The ultimate goal of broiler production is to obtain good quality food and maximum economic benefits. Therefore, it is necessary to master scientific broiler breeding management and disease prevention and control technologies, and firmly grasp several key measures in the production of broiler chickens in order to achieve the lowest Feeding costs get the best economic benefits. 1 High-quality chicks require chickens to be introduced from regular farms with good quality, high reputation, and no egg-transmitting diseases. Only healthy chickens can achieve high yields. Young chicks should be agile, with dry hair, bright eyes, and consistent development. In production practice, the survival rate is usually 7 to 10 days. If 7 to 10 days have died, the problem may come from the chicks themselves. 2 Feeding broilers with full-priced feeds must be based on quality, low cost, balanced nutrition, and comprehensive formula feed in order to achieve the desired production performance. Therefore, in production practice, we must choose carefully. Feed quality is relatively stable, and a supplier with a good after-sales service system will help you achieve your intended goals. 3 Excellent environmental environment includes both large and small environments. The environment refers to the site selection and layout of chicken farms. Chicken farms should be built far away from towns, factories and traffic routes. It is required to have a high ground and sunny, with sufficient sources of sanitation, convenient for power supply and transportation, and to be rationally laid out and constructed in accordance with the requirements of broiler production. It is recommended not to engage in large-scale centralized rearing (based on the actual situation of domestic broiler production at present), and it is advisable to implement scale diversion and engage in rearing communities. The small environment refers to the broiler's place of life. The good environment of the small environment directly affects the production of broilers. Creating a comfortable and fine environment for broilers is the key to improving the production of broilers and should be given priority. 4 Scientific Feeding and Management 4.1 Sanitization and Disinfection of Chicken Houses Disinfection tanks should be set up in front of chicken clubs. It is necessary to maintain regular disinfection of chicken coops and the surrounding environment, regularly remove chicken dung or replace litter, and insist on sterilizing chickens. Disinfectant drugs can be used Oxyacetic acid (but not long-term use of a single sterilizing drug), scaffolding or online chickens can be sprinkled with calcium hydrogen phosphate on the ground. Because peroxyacetic acid can produce a nontoxic acetic acid hinge with ammonia, superphosphate can synthesize odorless solid phosphate with ammonia, thereby reducing the ammonia content. 4.2 Breeding density New chicken farms can be reared at 8-12/m2. Older chicken farms should be kept at lower density. For chicken farms with poor heatstroke prevention conditions, the density of chickens should be reduced in the summer, and 5-8/m2 is appropriate. 4.3 Ventilation of the house Breathing and ventilation of the house can avoid various diseases that cause flocking due to air pollution in the house. For example, after 35d (or even more advanced), the chicken snoring may not be infectious, but rather it is related to ammonia. There are several ways to solve this problem: First, diligently remove chicken waste or replace litter regularly to solve the problem of sanitary problems; second, add zeolite to the feed to reduce the production of ammonia; third, open the window for ventilation during warm weather. But beware of the thief's wind is the fourth chicken house to arrange fans or implement vertical ventilation. 5 Proper use of drugs 5.1 Medications for treatment The prophylactic medications can be administered with condiments. It is best to use drinking water for curative treatment, and some injections can be used to treat some diseases in cage chickens. Freshwater should be given priority to diseased chickens to ensure that they can drink fresh and delicious drinking water, and they must be able to drink enough water to drink water. Because chickens are most vulnerable to physical weakness, they are willing to walk around, and when it is most difficult to get water, it is not easy to recover. So do everything possible to make chickens drink fresh water before they recover. 5.2 To solve the problem of insensitivity between drug susceptibility testing and clinical application, there are several reasons for this. One is that the drug test bacteria are not pathogenic chickens; the second is the use of a drug sensitivity test paper of different quality (national Targeted production will generally have no counterfeit products. Third, the amount of potable drugs can be used in actual production (because of the lack of actual drug content of many veterinary drugs on the market), it is best to experiment with drugs in chicken farms. 5.3 Reducing the cost of medications Deeply into practice, careful analysis, symptomatic drugs, and doing everything possible to reduce the cost of medication. 5.4 Prevention of drug poisoning is mainly caused by an overdose of drugs (such as furazolidone, sulfa drug poisoning, etc. Secondly, human medicine is caused by veterinary use; thirdly, it is caused by repeated medications; and fourthly, the effects of drugs are unknown (such as oral rehydration). Salt can not be used in physiological thirst); five is the calculation error and drug contraindications (such as the net of Zhiyuan is not combined with salinomycin, monensin, and furazolidin can not be used together with dinitrotoluene.) 6 Correct use Vaccine 6.1 Prevent Interferon Interference The interferon interferes most in 2 to 3 days and disappears in 7 to 10 days, so it is necessary to arrange immunization according to production, to avoid interference between vaccines, and to influence the immune effect.Newcastle disease and infectious bronchitis are Can not be immune for a few days before or after 6.2 Preventing the death of live vaccines Mainly pay attention to the transport of vaccines, the death caused by disinfectants and the death caused by the effects of antibodies 6.3 Choosing the right vaccination method Select the appropriate vaccination method according to the immunization procedure: nasal drops, eye drops, drinking water Or injections.Immunization is best done without the occurrence of infectious bursal disease.The drinking water should pay attention to the pH of the water between 6.8 to 8, the amount of water should be appropriate The water tray should be sufficient, skimmed milk powder should be added to the water, and the drinking should be repeated 2 times.
