Feeding management points
Do a good job in ventilation, to maintain a relatively stable temperature difference between day and night, usually pay attention to the weather forecast. When the temperature is high, strengthen the ventilation and cooling. When the temperature is low or when the cold current arrives, pay attention to close the doors and windows, and avoid the severe fluctuation of the temperature in the house.
Make appropriate adjustments to the light In the fall, the natural daylight hours are gradually shortened. To ensure sufficient lighting time, turn off the lights in the morning and evening, turn on the lights early in the evening, and turn on the lights properly when the light is too dark during the day to ensure the inside of the house. Appropriate lighting length and intensity.
Appropriate adjustment of feed formula With the gradual decrease of temperature, the feed intake of chickens will gradually increase, and the amount of corn and other energy feeds should be appropriately increased to reduce the amount of protein feed such as soybean meal.
In order to prevent the breeding of fly maggots and improve the air quality in the house, diligent excrement can be excreted once a day to 2 days, and can be cleaned once or twice a day with automatic excrement.
Disease prevention
First of all, we must do a good job in environmental sanitation and do a good job of daily disinfection inside and outside the chicken house.
Common diseases such as fowlpox, Newcastle disease, bird flu, infectious laryngotracheitis and other diseases of laying flock in autumn and winter are prevented by vaccines in advance.
In the fall, we must pay attention to the elimination of mosquitoes and flies to prevent mosquito-fly disease. Doors and windows are screwed on gauze nets, and insecticides are regularly sprayed inside and outside to eliminate mosquitoes and flies.
At the beginning of autumn, the air is humid and stuffy. Layer chickens often have intestinal diseases such as necrotizing enterocolitis, ulcerative colitis, etc. In addition, infectious rhinitis may also occur. Therefore, during this period of time, it may be added to feed or drinking water. Drugs for prevention, depending on the circumstances can use 2 - 3 courses, 4 days - 5 days.
In autumn, due to the gradual decrease in temperature and large temperature difference, the cold currents invade from time to time, and the autumn winds are numerous. The respiratory diseases of laying hens are frequent and easily transmitted. Therefore, in addition to strengthening the feeding and management, the common diseases are also subject to drug prevention. In the event of severe climate change, in addition to the opening and closing of doors and windows and other measures to ensure the relative stability of the temperature inside, but also appropriate drug administration, prevention of disease-prone drugs.
When a nearby infectious disease occurs, it can be appropriately prevented by drugs, in addition to necessary emergency inoculations for certain diseases.
In the case of leukocyte protozoa, which occurs in autumn, drugs are usually used for prevention. They can be used continuously, or they can be used for 4 days to 5 days each time. The interval between 5 days and 7 days is the next time, preferably 2 types - 3 Different kinds of drugs are used interchangeably.
