1. Example: A farm at Junying Village, Xuting Township, Zanhuang County, Shijiazhuang City. After entering the chicks, everything was normal. At the age of 15 days, some heating equipment was stopped. After that, some chicks appeared mentally ill, feed intake, and drinking water. The amount has decreased and it has begun to die. At the highest, it killed more than 40 people a day. After understanding the basic situation, the author immediately dissected 11 dead chicks and found that the body was severely dehydrated, wasted, there was no feed in the crop, intestinal thinning, almost no feces in the intestine, no bleeding in the trachea, bronchus, blood stasis, glandular stomach nipple There was no bleeding point. There was no hemorrhage in the intestinal wall. There were no hemorrhagic spots in the leg muscles or pectoral muscles. The reason why the chicks of the farm died was due to improper temperature control. 2. Measures: Rapidly increase the temperature to 28 ~ 30 °C, drinking water to join the source of life and oral rehydration salts for their free drinking, 5 days after the return visit except for a small number of chicks died, the rest returned to normal. 3. Reminder: The appropriate temperature is the primary condition for ensuring the survival rate of the chicks and must be done carefully. Freshly hatched chicks have poor body temperature regulation and their body temperature is 3°C lower than that of chickens. They begin to increase until 4 days of age, and they reach the body temperature of chickens at 10 days of age. Because the chicks have short fluff, poor cold tolerance, low feed intake, and low calorie production, they cannot maintain physiological needs. Therefore, the chicks must be bred to the proper temperature required by the chicks during the brooding period.
