摘要
封闭式鸡舍的照需要人工照进行调控,在育雏育成期减少照时间,可以控制鸡群的生长发育,而合适、稳定的照时间减少规律,可以减少鸡群的应激反应,使鸡群发挥更大的生产性能,在育雏期可以得到更好的体重达标率和均匀度,使鸡群发挥更优异的生产性能。通过对封闭式鸡舍育雏期的照时间采取不同的逐步减少规律试验,结果表明,在育雏前期,关灯时间固定,开灯时间按照每天递减的照降低规律效果更好。
        The illumination of the enclosed chicken coop needs to be controlled by artificial light, and the reduction of the illumination time during the brooding and incubation period can well control the growth of the flock. The appropriate and stable light time reduction rule can reduce the stress response of the flock so that the flock can exert greater production performance. In the brooding and incubation period, better weight standard rate and evenness can be obtained, so that the flock can play more excellent production performance.In this study, different step-by-step reduction rule tests were conducted on the illumination time of the enclosed chicken house in their brooding period. The results showed that : in the early brooding period, the illumination reduction rule that turn off the light in a fixed time and decrease the turn-on time day by day has a better effect.
