With the development of large-scale layer production, brooding temperature has always been a problem for everyone, so let's communicate the brooding temperature with everyone next! Strictly speaking, the brooding temperature should be0age temperature and1Age temperature! The so-called0The day-old temperature is the temperature before the chicks enter the house. chicks in1-2age thermoregulatory function is poor, and1Age temperature is also related1age-related weight, for this0Age.1The age temperature specifically includes these parts:
First, in late autumn, early spring and winter in the north (the highest temperature in the day is16℃The following) it takes two days to warm up the chicken coop in advance and one day in summer. During the preheating process, the temperature in the house needs to be raised to the highest30Above the temperature and keep the temperature until the cage and bedding in the house (brooding cloth, kraft paper bedding is mainly to prevent uneven temperature from cooling chicks, promote feeding, reduce omphalitis and peritonitis at the beginning of laying, promote yolk absorption, and improve uniformity of chicks.) The wall surface temperature is consistent with the temperature inside the house.
Before the second chick enters2Reduce the temperature in the house28Degree (28Degree is the critical temperature of temperature and humidity synergy), it is OK to enter the chicken house directly after waiting for the chicken to come, which can better adapt the chicks to the temperature environment of the brooding house and effectively relieve the stress caused by long-distance transportation on the chicks;
In the third step, after all the chickens are moved into the brooding house, the chickens are gradually put into the brooding cage according to the sequence before and after entering the house, and the temperature of the brooding cage is gradually increased at the same time. Do not raise the temperature too fast, which is easy to bathe after the water level is prepared too quickly. General needs3-5Hours This depends on the number of broods and the speed of operation. The time is not easy to be too long. After all the chicks are in the breeding cage, put the water line (with water cup)1.5After the water dispenser, the material line and the material barrel are gradually filled in place, the temperature will be gradually raised to within two hours.5-10%The chick has a mouth opening phenomenon, this is the chick.1Day-old temperature, which is also the most suitable somatosensory temperature for chicks, must pay attention to humidity management at this time. In principle, humidity should be60-70%Of course, the humidity meter is also very important; and then the temperature and humidity are fixed in stable data, which is the temperature that the chicks need, which is the comprehensive embodiment of temperature and humidity.--That is, the body temperature is appropriate. If the humidity is too high, bathing is easy to occur. If the humidity is too low and the temperature is too high, dehydration is easy to occur. The thermometer display may be35It is also possible that38Degree, both the probe temperature and the temperature displayed by the thermometer are allowed to have errors; Only the temperature that the chicks adapt to is the brooding temperature and the most practical temperature.
