Effects of Different Light Duration During Pregnancy: Experimental Study

Objective: The aim of the study was to investigate the effects of the same intensity and wavelength of light applied in addition to the daily light period on pregnant rats. Material and Methods: An experimental model was established using primigravida rats (Wistar Albino) to investigate the effects of an additional 4-hour light exposure beyond the daily light cycle on the physiological and behavioral parameters of both mothers and newborn offsprings. The study was designed with a control group receiving a 12/12 hour light cycle and an experimental light group receiving a 16/8 hour light cycle. A total of 12 pregnant, with 6 in each group, were utilized. Results: No significant difference was observed in body weight gain between the groups (p>0.05); however, feed and water consumption differed significantly (p
