The objective of this experiment was to investigate the effect of light flashes on the reproductive performance of New Zealand white rabbits. A total of sixty two rabbits aged 24 weeks were randomly distributed into three experimental groups (24 rabbit each). The rabbits in control group (C) were exposed to constant light (12 h Light: 12 h Dark). In the other treated two groups, the 12 h of daylight period was divided into 6 h (constant light) and 6 h (flashes of light) for either 15 min. / h (T1) or 30 min. / h (T2). Based on the results, significant (P≤0.05) effects were observed in conception rate and reproductive index of flashed light treated groups. Also, light flashes induced significant increases in rectal temperature, health risk and sperm-cell concentration. However, no significant differences were demonstrated in most semen traits, gestation period, litter size, bunny weight, blood parameters values and mortality rate. It concluded that the most suitable lighting program for reproductive performance of rabbits is the flashes of light (15 min/hour), because it was more economically efficient than continuous or flashes of light (30 min/hour).
