed and disinfected as soon as possible to prevent the bacteria from penetrating into the eggshell. Sterilization of eggs should be done using an approved chlorine-containing or phenolic disinfectant and used according to the instructions on the label.

2.3. Storage and Transportation of Eggs Eggs are stored at 15.6-18.3°C and 60%-70% humidity, and are routinely inspected by microbiology and periodically replaced with litter in the nest box. In addition, the time for keeping the eggs should not exceed 3 days, and the eggs should be transported with a suitable temperature and humidity environment, which will help to obtain the best hatching rate.

2.4. Hatching of eggs

(1) Hatchery design: In the hatchery, the handling and workflow of hatching eggs and chicks should be divided into "clean area" and "non-clean area". However, this point is often overlooked when the hatchery is expanded and should be noticed.

(2) Ventilation of the hatchery: First, the ventilation equipment of the hatchery should have the function of effectively improving air in the house; Secondly, attention should be paid to the installation position of the ventilation equipment, especially the location of the air inlet should be able to avoid the waste gas discharged nearby. Direct access; In addition, should pay attention to the appropriate ventilation, to ensure that the set positive pressure zone and negative pressure zone.

(3) Cleaning and Disinfection of Hatchery: Cleaning of the site and disinfection of the equipment should be based on the approved approved cleaning agents and disinfectants, and be formulated and used according to the instructions. At the same time, pathogens should also be monitored regularly. The monitoring targets include aspergillus and other fungi in addition to pathogenic bacteria. If there is any pollution, etc., investigate the cause as soon as possible and take appropriate remedial measures.

(4) Embryo vaccination: The equipment used should be thoroughly disinfected. The embryo egg inoculator should be carefully maintained and used according to the instructions. Regardless of whether embryos are inoculated, inoculated subcutaneously or sprayed, the inoculum scale is calibrated and tested and Marek vaccines are carefully prepared and preserved. These measures are essential for producing a safe immune response because it is related to the health and quality of the flock.

3, chicks

3.1. Precautions for handling hatching In the mechanized hatchery, the number of hatches per batch is large. When performing chick processing, care should be taken when using a chick classifier, counter, etc., and brutal behavior must not be used to prevent harm to the chicks.

3.2. Precautions for chick transportation

(1) The chicks should be sent to the farms as soon as possible after hatching.

(2) The vehicle should be well ventilated and regularly disinfected.

(3) If the young animals are transported during the summer to avoid starting at 12 o'clock noon, and do a good job to prevent the heat to cool, winter will have to keep warm. Any neglect will affect the viability of the chicks at the beginning of the brood. Therefore, the hatchery and the farm should be linked and prepared in advance. In this way, when the chicks arrive at the farm, they can be placed directly in the fully prepared brooding room, and the chicks' survival rate and quality can be improved.
