In the practice of clinical diagnosis and treatment, many chicken farmers were found to have experience in raising chickens for many years. After the onset of the disease, the chickens generally purchased their own medicine, but the efficacy was not ideal. The main problems are as follows:
First, little knowledge of chicken disease, the diagnosis is not clear
Some chicken farmers have little understanding of the disease. For example, if one sees the heart of the liver, it is E. coli disease; one sees glandular stomach and nipple hemorrhage, which is Newcastle disease; cut open bowel valgus, that is, coccidia. As everyone knows, in recent years, with the gradual deterioration of the environment and the continuous evolution and evolution of pathogens, the symptoms or pathological changes of many diseases have undergone great changes. Especially mono-infected diseases are hard to see again. Farmers also look at the new situation with an old eye. It is not known that many diseases are mixed infections or secondary infections.
In actual production, the types of mixed infections are viral mixed infections, such as Newcastle disease and infectious bronchitis; viral and bacterial mixed infections, such as Newcastle disease and E. coli; bacterial mixed infections, such as chicken Escherichia coli. Disease and Salmonella; Bacterial disease and parasitic disease mixed infection, chicken colibacillosis and coccidiosis. Because of the combination of multiple pathogens, it is difficult to diagnose the disease if it is not clear whether it is the primary or secondary diagnosis, or if only one is known and the second is unknown. Once diagnosed wrongly, the effect of the treatment can be imagined.
Second, the treatment is not timely, delay the best time
After the onset of the flock, most farmers are unable to provide basic treatment for the symptoms at the first time. For example, when the spirits of the chickens were slightly worse, the stools were somewhat abnormal, and when they were eating slowly, they still did not know that the chickens had already developed the disease, and they would not even be treated with medication. When the dead chickens appeared and the deaths continued to increase, when the appetite of the chickens was greatly reduced, it was known that the chickens were infected. So rush to medication, but it is too late, the natural effect is not good.
The cost of raising chickens is a comprehensive concept, not just medicine. There are also a small number of farmers who are blindly believing that they have lost their chickens. In order to save a few drug money, they are preoccupied with drug purchases and believe that the lower the drug price, the more cost-effective. In fact, ineffective or poorly effective drugs are the most expensive. Good drugs, though expensive, are actually more cost-effective than invalid or ineffective drugs. If quality is sought, it will definitely delay treatment and it will not be possible to achieve satisfactory results.
Third, blindly mix drugs, abuse of antibiotics
The onset of fowls began to die. Farmers often used drugs indiscriminately. They not only failed to cure the disease, but also failed to obtain timely and accurate treatment. As a result, the disease was aggravated and deaths increased. For example, if the chicken has a cough, use tylosin and other drugs; where chicken diarrhea, use drugs such as renoxacin. In fact, chicken cough may not only be mycoplasma, but may also be laryngotracheitis, bronchitis, Newcastle disease, bird flu, etc.; chicken diarrhea may not only be salmonellosis, but also may be colibacillosis and various viral infections. .
It is also common for veterinarians to abuse antibiotics clinically. No matter which diseases they treat, antibiotics are indispensable. In fact, there are many diseases that do not require antibiotics at all, such as indigestion, heatstroke, and poisoning. The use of antibiotics increases the resistance of pathogens, causing disorders in the intestinal flora. Do not ask indiscriminate use of drugs, there can be no good treatment.
Fourth, premature withdrawal, resulting in repeated illness
In order to save the cost of medication, some farmers used one or two days of medicine, and the condition of chickens has improved. After a few days of illness, the illness has once again aggravated and the dead chicken has increased. This does not consolidate the curative effect, leading to repeated illnesses and even to chronic diseases. It is more difficult to cure the disease because repeated medications often produce drug resistance. Therefore, in the treatment should follow a variety of diseases have a certain course of treatment for treatment, continue to use 1 to 2 times after the symptoms disappear, to consolidate the curative effect, to cure the disease.
Fifth, do not understand the role of drugs and treatment, excessive increase in the amount of medication
There is a process, a course of treatment, for chicken disease from the beginning of medication to cure. A course of treatment usually takes 3 to 5 days. A small number of farmers are trying to get sick by increasing the amount of medication, feeding a meal or injecting a drug. This is not practical. As a result of this, it is not only impossible to cure chicken disease once, but also because of the excessive dose of drugs to the chicken population to increase toxic side effects and even cause drug poisoning.
Some chicken farmers also misjudged the efficacy. Mainly in two aspects: First, do not understand the role of drugs is to have a process. After the drug was found, the chicken continued to die or there was a short-term increase in death after the drug treatment. The drug was considered to be ineffective for one-sided use. Second, when the original drug was effective and had not yet improved, it was blindly used for other reasons. drug. As soon as the result is used, it is considered to be “spiritualâ€, and it is mistaken for the drug to be changed to be effective, resulting in misjudgment of the curative effect.
Sixth, listen to disease, prevent, see the drug
Some farmers have immunized chickens as soon as they heard that some local infectious diseases have occurred recently without conducting investigations and studies. This is likely to cause pollution on the clean farms and bring pathogens to the farms, such as bird flu and infectious laryngotracheitis. If there is no disease in this field, as long as we pay attention to disinfection, strengthen management, pay attention to the introduction of isolation observation, without unnecessary prevention.
In some breeders, when disease occurs in chickens, only pathogenic factors are treated and neglected to improve the defensive or anti-injury ability of chickens. In clinical practice, comprehensive treatment should be adopted. It is necessary to eliminate the pathogenic factors, but also to strengthen the care of diseased chickens and improve their resistance, in order to receive a good effect.
