1. The plateau should not raise broilers. At a plateau above 3,500 meters above sea level, there is less oxygen, which can not meet the oxygen and calorie needs of broilers, aggravating cardiorespiratory burden, increased vascular permeability, extravasation of body fluids, and abdominal cavity accumulation. 2. Disinfectants should not be used during immunization of chickens. Chickens are banned from using sterilizing drugs for 7 days to 10 days, especially drinking water. If disinfectant is used, it will kill the disease (bacteria) seedlings, leading to immune failure. 3. Distillers should not feed chickens. Chickens have no teeth, short bowels, lack of enzymes that decompose cellulose, and distillers grains contain large amounts of crude fiber, so chickens cannot digest and use distillers grains and directly affect the absorption of other feeds, causing indigestion. 4. Eggs should not be fed with bone meal. The bone meal is not treated with high pressure. The bone powder and the bone glue are linked together. If the chicken is fed for a long time, the ratio of calcium and phosphorus will be imbalanced, resulting in a decrease in productivity. 5. Chicken pests should not use trichlorfon. Chickens are alkaline in their crops, and trichlorfon is capable of producing highly virulent dichlorvos, which can easily cause poisoning. Therefore, chickens should not be used to insecticide trichlorfon, can be used to drive carbuncle, levamisole and so on. 6. Egg production should not be immunized during the egg production period. Immune injection at the height of egg production often causes diarrhea in chickens, sagging wings, dullness, deprivation, production of soft shell eggs, or suspension of production, etc. Severe cases may occur with claudication or paralysis or even death. Therefore, chickens should not be immunized during the egg production period and should be carried out during the rest period. 7 days before and after immunization, vitamin B2, yeast, and cod liver oil should be added to the feed. 7. Furin should not drink water for chickens. Furazolid is almost insoluble in water and can easily accumulate in water. If chickens drink it, they can easily cause poisoning. Should be fed with spices, and to stir evenly. 8. Do not feed chickens directly. Scorpion is a high-protein feed for animals, but it is not appropriate to directly feed chickens. Because it contains intermediate hosts such as nematodes, it is easy to cause parasitic diseases. The wolfberry processing should be settled into wolfberry powder feeding. 9. Egg hens should not be disinfected with quicklime. Lime disinfection chicken sheds can easily cause chicken toe burns; eating lime into the gastrointestinal tract can cause gastroenteritis, edema, ulcers, and respiratory diseases in chickens.
