Keep chickens mastered to avoid temperature differences, and chickens stay away from respiratory diseases
Chickens get the respiratory tract, which will affect the feed intake in light, and cause the egg production rate to decrease and the mortality rate to increase in severe cases. Our farmers and friends are also very troubled by this disease, and some respiratory tracts can even last for one or two months.
So for the incurable respiratory problems, I wonder if everyone has considered the cause of the disease? It boils down to: temperature difference. Temperature difference is the root cause of respiratory diseases. Today we will learn together, what is temperature difference? What does the temperature difference include?
1 Seasonal temperature difference
mainly refers to the four seasons of the year, the impact of seasons on feeding and management, and the inconvenience caused by the change of climate when the seasons change.
2 Weather temperature difference
mainly refers to the changes and responses to feeding management when the weather is sunny, overcast, foggy, rainy, frosty, snowy, and windy.
In the breeding process, only by constantly changing with the changes of the environment can the chickens minimize the incidence of disease. Therefore, chickens like to be diligent and not lazy.
When it is sunny, pay attention to the temperature that changes with time, adjust the ventilation volume at any time, and it is cold and hot in winter, try to prolong the heating time of the boiler, and provide a guarantee for good ventilation. It is necessary to ensure effective ventilation in foggy days. Some farmers often close windows or ventilation pipes in foggy days, fearing that the fog will enter the chicken house. In fact, this approach is wrong, because the pressure in foggy weather is low, which is not conducive to the spread of pollutants. Closing the air inlet will only make the chicken house stuffy, resulting in a reduction in the ventilation volume in the house, and the air quality cannot be guaranteed.
When it is frost, it is often hot during the day and cold at night, especially from 1-5 in the morning. It is necessary to pay attention to less air inlets, reasonable negative pressure, and normal operation of the furnace.
When the snow is not cold and the snow is cold, the snow on the roof should be removed in time, and the temperature of the house should be appropriately increased, and ventilation should be careful, especially when the snow is melting.
The main consideration for the impact of sudden changes in weather and large temperature differences on breeding is to be quick and timely. Don’t think that it doesn’t matter if it’s cold for a while, and it doesn’t matter if it’s hot for a while. You must know the details to determine success or failure, understand the weather changes in advance, and take appropriate measures.
3 Temperature difference outside the house
The temperature difference formed by the temperature inside the house and the temperature outside the house is a very important reference index to understand the temperature difference between the inside and outside of the house, the opening and closing of the vent, and the size of the negative pressure.
4 For this problem, the temperature difference of the heat source
can appropriately increase the air intake in the high temperature area, so that the hot air flows to the low temperature area, and the air inlet in the low temperature area can be appropriately reduced or closed.
The heat sink or air supply bag used in the heater should be installed on both sides of the wall as far as possible, and the air should be blown toward the wall.
The main reason is that the chickens around the heat source of the house are different from the overall temperature of the house and the chickens slightly farther away from the heat source, especially for the chickens heated by the heater, and special attention should be paid to this.
5 The temperature difference at the entrance of the chicken
coop is generally cooler and the wind that comes in at the air inlet is the easiest to ignore. Therefore, the respiratory tract of more than 70% of the chickens is caused by the temperature difference at the entrance.
When there is a temperature difference of more than 10 degrees between the temperature outside the house and the temperature inside the house, the temperature in the house may not be low, but the temperature difference of its somatosensory temperature has changed greatly, so plastic paper should be used before entering the house. Prevent personnel from entering the chicken coop and take advantage of the cool wind to enter the chicken house. The wind blows directly to the chickens, and they catch cold and get sick.
6 The temperature difference of group
expansion refers to the temperature difference generated before and after group expansion. Fifteen percent of the respiratory tract has a certain relationship with the temperature difference before and after group expansion.
7 The temperature difference
between morning and evening refers to the temperature difference between morning and evening. If the temperature difference between morning and evening exceeds 10 degrees, the chickens will inevitably get sick.
Through the analysis of the temperature difference in the above 7 points, do you have a more detailed understanding of the temperature difference problem? The temperature difference covers a wide range. It is definitely not only the temperature difference between morning and evening and the external climate temperature difference. Only when we have a more detailed understanding of the temperature difference can we minimize the incidence of respiratory diseases in chickens.
