Common mistakes in the use of drugs in chickens

(1) blindly increase the dosage: most farmers think that the greater the dosage, the better the therapeutic effect, and blindly use large doses when using antibiotics. The use of large doses of drugs, some may have a certain effect at that time, but left hidden dangers.

① causes poisoning death or chronic drug accumulation in broilers, resulting in damage to liver and kidney function. The function of liver and kidney is impaired, and the detoxification function of broilers is decreased, so it is difficult to use drugs to treat and prevent diseases.

② killed the beneficial bacteria in the intestine and destroyed the balance of normal intestinal flora, resulting in metabolic disorder, increased intestinal functional diarrhea and hindered growth in broilers.

③ bacteria are very easy to develop drug resistance, but there are often some drugs that have not been used for a long time in clinic, such as ciprofloxacin, norfloxacin and so on. The curative effect of using these drugs according to the conventional dose is very poor, the reason is related to the enhancement of bacteria resistance to the drug and the emergence of drug-resistant strains.

It may be replaced in less than 2 days, which often fails to achieve the desired drug efficacy, making the disease difficult to control.

(3) the random selection of several drugs combined with reasonable drug compatibility can play a synergistic effect among drugs, but if they are blindly compatible, it will cause harm, light will cause ineffective use of drugs, and serious cases will cause poisoning and death in broilers.

(4) medication is only for treatment, ignoring the preventive effect of drugs. Many people have poor awareness of preventive use of drugs, and most of them use drugs to treat broilers when they are sick. It fundamentally violates the principle of "prevention is more important than cure". The consequence of this is that most diseases are not treated until the middle and later stage, which seriously affects the therapeutic effect and increases the cost of medication, and the economic benefit is also greatly reduced. The correct method should be: to clearly understand the local common disease, frequently-occurring disease, formulate a clear early preventive medication procedures, so as to prevent in advance and reduce unnecessary losses.

(5) regardless of the active ingredients of the drug, only use the "new drug". Clinical often encountered such a situation, after using a drug for 2 days and then switched to another drug for 2 days, achieved a very good effect, most farmers will think that the efficacy of the second drug is high. In fact, this is not the case, because the two drug ingredients are actually the same, but their trade names are different, and they only have a good effect because they have reached the course of treatment. In addition, some drug manufacturers do not indicate the active ingredients of the drug in the instructions, which leads to confusion in the use of drugs by farmers.

(6) do not pay enough attention to the safety of drugs, the safety range of some drugs is very narrow, the amount of treatment is very close to the dose of intoxication, such as Maduramycin and so on. Farmers are not clearly aware of this in use, resulting in poisoning due to uneven mixing of feed or slightly higher concentration in the process of use, which should be paid enough attention.
