Lighting Time Allocation<\/h4><p>Artificial lighting can employ flexible time allocation methods, the principle being to ensure accurate total lighting duration:<\/p><p><strong>Morning Full Supplementation<\/strong>: Turn on the lights before sunrise to supplement the required duration.<\/p><p><strong>Evening Full Supplementation<\/strong>: Turn on the lights after sunset to supplement the required duration.<\/p><p><strong>Morning and Evening Half Supplementation<\/strong>: Supplement half the time in the morning and half in the evening. This method helps stabilize the flock&#8217;s biological rhythms and reduce stress.<\/p><h4>2. Application of Automated Equipment<\/h4><p>Modern large-scale farms are advised to equip themselves with automatic lighting controllers. Such equipment can:<\/p><p>Arbitrarily adjust and set complex lighting programs.<\/p><p>Achieve precise sunrise and sunset simulation, allowing the flock to transition smoothly.<\/p><p>Reduce the inconvenience of manual operation and lighting errors caused by human error.<\/p><h4>3. Lighting Arrangement and Illumination Requirements<\/h4><p><strong>Uniformity and No Dark Spots<\/strong>: Regardless of cage mesh specifications, the spacing of the lights must be calculated to ensure uniform lighting throughout the chicken house, eliminating dark corners.<\/p><p><strong>Clear Visibility<\/strong>: Ensure that chickens can clearly see the water and feed lines from any location. This is a fundamental prerequisite for ensuring feed and water intake and flock uniformity.<\/p><p><strong>Stable Power Supply<\/strong>: The power lines in the chicken house must be convenient and stable, with emergency power supply capabilities to prevent power outages from affecting the lighting program.<\/p><p>Lighting management is an &#8220;invisible guide&#8221; throughout the chicken&#8217;s life. From gradually decreasing light during the brooding period to promote feed intake, to controlling development with constant or gradually decreasing light during the rearing period, each stage is closely interconnected. Only by deeply understanding the mechanism of light&#8217;s effect on chicken reproductive function and accurately implementing the lighting program according to the age of the flock and seasonal changes, in conjunction with stable and uniform supplemental lighting equipment, can the production potential of laying hens be truly maximized, achieving the breeding goals of high survival rate, high uniformity, and high egg production rate.<\/p>\t<\/div>\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t                    <\/div>\r\n        <\/div>\r\n        \t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>I.
