Safe feeding of broilers and strict control of temperature difference

The temperature difference is usually simple, but it is not easy to control it effectively throughout the chicken feeding process. The temperature difference is usually as follows:

Spring temperature difference

⑴ is characterized by low humidity, large temperature difference and windy in spring.

Key points of ⑵ feeding and management

Increase the humidity of the chicken house (especially the chicken house heated by the air heater) until the chicken can not relax; the chicken coop with a width of less than 13 meters is mainly ventilated by natural ventilation, supplemented by the appropriate use of top fan and side fan, and the air intake should not be too large, and the ventilation should be adjusted according to the change of your external temperature at any time.

Summer temperature difference

The characteristics of ⑴ in summer-- the coexistence of dry heat and damp heat

Key points of ⑵ feeding and management

Mainly to cool down. In early summer, the weather is easy to be suddenly hot, so longitudinal fans can be used to ventilate and cool. At this stage, we should pay attention to the fact that although the external temperature is already high, the wind speed and temperature is still cooler. We should pay attention to the fact that the air inlet cannot blow the chicken directly, let alone let the wind pass through the belly of the chicken from under the net. With the increase of temperature and humidity, the water curtain is gradually used to cool down. At the initial stage of use, attention should be paid to slow use to prevent the water curtain from getting too cool (the cool breeze of the wet curtain can be neutralized by adjusting the number of fans and the small windows around the water curtain). After entering dog days, open up the use of all cooling equipment, including fans, wet curtains, fog lines and so on.

Autumn temperature difference

The characteristic of ⑴ autumn-the temperature difference increases gradually, it is wet and windy in early autumn.

Key points of ⑵ feeding and management

The most difficult thing to master in autumn feeding management is ventilation. High temperature and humidity should be cooled mainly in early autumn, and it is a process of heat preservation in late autumn. Therefore, the principle of autumn ventilation is the first choice of natural ventilation, followed by top fan ventilation, then inverted fan ventilation, and then inverted main fan ventilation.

Matters needing attention of ⑶ Autumn ventilation

① preferred natural ventilation, such as the environment can not be controlled, and then use mechanical ventilation, must be slowly opened and gradually increased.

② air intake should not be large, keep the breeze open.

③ external temperature is the first standard of ventilation, so the fan should be turned off in time.

④ is ventilated from the back. ⑤ is heated and ventilated.

In case of cooling weather, ⑥ must heat up ahead of time and close the vents.

The concentration of ammonia in ⑦ is higher in autumn than in summer, and people suddenly enter the henhouse with a certain smell, but there is a principle that can not go beyond "can make the nose feel the taste, but must not make the eyes feel uncomfortable."

⑧ when the longitudinal fan and the side fan are used, the sewage outlet of the skylight, the top fan and the chicken house will become an air inlet. Pay attention to whether the temperature of the chicken in these positions is suitable.

Winter temperature difference

The characteristics of ⑴ in winter-- the weather is getting colder, drier and windy

Key points of ⑵ feeding and management

The most important thing in winter is to test the sealing and heat preservation of the chicken coop. At this stage, we should pay attention to:

① temperature difference will form the wind, whether the cool breeze coming from the vent directly blows the chicken.

② should pay attention to the formation of water droplets on the walls, roofs and partitions of the henhouse in late autumn and early winter. Where water droplets can be formed, cool air will infiltrate into the henhouse in winter, causing the temperature difference in the henhouse to widen and some chickens to catch cold.

③ winter vents usually use a feed bag without an inner bag to cover the upper part of the wind to turn the gale into a slow wind and a strong wind into a breeze, while providing oxygen to the chicken coop.

④ adds humidity to the henhouse appropriately, especially for chickens before 20 days of age.
