This experiment was carried out to investigate the effect of light-cycle control on fertility and hatchability of pheasant eggs. At the age of 24 weeks, three groups of 25 females and 5 males each were assigned to each of the following three day light regimes: (A) natural daylight; (B) 4-week non-stimulatory fight cycle 18-hr light/ L6-hr dark) and then stimulatory light (8-hr dark/16-hr light); (C) 8-week nonstimualtroy light cycle and then stimulatroy light cycle. Fertilities of eggs produced by treatments A, B and C during the entire 12-week period were 73.4, 70.2 and 69.6%, respectively and were not influenced by the treatment (p$lt;0.05). However mean fertilities of eggs produced by treatment groups were in the range of 77.3∼81.1, 67.5∼78.1 and 49.4∼66.4% during the lst, 2nd and 3rd period (4 weeks/period) following the first egg found, respectively, indicating that fertility decreases with time following the first egg production. Mean 12-week hatchabilities for treatments A, B and C were 69.4, 79,5 and 78.9?., respectively and were not different between the treatments (p$gt;0.05). Chick weights at hatch of eggs produced during the 12-week period were 17.0, 14.5 and 16.6 g for treatments A, B and C, respectively. Ratios of chick weight to egg weight over the 12-week period were 0.66, 0.62 and 0.64 for treatments A, B and C, respectively (p$gt;0.05). Results of these studies showed that no apparent adverse effects of inducing early egg production on fertility and hatchability were found.
