In autumn, the temperature gradually decreases, the temperature difference between day and night is large, respiratory and insect-borne diseases such as white-crown disease and fowlpox occur seriously, and there are new features in management. 1. Do a good job of ventilation management. There is a large temperature difference between day and night in autumn, and in the premise of keeping the air fresh, pay attention to the weather forecast and do a good job of opening and closing windows and doors in time. In principle, the front and rear doors and windows should be staggered to prevent drafts. Afterwards, the windows can be closed or fully closed. If the front doors and windows are not frozen, they should not be closed. After closing the front and rear windows and doors, be sure to open the windows and skylights to form convection. We must do a good job in the maintenance of the hen house, repair the windows and doors, damaged walls, etc., and prepare for the winter. 2. Make a good feed formulation adjustment. Based on the summer formula, when the intake of red and white chickens rises to 115 grams and 110 grams respectively, the soybean meal can be reduced by 1-2% and the corn by 1-2%. For red chickens, for example, 63-64% of Mahe LC65 corn, 23-24% of soybean meal, 5% premix, 8% stone powder; when using LC65A 20% soybean meal to strengthen the above products, 66-67% of corn 20-21% of soybean meal, 5% of premix, and 8% of stone flour. When replacing the new corn, additional high-quality vegetable oil is added according to the moisture content of the corn to offset the high energy content of the water content. In general, when the corn contains 15%, 16%, 17%, and 18% water content, the total amount of feed oil per ton is 5 , 10, 15, 20 kg, otherwise the hens consume fat for egg production, the egg production declines, and the disease resistance decreases, especially on the upper peak chicken. 3. Do a good job of sanitation. Many weeds in autumn have become habitats for wintering pests such as mosquitoes and flies. Therefore, weeds should be thoroughly removed before entering the winter, and the inside and outside of the house should be thoroughly disinfected. 4. Elimination of the oligo-chickens. In the fall, low-yield, non-producer chickens begin to moult, and we have to select and eliminate the flocks, and we will eliminate them once a month. 5. Do a good job of lighting management. Autumn lighting time is gradually shortened. Under natural conditions, the production of first-time chickens tends to be delayed. For this reason, the weight should be increased in time after reaching the target weight. For laying hens, the lighting must be kept constant, and light should be added at about 12 o'clock in the evening in summer. To gradually add the time to the morning, generally turn off the lights early, turn on the lights early, turn off the lights at 9:00 in the evening, and turn on the lights at 4:30 in the morning. Qin Qin Qin Qin, early feeding premature delivery. 6. Do a good job of preventing diseases. According to different situations in the north and south, between September 10 and October 1st, if more than 100 days of laying hens are immune to Newcastle disease-H9 double seedlings more than 70 days old, they should be uniformly immunized against Newcastle disease-H9 oil seedlings. 0.7 ml/body, preferably at the same time Newcastle disease four series 3-4 times the eye, after immunization interval 10-15 days uniform immunity H5 oil seedlings. Fall is a period of high incidence of fowlpox and white-crown disease. It is best to use U.S. and protozoan insects every month for 7 days after September and 10 to 15 days for 7 days. For the death of white crown disease, blood worms can be used (Benier, the effect is good, does not affect the production of eggs) 300 adult chickens per bottle of drinking water for 3-5 days. Fowl pox often occurs when the temperature drops to around 16 degrees, for chickens after 250 days of age. Can be re-immunized chicken pox before September 15, after the onset of treatment can use 2-3% Houttuynia mixture.
