1. Before entering the chicken house, all the places where the air enters and leaks in the chicken house must be dealt with, especially the fan, the cooling pad and the manure outlet at the back. Large, but these leaks will have an increasing effect on the temperature difference in the house as the ventilation rate increases.
2. The angle of the air outlet of the ventilation duct should be kept obliquely upward, and the angle of the deflector above the small window should be parallel to the roof of the chicken house, so that when the ventilation volume is increased, it can ensure that the cold air from the outside enters the chicken house and is fully pre-heated. After heating, it will fall down. In addition, for safety reasons, the upper cage must be covered with film.
3. All bulbs and light strips that are damaged or cannot reach the brightness must be replaced with new ones to ensure sufficient brightness when the chicks first come in. A large number of facts have proved that the dark lights seriously affect the chickens' eating, drinking and feed intake.
4. The chicken coop must be cleaned, especially the ground. Otherwise, the poor air quality in the chicken room will easily bring slow breathing and big rods to the chickens after entering the chicken room. Mycoplasma and large rods are not easy to occur in chickens in a good air environment. pole. In addition, the manure belt must be opened and empty several times to completely remove the manure water on it, and the feces discharged by the chicken after entering the chicken, because the water on the manure belt will aggravate its air pollution in the chicken house.
5. Before entering the chickens, the boiler must be ignited in advance to preheat the chicken house according to the season. It must be raised to about 35 degrees to ensure the temperature and humidity in the chicken house after entering the chickens, and then slowly drop to about 32 degrees. After the chicks are in, quickly raise the temperature in the chicken room until the chickens spread out evenly, because the positions of the probes in each chicken house are different, about 33 to 35 degrees.
6. In order to prevent the chickens from bathing, the water pressure of the water line must not be high. In addition, the water line should be raised to a relatively high level. After most of the chickens have adapted to drinking from the nipple, they will fall to a suitable position. In addition, the breeder must enter Drive the chicks frequently to ensure that the chicks start eating and drinking as soon as possible.
7. According to different seasons, the fan should be turned on for negative pressure ventilation in 2 to 4 days. If you use ventilation ducts, the negative pressure is not necessary to be so high. There will be no problem with 5 to 10, and a large number of smoke tests And the facts have proved this point, if you only have a small window, then the negative pressure must reach about 1.2 times the width of the chicken room. In addition, it is best to block half of the fan first, and use time control first. The cycle can be selected from 3 minutes to 5 minutes. The operating time can also be determined according to the situation. Start with a small ventilation and slowly increase it.
8. Open as many vents as possible, and try not to make the negative pressure too large, because chickens are very sensitive to wind speed. Chickens with a large negative pressure are easy to catch cold, so they need to walk around more frequently. The level of ventilation should be controlled by The state of the chicken flock is the standard. It is best to give the chickens the most comfortable body temperature. The chickens are evenly distributed, the feathers are neat, some are drinking water, some are eating, some are lying down, and a small part of the chickens are slightly open.
9. Strictly control the temperature difference in the chicken coop within half a degree. Where the temperature is high, the vents should be increased appropriately, and where the temperature is low, the vents should be relatively reduced. When you walk into the coop and close your eyes, you will not know where the vents are, and You will not feel the temperature change when you walk to any area.
10. There is almost no wind speed in the first week, and the cooling rate must be severe. It will drop to about 30 degrees on weekends. The ventilation volume in the 2nd and 3rd weeks is increasing rapidly, and the humidity is decreasing significantly, so the cooling rate must be slowed down. One time is the best. After 4 weeks, the chicken fluff has slowly replaced with old hair. At this time, the temperature can be appropriately increased, and the temperature can be reduced by 2 to 3 degrees per week. After 5 weeks, the temperature will continue to decrease, and the temperature can be reduced by 0.5 degrees per day After 33 days, if the flock is healthy, it will not be a problem to drop once a day.
