First, the plateau should not raise broilers. At a plateau above 3,500 meters above sea level, the air is thin and oxygen is too low to meet the oxygen and caloric needs of broilers. This increases the burden on the heart and lungs, increases vascular permeability, and extravasation of body fluids, resulting in accumulation of water in the abdomen. Therefore, blind chickens at the plateau cannot be raised. So as to avoid unnecessary losses.
Second, the chicken immunization period should not use disinfectants. Chickens are banned from using disinfectants within 7-10 days of immunization, especially drinking water immunity. If disinfectant is used, it will kill the disease (bacteria) seedlings, leading to immune failure.
Third, distillers should not feed chickens. Chickens are toothless, have short bowels, lack 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.
Fourth, layers of chicken should not be fed bone meal. The bone meal is not treated with high pressure and the bone powder is combined with the bone glue. If the chicken is fed for a long time, the ratio of calcium and phosphorus will be imbalanced, resulting in a decrease in productivity.
Fifth, chicken pests should not use trichlorfon. Chickens have an alkaline environment within the crop, and trichlorfon can produce powerful DDVP, 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. Chickens should not be immunized during egg production. 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.
Seven, eggs should not be washed with water. There is a layer of glial protective film on the surface of the eggs, and the penetration of water and bacteria invasion. If the egg shell protective film is washed out with water, the quality of the egg will be reduced, and the hatching rate and the survival rate of the chicks will be affected. Therefore, eggs should not be washed with water and should be disinfected with benzalkonium before disinfection.
VIII, Furin is not suitable for drinking water. Furazolid is almost insoluble in water, and it easily precipitates in water. If a chicken drinks it, it can easily cause poisoning. Should be fed with spices, and to stir evenly.
Nine, we should not directly feed chickens. 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. Sorghum should be processed and processed into loquat powder.
Ten, egg sheds should not be disinfected with lime. 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. Therefore, it should not be disinfected with quicklime and can be formulated as a 10%-20% lime emulsion sprayed chicken house.
