Principles and common sense of necessary medication in large-scale chicken farms
Classification:
With the development of society, the domestic large-scale breeding industry is also going hand in hand, the breeding density is increasing, and the overall environment of the breeding industry is also deteriorating, making the incidence of various diseases more and more frequent. The disease is also more diversified and mixed, which makes the treatment complicated. We advocate prevention over cure for chicken diseases, but we must use drugs rationally when we must treat them.

The disease is also more diversified and mixed, which makes the treatment complicated. We advocate prevention over cure for chicken diseases, but we must use drugs rationally when we must treat them.
1. Understand the common sense of disease and prone time, timely prevention
Large-scale chicken farms should pay attention to cost savings when considering disease prevention and control. Therefore, it is necessary to master the time and law of the disease, so as to prevent it in a timely and appropriate manner. For example, the threat of pullorum in chicks within 2 weeks of age is greater, so the early stage of brooding is mainly to prevent pullorum. Medication prevention of coccidiosis should be done well at the age of 3~7 weeks. Intermittent alternate medication prevention; In early winter, the climate changes greatly, and chickens are prone to respiratory diseases and colibacillosis. At this time, besides strengthening feeding management and disinfection and epidemic prevention, drug prevention should also be done in advance.
At the same time, we should pay more attention to the management of chickens, ensure the supply of nutrition, enhance the collective immunity of chickens, and make the drug play an effective therapeutic role.
2. Diagnosis of diseases and scientific methods of medication
When the disease occurs, the diagnosis should be timely and the cause of the disease should be accurately identified. Grasp the indications of commonly used drugs and use them correctly in combination with the situation of the field, and avoid the long-term use of the same drug to avoid the occurrence of drug resistance.
2.1 usually, if there is no disease in the chicken farm, do not use drugs without purpose or pertinence, otherwise it will lead to the increase of drug-resistant strains and be helpless in the key treatment.
When individual chickens in 2.2 large-scale chicken farms are sick, do not overdose the whole group for a long time, so as to avoid damage to the internal organs of the body or metabolic disorder, affecting development.
2.3 do not blindly use a variety of drugs to affect efficacy.
2.4 the right remedy.
2.5, the mode and time of administration should be determined according to the rules and parameters of drug metabolism in vivo.
3. Reasonable grasp of drug usage
3.1 drinking water administration. Pay attention to the solubility of drugs. For insoluble drugs, heating, stirring or adding cosolvents can make the concentration meet the requirements. Pay attention to the influence of water quality on drugs. Too hard water quality, partial acid and partial alkali will affect the drug effect. Clear the administration time of drinking water, prevent water cut-off, and try to finish drinking within 2~3 hours.
Administration of 3.2 mix. To accurately calculate the dose of drugs to prevent poisoning. Stir evenly, while preventing the resistance of certain ingredients in drugs and feed.
Administration 3.3 injection. Common ways are subcutaneous injection, intramuscular injection. The site is often chosen where there is more muscle and less blood vessels, especially in the treatment of severe dying chickens.
3.4 spray administration. The lungs and air sacs in the respiratory system of chickens cooperate closely, so the air sacs can increase the area and scope of drug diffusion and increase the absorption of drugs by chickens.
4. Understand the quality of drugs, side effects and compatibility
The use of drugs in large-scale chicken farms should be scientific, time-sensitive and economically shared. The treatment of diseases must consider the cost, choose those effective and inexpensive drugs that take into account the economic benefits of large-scale chicken farms. At the same time, chicken farms should cooperate with disinfection and epidemic prevention, and strengthen daily management. Always remember the principle that prevention is more important than cure. Strengthen epidemic prevention, eliminate the source of disease, so that their large-scale chicken farms continue to grow.
5. Use of disinfectants in large-scale chicken farms
Disinfection is particularly important for large-scale chicken farms. If the virus and bacteria content in the chicken coop reaches the pathogenic quantity, the chickens will become ill. Therefore, disinfection of chickens in the environment can effectively reduce the harmful pathogens in the coop, thus ensuring the safety of the chickens.
The selected disinfectant should select different types of disinfectants for different pathogenic microorganisms, for example, all disinfectants have no effect on coccidia and blastospores. Practice has proved that every 2 to 3 days disinfection in turn is the best disinfection frequency.
