How can chicken farmers prevent respiratory diseases in chickens?

Before how to prevent poultry respiratory diseases, list the main pathogens that cause poultry respiratory diseases, after all, pathogens are the main causes of diseases.

1. Viral pathogens that cause respiratory diseases.

Newcastle disease is a paramyxovirus that causes tracheal ring hemorrhage and can be prevented and controlled.

Avian influenza is an influenza virus that causes respiratory and other systemic diseases and is immune to prevention and control.

Infectious laryngotracheitis is a herpes virus that causes laryngotracheitis and can be prevented and controlled immune.

Infectious bronchitis Coronavirus sinusitis, bronchitis and tracheitis, and in severe cases, salpingitis and nephritis can be prevented and controlled.

Avian pox is an avian pox virus that causes laryngitis, tracheitis, and/or pox and can be prevented and controlled by immunization if necessary.

Marek's disease is a herpes virus that causes tumors such as the lungs and can be immunized.

2. Bacteria, fungi, mycoplasma pathogens that cause respiratory diseases.

Mycoplasmosis is a mycoplasma that causes chronic bronchitis and chronic balloonitis.

Mycoplasma synovial fluid in chickens belongs to the family of mycoplasma and causes mild tracheitis and balloonitis, arthritis Establish mycoplasma-free offspring.

Infectious rhinitis belongs to Haemophilus parachiosis and causes conjunctivitis, sinusitis, and balloonitis, which can be prevented and controlled immunmatically.

Balloon inflammation belongs to Escherichia coli and is usually associated with other respiratory pathogens and is partially immune effective.

Pasteurellosis is a bacterium multocida that causes conjunctivitis, tracheitis, and the acute form is sepsis, and immunization may be effective.

Aspergillosis belongs to the subspecies of Aspergillus that causes respiratory distress and is ineffective in immunization and requires hygiene management.

3. Parasitic pathogens that cause respiratory diseases.

Balloon mites belong to the oligohaired chicken mite, which causes shortness of breath and airsac inflammation and isolates wild birds.

Cryptosporidiosis is a subspecies of Cryptosporidium that causes respiratory distress and cough and requires hygienic management.

A lot of space has been devoted to the common pathogens that cause respiratory diseases, and the following are the prevention and control measures:

1. Strengthen feeding management: do a good job of sanitation and disinfection; Strengthen the ventilation of the chicken house; Strictly control the ambient temperature and humidity; ventilation and warmth in winter and spring; all-in, all-out feeding method; Prevent moldy and spoiled feed.

2. Standardize the combination of introduction and monitoring.

Strengthen disease surveillance in breeding flocks, use serological methods to detect antigens or infection antibodies, eliminate positive chickens, and leave negative chickens as breeders, whose offspring can ensure the health of the flock. Immunization can control the occurrence of these diseases if vaccines are available; If there is no vaccine yet, positive chickens can only be eliminated through infection antibody monitoring. While doing a good job in Newcastle disease and branch immunization, it is also necessary to strengthen the immunization of avian influenza inactivated vaccines, so as to avoid greater losses caused by the disease and other respiratory pathogens.

Buy some medicines, you can buy drugs to prevent this disease, so that you can prevent this disease very well.

First of all, we should pay attention to ventilation, and then pay attention to the surrounding environmental hygiene, so that we can effectively prevent it.

The prevention and prevention of chicken respiratory diseases should abide by the following principles: the principle of prevention first, focusing on the prevention and vaccination of various viral diseases; Secondly, do a good job in breeding health management, prevent heatstroke and cool down in summer, keep warm in winter, control the density in the chicken coop, and ensure the ventilation of the chicken coop. Macrolides:

Tylosin, lincomycin, this class of drugs mainly has a specific effect on mycoplasma, among which tylosin can prevent the adhesion of Escherichia coli to the respiratory tract. Sick chickens have mild respiratory symptoms, sick chickens snort, sneezing, snoring and coughing after 3 days, panting (abdominal breathing), mouth opening, neck stretching, and strange screaming 5-7 days after the onset of the disease.

This disease is generally more than 25 days after the birth of carnivorous chickens, the feed intake of the sick flock decreases, individual chickens pull yellow-green thin feces, chickens show serious respiratory tract, snoring, coughing, individual chickens stretch their necks and wheezing. Anatomical tracheal congestion is severe, pulmonary congestion, intestinal bleeding, and edema. There are many causes of respiratory diseases, poor management, poor ventilation, temperature, humidity and stress caused by respiratory tract, ** scheme is definitely different, such as respiratory disease caused by cold into the body, first of all, the cold in the lungs must be discharged, in order to ** respiratory tract, otherwise even if the respiratory tract is suppressed, the drug will stop and viral respiratory diseases will recur, including mild avian influenza (H9), Newcastle disease, infectious bronchitis, infectious laryngotracheitis, etc.

