Several aspects of broiler breeding need to be controlled
Dec 07, 2018

1, temperature

Temperature has a great influence on broilers. Especially for chickens, due to their poor ability to regulate body temperature, it is more important to maintain the appropriate environmental temperature during the brooding stage. Usually the temperature of the first three days is higher, which should be maintained at 32-33 degrees C, and then lowered by 1 degrees C per day until the temperature reaches about 21 degrees C. Attention should be paid to the smooth transition during cooling, so as to avoid the stress reaction of broilers caused by the sudden drop of temperature. If encounter rainy days, cold weather season, or during the period of immunization, the room temperature can be properly increased by 1-2 degrees Celsius. The time of chicken dewarming should be determined according to the ambient temperature, and after dewarming, it must be warmed up if the ambient temperature is reduced to 18 degrees Celsius. In aquaculture production, the determination of shelter temperature can be determined by the value of thermometer, but it also depends on the actual performance and health status of broilers to determine whether the ambient temperature is appropriate. Usually when the environmental temperature is suitable, the chickens distribute evenly, breathe calmly, eat and drink normally and sleep quietly; when the temperature is too high, the chickens show that they are far away from the heat source, breathe open their mouths, feed intake decreases, and water intake increases. At this time, they should reduce the house temperature properly; when the temperature is too low, the chickens show that they are close to the heat source and appear. If the phenomenon of heaping and heating is not dispersed in time, it will increase the number of chickens crushed to death. At this time, the temperature of chicken house should be raised immediately to ensure that the environmental temperature is suitable for the growth and growth of broilers.

2. Relative humidity

The effect of relative humidity on Broilers is smaller than other environmental factors, but it can not be ignored. If the relative humidity of the environment is relatively high, the house is too humid, which will make the chickens feel the lower temperature. If the ambient temperature is low, it will cause broilers to feel colder, which will lead to the decrease of feed intake and insufficient nutrient intake of chickens, while in high temperature environment, it is not conducive to the release of body heat. In addition, excessive humidity in the house also easily pollutes the bedding materials, causing a large number of pathogenic microorganisms to breed and reproduce, leading to chicken disease; if the relative humidity of the environment is too low, the house will be dry, easily leading to excessive dust in the house, causing respiratory diseases in the chicken flock, and easily leading to dehydration of the chicken flock, slow growth of feathers, etc. Weak constitution, etc. Usually the relative humidity of broiler house should be determined according to the different age of broiler. The relative humidity of broiler house is 65% - 70% in 1 - 10 days old and 65% in 11 - 30 days old. With the growth and development of chicken, it can be maintained at about 60% after 2 weeks old. For the control method of relative humidity in the henhouse, the adjustment should be made according to the measurement value. If the humidity is too low, the humidity inside the house can be improved by spraying water and spraying to the ground, but it is strictly forbidden to sprinkle water directly on the padding. If the humidity is too large, it is necessary to strengthen the management of drinking water and prevent leakage. At the same time, the intensity of ventilation and air exchange in the building should be increased, and the bedding materials should be changed frequently.

3. Illumination

Illumination plays an important role in the development of bone and feathers of broilers. Scientific and reasonable time and light intensity can improve the production performance of broilers. Broiler chickens grow rapidly in bone, muscle and feather after 7 days of age, and their metabolism is vigorous. This makes broiler chickens in a state of stress all the time. Therefore, the functional development of broiler chickens is not perfect and can not keep up with the rapid growth and metabolism, so they are prone to sudden death and ascites. In addition, the development of bone is slower than that of muscle, which can easily lead to leg disease in broilers. Therefore, the growth rate of broilers can be controlled by adjusting the illumination time and intensity, so that the development of bone, muscle and cardiopulmonary function of broilers can be more balanced, so as to improve the survival rate and production performance of broilers. In the first two days of brooding, 24 hours of illumination should be carried out with the intensity of 30-60 lx. The purpose is to let the chickens eat more and move more. With the growth and development of broilers, the illumination time should be gradually shortened. When the weight reaches 170g, the illumination time should be kept at 16-18 hours, 12-16 hours at 2-3 weeks of age, and increased to 4-5 weeks of age. At 18 hours, after 5 weeks of age, th was increased daily until 23 hours, and the light intensity remained at 5-10 lx. In terms of management, we should pay attention to the uniform distribution of illumination equipment in the house, and the power is not too large. It is advisable not to exceed 60W. If the lamp is raised on the net, the distance between the lamp and the chicken body is about 2m, and the distance between the lamp and the chicken body is about 3m.

4. Ventilation

Reasonable ventilation and ventilation can eliminate harmful gases in the building, control the temperature in the building and prevent the occurrence of diseases. Especially in intensive and large-scale farms, ventilation is more important. The ventilation rate of chicken house should gradually increase according to the growth of broiler's age. The purpose is to provide broiler with a fresh air, suitable temperature and relative humidity, which is beneficial to enhance the body's resistance and reduce the occurrence of diseases. In brooding period and cold weather ventilation should first raise the room temperature, so that ventilation can ensure that the temperature does not fall too low, not easy to make chickens cold, cold. In addition, when ventilating, cold air should not be allowed to blow directly into the chicken body, and at the same time, thieves should be prevented from entering. If the weather is hot and the ventilation can't meet the requirements, the ventilation and ventilation device should be installed in the house, and forced ventilation should be carried out to increase the air circulation speed.

5. Feeding density

The feeding density of broiler farming should be appropriate. If the density is too high, the temperature and humidity in the house will be too high, which is not conducive to heat dissipation and moisture removal. It will also lead to the increase of the concentration of harmful gases and the proliferation of pathogenic microorganisms, which will affect meat.Our Automatic chicken feeding machine is your best choice.
