Common diseases and solutions in spring chicken farming

Although spring has already begun, the climate is cold and variable, with a large temperature difference between day and night, and a significant difference in temperatures between the north and south. The immune and defense functions of chicken flocks are still at a low level. This period is also a period of frequent outbreaks of chicken diseases. Breeding farms should do a good job in epidemic prevention, enhance the resistance of chicken flocks, and prevent the occurrence and spread of diseases. So, what are the common diseases in spring chicken flocks? What are the issues to pay attention to when breeding?

1、 Common chicken diseases in spring
1. Respiratory diseases
The temperature changes greatly in spring, with a large temperature difference between day and night. After a winter, the chicken coop may be damaged, causing a decrease in the insulation effect inside the coop, which can easily cause stress reactions in the chicken flock and lead to the possibility of diseases in the chicken flock.
Some breeders seal their chicken coops too tightly to keep them warm, causing toxic gases such as ammonia and hydrogen sulfide to exceed the standard, which can also easily lead to respiratory diseases.
If the feces in the chicken coop are not cleaned up in a timely manner, the hygiene conditions are poor, and timely disinfection work is not done properly, it can also cause pollution to the chicken coop environment, leading to the growth of bacteria and causing respiratory diseases.
2. Chicken Newcastle Disease
Newcastle disease in chickens is a common disease in spring, which is a highly contagious disease caused by the paramyxovirus in chickens.
The main symptoms are mental lethargy, tightly closed eyes, dull eyes, dark red or purplish black cockscomb and droopy flesh, soft and swollen crop, filled with sour and foul smelling liquid and gas. Difficulty breathing, often stretching the head and neck, breathing with the mouth open, and frequent gurgling sounds in the throat; Feces that are yellow green or yellow white in color and have a long course of illness are often accompanied by neurological symptoms in sick chickens.
Clinically, respiratory symptoms are common, and the egg quality and production of laying hens decrease, with sporadic deaths.
3. Avian influenza disease
Avian influenza is an acute infectious disease of poultry caused by type A influenza virus. The most acute type is caused by a highly pathogenic virus strain, with no obvious symptoms and sudden death. Acute type is mainly characterized by respiratory symptoms, while chronic type is caused by medium to low virulence strains, with mild transient respiratory symptoms.
2、 How to prevent the occurrence of diseases?
Firstly, the enclosure should be kept warm and well ventilated
In early spring, doors and windows can be closed, grass curtains can be hung, or heating methods such as drinking warm water and a stove can be used to keep warm. If using a coal stove to increase temperature, close attention should be paid to gas poisoning.
Ventilation is the most important for chicken farming. While keeping warm, it is also important to ensure fresh air circulation in the chicken coop. In spring, the temperature is low and the breeding density is high. Often, attention is paid to the insulation of the chicken coop while neglecting ventilation and ventilation, which can easily lead to polluted air inside the coop and the proliferation of a large number of bacteria. Long term inhalation of harmful gases such as carbon dioxide by chickens can easily lead to a high incidence of diseases such as Escherichia coli and chronic respiratory diseases. So, ventilation cannot be ignored.
Secondly, do a good job of daily disinfection
Spring is the season for the revival of all things, and diseases are no exception, so disinfection is particularly important in spring. The early spring climate is still relatively cold, and the resistance of chickens is generally weakened, which can easily lead to disease outbreaks and heavy losses. Therefore, it is necessary to pay attention to disinfection work.
Again, ensuring sufficient nutrition and supplementing light in the feed
The weather in spring is unpredictable, and chickens have relatively weak resistance, so improving the nutritional level of feed is crucial. But different chickens also require different nutritional supplements. In addition, light can promote the metabolism of chickens and accelerate their growth, so it is necessary to meet the lighting time of chickens during the breeding process.
Finally, it is necessary to do a good job in disease prevention and control
Spring chicken flocks are prone to chronic respiratory diseases, avian influenza, etc. Therefore, it is necessary to do a good job in preventing chicken diseases. Once the disease is detected, early measures should be taken.