After the occurrence of respiratory diseases in <> chickens, in order to quickly control the disease and prevent the spread of the epidemic, prevention and control measures must be taken, and timely application of drugs**, antiviral drug Hu Dukang, respiratory medicine Wan Hu Ning, with Escherichia coli medicine rod rick water to drink for 4 days, severe patients need to take another course of medication. The onset of the disease lasts until slaughter at the age of 15-20 days. Onset usually occurs 3 to 5 days after vaccination.

Chicken farms with poor hygiene, poor ventilation, polluted air, and high ammonia concentrations are more serious. The disease can occur all year round, and it occurs frequently in spring, autumn and winter.

I think that if the broiler chickens we raise in winter have respiratory diseases, we should ask the veterinarian in time and ask them to prescribe some drugs to ** the disease.

Drugs that specialize in respiratory diseases can be used, and it is best to ask a professional veterinarian to come and diagnose it.

If you want to prevent and control the occurrence of chicken respiratory diseases, you should first do a good job in the environmental sanitation and disinfection of the chicken coop, clean up the feces in time, replace the bedding in time, and thoroughly disinfect the chicken coop, waterline, trough, utensils, etc.

Secondly, do a good job in the ventilation of the chicken coop, discharge the harmful gases, dust and moisture in the chicken coop, so that the air in the chicken coop is kept fresh;

1**The respiratory tract does not rely only on drugs, the most important factor is ventilation, especially in the middle and late stages of raising chickens, the biggest reason for the respiratory tract to be cured is the harsh environment, without a good living environment and fresh air, it will be difficult to see the effect.

2. New chicks, respiratory conditions within 7 days, if not cold, the only reason after ruling out mold poisoning and gas poisoning is the problem of chicks: mycoplasma and salmonella.

After immunizing with Chinese medicine to improve immunity for three days before and after Tianshou immunization, immediately use mycoplasma drugs to prevent: tylosin, Archie, tilmicosin, etc. for 5 days. Practice has proved that it takes about 17 days for a full recovery of reactions such as nasal shakes after immunization.

For immunization between the ages of 25 days, it is best to use Chinese medicine to improve immunity for three days before immunization, and if there is a respiratory disease after immunization, antiviral drugs + respiratory drugs are preferred.

5. After the chicken is raised to 2 exemptions, it is necessary to pay attention to the renal branches, if the respiratory tract is not loud, directly use respiratory medicine ** 2 days after the sound is small, but immediately there is death, feed intake is sharply reduced; If the dead chicken is dehydrated and the kidneys are swollen, then the presence of the renal branch should be suspected. To add corn, reduce protein, and add baking soda in time.

If there is respiratory chicken disease in the future, it will be treated as Newcastle disease, influenza and E. coli**.

With the continuous development of social economy, in real life, we will encounter a variety of situations, especially for chickens, which poultry diseases to pay attention to, but also let many friends express great concern about this, in fact, I did not know, for chickens, we must pay attention to hypochondria and low temperature disease, because once these two diseases occur, our poultry are likely to die directly.

First of all, we must understand such a problem, that is, we must pay attention to osteomalacia in the process of oxygen, especially in winter, osteomalacia is more prone to occur, the occurrence of osteomalacia is often caused by the destruction of the metabolism of calcium and phosphorus, and the specific symptoms of the disease are that the pathogenesis is manifested as dysplasia, malnutrition, feathers are very unkempt, bones will become very soft, there will be cylindrical hard nodules at the joints of the joints, and the chest will be very flat. Protruding to the sides, but when this disease occurs, we must give the chickens enough vitamin D and calcium.

In addition to this disease, we should also pay attention to hypothermia, because hypothermia is also the cause of poultry death, the occurrence of hypothermia is also related to the season, especially in the northeast and other areas where the season changes greatly, when the concept demand in poultry is relatively large, if the feed intake can not keep up, then it will cause abnormal growth of bone tissue, thus forming a nutritional disease that contrasts with each other, that is, we are familiar with hypothermia, when hypothermia occurs, It is clear that the eggs laid by poultry are very small, and the quality of the eggshells is very poor, which seriously affects the profitability of chicken farming.

To sum up, we can obviously know that when we are raising poultry, we must pay attention to these contrasting diseases, because only by preventing these corresponding diseases can we ensure our profits and bring us better results.

First of all, we must pay attention to avian influenza, including hypochondriasis, and hypothermia, and then according to different situations, we must find a reasonable way to solve it, and we should also ensure the cleanliness and hygiene of the environment.

These diseases that should be paid attention to are, osteomalacia, chicken colibacillosis, hypothermia, bronchitis, chicken plague, avian influenza, and avian cholera, which should be paid attention to prevention and control.

