The lighting technology for raising chickens has been developedRaising chickensTo ensure the effectiveness of the technology, it is necessary to grasp one principle, control two checkpoints, grasp three key points, pay attention to four links, and establish an overall lighting program.
(1) PrincipleThe illumination time and intensity must be in accordance withchickenThe physical maturity, sexual maturity, and production stages are consistent.
(2) Gateway: Chickens should not be exposed to prolonged light during their growth period, and the light exposure during their egg laying period should not be shortened& nbsp; The illumination should be uniform, the reflection should be normal, and the intensity (excluding the illumination time, bulb power, quantity, distance, color, etc.) should be appropriate.
(3) Key: The light exposure time is generally 8 hours per day during the growth period, and should not exceed 11 hours per day; The egg laying period can reach 14 h/d to 16 h/d. The optimal light intensity during the growth period is 5 lx to 10 lx (with a light bulb 2 meters above the ground and a 40 W light bulb with a good reflective lampshade installed every 15 m2 in the chicken coop, the light intensity for the chickens is 10 lx), and during the egg laying period, 10 lx is appropriate. The distance between light bulbs should be 1 5 times, the distance between the lamp and the wall should be 1/2 of the distance between the bulbs. Light color: Generally, large chickens use white light, while small chickens can use red light.
(4) Step: Subtract the natural daylight exposure time of the local area from the required light exposure time for the chicken, and make up for the difference. If there is no difference, make up for it. Supplement the light once before dawn; Shortening the illumination time can be achieved by covering it with a curtainhenhouseTo achieve. The control methods for light intensity are flexible and diverse, such as increasing or decreasing the number of light bulbs, replacing bulbs of different powers, adjusting voltage, etc. Every time the lights are turned on or off, the light should gradually shift from dark to bright and from bright to dark, allowing the chickens to adapt slowly and prevent them from being startled and causing stress reactions. Chickens are sensitive to the color of light sources and should be given sufficient attention. Under red light, chickens tend to be quiet, have less pecking habits, mature slightly later, and have slightly increased egg production, but have a lower fertilization rate; Yellow light delays sexual maturity in chickens, reduces egg production (but increases egg weight), and increases pecking habits; Green light can advance the sexual maturity of chickens, enhance their mating ability, and result in faster weight gain; Blue light can improve the reproductive ability of roosters, but the egg production of hens decreases.
(5) Overall lighting program:;From the day of hatching to 3 days old, the laying hens were exposed to 23 hours of light and maintained at a light intensity of 10 lx; When chickens are between 4 and 14 days old, the light exposure time is 18 hours and the light intensity is 5 lx; Afterwards, the weekly light exposure time will be shortened by 2 hours until all natural light is used (light methods can be used appropriately to shorten the light exposure time during the breeding period). Chickens at 18 to 21 weeks of age need to increase their light exposure time by 0 5 hours. After reaching 22 weeks of age, chickens increase by 0 From 5 hours to the peak of egg production, the total daily light exposure time is 15-16 hours. For the remaining 4 weeks of the egg production period, it can be increased to 17 hours, and the light intensity should be 10 lx. The principle of lighting for raising broiler chickens is to ensure their normal activities, feeding, and drinking water. The light does not require too strong, and it is better to use dim light. Red light bulbs can be used for illumination, with an area of 18-20 m2 per 18 m2henhouseUse one bulb with a power of 15 W to 25 W. Chickens should be illuminated overnight before 4 weeks of age; After 4 weeks of age, turn off the lights after feeding at night and use natural light during the day.
