Cold weather in winter, farmers in the process of raising broilers, if you do not pay attention to cold and warm can easily lead to slow growth of chickens, while causing disease. In winter, in addition to actively storing sufficient amounts of chaff and fuel (raw coal 1.5 tons/thousand chickens), buying blankets and films for building insulation sheds, storing disinfectants, Chinese herbs, etc., what measures should be taken to manage the chickens? Making a Chicken House Environment After a long summer and autumn festival, the house is surrounded by weeds, filled with feathers and littered with chicken manure. Many bacteria and viruses are hidden in it, posing a great threat to the
Healthy growth of chickens. Before winter, the weeds and chicken excrement around the sheds were cut off and burned in a concentrated manner. Sunny days were disinfected with 2% caustic soda. Clear the drainage ditch around the house. Thoroughly disinfect the chicken house, build a disinfection tank that is not open, and replace the disinfectant every 2 days. Do a good job of insulation work to increase the insulation properties of the chicken house, reduce the loss of heat. 1 Take a heat preservation shed by taking more than 8 wires of agricultural film, thick-colored cloth or double-layered roof to reduce the loss of heat. 2 The inside of the northern wall of the house is painted to reduce the entry of cold wind. Choosing the right insulation method will not only have better insulation effect, but also save cost. 1 Selecting high-quality pulverized coal or lump coal is better than using honeycombed coal for thermal insulation. First, the heat is large, and the second is low cost. 2 The price of lump coal is higher than that of pulverized coal by 100 yuan/ton. If pulverized coal is added into a little yellow mud to form blocks, it can also be used as lump coal. According to observation, the heating effect is almost the same, but the cost can be saved. Now. (3) The use of coal with high ignition-prone coal and high ignition point can achieve the purpose of easily catching fire and burning, and the effect is excellent. (4) Honeycomb briquettes, which are not mixed with yellow mud, are easy to catch fire, easy to slag, and easy to operate. The effect is the same as that of coal. How to control the temperature: 1 According to the temperature requirements of each growth stage of the flock, supply the temperature: generally say the first week of 31 ~ 33 °C, after the weekly cooling 3 °C, after 35 days of age to maintain 18 ~ 20 °C, until the market . 2 Don't increase the temperature by sealing the chicken house. This temperature, at the expense of the air quality of the house, will only lead to poor air in the house and can easily cause the disease. 3 The increase in temperature inside the house must be achieved by burning coal. This warming does not reduce the air quality of the house and, of course, it does not induce the onset of the flock. 4 When the temperature is high, coal burning is stopped. When the temperature is low, coal must be re-burned. Dealing with the relationship between insulation and ventilation, cold-day chickens, ventilation and heat preservation are equally important. If blindly stressing insulation and neglecting ventilation, it will lead to the following consequences: air pollution inside, heavy smell of ammonia, strong odor, Respiratory diseases, renal transmission, bursal disease, and E. coli often visit the flock, and there are a large number of dead chickens and chickens do not eat long. Therefore, if you want to raise chickens in cold weather, you must deal with the relationship between insulation and ventilation, so that the coop maintains a good temperature while maintaining good air. For this reason, it is recommended to do the following: Wow coal: only more coal Furnace, add a large amount of coal, so that the temperature inside the house can be raised enough to open the window slightly in order to fully enter the fresh air, a large number of exhaust emissions. Pay attention to seize the opportunity to change the air: When the chicken is cold, it is often when sleeping. If the chicken is in motion, it is not easy to be cold when eating, and you can use good opportunities for adding coal, feeding, removing manure, and sunny days, and increase Ventilation volume (ie increase the cracks in the insulation shed) in order to fully discharge the exhaust gas and put fresh air. According to different weather to master the ventilation: winter and spring are usually the following types of weather: low temperature and rainy days, foggy days, dry north wind days, windless sunny days, generally speaking, encountered low temperature, rainy and foggy days, this is a chicken house The exhaust gas inside is particularly difficult to discharge. It is necessary to increase the amount of coal burned, expand the air outlet, and discharge the exhaust gas. If the dry wind falls on the north, the temperature in the house is low and the air convection is large. Therefore, the exhaust gas in the house is very easy. At this time, even if the exhaust outlet is properly reduced, the air quality in the house will not be affected. The hazardous gas in the well-managed shed is produced by the fermentation of moist litter. Controlling the temperature of the litter greatly reduces the generation of harmful gases. Therefore, the litter management in winter and spring should pay attention to keep the dry cleaning of the litter and a certain thickness, generally 5 cm; diligently clean up the wet litter, reduce the production of waste gas, generally 7 to 10 days once, clean up when the disease occurs; in the bucket In the most wet place around, sprinkle lime; unclog the drain outside the house to make the house dry; if you come across a rainy or wet chicken house, sprinkle evenly on the chicken padding. Calcium phosphate can play a good deodorant effect. Square meter, summer 8~10/m2. At the same time pay attention to ventilation, keep the air inside the house fresh, the temperature is about 18 °C, relative humidity of 55% is appropriate.
Chongqing has a history of
more than 1000 years of planting oranges. There are many kinds of navel
oranges, such as Newhall ,Qinqiu, Mingrijian, Changyexiang. etc. which taste
