Check harmful gases
The most harmful gas to chickens is ammonia and hydrogen sulfide, which can stimulate the sense organs of chickens, induce respiratory diseases and reduce feed efficiency. When smelling ammonia when entering a chicken house, ammonia gas in the house has been exceeded. The proportion of hydrogen sulphide is so great that the higher the concentration is, the closer to the ground.
When the following conditions occur in the house, it can be determined that there is an excess of hydrogen sulfide in the air: 1. The surface of the copper fixture becomes black. 2, galvanized iron surface has a white precipitate. 3, black art pigments fade. In addition, broilers insulated with coal stoves should beware of carbon monoxide poisoning by personnel and chickens. When the above three kinds of harmful gases are in excess, appropriate measures should be taken immediately, such as increasing the ventilation volume and changing the litter, etc., so as to reduce and eliminate the harm to chickens.
Check temperature
Check whether the temperature on the thermometer matches the actual required temperature. If the temperature difference is too large, immediate measures must be taken to control the temperature within the required range and keep it as relatively stable as possible.
Check ventilation
Especially in the low winter temperatures, people tend to notice only warmth and neglect ventilation. When it is well ventilated, the chicken is lively and there is no odor in the house, especially if the temperature and ventilation are appropriate, there will be a pleasant feeling. If the chicken is found to be snoring and breathing slightly, the house is full of dust and smells, indicating that the air in the house is extremely dirty and ventilation should be strengthened immediately.
Check the stool
Check the fecal color for bloody stools. In general, the feces of laying hens are soft and the feces of broilers are strips. Some diseases can cause diarrhoea in chickens. For example, chickens are yellowish-white when they suffer from Ganpo disease (infectious bursal disease) and infectious bronchitis; chickens have green, yellow-white watery stools when they get Newcastle disease. Blood in the house indicated that the chickens were mostly infected with coccidia. When abnormal feces are found, chickens that excrete should be found for diagnosis and treatment, and necropsy should be given if necessary.
Check the humidity
Higher humidity is conducive to the survival and reproduction of microorganisms. If the temperature is low, it will increase the harm of low temperature. When the humidity is low, the chicken house is dry and it is easy to induce respiratory diseases in chickens. Especially when the chicks are in a dry environment for a long time, they can cause dehydration and dehydration. Therefore, we must pay attention to the adjustment of the humidity of the shed.
Check light
In winter, the natural illumination time is short, which cannot meet the physiological needs of chicken egg production and requires artificial light to supplement it.
Check chicken drinking and eating
The consumption of laying hens is relatively stable. If there is a significant drop in chicken consumption or if only drinking water is not eaten, it indicates that the chicken has been infected with certain diseases. It is necessary to identify the causes as soon as possible and promptly treat them.
With the development of large-scale and intensive aquaculture, the scale of aquaculture is amazing, and the economic benefits in the absence of infectious diseases have indeed brought considerable economic benefits to the aquaculture industry. At the same time, it has made a significant contribution to promoting economic construction and improving human living standards. However, with the development of aquaculture today, there are many problems that have plagued the aquaculture industry, That is, livestock and livestock have been the timing of the outbreak of infectious diseases, which has brought huge economic losses to the entire breeding industry, so we have to rely on a large number of animal drugs, a large number of antibiotic drugs to fight against the outbreak, resulting in serious food pollution, such as: the residues of drugs and antibiotics in meat and eggs seriously exceed the standard, Excessive residues of a large number of drugs after use will directly threaten human health. However, this will bring disastrous consequences to the entire breeding industry, that is, human beings are more and more afraid to eat meat and eggs. If we continue not to start from the source of breeding pollution, then the consequences will be unimaginable.
Because the breeding environment can not be fundamentally improved from the source, the use of a large number of drugs and antibiotics can not be avoided. In fact, it is completely possible to realize ecological breeding and green breeding from the perspective of environmental cleaning and daily disinfection, and farmers can also save a large amount of drug costs.
