In the industry of raising chickens, the suitable temperature is one of the most fundamental conditions for raising chickens!
If the temperature is appropriate, the chicks will have a strong constitution, grow fast, and have a high feed application rate and a high survival rate;
if the temperature is too high, the chicks will have a reduced feed intake, drink too much water, and grow slowly;
if the temperature is too low, the yolk absorption of chicks will be poor, causing respiratory diseases, indigestion, increasing feed consumption, reducing feed reward, and significantly increasing the incidence of chest and leg diseases.
What is a dewarmed chicken seedling?
For farmers who want to shorten the chicken breeding cycle,Dewarmed chicken is a good choice.
Farmers usually buy chicken seedlings that have just hatched from the breeding chicken farm, while the de-warmed chicken seedlings are different from normal chicken seedlings, which are hatched and raised in the greenhouse for 15-20 days before being sold to farmers.
It is very important to control the hatching temperature and the temperature of the incubator after hatching, which is related to the survival rate of chicken seedlings and directly affects the economic income of chicken breeders.
Most of the traditional aquaculture heating is based on coal-fired boilers.
It often makes indoor smoke, which is not conducive to the growth of chicken seedlings, and also seriously pollutes the environment, and there will be uneven local temperature, affecting the healthy growth of chicken seedlings.
Requirements for design parameters in the chicken house?
Design parameters in the house 1. 1-2 days old chicks:
The chicks should be sent to the chicken house as soon as possible after they are transported.
During the 1-2 days of brooding, the temperature in the house should be kept at 34-35 ℃ and the relative humidity should be 70%.
In the first two days, 24-hour lighting should be used, and 40 W incandescent bulbs should be used for lighting.
2, that chick are 3-4 days old: the temperature in the house is adjust from the third day,
The relative humidity is maintained between 65-70%.
And 3. when that chick are 5-7 days old, adjust the temperature in the house to 32-30 deg C on the fifth day, and keeping the relative humidity at 65%. Feed 6 times a day, turn off the lights for 2 hours at night and keep 22 hours of light time.
From the seventh day, the net bed area was expanded to keep the number of chicks at 35 per square meter. And 4, when that chick are 8-14 days old, the temperature of the chicken house is reduce to 29 deg C from the 8th day.
- 15-22 days old: The temperature of the chicken house should be gradually reduced from 28 ℃ on the 15th day to 26 ℃ on the 22nd day.The temperature is reduced by 1 deg C in two days, and the humidity is controlled at 50-55%.
And 6. age from 23 to 26 days: when that age is 26 days, the temperature in the house is reduce to 25 deg C, and the humidity is controlled to be 45-50%.
- 27-34 days old: The room temperature should be reduced from 25 ℃ to 23 ℃, and the humidity should be kept at 40-45%.
8, 35 days old-slaughter: from 36 days old, the temperature of the chicken house was reduced to 22 ℃.
From 35 days of age to slaughter, 24 hours of light time should be maintained every day in order to increase the feed intake of chickens.
As to improve the weight gain speed of the chicken and lead the chicken to be sold in advance.
At the age of 37 days, the chickens are disinfected once, at the age of 40 days, the temperature of the chicken house is reduced to 21 deg C and maintained until the chicken is sold, and at the age of 42 days, the chickens are disinfected for the last time.
It is usually sold at the age of 42-45 days and weighs about 2.5-3 kg.
- A batch of chickens generally takes 42 days and about 15 days between two batches of chickens.
Cleaning, disinfection, preparation of materials and preheating generally guarantee that 6 batches of chickens will be produced in one year, and strive for 7 batches of chickens.
The use of air energy heat pump products in chicken farms can save worry, energy and the environment.
