Management plan for broilers during exchange in summer and autumn

1, temperature is one of the main factors in the brooding stage, the appropriate temperature can play the biggest benefits of feed. Low temperatures can cause chickens to develop respiratory illnesses and deaths. Judgment methods are: First, the thermometer is hung at the same height as the chicken temperature measurement, the first week of autumn and winter brooding generally controlled at 35 °C ~ 36 °C, after the weekly reduction of 2 °C ~ 3 °C, the second is based on the chicken's reaction, This is also a problem that the farmers should pay attention to. When the temperature is too low, the chickens scream and pile up. When the temperature is too high, the birds are dispersed and have wheezing. The temperature is suitable for even distribution of chickens. It is also possible to use a thermometer and sensory combination to determine if the temperature is suitable.

2. For broiler feeding, special attention should be paid to dry and clean litter. During the brooding period, it is best to use a straw as a litter, which is more dry and conducive to raising the temperature; in the medium-sized chicken stage, the temperature should be increased when the temperature is lower than 18°C.

3, chicken house fresh air, can avoid the occurrence of respiratory diseases. Harmful gases or dust in the air can affect the health of chickens and even cause death. The anaerobic bacteria in the shed decompose fecal matter and nitrogen-containing organic matter to produce ammonia gas. When the ammonia concentration in the house is 1510-6, people feel uncomfortable. Therefore, the ventilation should be reduced without reducing the normal room temperature, and the harm in the chicken house should be reduced. Gas and dust content.

4, reduce stress response. Too loud voices, transfer groups, vaccination, sudden changes in the weather, and severe deafness are unpleasant stimuli to chickens and can often cause morbidity. Avoid unnecessary catching and disturbing as much as possible during feeding. Anticompetitive drugs should be given for prevention before transfer, vaccination, and debridement; the cold stress caused by the temperature drop should be handled well.

5, the density exceeds the General Assembly caused by unbalanced growth of chickens, harmful gases in the air increased, especially in the autumn, humidity, chickens are susceptible to E. coli, coccidiosis, staphylococcus, etc., and can make the disease faster. Therefore, broilers are generally controlled at about 10 per square meter.
