What is the harm of using veterinary drug powder directly in the process of breeding?

In order to prevent and extract scrapie, it is sometimes necessary to add veterinary drugs to livestock and poultry feed or drinking water. In production practice, many farms often use veterinary drug powder directly, and the more large-scale farms (especially poultry farms), the more popular the use of raw powder. Farmers mistakenly believe that the use of veterinary drug powder is easy to operate, convenient and convenient, and the most important thing is that the dosage is small, the price is relatively cheap, and can effectively reduce drug input.

In fact, the direct use of veterinary drug powder in farms has many disadvantages, such as: because the pharmacology is unknown, it is easy to have serious side effects, and because the dosage is not well controlled, it is easy to lead to drug-resistant strains and bring obstacles to the prevention and treatment of diseases in the future; as the drug residue is large, it is easy to endanger food safety: because the supervision is out of control, it is easy to provide opportunities for counterfeiters and threaten the healthy development of the aquaculture industry.

1. It is illegal to use raw powder of veterinary drugs

Veterinary drug raw powder is the raw material of veterinary drug produced by veterinary drug factory, which belongs to veterinary drug raw material drug. In the finished veterinary drugs, not only raw materials, but also synergists, co-solvents, stabilizers and other components, the use of finished drugs can play the best efficacy, simple raw powder can not be directly used in aquaculture production.

Article 41 of the regulations on the Administration of Veterinary drugs (2004) issued by the State Council clearly stipulates: "Veterinary drugs that can be added to feed approved shall be made into drug feed additives by veterinary drug production enterprises before they can be added. It is forbidden to add APIs directly to feed and animal drinking water or to feed animals directly. " Article 68 stipulates: "whoever, in violation of the provisions of these regulations, directly adds APIs to feed and animal drinking water, or feeds animals shall be ordered to make corrections immediately and shall be fined not less than 10,000 yuan but not more than 30,000 yuan. If he causes losses to others, he shall be liable for compensation according to law. " Thus it can be seen that the direct use of veterinary drug powder in farms is obviously an illegal act, serious people need to bear the corresponding legal responsibility, this kind of behavior should be corrected in time.

two。 The use of veterinary drug powder is easy to produce toxic side effects.

To add veterinary drugs to feed or drinking water, it is necessary to know exactly the amount of feed or drinking water of livestock and poultry, and the relevant data need to be converted into the dosage of each livestock and poultry, so that accurate drug administration can be achieved. The raw powder is different from the finished drug and will not mark the usage of livestock and poultry, but the general veterinarians or farmers simply do not know the conversion relationship between this drug and the finished drug, let alone the pharmacokinetic parameters of this drug in livestock and poultry. In fact, it is difficult to determine the exact dosage of the raw powder, so it is potentially dangerous to use the raw powder directly in production. For example, Madurin is a univalent glucoside polyether ion carrier antibiotic, which is mainly used in the prevention and treatment of chicken coccidiosis. It has the advantages of broad spectrum, high efficiency, low drug resistance and no residue, and is widely used, but the clinical dose is very small and the safety range is very narrow. The recommended dose is very close to the toxic dose, and a little carelessness will lead to poisoning and bring great losses to chicken farms. Therefore, the production needs to choose 1% Maduramycin premix, if the direct use of Maduramycin powder, it is very dangerous; even if the dosage control is more accurate, if the mixture is not uniform, poisoning accidents will also occur.

The role of raw powder is often a single bactericidal or bacteriostatic, there is no auxiliary treatment ingredients, but now the diseases of livestock and poultry, especially infectious diseases, most belong to mixed infection, the simple use of a certain kind of veterinary drug powder for prevention and treatment, will not achieve the desired effect at all. If several kinds of veterinary drugs are used together, it can only be done by experienced veterinarians. if the general farmers mix drugs, it is easy to have incompatibility taboos, the light ones are ineffective to the prevention and treatment of diseases, and the serious ones may have toxic reactions. a serious threat to the safety of livestock and poultry. In addition, some drugs are too acidic or alkaline, the direct use of raw powder, the stimulation of the gastrointestinal tract of livestock and poultry is very large, but also easy to cause undue harm.
