Abstract:This study investigated the possibility of increasing illumination time to improve the reproductive performance of the Chinese monals (Lophophorus lhuysii) during the breeding season. Artificial supplementary lighting tests were conducted during February 26 to May 26, 2016. A total of 8 adult L. lhuysii(4, 4♀) with the similar mass and size were chosen and randomly divided into an experimental group (2, 2♀) and a control group (2, 2♀). Natural lighting was used in the control group, and in the experimental group, the natural lighting and artificial supplementary lighting were combined and the illumination time was extended to 16 h (16L:8D) per day. The results showed that the blood estradiol of female L. lhuysii and the blood testosterone of male in the experimental group were extreme significantly higher than those in control group (P<0.01). The blood luteinizing prime and prolactin in experimental group were significantly higher than those of control group (P<0.05). The blood follicle stimulating hormone of experimental group was higher than that of control group, but the difference was not significant (P>0.05). The courtship behavior of the males in experimental group appeared more early and frequently than that of control group. The first spawning date in experimental group was 26 d earlier than that of control group, the spawning period delayed 2 d, the fertility rate went up by 80%, the average egg mass increased 3.0 g, and the egg laying number increased 1. On the basis of L. lhuysii annual spawning, combined use of natural lighting and artificial supplementary lighting can promote L. lhuysii to lay eggs, increase the egg weight, and increase the fertility rate.
