1. Temperature and ventilation problems

In winter, most farmers pay too much attention to heat preservation and ignore the important part of ventilation. At the scene of a household, the 37-day-old ducks had severe respiratory tract and severe ascites in the dead ducks. When entering the duck house, I found that the humidity was too high, there was running water on the wall of the duck house, and the ceiling was like rain. Some water droplets were dripping continuously, the ammonia smell was strong, the amount of air vents was too small, and the doors and windows were closed. Asked why not ventilation, the answer is afraid of the duck frozen.

In fact, the farmers have fallen into a misunderstanding on this aspect. After 28 days, the duck has plump feathers and has its own ability to resist cold. As long as the temperature is controlled at 20-24 degrees, do not appear high and low, the duck will be very comfortable. Often duck problems are caused by large temperature differences, hot and cold.

Although the duck epidemic is now more and more serious, and winter is a high incidence period. But the key is to do a good job of temperature and ventilation. Due to too much emphasis on heat preservation in winter, either the temperature is too low, the duck only catches a cold, or the ventilation is poor and the amount of oxygen is insufficient. Let the ducks be in a state of stress every day, and when the temperature in the house is too high and the humidity is too high, it is the environment where bacteria and viruses grow. When the ventilation is insufficient, these bacteria are brought out of the duck house through the air flow and settle in the house for a long time, becoming a big hidden danger. It is this environment that provides a "hotbed" for bacteria and viruses to reproduce and even mutate ".

2. The temperature control of brooding is not balanced

This problem is mainly in the standardization of the house, the duck before and after the temperature difference is too large. The temperature in the front column is better, but the temperature in the latter column cannot reach it. The problem is that when the temperature cannot reach it, the one-day-old duckling will have a serious phenomenon of pushing, which will affect boiling water and food, and form hidden dangers for the later growth.

The key to brooding is to watch the temperature of the ducks and adjust the temperature reasonably according to the distribution of the ducks. Don't put the temperature on a certain value. In one of the farms, when there was a problem at the age of one day, the breeding workers placed the temperature and humidity meter in the house under the hot air belt port. The hot air brought out from the hot air was just blown on the thermometer, which showed 39 degrees. When the workers recorded the temperature, they recorded the temperature, while the temperature controller outside showed 36 degrees in the house, and the temperature probe was in front of the second column. The ducks in the third column are pushing, obviously the temperature is not enough. If only temperature is taken as a data, it is meaningless. The appropriate temperature must be given according to the condition of the ducks.

3. The problem of duck incidence after 1 month of age

The main problems after 1 month of age are respiratory tract, air bag inflammation and pericardium liver. Most veterinarians diagnose influenza, or influenza-induced, as the virus disease is commonly known. But it may also be because of poor ventilation, poor management, stress and other factors caused by decreased resistance, and the excitation of mixed infection.

Therefore, winter ventilation and temperature must be coordinated, especially the management and health care of the early ducks is particularly important.
