(1) The brooding temperature required for the first week of broiler chicks is 33-35C, and the weekly change in temperature is 2 to 3C depending on the growth and development of the chicks. In addition to observing the thermometer, it is more important to observe the mental status and activity performance of the flock. When the temperature is appropriate, the chicks are evenly distributed in the brooding room, lively and active; the appetite is good; when the temperature is too high, the chicks keep away from the heat source, open their mouths, increase the amount of drinking water, and reduce appetite; the temperature is too low, the chicks are crowded and crowded, and the heat source is close to the heat source. , And continue to issue "call" calls, eating less.
(2) The so-called "de-warming" is the brooding room to stop heating, also known as off the temperature. The specific temperature of the chickens should be controlled according to the brooding season, the health of the chicks, and changes in the outside temperature. Generally early spring, late autumn and winter brooding can be defrosted at 4 to 6 weeks of age, brooding in late spring, early summer and early autumn. They can be defrosted at 3 to 4 weeks of age and brooded in summer. It is only necessary to heat several times early and late. When the temperature is defrosted, there must be a transition time. You can warm it up at night and warm it up at night. If you do not warm it on sunny days, warm it up when it's cloudy or change. Gradually reduce the number of warming per day, and finally achieve complete de-warm. The general temperature transition period is about 1 week. During periods of poor flock or epidemic prevention, deferment should be delayed. During the de-warm period, keepers must always pay attention to inspections and observations of the flock at night to ensure safe temperature release. After degassing, the room temperature is preferably maintained at 20-25C, so that the feed utilization rate can be greatly improved.
