本试验旨在研究在秋冬非繁殖季节，不同光照时间对籽鹅种鹅血清生殖激素水平的影响及其变化规律，探讨通过控制光照时间调控籽鹅反季节生产的可能性。选择2年龄健康籽鹅300只(母鹅180只、公鹅120只)，分成3个组，每组母鹅60只、公鹅40只。对照组光照为自然光照；短光照组光照时间控制为11 h光照13 h黑暗(11L∶13D)；长光照组光照时间控制为15 h光照9 h黑暗(15L∶9D)。预试期1周，正试期10周。结果表明：增加光照时间能提高母鹅血清卵泡刺激素( FSH)、黄体生成素( LH)和公鹅血清睾酮( T)水平，母鹅血清催乳素( PRL)水平先升高后降低；长光照组鹅的各激素水平在试验结束时均接近对照组鹅繁殖期的各激素水平。减少光照时间则降低了母鹅血清FSH、LH和公鹅血清T水平，但提高了母鹅血清PRL水平。由此可见，光照时间影响了非繁殖季节籽鹅种鹅血清生殖激素水平，且不同光照时间下籽鹅种鹅血清生殖激素水平随光照时间变化呈现相应的变化规律，因此，未来可通过人工调控光照时间促使籽鹅在非繁殖季节生产。

This experiment was conducted to study the variation of serum reproductive hormone levels of breed-ing Zi geese in un-natural breeding season, and sought for the possibility of lighting time affecting anti-seasonal breeding of Zi geese. A total of 300 two-year-old breeding Zi geese (female 180, male 120) were divided into 3 groups ( female 60 and male 40 per group) . Geese in the control group were natural lighting, and the others in short lighting group and long lighting group were controlled with 11 h lighting and 13 h darkling and 15 h lighting and 9 h darkling, respectively. The preliminary trial period lasted for 1 week and trial period lasted for 10 weeks. The results showed that the levels of follicle-stimulatingg hormone ( FSH ) , luteinizing hormone ( LH) in serum of female geese and testosterone ( T) in serum of male geese were increased with the increas-ing of lighting time, and the serum prolactin ( PRL) level of female geese was increased at the beginning and then decreased with the increasing of lighting time. The hormone levels of geese in long lighting group were approached to the hormone levels of geese in control group at the experiment end. When the lighting time re-duced, the levels of FSH and LH in serum of female geese and T in serum of male geese were decreased, but the serum PRL level of female geese was increased. In conclusion, lighting time can affect the reproductive hormone levels of breeding Zi geese in the anestrous season, and the reproductive hormone levels of breeding Zi geese are varied in different lighting time. Therefore, the anti-seasonal reproduction of Zi geese will come true by artificial regulation lighting time.
