The most easily missed links in broiler breeding management

2020-12-11

Raising chickens is a delicate task, especially broiler chickens, which will be released for slaughter in just a few tens of days. Therefore, no errors are allowed during the entire breeding process. Even if there is a mistake in feeding management, it will have an impact on the final production performance, such as increased feed-to-meat ratio, substandard weight, increased rate of dead hunting, uncontrollable disease, and even forced to sell in advance, etc., which will eventually lead to direct breeding failure. Affect economic benefits.

Therefore, in the breeding process, we must continue to summarize experience and learn lessons. In actual operations, try to be as reasonable and accurate as possible to reduce the breeding risk to a low level.

1. Poor temperature control
 
There are two cases of poor temperature control, one is the temperature is too low, and the other is the temperature is too high.
 
Under normal circumstances, the temperature is relatively low, and the temperature is relatively high in most cases. Many people think that higher temperature chickens are easier to raise, so each time the brooding room temperature is raised to 35°C~36°C, or even higher. In fact, such a high temperature is not needed. After long-distance transportation, the chicks have shown slight dehydration symptoms. After entering the brooding room, they need to have a certain adaptation time. If they encounter high temperature as soon as they enter the brooding room, this is for the chickens. The group is a kind of intense stress, which can easily cause some chicks to become more dehydrated. Therefore, it is recommended that the temperature of the brooding room be controlled at about 30°C before the chicks enter the brooding room. After all the chickens enter the brooding room, the temperature should be gradually increased until the chickens are completely dispersed and adapted to the temperature of the brooding room. Then keep the temperature constant at this level.
 
Of course, low temperature in the brooding room is also not acceptable, it will cause severe chick umbilical inflammation, pullorum, malabsorption or non-absorption of yolk. In short, the brooding stage is very important, and poor management will affect the life-long growth of the chicken.
 
2. Unreasonable ventilation
 
Common manifestations of unreasonable ventilation include fear of ventilation and random ventilation. **It is more common that farms do not dare to ventilate, especially in the early stages of the feeding cycle. Many people think that chickens are young and afraid of cold. Or think that the environment in the chicken house is acceptable and no ventilation is needed. But this will lay hidden dangers for the later ventilation work. Don’t dare to ventilate in the early stage. If the chickens are more than 20 days old and feel that the air quality in the house is poor or the indoor temperature needs to be lowered for ventilation, if the ventilation is too large, the chickens will show discomfort and, in severe cases, will catch a cold. The phenomenon. If the ventilation is too small and the effect of improving air quality is not achieved, the chickens will still have respiratory problems.
 
The author here suggests that (especially in a closed chicken house) the chicks should be ventilated slowly when they enter the brooding room on the first day (not more than 4 days). The purpose of ventilation is to keep the air in the house fresh and sufficient oxygen. It is necessary to allow the chickens to adapt to ventilation as early as possible while maintaining the proper temperature of the chickens, so that when they are more than 20 days old and need to increase the amount of ventilation, the chickens can adapt and rarely catch colds. .
 
There is also chaotic ventilation, regardless of the state of the chickens, just open windows and fans at will based on your own imagination and feelings. This management method is not advisable.
 
3. Poor humidity control
 
Humidity is more difficult to grasp than ventilation. Because of the advanced breeding equipment, most of them are supplied by hot air stoves. The temperature required during the brooding period is high, so the hot air stoves work continuously, resulting in dryness and insufficient humidity in the house. This will have an impact on the respiratory system of the chickens, especially the lungs, which are afraid of heat and dryness. Therefore, high temperature and dryness can damage the lungs and cause later pneumonia and air sacculitis. There are also high humidity, especially in winter when the chicken house is closed and the moisture cannot be discharged. The walls and roof are all fine water droplets, which will cause enteritis, colibacillosis, arthritis, and staphylococcal disease in chickens. And other diseases.
 
4. Excessive reliance on equipment
 
Some farms have a lot of investment and advanced equipment, but the chickens are still poorly raised. The main reason is that it relies too much on equipment and ignores human factors. For example, ventilation. After adjusting the fan and vents and setting the time control, it is assumed to be in place, instead of observing the status of the flock frequently. If the weather changes or the fan stops, the chicken house will become stuffy (especially It’s the second half of the night) The air is not circulating. For another example, when you press the button, the automatic feeder will start slowly, so you can rest assured. If you can't finish eating in some places, or don't eat enough in some places, you need to artificially mix them, otherwise the chickens will have different sizes of individuals, which will lead to gastroenteritis.
 
In addition to these two situations, there are actually many situations, such as relying on a temperature meter, relying on a negative pressure meter, etc., which will not be repeated here. In short, while the farm uses advanced equipment, it cannot rely solely on the equipment to be lazy. On the contrary, it must be more diligent to achieve foolproof feeding and management.
 
5. Unreasonable medication
 
When it comes to medications, some people are reluctant to use them and try to buy cheap drugs in order to reduce costs. Some people do not count the cost, as long as they hear that it is a good medicine, they use it regardless of the situation. Some people are fond of western antibacterial drugs, some are superstitious in Chinese medicine, and micro-ecological preparations.
 
Drugs can save lives when used well, but will be fatal when used badly. When we are breeding, we must use drugs rationally and not go to extremes. This requires reasonable arrangements based on the breeding environment, disease prevalence, the state of the flock, and the pharmacological effects of drugs.
