How to reduce the probability of duck's disease

It is believed that when using duck raising equipment to raise ducks, there will always be a problem of sick ducks. It can be said that this problem is inevitable, but we can reduce the probability of sick ducks to a large extent, so we need to carry out some operations to prevent it.
1. Reasonable selection of incubator
At the beginning of duck breeding, the selection of duck seedlings is very important. Only by improving the survival rate of ducklings can we lay a solid foundation for adult ducks. When selecting duck seedlings, the breeders should go to the hatchery with better epidemic prevention work to choose, and the hatchery should meet the national regulations and have complete certificates.
2. Selection of high quality duck seedlings
When selecting duck seedlings, the breeders should pay attention to that there are differences between good and bad ones. Generally, the breeders with good quality can feel the plump and powerful ducklings when holding them, and their feathers are also shiny, they look strong and lively, and their calls are loud. In addition, they should pay attention to the uniform size when selecting duck seedlings, so as to reduce the phenomenon of strong bullying and weak bullying.
3. Disinfection of duck house
In order to ensure that the ducklings can grow in a safe and healthy environment, the breeders should thoroughly disinfect the ducklings before transporting them to the ducklings house, including cages, tools and other items needed and all corners of the ducklings house, so as to ensure the health of the ducklings house and reduce the prevalence of ducklings.
4. Raise the temperature of duck house
Before transporting the ducklings to the duck house, the breeders should pay attention to the heat preservation of the duck house. Because the ducklings just out of the shell have poor temperature regulation ability, they must do a good job of heat preservation. It is suggested that the temperature of the house should be 30-32 ℃ for 1-3 days old ducklings, and then the temperature should be reduced by 1 ℃ every 2 days with the growth of ducklings. When the house temperature is close to the outside temperature, the heating should be stopped.
5. Regular disinfection
One time disinfection can not solve the problem of long-term health and safety. Ducks live in the duck house for a long time, so the germs propagate faster. The breeders must work out the procedures and time of disinfection, and do regular disinfection and frequent disinfection. Only in this way can the existence of germs in the duck house be reduced, the spread of germs to the ducks be reduced, and the health of the ducks be guaranteed.
6. Proportion of feed nutrients
Although the growth cycle of meat duck is short, the nutrition required for different growth cycle is different. In order to ensure the nutrition balance of meat duck in each stage, the breeder needs to make a reasonable feed according to the nutrition required for each growth stage of meat duck to ensure that the nutrition of meat duck in each stage reaches the standard, so as to increase the quality of meat duck.
7. Do a good job in immunization
Vaccination can effectively prevent the occurrence of infectious diseases of ducks, so the farmers should do a good job in the vaccination of ducks, and formulate a scientific and reasonable immune system, so as to reduce and avoid the occurrence of infectious diseases and ensure the health of chickens.
The above seven elements are the key points of using duck raising equipment to prevent duck from getting sick. I hope that they can be helpful to major farmers.
