摘　　要：对两个兔场分别采用不同加光方式的哺乳期母兔生产性能做一个对比,他们都使用暖白氦气灯和冷白色的LED灯（光照强度在40~50Lux或50Lux）。这两个兔场都采用42天（产后11天人工授精）繁殖模式,日常光照9h。这两个兔场都是在人工授精前8天增加光照时间到16h,人工授精后3天逐步减到9h。在Galgamacsa兔场,6-10月期间,使用暖白色氦气节能灯的兔舍光强度增强到55~80 Lux,使用LED灯的兔舍光照强度增加到100Lux。在Kartal兔场,7-8月份,使用氦气节能灯的兔舍和使用LED灯的兔舍都没有增加光照强度,只是延长光照时间。Galgamacsa兔场,在夏季使用LED灯的母兔受胎率（91%）和产仔率（83%）比使用氦气节能灯的母兔（受胎率85%-87%,产仔率78%）高出5%（P〈0.05）.在Karta兔场,这种差异不显著,只是高出1%~2%。Galgamacsa兔场,使用LED灯的母兔产活仔数量为10.6~11只,使用氦气节能灯的母兔产活仔数量为10.3只。Karta兔场,使用LED灯的母兔产活仔数量为8.8~8.9只,使用氦气节能灯的母兔产活仔数量为8.7只。Galgamacsa兔场在夏季使LED灯的母兔总体生产性能是最高的,人工授精100只母兔,产活仔782只。使用LED灯和在人工授精前后增加光照强度和光照时间,在夏季提高哺乳期母兔的生产性能是可行的。试验证实,在人工授精的时候,光的特性对调整母兔的光照刺激是很重要的。The production of controlled nursing rabbits subjected to 9 h basal daily lighting with warm-white ne- on or cold-white LED lamps（light intensity 40- 50 or 50 lux）was compared at two rabbits farms differing in photo-stimulation before AI（on day 11）.At both farms on day 8 before AI the daily lighting was increased to 16 h and from day 3 after AI it was gradually reduced to 9 h.At Galgamacsa farm （June-October）the light intensity was also enhanced by using warm-white compact saving lamps to 55 - 80 lux in neon-lighted units or by set- ting the LEDs to 100 lux in the LED-lighted units.At Kartal farm （July-August） there was no supplemental lighting,i.e.the light intensity was not changed in the neon or LED-lighted units,only the duration of the daily lighting was increased.In summer at Galgamacsa, pregnancy （91%） and kindling rates（83%） were 5% higher（p〈 0.05）with LED than with the neon plus saving lamp photo-sstimulations （85-87% and 78%）.At Kartal, the 1% - 2% differnces in favor of LED lighting were not significant for these traits. The number of kits born alive creased day length and light intensity around AI）. the summer production of controlled nursing rabbits was improved .These results confirm the importance of light characteristics when stimulating rabbits does at AI by modified lighting.
