(1)Symptoms of cold and flu in poultry farm ?

Both wind-cold cold and wind-heat cold are common exogenous diseases. They may occur in the same season. If you want to relieve a cold quickly, you have to know whether you are suffering from wind-cold cold or wind-heat cold. In the process of poultry farm, many breeding Households do not know how to distinguish between wind-cold and wind-heat colds, resulting in the wrong direction of medication, and the more serious the treatment, the more serious the disease, which brings a lot of unnecessary losses.

一.The difference between wind-cold and wind-heat flu

The so-called wind-cold cold and wind-heat cold, the indications are that the disease pathogens first entered the body surface, and they are the symptoms of the symptoms within the range of the symptoms. All symptoms cannot be separated from this range. .

Let’s talk about the difference between the common cold and the common cold in poultry farm:

1, the mental state: a cold with a cold is caused by bad wind and cold.

Causing body pain. In the early stage, there will be apathy, drowsiness, and the phenomenon of false mental recovery after the weather warms up at noon. Because of the aversion to cold, there is the performance of avoiding the cold from heat. This is an instinctive reaction of the body, not a false performance. And the common cold won’t.

2, the amount of water you drink:.

Wind cold and cold belong to Yang, so in the early stage, you will not be thirsty, and you will not be greedy for drinking. However, wind-heat cold is a kind of yin injury, and the water intake will increase in the early stage. Although this heat can injure the yin, the evil is not on the outside, and the yin on the inside is abundant, so even if there is thirst, it is very slight in poultry farm.

3, body temperature.

Cold and flu will not cause systemic fever, and the fever parts are mainly the head and under the wings, while the legs are cold. A common cold will cause a generalized fever.

4, changes in the respiratory tract

In the anatomy of the casualty poultry farm due to wind-cold cold, the organs can be seen to be translucent. Only a small amount of bleeding occurs at the bifurcation of the trachea and bronchi, which is bright and bright, and there is a small amount of transparent secretions in the trachea. The wind-heat cold is different, the dissection of the tracheal ring is relatively dry but there is a lot of bleeding, and the secretions in the trachea are relatively thick and serious, and yellow viscous secretions appear. Therefore, wind-cold colds and runny nose are mostly wet rales, while wind-heat colds are mostly dry rales.

Respiratory symptoms in the early stage of a cold and flu may sound mild, but in practice (broiler chickens) in the early stages of the disease, many chickens with runny noses appear, even to the point of being obvious.

Wind heat and cold are obvious respiratory symptoms, but chickens with runny nose are rare or almost non-existent in the early stage.

5, the incidence trend

Wind-cold colds are mostly secondary to viral diseases, such as influenza, bronchitis, and throat transmission, which generally cause kidney-shaped bronchitis, but wind-heat colds often cause Escherichia coli and mycoplasma diseases.

6, death and egg production rate

Wind-heat cold can cause systemic fever and secondary infection of Escherichia coli, resulting in follicular necrosis, peritonitis, and serious decline in egg production rate. Dead chickens increased. However, poultry farms before the severe virus is not secondary to the cold, the chickens will basically not die, nor will it cause a sharp drop in egg production, and the egg production rate will be easy to recover.
