Six Problems to Be Paid Attention to in Chicken Breeding
Some chicken farmers lack regular pharmacological knowledge and there are many problems in drug selection and use that affect the control of disease and the healthy growth of chickens. The main points of using chicken medicine are as follows: First, the general principle of choosing drugs. Before selecting drugs, accurate diagnosis of the cause of chickens should be conducted. According to the advice of veterinarians and technicians, a veterinary drug business unit with guaranteed quality and good reputation should purchase drugs, and pay attention to the production lot number, production site, production date or shelf life of each drug package. As well as the instruction manual, it is forbidden to purchase “three nos†or expired drugs. Second, the correct identification of different formulations of the appearance of drugs. 1 The appearance of the tablet should be completely smooth, uniform in color, with appropriate hardness, no black spotted spots, no broken, sticky, discolored, and odorless. 2 powder injection agent to observe whether there is a sticky bottle, discoloration, agglomeration, deterioration and so on. 3 The liquid injection solution must be clarified, and there should be no turbidity, discoloration, crystallization, and long bacteria. 4 Chinese herbal medicines to see if there is moisture absorption mildew, insects, rat bites and so on. Third, rational drug use. Correct diagnosis of the disease before medication and targeted administration. Some chicken farmers lack understanding of this and neglected the importance of correct diagnosis. When a chicken becomes ill, it is used. When one of the medicines is not effective, the other is replaced. When another is invalid, the dressing is changed again. This treatment method is mostly unsuccessful. of. In addition, some chicken farmers are very serious in their abuse of drugs. They are taking drugs every day in drinking water and feed, preventing disease, and redouble their dosage. This method of administration not only increases the cost, but also causes dysbacteriosis in the digestive tract of the chicken, destroys the balance of the body, and reduces the resistance of the chicken. Fourth, according to medication medication. Use any kind of medicine must have a certain course of treatment, usually 3 to 5 days. If the medication is short, the pathogens in the chicken are only temporarily suppressed and not killed at all. Once the medication is stopped, the inhibited germs will re-grow and multiply, resulting in more serious clinical symptoms. Some chicken farmers have problems in this area. If they do not use drugs for less than 2 days, they will switch to other drugs if they do not work. This will lead to a short course of treatment that will prevent the drugs from exerting their normal effects. Fifth, medication and management. At the same time as medication, it is necessary to improve the husbandry and management and to make the sanitation and disinfection work. The treatment of chickens when they are ill is only one aspect of controlling the epidemic. On the other hand, there is still need to improve the husbandry management and sanitation work. Some chicken diseases are caused by mistakes in feeding and management. If feeding and management do not improve, the incentives for the onset of chickens still exist, and it is difficult to obtain good curative effects. Only the chickens do not die during the administration period. After stopping the medication, the chickens are again Initiation of death. In addition, during the onset of the disease, chickens and excreta continue to expel pathogens and contaminate the living environment of the chicken. If the chicken is not sanitized, the chicken is contaminated by the pathogen. When treatment, chickens kill pathogens due to a certain drug concentration in the body, and the chickens can die without stopping the disease. After the drug is stopped, the drugs in the body are quickly excreted. When the chickens come into contact with pathogens, they are quickly infected again. This is why the average person said that the curative effect is not strong, the chicken does not become ill when administered, and the reason that the chicken begins to develop again after stopping the medication is several days. Therefore, when a chicken is ill, it cannot rely solely on drug treatment. It must also improve feeding management and sanitization, so that chickens no longer have to contact pathogens, so as to consolidate the curative effect, and chickens will no longer die after stopping the medication. Six, the limitations of drug treatment. There are many causes of chicken disease, including management reasons, such as excessively high or low temperatures, high density, etc.; reasons for feed nutrition, such as inadequate feed nutrient prices; parasite causes, such as coccidia, Aphids, etc.; Bacteria, Salmonella, Pasteurella multocida infection; Viral causes, such as Newcastle disease and Marek’s disease. Drugs can play a therapeutic role. They are only caused by bacteria and parasites. They are ineffective for the treatment of diseases caused by other causes. Some people think that if chickens eat a little medicine, they can prevent and treat diseases. This point of view it is wrong. Drug treatment is not a panacea, it is only a part of prevention and treatment of chicken diseases, can not use medicine to replace other preventive measures, such as injecting vaccines, regular disinfection, strengthening feeding management, etc., we must strengthen the "prevention and treatment" idea.
