由农业工程师,加拿大计划服务。光照强度(光照强度)和光照时间(光周期)是影响家禽生产的重要因素。强度影响摄食和攻击,以及进食和进水,而光周期影响生殖和产蛋周期,总进食量和生长速率。
在工作平面上的光强度(鸟级,蛋收集表,工作台水平等)用力士或脚烛光(10力士等于一英尺烛光)测量。
在肉鸡和蛋鸡手术中发现的典型光照水平约为10至20力士(1至2英尺烛光),而盛夏的阳光明媚的一天约为80000力士(8000英尺烛光)。办公桌表面的典型光照水平可以是400到500力士(40到50英尺烛光)。
光周期的变化用于刺激鸡群繁殖和商业蛋鸡产卵。在肉鸡(鸡和火鸡)中,正在研究几种不同的照明程序,以帮助通过饲料摄取改善骨骼发育。
在白天的黑暗中,使用比黑暗时间多的照明程序需要在风扇和进气口上设置光阱。
下面的表格提供了一些不同类型的家禽操作中最常见的照明程序。