Diseases to watch out for are chicken plague, avian influenza, avian cholera, infectious bronchitis, infectious bursitis and so on.

For example, there is osteomalacia, which is a disease that occurs easily in winter and is often caused by a lack of calcium. And be sure to pay attention to hypothermia, which is also related to the season, so be sure to pay attention to the fact that it can also cause abnormal growth of bone tissue.

1.Strengthen the management of feeding.

In summer, be sure to ensure the ventilation of the chicken coop, change the water and bedding in time. Chickens in each growth period should be raised in separate circles, not mixed, and the breeding density should be reasonable. Feed should be fresh, free of spoilage and musty smell.

2.Pay attention to vaccination.

For chicks, we must pay attention to the vaccination of vaccines, and the vaccination must be based on the immunization program to prevent the epidemic, so as to achieve the institutionalization of immunization procedures and epidemic detection, so as to avoid the occurrence of diseases to the greatest extent. If you don't know how to deal with problems with chickens, you can go to the cloud to consult experts, which is the world's largest agricultural technology Q&A platform. It brings together tens of thousands of experts in planting and breeding, and every question asked will be answered within 2 minutes.

3.Pay attention to hygienic cleaning.

Sanitation is very important for any breeding project. The inside and outside of the chicken coop must be cleaned frequently, the drinking trough and drinking fountain should be washed frequently, and the disinfection should be carried out regularly, and the prevention and control of mosquitoes, flies and rodents should be paid attention to. Chicken manure must be cleaned up in time, and the removed chicken manure must be fermented, otherwise the smell will be very big.

To prevent the occurrence of diseases, the disinfection of the breeding place, the temperature should be controlled, and the following points should be paid attention to when raising chickens in summer:

One is to reduce the feeding density. The flock is particularly sensitive to heat, and the feeding density of the flock should be reduced in time according to the rise in temperature.

The second is to change drinking water frequently. In summer, the water in the chicken food bowl is easy to be heated by the sun, so the drinker should be placed in a cool place, and the water should be changed frequently, preferably with pure cool water underground.

The third is to put it in the morning and circle in the evening. In summer, as soon as the day dawns, the chickens should be put on the activity ground, fed, and then circled after dark to minimize the time the chickens stay in the chicken coop. After the ambush, you can also build some wooden racks in the orchard for the chickens to perch on, so that the chickens can spend the night under the pergola.

Fourth, scientific feeding. In summer, there are long hours of sunshine, so the frequency of feeding should be increased. Feed more in the morning and evening, feed less at noon, and feed each meal twice, with an interval of half an hour, in order to induce chickens to enhance their appetite.

Fifth, do a good job in epidemic prevention. In summer, there are many mosquitoes and flies, which can easily spread diseases. Therefore, it is necessary to conscientiously do a good job in the disinfection and epidemic prevention work of the chicken coop to prevent the occurrence of diseases. The coop should be cleaned once a day, and the sand should be padded frequently.

Reduce stress. Chickens are timid, easily frightened, and sensitive to changes in the external environment. Therefore, there must be a certain time and sequence for the work of feeding the chickens, adding water, picking up eggs, disinfection, cleaning, and cleaning up manure.

Work slowly, and strangers and other animals are strictly forbidden to enter the chicken coop. It is also possible to add an appropriate amount of multivitamins or other anti-stress drugs to feed or drinking water to prevent and reduce the loss caused by stress response.

1 Epidemic prevention should be accurate It mainly includes the quality of the vaccine, the time and method of vaccination, and the condition of the chicken. For example, the vaccine should not be diluted with boiled or dirty water, otherwise it will lead to the failure of epidemic prevention; The condition of the chicken flock is not good, we must adapt measures to local conditions, take measures in time, and do not memorize dogma.

2 Eliminate the source of infection When chickens enter the chicken coop, they should refuse to visit, bury or burn the sick and dead chickens, and do not throw them, use them indiscriminately, or sell them indiscriminately, otherwise they will spread the pathogen and lead to the epidemic of infectious diseases.

3. Do a good job of disinfection and sanitation to frequently clean the food trough and water trough, and the feed bag should be dedicated to the special bag; Regular disinfection to remove pathogenic microorganisms from the surface of utensils and prevent diseases from entering the flock. Chicken farmers themselves should also do a good job of sanitation and disinfection.

4 Rational use of drugs Usually observe the diet and defecation of the chickens, mental status and other problems, and timely use drugs to prevent and **. In the process, the dosage should not be too low or too much, otherwise it will not achieve the best effect or cause poisoning.

5. Rational application of vitamins and other additives At different stages, reasonably equip the feed, and do not add or reduce vitamins and other additives. If vitamin supplementation is neglected for a long time, chickens will die sporadically during the growth and development stage.