11. The humidity in the chicken coop is also very important. However, due to the limitation of the natural environment in many cases, the humidity cannot meet the ideal requirements. At this time, the chickens must be observed frequently, and only the temperature can be used to compensate for the change in humidity.
12. On windy days, chickens are most likely to get sick. Humidify, heat up appropriately, do not turn off the lights, do not control the feed, and properly close the downwind vents or small windows.
13. When the outdoor temperature is close to the target temperature in the chicken room, the ventilation volume can be increased appropriately, because the temperature difference in the chicken room is the smallest at this time. On the contrary, the ventilation volume is appropriately reduced in windy weather. In the early stage, the temperature is the main factor, so don’t pay too much attention to the pursuit of large Ventilation, try to be conservative, and don’t pay too much attention to the temperature in the later stage, you should focus on ventilation, because the feathers of the big chicken are plump, and there is not much body temperature change. Basically, there is no need to consider the problem of catching cold. Letting go of your hands to ventilate is actually caused by poor management of the chicken flocks in the early stage, and the flocks themselves have diseases.
14. Another point that needs to be emphasized is that the furnace temperature of the boiler must be well controlled, especially the central heating. It can be said that the success or failure of brooding in winter depends on this boiler. I always have to keep an eye on the boiler room first after entering the chicken. , if necessary, add coal yourself, because if you are not careful enough, the furnace temperature in the boiler room will leave hidden dangers to your chickens in the whole field, and this kind of hard work is only temporary, which is far better than the chickens who have to use drugs, injections and Picking up dead chickens is much better.
15. I like to go to the chicken house with my shirt off to feel it, because this way I can feel whether there is a temperature difference between the chicken houses. As soon as I find that the chicken manure on the manure belt dries up or decreases, I will find out the reason immediately. Generally, it is not a lack. The water is to keep the net from falling and the chickens can’t eat the feed. I like to wait until the chickens have eaten up the feed before feeding. I think the feed troughs of good chicken farmers are often empty instead of full. The feed troughs are often Feed chicken farmers are actually not diligent, because they are unwilling to even the feed. As long as the chicken is well controlled, the chicken will bottom out soon after feeding.
16. There have been many debates about which is more suitable for the upper fan or the lower fan in the early stage. I think that as long as the angle of the vent and the falling point of the wind are well grasped, chickens can also be raised well. The difference between them is only the last ten meters There is a difference in the direction of the left and right wind, but the manure duct and the fan at the back have more or less ventilation, so the chicks will not have a dead angle for ventilation.
17. There are still many controversies about whether to close the ventilation ducts and use small windows alone or mix them when the ventilation ducts are not enough after more than ten days. I personally think that if the ventilation management technology is particularly good, the small windows can be used alone, and there is no mixing. The phenomenon of wind mutual interference is definitely the best strategy. However, in reality, who can control the angle of the small window and the negative pressure so well, so it is better to use the two together in terms of safety. Their air intake angles do not overlap, and there is no interference. If it is so serious, and the negative pressure does not need to be so high, the wind speed of the vents will not be so high, which will greatly reduce the chance of the chickens getting cold.
18. Many people may be unhappy about this point, that is, viral diseases. I only believe in the power and effect of vaccines and the immunity of the chicken body itself. I don’t believe in the magical effect of any antiviral drugs. Even if the disease is cured by treatment, then It is also the resistance of the flock itself that defeated the virus with the help of antiviral drugs. Both the rod and the respiratory tract are environmental diseases, and they can be completely avoided with good feeding and ventilation management, and it is even more impossible for the branch to be blocked.
19. I have never considered medicines for promoting the kidney and protecting the liver and kidneys. I only like medicines for big rods and slow exhalation. No matter how good the medicine is, it cannot make up for your ventilation management mistakes. It is impossible to prevent the occurrence of diseases, and no matter how good the feeding management is, scientific vaccine prevention is absolutely indispensable.
