On August 2nd, 2008, a chicken farmer took help from the two dead chickens for help. He told him that he had bought 1,000 fine breed eggs from a certain kind of farm 23 days ago and was kept indoors for 20 days. His growth and development were in good condition. Because of the narrowness of the site, the chickens were raised in the mountains. One day later, the chickens became sick.
The new site is 4 kilometers away from the original house, and the connected tractor road was destroyed by heavy rain. Even motorcycles could not go up. There are several simple bamboo sheds in the new farm, one for the breeder's house, at the highest point, about 3 meters away for the chick shed, followed by several spare chicken sheds.
In the chicken shed, the sick broiler has a low body temperature, is depressed in spirit, and some perianal mucous membranes are filled with feces. Occasionally feces are entrained with blood. The use of detoxification, anti-bacterial, anti-inflammatory and anti-TB drugs for raising chickens had no effect. In the past few days, 120 birds were killed and there were several dozen chickens in the isolation shed.
Anatomy shows heart and hepatomegaly, bursae congestion and edema, and some of the posterior intestine is filled with water-like dilute feces, foot scales without bleeding, no conjunctival inflammation, no other organs have obvious lesions.
It is understood that the new site during the daytime temperature above 30 °C, sometimes lower than 13 °C at night, the temperature difference between day and night up to 17 °C, high and low temperature caused great harm to the chicks.
The chicks were defrosted on the 20th day without a one-week transitional period. Shortly after the transfer to the new chicken farm, it hit a heavy rain. Drainage was poor around the chicken shed and the relative humidity was too high. The ground is raised flat, and there are holes in the chicken sheds. Some chicks drilled out of the sheds and dipped in the grass to wet the feathers, reducing the resistance.
The diseased chicken has a low body temperature, no bleeding on the foot scales, no conjunctival inflammation, and can eliminate the infectious diseases such as bird flu. Therefore, it is diagnosed as a chicken adverse environmental syndrome.
Emergency treatment, strengthen the night insulation. Prepare several small iron drums with a diameter of 20-30 cm, cut a hole in the bottom of the bucket, and hang a 100-watt incandescent light robe in the iron drum. Insulate it when the temperature is low.
Move into a new shed. The people who live in the relatively high-drying sheds were selected to disinfect the site first. The ground was covered with a thick layer of dry, mildew-free straw. The roof was covered with firewood to enhance insulation and heat protection. The shed is equipped with movable thermal insulation stickers. When the shed is removed, plastic nets are used to stop both sides of the road and the chicks are slowly driven into the new shed.
Pay attention to the condition of the flock. If the chicks gather and play together, then the heat preservation is strengthened. When the chicks are separated from the mouth, the drinking water is significantly increased, and the heat is reduced. When the smell is unpleasant, attention should be paid to ventilation to eliminate harmful gases and ensure the oxygen demand.
Upon disposal, the diseased chicken no longer died and gradually returned to normal.
Although efforts have been made to recover the losses, there are still significant risks. For this breeder, it is very difficult to create an environment suitable for the growth of chicks in the short term. Therefore, a similar situation has emerged. It is suggested that measures should be taken to suit local conditions, minimize the scale of production in the initial stage, and replace the chicks that have been separated from the temperature and have enough age to adapt to the mountain climate.
