2. Drinking water: Observe the growth of chicken at any time during the breeding period. Adjust the area of ​​drinking water and the height of the water pipe as the size of the chicken increases to ensure that the chicken has sufficient clean drinking water.
3. Light: There is a very close relationship between the amount of egg produced by a chicken and the length of light received by a hen throughout the day. The number of eggs, the size of the eggs, the survival rate and the total profit are all affected by the light.
In the first week the chicks were exposed to light for 20-22 hours a day and the light intensity was 30 lux. The second week, the illumination time was reduced to 20 hours and the light intensity was 5 lux. The lighting time was gradually reduced to 9 hours per day at the next time. Until 7 weeks old. From 7 to 15 weeks of age, the duration of light is constant at 9 hours and the intensity is 5 lux. At the age of 16 weeks, the light was increased by 1 hour per week, until it reached 18 hours and 11 hours, and the intensity was 10 lux. The adjustment of light intensity and time should be based on the development of the flock. Adult laying hens do not reduce light intensity or light time.
Before the birds reach a proper weight, no light stimulation measures can be taken. If the stimulating light is applied to chickens below the standard weight, the egg shape will become smaller, the peak duration will be short, or the egg production will drop too quickly after the peak. Light stimulation can be used as a means to obtain the size of the target egg shape. Usually the earlier light stimulation will increase the egg production per bird, but the egg weight is smaller. Later light stimulation reduced the total number of eggs, but the eggs in the early stages of laying were significant. In this way, adjusting the lighting program can better meet the market's demand for different egg sizes.
4. Midnight feeding: Illumination technology that increases feed intake is called midnight feeding. This technique is to give 1 hour of light at night, and at this time, start the feeder. A typical laying hen lighting system is 16 hours of light, 8 hours of darkness, 8 hours of nighttime splitting into 3.5 hours of darkness + 1 hour of light + 3.5 hours of darkness, and the procedure of 16 hours of lighting time has not changed. The one-hour lighting time can be implemented immediately. If you want to make a mistake, you should gradually adjust it for 15 minutes per week. Feeding at midnight usually increases the feed intake by 2 to 5 grams per day per bird. This technique is suitable for use in heat stress, but it can also be used when it is desired to increase feed intake during growth and laying.
5. The development of lighting procedures: When using an open chicken house, natural lighting will affect the flock, lighting system must change with the natural light time. Since no two places have the same sunrise and sunset times in a year, there is no timetable that can be applied to all regions. Growing chickens reach maturity in the spring where light is gradually prolonged. In order to prevent premature sexual maturation, the natural illumination time at the age of 16 weeks was found, and an artificial illumination system between 8 and 16 weeks of age was established based on the specific values.
6. Temperature: The temperature in the house should be stable and cannot be changed. The 7-week-old shepherd's temperature should be above 22°C, 8 to 18 weeks old, and the temperature can be maintained at 18°C ​​to 24°C. Pay attention to the temperature difference in winter and make adjustments in time.
7. Ventilation: Ventilation can reduce the concentration of harmful gases and microorganisms in the house and provide fresh air to the flock. Therefore, the ventilation of the house should be done under the premise of ensuring the temperature.
8. Feeding density: During the breeding period, the stocking density of the flock should be observed at any time and adjusted according to the growth of the chicken.
9. Environmental Control: At any time during the breeding period, the inside and outside of the house should be cleaned, and disinfection and epidemic prevention should be done.
