Chicken lamp is a kind of lamp which uses artificial light color information to improve the growth and production performance of poultry according to the particularity of poultry vision and light information processing and the influence of light sources with different wavelengths on the physiological functions of broilers and laying hens.
The necessity of raising chickens to make up the light;
Birds have two photoreceptors, one is the retinal receptor, which is the eye, and the other is located in the hypothalamus. The stimulation of light reaches the hypothalamus through the nerves in the optic lobe; In addition, light can also directly act on the pineal gland and hypothalamus through the skull. After stimulation, the hypothalamus secretes gonadotropin-releasing hormone, which reaches the anterior pituitary through the pituitary portal system, causing the secretion of follicle-stimulating hormone and ovulation hormone, and promoting the development and ovulation of follicles. The developing follicle produces estrogen, which promotes the development of oviduct and the appearance of secondary sexual characteristics in hens. Ovulation hormone causes hens to ovulate.
In the production of commercial laying hens, artificial illumination is often used to supplement the shortage of natural illumination, or only artificial illumination is used to reasonably adjust the illumination required by laying hens. Proper light can improve the egg production of laying hens, accelerate the weight gain of broilers, strengthen blood circulation, increase appetite, contribute to calcium and phosphorus metabolism and enhance immunity.
Effect of monochromatic light on performance of broilers;
Using green light irradiation in the early growth stage and blue light irradiation in the late growth stage can significantly promote the growth and development of broilers and improve their production performance. There are also some reports about the effects of different monochromatic light on the immune function of spleen cells in broilers. Blue light can obviously improve the immune function of spleen cells in broilers and reduce immune stress.
Development of chicken lanterns at home and abroad;
The new series of red, light blue and green single lights successfully developed by Gasolec company in the Netherlands can meet the production requirements of different poultry, and the working cycle can exceed 65,438+00,000 hours. Since 1997, this series of lighting equipment has been successfully applied in more than 30 countries in the world. After more than two years of popularization and application of more than 20 chicken farms in Russia, the effect is very good and it is quite popular.
At present, most chicken farms in China use 40W incandescent lamp as lighting source, which has low luminous efficiency and high power consumption. China is vigorously promoting energy conservation and emission reduction, and incandescent lamps are gradually withdrawing from the market, so incandescent lamps will soon withdraw from the field of farm lighting sources.
A small number of aquaculture enterprises use 28W energy-saving lamps for lighting, and the light color is white, which only plays a lighting effect. However, the fluorescent powder of energy-saving lamps contains mercury, and the lamp body is easily broken, and the residual mercury molecules are not easy to remove, which will pollute the environment. 201165438+February, Harbin Filson energy-saving equipment technology development co., ltd developed and produced the "Filson" brand LED chicken lamp, with a power of 4W, a service life of 30,000 hours, and a power consumption of only one tenth of that of a 40W incandescent lamp. (The green light flux is more than 25% of that of 40W incandescent lamp), and the product fills the gap in the domestic market. 1. Compared with ordinary incandescent lamps, Firston FI lamp can increase the weight of each batch of meat birds by 5.5%. In the early growth stage, the feed and meat were relatively low, only 1.80.2. Firston FI lamp can increase the number of goblet cells in small intestine epithelium of meat birds, promote the proliferation of epithelial cells and improve production performance. 3. the 3.Firston FI lamp can make the broilers in a state of nervous stress quiet for 3 ~ 6 hours in the first few days of entering the henhouse, and at the same time start to eat actively. 4.Firsson FI lamp can improve the disease resistance of meat birds. Compared with ordinary white light lamp, the weight of chicken spleen increased by 22.6%. 5. The weight of each batch of broilers under FI lamp is 5.6% higher than that under white light. It provides a new LED light source with energy saving, environmental protection and yield increase for domestic poultry farmers.
