Choose a suitable health care drug for chicks

The chicken rearing period is an important stage of the whole chicken life cycle. If the chicken health care is done well in the chicken stage, then the feeding and management in the later stage will be much more smooth. How to choose open-mouth drugs in the chicken stage? At present, there are roughly the following types of oral drugs used in clinic:

1. Disinfection and antiseptic. The representative of this kind of common drugs is potassium permanganate. Potassium permanganate is a kind of strong oxidant, which mainly has the function of sterilization and deodorization. Potassium permanganate is mainly used in the recurrent epidemic situation of infectious diseases that are difficult to eradicate, or the epidemic alarm has appeared in the surrounding farms, which need to cut off the route of transmission, or the breeding conditions are poor, and the management is not in place. The method of administration is drinking water, which is often prepared into 0.05% 0.1% solution and used continuously for 3-5 days. Attention should be paid to the use of this kind of drugs: the appropriate use time is 3-5 days, and the preventive effect on non-intestinal infection is not obvious.

two。 Antibiotics. The use of broad-spectrum antibiotics is a common method at present. Commonly used drugs are penicillins (compound amoxicillin, etc.), aminoglycosides (gentamicin sulfate, amikacin, etc.), fluoroquinolones (enrofloxacin, etc.). The opening of antibiotics has unparalleled advantages, such as compound amoxicillin can absorb blood and has a better preventive and therapeutic effect on bacteremia and septicemia. However, antibiotics also do some damage to the body, especially in chicks. Some antibiotics have poor absorption, such as aminoglycosides, which have high intestinal concentration after oral administration, which can not only kill pathogenic microorganisms, but also affect the reproduction of probiotics in the intestine. therefore, it is not recommended that such drugs should be used for a long time or in large doses. In addition, antibiotics are easy to produce drug resistance, and the cost is high.

3. Traditional Chinese medicine. At present, traditional Chinese medicine is mainly to improve the self-immunity of chicks, in order to make chicks strong and maintain high resistance to diseases. Astragalus polysaccharides is the representative of this kind of drugs, mainly to enhance non-specific immunity and humoral immunity, and has an antagonistic effect on immunosuppressants.

4. Microecology. This kind of drugs can not only avoid the disadvantages of the first three drugs, but also recuperate the intestines in the chicken stage. The introduction of intestinal probiotics in the chicken stage can make it propagate in the intestinal tract early, and the establishment of a healthy microecosystem at the first time can make intestinal diseases rare in the later stage. Practice has proved that the earlier the establishment of microecology, the smaller the probability of intestinal diseases in the later stage. However, microecological open-ended drugs also have disadvantages, mainly in that the product microecological strains generally do not survive for a long time and have a short shelf life; probiotics in microecology may interact with antibiotics in feed.

5. Nutritional additives. This kind of additives are mainly vitamins, minerals, amino acids and carbohydrates. To some extent, the addition of this product can enhance the metabolism of the body and enhance the disease resistance of chicks. But under normal circumstances, the chicks themselves have yolk sac to provide a variety of nutrients, generally do not need additional supplement, too much supplement will also break the physiological balance, resulting in certain side effects. In addition, rich nutrients added to drinking water not only provide nutrition for chickens, but also provide conditions for the growth and reproduction of bacteria, drinking water is very easy to breed bacteria, poor management is easy to cause large groups of digestive tract problems.

In addition, the effect of drug health care is also closely related to feeding management, the same health care scheme, good management can double the opening effect of chicks, while poor feeding conditions, backward management will greatly reduce the effect. In a word, each chicken farm should choose its own opening medicine and health care plan according to its own management, breeding conditions, surrounding environment, disease epidemic characteristics and other specific conditions.
