The light color has different light color and different wavelengths, and the effect on laying hens is also different. Tests have shown that, under the same conditions for other feeding conditions, the egg production rate of hens reared under red light is significantly increased, generally about 20%.
The length of time that is appropriate for supplementing the hens is usually from the age of 19 weeks. The duration of the illumination should be from short to long, and it is advisable to add half an hour each week. When the daily light time reaches 16 hours, stable light should be maintained, not for a short period of time. The best way is to supplement light every morning and evening.
The light intensity is uniform and suitable for normal laying hens, the required light intensity is generally 2.7 watts. Multi-layer cage chicken sheds are designed to provide sufficient illuminance for the bottom layer. The illuminance at the time of design should be increased, typically 3.3 to 3.5 watts per square meter. Therefore, the installation of light bulbs in the chicken house should be 40 to 60 watts. It is usually 2 meters high and 3 meters away from the lamp. If two or more rows of light bulbs are installed inside the house, they should be arranged crosswise. The distance between the light bulb against the wall and the wall should be half the distance between the bulbs, and attention should be paid to replacing the damaged light bulbs at any time. The bulbs should be wiped once a week to keep them inside. Appropriate brightness.

Degradable plastics refer to a kind of plastics whose products' various properties can meet the requirements of use and their properties remain unchanged during the preservation period. However, they can be degraded into environmentally harmless substances under natural environmental conditions after use. Therefore, it is also known as environmentally degradable plastics.
Existing a variety of new plastics: photodegradable plastic, biodegradable plastic, light, oxidation \ biodegradable plastic, carbon dioxide-based biodegradable plastic, thermoplastic starch resin degradable plastic.
