I. Acute infectious diseases
Chicks are fed in large groups and under confined conditions, the chicks are very susceptible to diseases, especially infectious diseases that are more difficult to control in the clinic, such as Marek’s disease, Newcastle disease and infectious bronchitis. At present, there are no effective drugs in actual production that can treat such infectious diseases. Therefore, it is more effective to vaccinate chickens. Different chicken farms must develop an immunization program suitable for this field against the prevalence of epidemics on the premises or in the region and the types of microorganisms present. When chicks are introduced, they are required to provide immunization programs and are effective immunization programs. In the introduction area, if there is no epidemic of an infectious disease, it is temporarily possible not to vaccinate the flock.
Second, the chicken bacillus disease and coccidiosis
Among the reasons for the death of chicks, white bacillus disease and coccidiosis are the main influencing factors. Chicks up to 21 days of age can add 0.05% oxytetracycline to their feed, which has a preventive effect on the occurrence of bacillus disease. Chickens over 15 days of age should be protected against coccidiosis, especially when the chick population is kept in a high density and in a warm, moist environment. The chicken must be given drug protection. Maduramycin can be added to the diet. Chlorobenzene muscle amount. When the drug is used, it must be accurately weighed and evenly stirred to avoid the occurrence of drug poisoning in the chick. One drug should be replaced with another new drug after 1 to 2 months to avoid the emergence of drug resistance.
Third, respiratory infections
In the brooding stage, if the insulation effect is poor and the room temperature is not high, the chicks can only maintain the balance of body temperature in a short period of time, and are prone to cold and infect respiratory diseases. If the temperature in the brooding room is too high, ventilation of the doors and windows can easily cause the chicks to become infected with respiratory diseases.
The air in the brooding room is not fresh, the ventilation and ventilation conditions are poor, the temperature is not constant, the damp and contaminated bedding and the moldy and deteriorating feed are used to feed the chicks, and it is easy to infect respiratory diseases. The temperature of the brooding season will be affected by the season, climate, type of brooder, broiler constitution, and age, so it should be adjusted flexibly according to specific conditions. The temperature should be ensured, but also pay attention to ventilation, avoid thieves and drafts to avoid the chicks directly by the wind. Humidity has a significant effect on the growth and development of chicks. The relative humidity of the brooding room is maintained at 60% to 65% for 10 days before brooding.
Insect net greenhouse also known as plant and vegetables greenhouse net. Used for prevent the insect fly into the greenhouse during the plant growing, and cover the plants. Key off the approaches that the pests (adult insect) breeding. Effective control of the spread of all kinds of harmful pests spread, such as Cabbage caterpillar, diamondback moth, aphids, flea beetles, Sweet agnates, American leaf miner, literal etc and prevent the harmful of virus spread. Significantly reduced the use of chemical pesticides, so that the planting vegetables good-quality and health.
