Ventilation skills for breeding broilers, ventilation skills for raising broilers, ventilation skill

In the vent to place a wind shield Mainly used at night with a large temperature difference to prevent cold air (temperature difference cold air) from blowing directly on the chickens Mainly the head In addition, your chicken shed should not be too long at most 50 meters If it is more than 50 meters, it is easy to have problems with raising chickens, including respiratory tract and viral diseases are common, so I recommend that your chicken shed should not be too long. In addition, when ventilating, the temperature difference between 10 days and 15 days old can be ventilated at one to two degrees, but if the temperature difference is ventilated at two degrees, it depends on the condition of the chickens, if the physique is good, it can be ventilated at two degrees, and the temperature at night is one degree higher than the daytime, because the chickens rest more at night, in order to prevent the chickens from being cold, the night is the most critical, and the room temperature should be kept one degree higher than normal on the night after the vaccine and the next three days (including night and daytime) chickens have a habit of sticking their mouths under their wings, chicks are rare, but big chickens are more common, this is a big chicken, mainly afraid of the head cold, so when the big chicken is more careful, do not let the cold wind blow its head.

1. The chick enters the chicken on the third day, you can open the window for ventilation, don't play too big, each window is 2 cm gap, you can also play a little smaller in winter, a flat finger on the line, 2, the chick to about 15 days, the wind can not be too big, do not cause the respiratory tract, so as not to affect the seedlings, it is advisable for people to enter the chicken coop without suffocation, in addition, the temperature difference between indoor and outdoor in winter is large, and the convection speed of the air is fast, so there is no need to play too big to bring traces to achieve the purpose of ventilation. In winter, the cold air comes in through the window and goes straight down vertically, and gradually rises after being heated by the indoor air.

3. After 28 days of chickens, the wind can be appropriately increased, especially during the day in summer, the window can fall to the back of the chicken, and the window is open about 50-80 cm, and it is good to blow it on the stomach.

After the day, the chick feathers are full, and the window can be lowered to the bottom in the summer, and it is fully ventilated

<>1. A wind shield should be placed in the vent, mainly used at night with a large temperature difference, to prevent cold air (temperature difference cold wind) from blowing directly on the chickens, and the main coarse lead is the head. In addition, your chicken shed should not be too long, at most 50 meters, if it is more than 50 meters, it is easy to have problems with chickens, including respiratory and viral diseases, which are common, so it is recommended that your chicken shed should not be too long.

2. In addition, when ventilating, the temperature difference between ten days and fifteen days old can be ventilated at one degree, and the temperature difference between ten and fifteen days old can be ventilated at one to two degrees, but if the temperature difference is good at two degrees, it depends on the situation of the chickens, and if the physique is good, it can be ventilated at two degrees of temperature difference, and then the temperature at night is one degree higher than that during the day. Because the chickens rest more at night, in order to prevent the chickens from being cold, the night is the most critical.

3. In addition, the night after the vaccine and the next three days should also keep the room temperature one degree higher than normal, (including night and day) chickens have a habit of inserting their mouths under the wings, chicks are rare but big chickens are more common, this is the big chicken is mainly afraid of the head cold, so the big chicken should be more careful not to let the cold wind blow its head.

1. A wind shield should be placed in the vent, mainly for use at night with a large temperature difference, to prevent cold air (temperature difference cold wind) from blowing directly on the chickens, mainly the head. In addition, your chicken shed should not be too long, at most 50 meters, if it is more than 50 meters, it is easy to have problems with chickens, including respiratory and viral diseases, which are common, so it is recommended to celebrate: your chicken shed should not be too long.

2. In addition, when ventilating, the temperature difference before the age of ten days can be ventilated at one degree, and the temperature difference between the age of ten and fifteen days is ventilated at one to two degrees, but if the temperature difference is ventilated at two degrees, it depends on the situation of the chickens, and if the physique is good, it can be ventilated at two degrees of temperature difference, and the temperature is one degree higher than that of Bicha during the day. Because the chickens rest more at night, in order to prevent the chickens from getting cold, the night is the most critical.

3. In addition, the night after the vaccine and the next three days should also keep the room temperature one degree higher than normal, (including night and day) chickens have a habit of inserting their mouths under their wings, chicks are rare but big chickens are more common, this hand is stupid is that the big chicken is mainly afraid of the head cold, so the big chicken should be more careful not to let the cold wind blow its head.

1. The chick enters the chicken on the third day, you can open the window for ventilation, such as don't hit too big, each window is 2 cm gap, and you can also play a little smaller in winter, just a flat finger, 2, the chick to about 15 days, the wind can not be too big, do not cause the respiratory tract, so as not to affect the seedlings, it is advisable for people to enter the chicken coop without suffocation, in addition, the temperature difference between indoor and outdoor in winter is large, and the air convection speed is fast, so you don't need to play too big to achieve the purpose of ventilation. In winter, the cold air comes in through the window and goes straight down vertically, and gradually rises after being heated by the indoor air.

3. After 28 days of chickens, the wind can be appropriately increased, especially during the day in summer, the window can fall to the back of the chicken, the window is open about 50-80 cm, and the slag blowing is not enough to the stomach.

After the day, the chick feathers are full, and the window can be lowered to the bottom in the summer, and it is fully ventilated

After the day, the chick feathers grow full, and the window can be lowered to the end in summer, and the ventilation is fully ventilated

1. Time management, it should not be difficult to understand, mainly ventilation time, involving fan circulation time, fan opening time and fan closing time.

As we all know, the ventilation required by broilers at different ages is generally expressed as a percentage, that is, as a percentage of the exhaust air volume of the fan used.

For example, a chicken flock 21 days old, 30,000 chickens per house, weighing kilograms, the outside temperature is about zero degrees, at this time the ventilation required per kilogram of broiler is calculated according to cubic meters per hour, if the exhaust air volume of the fan used at this time is 37,000 cubic meters per hour, the calculation can know that the percentage of broiler ventilation required at this time is.

Finally, the wind turbine operating time is finally determined by the cycle time performed by the fan. Depending on the cycle time, the amount of ventilation supplied to the broiler does not change, but the way the fan operates is different.

If the fan starts for eight minutes and the required fan opening time is 8*60s*, the fan stop time is 480-209=271 seconds.

Similarly, for a five-minute cycle, the fan is turned on for 131 seconds and stopped for 169 seconds. Every three minutes, the fan is turned on for 78 seconds and stopped for 102 seconds. Every two minutes, the fan is turned on for 52 seconds and stopped for 68 seconds.

Question: Is it okay to use a time-controlled 2 fan at the age of minus 10 degrees Celsius 36 days?

Ask how you calculated the 47 percent above.

You don't have to ask a question.
